Millet Seed Technology

F O R E W O R DSeed plays a critical role in increasing agricultural productivity; it determines the upper limit
of crop yields and the productivity of all other agricultural inputs to the farming system. The quality seed with high genetic and physical purity, germination, vigor and viability assures the potential of crop production under suitable and favorable agro-climatic conditions. The purity of commercial seed depends on genetic purity of parental lines in nucleus, breeder and foundation seeds in the generation system of seed multiplication. Standardizing seed production technology of new and existing hybrids in relation to agro-ecology, provenance (places most suited for seed production) and suitable techniques in seed production ensures better seed set, profitable seed yield and availability of best quality seeds in the seed trade. But problems in hybrid seed production always relate to the problems in synchrony of the parental lines and the techniques to achieve the same.
Millets (sorghum, pearl millet and small millets) are the important food and fodder crops in semi-arid regions, and are predominantly gaining more importance in a world that is increasingly becoming populous, malnourished and facing large climatic uncertainties. These crops are adapted to wide range of temperatures, moisture-regimes and input conditions supplying food and feed to millions of dryland farmers, particularly in the developing world. Besides they also form important raw material for potable alcohol and starch production, in addition millets are the best candidates to address the millennium goal of “Zero hunger”. To meet nation’s food security needs, it is important to make available to Indian farmers superior quality seeds of all crops including sorghum. Farmers as vital links in seed production, distribution and exchange networks are in search of resultant profitability from the seed production activity. Due to the seed production problems compounding in relation to ecological, agronomic and genetic limitations; the seed set, yield and resultant quality are also affected. In the absence of relevant technological knowledge, the sustained profitable yields and quality traits are at real stake. Hence, strategies to improve seed production, quality and supply must begin with strengthening the public agricultural R&D sector on a long-term, sustainable basis. It will be especially important to build the capacity to move from homogeneous seed recommendations to the development and dissemination of varieties targeted to specific agro-ecological zones and the needs of different groups of farmers.
This book on “Millet Seed Technology” covering both practical and theoretical aspects Seed Production, Quality control & Legal compliance deals in detail on major problems and management aspects related to hybrid and varietal seed technology of sorghum and millets respectively, including seed quality control, testing and legislation to help all the stakeholders to produce better quality seeds to ensure availability and profitability. I congratulate all those involved in bringing out this very useful publication.

different areas of Africa. Sorghum is one of the main staple food for the world’s poorest and most food insecure people across the semi-arid tropics. Globally, sorghum is cultivated on 41 million hectares to produce 64.20 million tones, with productivity howering around 1.60 tonnes per hectare. With exceptions in some regions, it is mainly produced and consumed by poor
peasant farmers. India contributes about 16% of the world’s sorghum production. It is the fourth most important cereal crop in the country. In India, this crop was one of the major cereal staple during 1950’s and occupied an area of more than 18 million ha but has come down to 7.53 million ha. The overall increase in productivity in kharif sorghum is far more than the same of rabi sorghum. However, both the loss in area and production is greater in kharif sorghum than in rabi. The coverage with high yielding varieties (HYVs) of sorghum is nearly 80% in kharif and potential under moderate input is also high (4-6 t ha-1). In the rice fallows, under the zero tillage conditions, grain productivity is as high as 7 to 8 tonnes per hectare. The utilization of kharif sorghum grain as a raw material in various industries is increasing, given the limited prospects of rainy season (kharif) sorghum for human consumption. Post-rainy season sorghum is a highly valued food grain, and too expensive to be used as industrial raw material. The main industries currently using sorghum in India are the poultry feed, animal feed and alcohol distilleries while its usage is quite sporadic in starch and biofuel industry, but holds a great promise as non-glutenous health food.
Sorghum – Great Millet
Origin Sorghum bicolor (L.) Moench origin and
domestication has taken place in Africa about 5000 – 8000 years ago. Indian subcontinent is the secondary origin of sorghum. The evidence for its cultivation was discovered at Saurastra dating back to about 4500 years. Sorghum was probably brought to India from eastern Africa during the first millennium BC. It is reported to have existed there around 1000 BC. The sorghums of India are related to those of northeastern Africa and the coast between Cape Guardafui and Mozambique. A major step in the process of domestication of sorghum is the loss of the seed shattering characteristic (Mann etal., 1983). Harlan (1975) asserted that domestication of sorghum occurred over time and in several areas where it was probably ennobled
many times over several years. He envisions that early domestication occurred in an area extending from near the Ethiopian border, west through Sudan and up to Lake Chad. There is great diversity in this area as well as the presence of the primitive race bicolor (Harlan and de Wet, 1972).
AdaptationSorghum is the fifth most important cereal
crop in the world and grown on 44 million ha in 99 countries in Africa, Asia, Oceania, and the Americas. The Major sorghum producers are the USA, India, Nigeria, China, Mexico, Sudan and Argentina. Sorghum occupies 25% or more of arable land in Mauritania, Gambia, Mali, Burkina Faso, Ghana, Niger, Somalia and Yemen, and >10% of this area in Nigeria, Chad, Sudan, Tanzania and Mozambique.

Most of it is grown for direct human use (>55%). The grain is mostly consumed in the form of flat breads (Bhakri) and porridges (thick or thin); stover is an important source of dry season maintenance rations for livestock, especially in Asia; also an important feed grain (33%), especially in the Americas.
BotanySorghum (Sorghum bicolor (L.) Moench) is
grown worldwide for food, feed, fodder, fuel and for several industrial products such as starch, syrup, ethanol, lager beer and malt. In India, sorghum is the most important cereal crop grown across semi-arid zones. The development and release of sorghum hybrids in India since 1963 has resulted in quantum jump in productivity from 570 kg ha-1 in 1970’s to >1000 kg ha-1 in recent years. Sorghum hybrid developmental efforts encompassed temperate × tropical crosses by manipulating height and maturity genes, and the critical growth stages (seedling, flowering and grain filling).
Sorghum plant has a single solid erect stem supported by a strong adventitious root system (Figure 1). Sorghum can tiller, but tillering capacity
is dependent on the cultivar and environmental conditions, especially tillering is profuse at low temperature. The cylinder of stem with the clasping sheath is called as culm. The culm thickness at the base may vary from 0.5 to 5.0 cm in diameter with 0.5 to 4.0 m long in height, exhibiting series of nodes and internodes. Leaves are arranged alternately on the stem, usually in two ranks. Each leaf originates from a node and has a sheath and blade or lamina.
Sorghum plant morphologyThe leaf sheaths have overlapping margins and
encircle the internodes, depending on internode length. The leaf blade may be 1.5 to 13 cm wide and 30 to 135 cm long. Leaf number can vary from 7 to 30 depending on the cultivar and its growth duration. The uppermost internode bears the inflorescence and is called as peduncle. Sorghum is known as short–day plant, hence, long nights (dark period) are required for floral initiation; and each cultivar needs a specific critical period of darkness for transformation of its vegetative bud to into a floral bud. Length of maturity in sorghum is governed by four major genes (Ma1, Ma2, Ma3, and Ma4) called as maturity genes with multiple alleles at each of the four loci. Plant height is similarly controlled by four major genes called dwarfing genes (Dw1, Dw2, Dw3, and Dw4), which effect plant height due to reduction in internodal length. The interaction of height and maturity genes with changing photoperiod and temperature results in significant variation in crop morphology and behavior.Floral biology
The sorghum panicles may be 4–25 cm long and 2–20 cm wide, which may be short and compact or loose and open. The inflorescence is a raceme consisting of one or several spikelets. Racemes vary in length depending upon number of nodes and length of internodes. The sessile spikelet varies in shape from lanceolate to almost round and ovate and is sometimes depressed in the middle. The lower glume is usually somewhat flattened and

conforms more or less to the shape of the spikelet, while the upper one is more convex or boat-shaped. The seed may be enclosed by the glume or may protrude from the glume.
Parts of fertile sorghum spikelet
The seed may be just visible or almost completely exposed. In sessile spikelets, there are two lemmas, two lodicules and a palea. The pedicelled spikelets are much narrower than the sessile spikelets and are usually lanceolate. They are male or neutral in sex, but may rarely have a rudimentary ovary. The lemmas are much reduced in size and only rarely does the upper lemma have awn. Sorghum has 2 pistils and 3 stamens. Each fluffy stigma is attached to a short and stout style extending to the ovary. The anthers are attached to long thread like filaments.
Spikelets of sorghum. A: Pair of spikelets; B: Fertile spikelet
Anthesis and pollinationThe floral initiation (Primordial formation)
starts at 30 to 40 days after germination (but may range from 19 to 70 days or more) Floral initiation marks the end of the vegetative growth and the meristematic activity. Sorghum usually flowers in 55 to 70 days in warm climates, but it could be as early as 30 days or as late as 100 days or more. The flowering (anthesis) in a panicle starts from the top and it travels successively to lower whorls. Flowering is completed over a period of 4 to 5 days (6-8 days under cooler conditions).
Pollen is usually available for a period of 10 to 15 days because the heads in a field do not flower at the same time. Sorghum is predominantly a

self-fertilized crop, but the cross pollination may occur to an extent of 2 to 10 percent. At flowering, the glumes open and the three anthers fall free, while the two stigmas protrude, each on a stiff style. Flowering occurs just before or just after sunrise, but may be delayed on cloudy damp
mornings. The anthers dehisce when they are dry. For selfing, the panicle is merely covered with a paper bag. Pollen is shed freely and can always be collected in bags enclosing the spikes. Crossing made before 10.00 AM generally sets maximum amount of seed per head.

Crop Specific issuesParental line Seed Production
Sorghum seed multiplication chainIn India, the seed multiplication is in four stage
generation system:• Nucleus seed (NS)• Breeder seed (BS)• Foundation seed (FS)• Certified seed (CS)
The seed certification under law is voluntary as per Seeds Act of 1966 and is applicable to only notified kind of varieties. However, as per Draft Seeds Bill, 2002, only registered kind of varieties that prove DUS and VCU are eligible to be permitted under seed trade and voluntary certification system. Apart from SC, the seed is also sold as truthfully labeled seed (TLC). However the certified seed has the advantage of the seed crop being monitored by an authorized agency to ensure high genetic and physical purity, freedom from disease and pest, high germination and seedling vigor. The seed of different classes is produced based on demand forecasting of annual certified seed requirement depending on seed multiplication ratio, seed
replacement rate and additional seed requirement.
a) Nucleus seedThe handful of initial seed obtained from
selected individual plants of a particular variety produced by the originating breeder or the institute constitutes the nucleus seed. It is not covered under the purview of certification, is produced in small quantities on experiment stations by the breeder under his direct supervision, and forms the basis for further multiplication of breeder, foundation, and certified seed.
b) Breeder seedIt is the progeny of nucleus seed. It bears a
golden yellow tag issued by the producing breeder. Its production is organized by the ICAR through the ICAR institutes, Agricultural Universities and seed corporations in certain crops on the basis of indents received from Department of Agriculture, Ministry of Agriculture, Government of India. Breeder seed production also does not come under the purview of certification. However, production and genetic purity are monitored by the monitoring team consisting of the project coordinator, nominees of

national seed corporation, state seed corporation and state seed certification agency. For the hybrid seed production chain, needs three basic seed lines: male sterile line (A- line), maintainer line (B- line) and restorer line (R- line). The seed of A- line is produced by planting A- and B- lines side by side in isolated. This process will give the A- line seed perpetually. The B- and R- lines can be reproduced easily like any other self pollinated variety. The seed obtained from breeder is normally in small quantities (up to few kilograms). Breeder seed plots should be at least 400 m away from other sorghum field, Johnson grass, and other forage or grassy sorghum types. The seed production estimates for different class of seeds can be calculated by multiplying area and quantity with a factor × 200 as shown in Table 2.
c) Foundation seedIt is the progeny of breeder seed. It is
genetically and physically pure, satisfying the minimum certification standards. Foundation seed is produced by National Seed Corporation, State Seed Corporations, State Farms Corporation of India, State Agricultural Universities and designated public and private sector agencies. The foundation seed shall be the source for production of certified seed. Foundation seed bears white tag on certification. The breeder seed alone should be used to plant the foundation seed plots isolated from other sorghum fields at least by 300 m. Before flowering, grower should search for and destroy all volunteer plants on field borders and ditches, and in nearby fields lying within the isolation distance. Obvious off-types are roughed out before flowering to meet foundation seed standards. The off-types
permitted at the final inspection depend on the seed certification standards and normally genetic purity should exceed 95%.
d) Certified seedIt is the progeny of foundation seed. It should
satisfy the prescribed seed standards. In case of sorghum, Maharashtra State Seed Corporation (MSSC), Andhra Pradesh State Seed Development Corporation (APSSDC) and Karnataka State Seed Corporation (KSSC) are the four major agencies that produce certified seed. Various private seed companies compliment these public sector agencies in sorghum hybrid seed production. Some private companies market both private and public sector hybrids. To produce hybrids, the foundation seed of A- and R- lines are used by certified seed growers. This seed is normally certified by a team of specialists from the State seed certification agency, scientists of research station and state seed corporation. Certified seed bears blue tag. Approved foundation seed alone should be used and planted in large contiguous blocks with an isolation of at least 200 m from other sorghum fields. Rouging can be practiced to remove off-types. The permitted off-types at the final inspection depend on the seed certification standards; normally off-types should not exceed 0.1%. Maintenance breeding
The maintenance breeding is also called as nucleus and breeder seed production, involves the following purification:a) Cytoplasmic male-sterile line (A- line)b) Maintainer line (B- line) c) Restorer line (R- line)

d) Open pollinated variety, a) Nucleus seed production of A- and B- lines
Seed quality with all it ramifications, must be with cardinal virtue in the seed chain. The purity of commercial seed depends on genetic purity of parental lines in nucleus, breeder and foundation seed class. The success, longevity and productivity of the hybrids depend on the maintenance of genetic purity of parental lines. The scheme of nucleus seed production is depicted below.
Season I
Select the individual plants of A- and B- lines from good quality breeder or foundation seed plots grown in large areas (0.25 to 0.50 ha) based on specific distinguishing morphological traits that enable genotype characterization.
1. Raise 200 to 300 rows (each 5 m length) each of A- and B- lines obtained by pooling seeds from selected ear heads.
2. Examine designated morphological traits specially those which are not influenced by genotype × environment interactions such as compactness of ear head from top to bottom and secondary branch distribution, number of whorls, shape of apex, panicle branch distribution at bottom, middle and at apex, glume characteristics (shape, size and color) and awn characteristics.
3. Tag the individual A- and B- plants which are true to type plants. Self the individual tagged plants in B-lines and make the paired crosses between A- and B- at flowering. The ear heads of B-lines and A × B crosses should be labeled properly such as A1 × B1, A2 × B2,…….…A200 × B200. Harvest the individual plants as per labeling. The A-lines should be harvested after B- lines. After proper threshing and drying, store the properly labeled packets. In the laboratory examine the seed of each plant
carefully on the table for uniformity in color, shape and size of seed. Discard the seed from panicles not in conformity (deviating head) from the original
true to type collection used as a seed source. Season II1. Raise plant to progeny rows such as B- line
and A × B crosses from the selected 200 to 300 plants. Retain some portion of seed as remnant seed for all the B line plants and A×B crosses.
2. Observe the individual plants in progeny rows for diagnostic characters. Uproot the rows not confirming to the designated characteristics of the line. The A- lines showing pollen shedders and the corresponding B- lines should also be rejected.
3. Examine for seed morphological characters in laboratory as per the parental line descriptors. Discard the seed of progeny row in case of doubtful deviants, if any.
4. Identify the best progenies (about 50) of A- and B- lines confirming to the designated characters of the parental lines. The remnant seeds of selected best progenies from the original A- and B- plants are identified and bulked separately (of A and B lines), this forms the nucleus seed.
b) Nucleus seed production of R- line
Season I1. Grow a large number of R- line plants.2. At flowering, self about 1000 plants conforming
to the designated morphological characters of the line.
3. Finally select about 200 plants based on field.4. After harvest, rejection is also done based on
deviations in seed color, shape, size, etc.
Season II1. Grow plant from about 200 panicles (row
progeny of the selected plants) in two replications. Retain a portion of selfed produce as remnant seed from Season I.
2. Study progeny rows for the diagnostic characters. The lines not confirming to the characters of the parental line should be rejected. If adequate number of progeny rows confirming to the lines are not found, selfing for
8
Millet Seed Technology
one more generation will be required. 3. It is desirable to test selfed plants of R- lines for
their restoration ability. 4. Evaluate the lines for economic traits and
disease resistance characters as well.5. Identify the best progeny rows (about 50) based
on the diagnostic descriptors of R- line.
Season III1. Grow the bulk seed of remnant seed from
Season I fraction in isolation.2. Ensure adequate pollination during flowering.3. Bulk the seed of all the plants after the harvest.4. This forms the nucleus seed of R- line.
c) Breeder seed production of A- lineBreeder seed of A- line is produced with
the breeder stock seed derived from nucleus seed. Breeder seed field is jointly monitored by a team consisting of producing breeder, project coordinator, and nominees of National Seeds
Corporation, State Seed Corporation and State Seed Certification Agency.
Crop management practices1. The breeder seed field should be clean, fertile,
leveled and with proper irrigation and drainage facilities. Sorghum should not have been grown in the previous year. This is to ensure that no volunteer from previous crop interferes with breeder seed plants. The seed plot should be isolated by 400 m from other sorghum fields. Johnson grass and Sudan grass should be altogether avoided.
2. A planting ratio of 4:2 (A : B) is recommended for better pollen dispersal. The row spacing should be sufficient to permit examination of plants in rows for possible mixture of off-types.
3. The seed rate of 7.5 kg A- line and 5 kg B- line per ha is recommended for A- line seed production.
4. To facilitate rouging operations, a spacing of 60

× 20 cm is most suited. Precautions should be taken to avoid accidental admixing of parental lines.
5. Start rouging before off-types, volunteers or shedders in the female row starts shedding pollen. The sterile types show only the stigma or a few abortive anthers exerted. These should not be mistaken for normal fertile plants. Normal fertile plants show rich yellow anthers, full of pollen in both the lobes. Upon shedding, these lobes rupture at distal end to discharge pollen. The out of place plants, i.e., plants between the rows, male plants in female rows and vice versa should be strictly removed at the earliest opportunity. Special attention should be given at the periphery where the border rows and seed rows meet, since there is chance of admixed seed germinating. In both A- and B- lines, 100% genetic purity should be ensured.
6. Breeder should offer the seed crop for joint inspection by the monitoring team during the crop growth stages approximately after 30-40 days after sowing, during flowering and at maturity (total 3 times).
7. Tapping the male plants or blowing the air over male panicles with empty duster may be done ensure uniform pollen transfer to female panicles.
8. The B- lines should be harvested at appropriate maturity, dried, threshed and stored under proper conditions. During harvesting and processing, the equipment used must be scrupulously cleaned and freed from mechanical mixtures. This standard of cleanliness should be extended during seed packing and transportation also.
9. The seed thus obtained should be properly labeled as A- and B- line seed and stored separately under clean and hygienic conditions.
d) Nucleus seed production of sorghum varieties
Season I1. Grow a large number of plants of a variety
whose seed is being produced.2. Self about 500 plants confirming to the
designated characters of the cultivar at flowering. Finally select about 200 plants based on field observations.
3. After the harvest, rejection may be done based on laboratory examination for deviation in seed color, shape, size, etc.
Season II1. Grow plant to row (5m length) progeny of the
selected plants in two replications. Retain a portion of selfed seed from Season I as remnant seed fraction.
2. Study the progeny rows for the diagnostic characters. The lines not confirming to the designated characters of the variety be rejected. Variation in plants may be with regard to plant height, leaf traits, flowering and maturity period, diseases and pest reaction, and panicle types. If adequate number of progeny rows confirming to the lines are not found, self for one more generation.
3. Evaluate lines for economic and disease resistance traits.
4. Identify the best progeny rows (about 50) based on all the diagnostic descriptors of the variety.
5. These rows should be harvested separately with labels and the seed of individual ear to rows should be cleaned and table-examined kThe deviants, if any, should be discarded.
Season III1. Grow the bulk seed in isolation from remnant
seed fraction (Season I). 2. Ensure adequate pollination during flowering.3. Bulk the seed of all the plants after the harvest.4. This forms the nucleus seed of the variety being
tested.
e) Breeder seed production of B- lineThe breeder seed production of B-line should be
carried out independent of A- line seed production as per seed production norms.
10
Millet Seed Technology
1. Nucleus seed should be the source for the breeder seed production of B- line.
2. General agronomic management practices as described should be adopted.
3. The field and isolation requirements are same as in A-line breeder seed production (400 m).
4. Before flowering, the out-row crosses can be identified with their height and color differences. Rouging should be started before off-types or volunteers start shedding pollen. All rouges and volunteer plants must be cut at the ground level or better still pulled out to prevent re-growth and subsequent contamination and disease and pest dispersal to seed crop. Eliminate other relative contaminants, Johnson grass and Sudan grass existing within the isolation distance.
5. Conduct inspections thrice by monitoring team at vegetative, flowering and maturity stages.
6. Harvesting the crop at physiological maturity (commensurate with black layer formation at the hilar end of seed). Strict hygeine at harvesting, processing, transporting, and storage is a must.
f) Breeder seed production of R- line 1. Breeder seed of R- line is produced from the
bulked nucleus R-line seed source. 2. Seed crop should be isolated by 400 m from all
contaminants.3. Best farming procedures and rouging operations
should be followed. Before flowering, the out crosses can be identified with their height and color differences. Start rouging before off-types and volunteers start shedding pollen. All rouges and volunteer plants must be cut at ground level or preferably pulled out to prevent re-growth or spread of disease and pest to seed crop. Eliminate other sorghum types, Johnson grass and Sudan grass existing within the isolation distance.
4. The R-line seed plots should be well monitored to required standards.
5. After harvest at physiological maturity, the seeds from all plants should be bulked, dried, threshed, packed and stored hygienically.
g) Breeder seed production of sorghum varieties 1. Nucleus seed produced by the breeder through
pure line selection should be used as source of seed for the production of breeder seed.
2. General agronomic management practices as recommended should be followed.
3. Strict isolation distance of 400 m from all contaminants should be adhered to.
4. Best farming procedures and rouging operations

should be followed. The out-crosses reflecting height and color differences should be rouged before off-types start shedding the pollen. All rouges and volunteer plants must be cut from ground level or preferably pulled out to prevent re-growth and
5. subsequent contamination of seed crop with diseases and pests. Eliminate other sorghum types, Johnson grass and Sudan grass existing within the isolation distance.
6. Conduct inspections by monitoring team at vegetative, flowering and maturity stages (thrice).
7. After harvest at physiological maturity, the seeds of all plants should be bulked and maintained.
Sorghum hybrid seed productionThe cytoplasmic-genetic male sterility, induced
by interaction of sterility-inducing factors in the cytoplasm with the genetic factors contained in the nucleus, forms the basis of hybrid seed production. The sorghum hybrids can be developed as follows.
a) Identification of potential hybrid parents (A-, B-, and R- lines)
Potential male and female parents for hybrid seed production are identified by crossing male-fertile plants (inbreds, varieties, germplasm, breeding stocks in advanced generations, etc.) to a male-sterile line (A-line) and evaluating the corresponding hybrids in small plots in an observation nursery. A few plants of each cross are subjected to a bagging test, i.e., covering few panicles with paper bags before anthesis, and observing seed set under the bag after few weeks. A normal bisexual fertile panicle would exhibit nearly 100% seed set whereas in crosses with A-lines, the following three catagories are encountered. 1. Hybrids without seed set (i.e., male-sterility) is
maintained in these hybrids. The corresponding pollen parent is classified as a non-restorer / maintainer or B- line.
2. Hybrids with complete seed set under the bag
(i.e., male fertility) being completely restored in these hybrids. The corresponding pollen parent is classified as a potential male parent / restorer line (R- line) and could be useful in producing hybrids.
3. Hybrids exhibiting partial seed set under the bag. Such hybrids and their male parents are rejected for further studies because experience shows that it is difficult to extract stable R-lines or B-lines from such parents.
The hybrids, with complete seed set under bag are evaluated visually local genotypes as checks. Various agronomic traits such as days to maturity, plant height, fodder yield, grain color, quality, panicle size, hybrid vigor, grain yield, threshability and resistance to diseases and pests are considered. Selected hybrids are advanced for further studies and their corresponding male parents are included in the R- line collection.
b) Hybrid (A x R) seed production (certified seed)
The hybrid seed is produced as certified seed under the vigilance of state seed certification agencies on a very large scale by private agencies, seed farms, experienced growers, and other extension organizations. Sorghum hybrids involve A × R seed production and are carried out according to the prescribed standards of production and processing in terms of isolation distance, genetic purity, and seed quality.
Seed certification and seed law enforcement agencies have an important role to play in certified hybrid seed production and distribution, because the crop performance is dependent on the quality of the certified seed used. Although production of hybrid seed can be carried out by small individual growers, it is convenient to grow it in large compact blocks of 100-150 ha in a single or cluster of adjoining villages to avoid isolation problems. The quantity of certified seed produced depends upon the projected demand for the seed of a particular cultivar; normally an excess of 20% over the
12
Millet Seed Technology
demand is produced. The requirements of isolation distance must be satisfied by a negotiated contract between a contract grower or group of farmers living in a community (seed village) and the seed firm. The seed companies train supervisory staff who will in turn advise and assist the seed growers in hybrid seed production across critical crop growth stages. Close communication between seed growers and the company supervisory staff during the entire hybrid seed production season facilitates quality hybrid seed production.
c) Basics of sorghum hybrid seed production Sorghum hybrid seed production is a highly
commercial venture. It is essential to maintain efficient level of crop management in order to maximize production at minimum cost. The guidelines for hybrid seed production are as follows:
Selection of area and fieldCommercial seed production must be carried
out in a systematic manner. Selection of areas and seasons free from disease and pests is very important before planning a sorghum seed production program. Hybrid seed production agencies have to identify suitable areas for efficient seed production through preliminary experimentation. Areas endemic to serious disease, pest, and obnoxious weed like Sorghum halepense and Striga are not suitable. Areas that are prone to natural disasters such as floods, excessive rains or high humidity during the grain filling stages of sorghum could cause grain molds, discoloration, weathering, and pre-harvest sprouting, all of which affect seed germination and seed quality. Days to 50% flowering of the

hybrid parents, productivity vs. cost, and climatic conditions, particularly during grain-filling stages, should be important considerations to select an area for seed production. If seed production is planned for off-season, access to irrigation facilities is important. Sugary disease (Claviceps sorghi and Claviceps africana) is prevalent in hybrid seed production plots of sorghum where female parent is highly susceptible. The seeds infested with pest and disease will loose their vigor and viability at faster rate in storage and will become unfit for planting within a very short period. As successful disease and insect pest management is one of the most important factors in raising healthy seed production, seed plots of all categories should be raised from seed treated with proper fungicide and insecticide.
SeasonThe seed of commercial hybrids is produced
in dry weather of rabi (hot monsoon) and summer seasons both by public and private sector seed agencies and marketed in summer season itself. However, seed for rabi has to be stored till the next rabi. Consequently, there will be revalidation and storage loss problems. The seed production in rabi is predominantly concentrated in Andhra Pradesh and adjacent part of Karnataka due to favorable agro-ecology. Rabi seed production in Andhra Pradesh has obvious advantages over kharif production due to the following reasons.
1. Seed production under assured irrigation.2. Warm rabi temperature in Andhra Pradesh
and adjoining areas is conducive for better seed growth than cold temperature spells in Maharashtra and other northern states.
3. Crop maturation under clean weather condition ensures high germination, better luster and healthy bold seed.
4. Better feasibility of staggering, manipulation of nicking / synchrony of flowering.
5. Timely harvest and drying in summer months at field and processing.
6. Expeditious supply of seed for kharif sowing
minimizes the storage and quality losses..Determining the hybrid seed quantity targets
The quantities of hybrid seed required should be roughly estimated on an annual basis in advance, depending upon the projected demand for the commercial hybrids under cultivation. It is desirable to maintain significant quantities of carry-over seed as an insurance against unforeseen seed crop losses.

in alternate strips of rows, normally in 4(A):2R ratio, depending on the experience of seed grower, success experienced over years and the ability of the R-line to disperse the pollen. The borders on all four sides of the hybrid seed production field are sown with the restorer (R) line to ensure adequate supply of pollen and as a guard against contaminating stray pollen. The ideal planting ratio between male and female lines is two male rows alternated by 4 to 6 female rows. If the male line has smaller earheads and shorter flowering span than the female line (as in case of CSH 14 and CSH 15R), then it is desirable to allow only four female rows for each pair of male rows. The female rows for each pair of male rows can be increased to six if the male lines have larger panicle and longer span of flowering. A five row thick border all around the seed production plots must always be provided. Economizing on male lines both within the plots and borders may affect the seed set.
Isolation requirement for hybrid seed plot
Minimum isolation of 300 m is generally recommended for hybrid seed production. In case of sorghum, a distance of at least 400 m is necessary if Johnson grass and other forage or other grassy relatives exist in the growing vicinity. Time isolation (staggered sowing of seed plots to avoid overlapping in flowering of the seed crop and the adjacent crop) is not permitted for sorghum seed production excepting experimental stations where seed crop is grown under the supervision of sponsored breeder. In view of large number of
14
Millet Seed Technology
hybrids being released and commercially cultivated, getting required isolations (300 to 400 meters for foundation and 200 to 400 meters for certified seed crops) is increasingly becoming difficult. Therefore, it is necessary that seed production is planned hybrid-wise in few clusters of villages as envisaged under the seed village concept. Each cluster can have 2-3 contiguous villages covering more than 200 ha. The number of clusters may depend on the total seed required based on demand and supply. Compact blocks aid easy supervision, maintenance of quality, minimizing the nicking and isolation problems and will also serve as demonstration blocks. Exploitation of non-traditional areas for sorghum hybrid seed production is another alternative to solve the isolation problems. However careful planning, handling and extension of seed production technology to seed growers are prerequisites to launch of seed programs in non-traditional areas.
Plant heightMost of the sorghum hybrid parental lines have
matching heights in the rabi season facilitating easy pollination process. The problem of height disparity can be avoided to some extent by planting
the short parent on the raised ridges and the taller parent in the furrows below. Selective urea sprays that elongate the peduncle can also aid to increase the plant height to some extent.
Nicking and ensuring synchronizationIt is essential that the parental lines chosen for
hybrid seed production flower at the same time i.e, the viable pollen is available when stigmas are receptive. Therefore, prior knowledge on flowering patterns of both the parents in hybrid seed production is necessary. The male and female parents of the various hybrids, with different degrees of photo-and thermo-sensitivities may react differentially under different daylength and temperatures at various locations, seasons or planting dates. Several methods are employed to ensure synchrony. The commonly followed technique is staggered planting i.e., adjusting the planting dates of the parents so that they flower simultaneously. If the difference in flowering between the two parents is only 2-4 days, it is possible to manipulate it through selective foliar application of 1-2% urea to the late parent at flower primordial initiation stage (between 30-40 days after planting), and is repeated 3-5 times on alternative days depending on need and practical

experience of the farmer. If the flowering differs between the parents, ratooning of the early parent at appropriate time could be followed. In case of non-synchrony, dusting or spraying of pollen collected from the male parent, if available in the vicinity can resorted to. Hybrids with simultaneous nicking of parental lines when sown on the same day are ideal, because a difference of 4-5 days in flowering between two parents could seriously affect seed set on the male-sterile line. If parents differ in their days to 50% flowering by more than 3 days, staggered sowing is recommended. Under rain-fed conditions staggered sowing may be difficult. Preliminary data on flowering behavior of the parents, pollen production efficiency and stigma receptivity aid in successful commercial hybrid seed production in new areas.
Measures for successful synchronization of flowering of male and female parents• The growth stages of male and female parents
should be critically examined at 4-weeks stage or even later depending upon the length of their vegetative growth period.
• The flower primordia and the apex of male and female plants be sampled randomly and observed critically by stripping the leaves of stem. The difference in the time of initiation and size of the panicle bud (primordial) would indicate the difference in their time to 50% flowering.
• The growth and flowering in lagging parent can be hastened by selective measures like supplemental nitrogen application (additional dose of 50kg N/ha) followed by foliar spray of urea spray (1-2%), soaking of seeds in water (seed priming or seed hardening), and GA spray at primordial initiation stage.
• Alternatively, selective irrigation of one parent and delayed irrigation of the other will also help in synchronizing the flowering dates of the parents. Irrigation under cool climate may futher delay flowering.
• Careful manipulation of nitrogenous fertilizer
application, foliar spray of GA and irrigation can synchronize the flowering of parents that differ by up to one week.
• If the male is advanced in the early stage due to adverse seasonal conditions, cut alternate plants to allow the tillers to come up and boost up such tillers with additional dose of nitrogen.
• In case of partial seed setting, sugary disease (ergot) may occur. However, making available pollen to achieve good seed set ensures better control of ergot disease.
Pollen production and dispersalThe pollen production is influenced by
temperatures. During winter, especially in areas where the night temperatures are rather low, pollen production and dispersal is appreciably reduced. In fact the staggered planting of the two male and border rows ensures adequate and prolonged availability of pollen. It is not safe to rely entirely on natural winds to aid in pollen dispersal. It is desirable to use supplementary aids of pollen dispersal like gentle tapping of male plant or blowing air through empty duster over the male heads. It is also advisable to spray 1-2% Borax (Na2B4O5(OH)4·8(H2O) to improve the pollen production and dispersal. If the pollen is not available in the same plot, one may collect the pollen in the morning from neighboring plots (if available) and instantly dust or spray with water on the earheads of the female parent. If dew hampers spread of pollen, blow empty power duster on the male rows to disperse pollen towards female heads or tap the male heads. If male plants are sufficiently taller than females, tapping can be easily carried out using a long bamboo pole or irrigation pipe across the block.
Stigma receptivityGenerally the stigmas are receptive for 4-5
days (MS 2219A, MS 296A and AKMS 14A) after opening. In some lines it is extended beyond that period as in MS 2077A. However, during the hot summer months, the receptivity is lost faster owing to desiccation of stigmas.

Millet Seed Technology
RougingRegular rouging should follow the
commencement of flowering. Apart from off-types, pollen shedders are also a problem in A-lines. Shedders are plants that look similar to the A–line but exhibit fertile anthers and shed pollen. Such plants can only be identified at anthesis and should be uprooted immediately. Shedders can also arise from partial breakdown of sterility in the A-lines due to high temperatures (>37°C). Delay in identifying shedders will result in out-crossing of male-steriles leading to subsequent genetic contamination of the hybrid. Therefore, it is recommended that rouging be carried out in the early morning hours before pollen shedding takes place. The R- line should also be rouged periodically.
Harvest of hybrid seed
All possible precautions against seed contamination should be taken during harvesting of hybrid seed production plots and threshing of panicles from the A- line rows. Usually, the R-line is harvested first. Later the A-line rows are carefully
inspected for off-types and other chance admixtures and then harvested. Hybrid seed yield (on the A- line) depends upon the yield potential of the A- line, percent seed set, and environmental conditions. The R-line seed in hybrid seed plot is generally not permitted to be reused as seed and should be sold as grain. However, if there are no pollen shedders, and no chance of seed contamination.
d) The economics of sorghum hybrid seed production
The hybrid seed production of sorghum is a specialized operation that needs higher level of competence to meet quality requirements unlike commercial grain crop. The economics of sorghum hybrid seed production was worked out. The cost and the net returns of sorghum hybrid seed production provide a scientific basis for fixing compensation to the seed growers. The estimated variable cost and fixed cost of sorghum hybrid seed production respectively amounts to 81% and 19% of the total cost of seed production. About 57% of variable costs are due to the human labor and material inputs. The net benefit: cost ratio works out

authentic source/agency depending on the stage of seed multiplication.Isolation of seed plot
Sorghum is generally a self pollinated crop but cross pollination up to 5-6% may also occur. It varies from 2-10% with genotypes and agro-ecology and selection of field with required isolation depending on class of seed (foundation or certified seed) and the kind of objectionable crops. The pollen of forage sorghum types can pass and spread to a little more distance and hence require more isolation distance (Table 3).
RougingRouging of the seed field is very important for
quality sorghum seed production. The rouging is done at three crop growth stages i) Before flowering ii) During flowering and iii) Before harvest. The specific certification standards are given in Table 4.
Before flowering• Start the rouging operation before off types,
volunteers or shedders in the female rows start shedding pollen.
• All rouges and volunteer plants must be cut at
to 1.8 under normal seed production scenario.
Principles of sorghum seed production and maintenance
a) Genetic purity maintenance The genetically pure seed of a variety is
expected to have all the unique economic and diagnostic characters. If the genetic purity of a variety deteriorates, the unique traits of the variety are lost and its production potential, adaptation and resistance to diseases and pests also decline. In cross pollinated species like sorghum inbred lines and varieties, the deterioration will be much faster due to out crossing. The major factors causing deterioration of varieties or inbreeds leading to the production of seeds with low genetic purity are a) Residual genetic variation, b) Developmental variations, c) Cross pollination due to undesirable pollen d) Mechanical mixtures, e) Damage due to pests and diseases. The other factors that may have influence on genetic purity are f) Plant breeder’s techniques during selection programs and g) Mutations. The following important measures should be followed during sorghum seed production in order to maintain genetic purity.
1) Adequate attention must be given to land
requirements, isolation, rouging, harvesting, drying, sorting and threshing of ears etc., so as to maintain maximum possible genetic purity.
2) Use the proper class of seed source for further multiplication.
3) The best cultural practices should be followed.4) Inspection should be done at all critical growth
stages.5) Mechanical mixtures should be avoided at
sowing, harvesting, threshing, processing and storage.

ground level or pulled out to prevent re-growth and subsequent contamination of seed crop.
• Outcrosses can be identified because of their greater height and should be removed as soon as these are noticeable.
During flowering• Rouging should be done every day to remove
pollen shedders in the seed rows. The sterile types have only the stigma, or a few abortive anthers exerted. These should not be mistaken for normal fertile plants. Normal fertile plants will have rich yellow anthers, which are full of pollen out to the tips of both lobes. On shedding, these lobes rupture on distal and discharge pollen. All plants out of place, ie., plants in between the rows, male plants in female rows and vice-versa should be removed. Special attention should be given at the ends where the border rows and seed rows meet, as male seed may fall in female rows (or female in male rows).
• In addition, to remove off types and volunteers within the fields eliminate other sorghum and other related plants such as Johnson grass, Sudan grass and forage plants. These sources of undesirable pollen must be eliminated before they shed pollen.
Before harvest: The field should also be rouged thoroughly
before harvest and after the seed maturity to the stage when the true plant and seed characters are exhibited.
Harvesting and threshingThe seed crop must be fully mature at harvest.
Harvesting should be done at physiological maturity stage when the black layer formation appears at the point of attachment of seed with the caryopsis. In general the seeds harvested 35 – 45 days after flowering have superior seed quality. The harvested heads should be sorted out to remove diseased or otherwise undesirable heads, and dried
on the threshing floor for a week or so in thin layer before threshing. Doubtful ear heads are rejected. The border rows of seed plots should be avoided to prevent the chance natural contamination. The male rows should be harvested first and kept separately to avoid mechanical mixtures. After this, the female rows should be harvested. Threshing can be done by clean machine threshers at proper seed moisture content (13-14 %). Seed should be dried to 10-12%% moisture content before storage. Care should be taken to avoid mechanical mixtures while threshing.
b) Seed crop management
Production environmentThe fluctuation in temperature especially at
the critical stage of floral development has a vital impact. Short periods of cool night experiencing ≤13° C induce male sterility. This is mainly because of the fact that ascorbic acid localized in plant
Seed fields can however be certified if diseased ear-heads are removed and burnt and the fields show
on re-inspection, infection not more than maximum permissible level. Only one such re-inspection is
permitted.
Note: Seed fields should be thoroughly rouged to remove plants infected by sugary disease / Ergot
(Claviceps spp), so that the prescribed standards are met at seed stage. However the seed fields shall not be rejected on account of presence of sugary / ergot
infected earheads.

parts produce mono-de-hydro ascorbic acid at low temperatures leading to free radical change and formation of charge transfer complex and alteration of photo morpho-genetic process inducing male sterility. Secondly, low temperatures during floral induction restrict the nutrient supply to the developing pollen grain and render them sterile. The problem of pollen shedders with yellow anthers arise at temperatures ≥37- 40°C. The produced fertile yellow anthers of male sterile lines become similar to those of normal maintainer line. It is mainly due to the fact that the high temperature disturbs the peroxidase and cytochrome oxidase enzyme systems during pollen development and breaks male sterility. It has been reported that if the calcium carbonate level in the soil exceeds 300 gram per cubic feet of soil, then the ear head will not produce any seed due to induction of sterility because of lime induced iron stress and ultimate disturbance in the enzyme activity of catalase, peroxidase and cytochrome oxidase during anthesis (Tonapi and Karivaratharaju, 2002). This phenomenon is mainly due to induction of female sterility. Hence in view of these factors there exist lots of limitations that prevent or alter reproductive strategy of sorghum parental lines and hybrids during seed production. Therefore care must be taken to exploit optimum climatic package during crop growth period.
The areas with temperatures during flowering ranging from 25 -32°C are best suited for successful sorghum seed production. Night temperature should not fall below 13°C for longer period since it affects the seed development. Flowering and seed development stages should not coincide with the rains as the pollen loss and grain molds deteriorate seed quality. The fields where sorghum was not grown in the previous season should be selected. In addition there should be no Johnson grass in the seed field or with in isolation distance. The field should be well leveled and drained. The saline, alkaline or very lighter soils are not suitable. Uniform and level piece of land with good drainage should be selected. The pH should be around 5.5 to 8.5. Good irrigation facilities are essential for sorghum seed crop. The land should be free from the residues of previous crop stubbles, weeds etc. The land should be well prepared to a fine tilth by deep ploughing, three to four harrowings followed by leveling for uniform germination and plant stand.
SeasonSorghum seed production is mostly undertaken
during kharif in Maharashtra, Madhya Pradesh, Rajasthan and Gujarat. In the other sorghum growing areas it is taken in rabi or summer season. Seed produced in seasons other than kharif always

Millet Seed Technology
produce seeds with good germination and vigor. During kharif, infections due to grain molds deteriorate the seed quality and marketable value of the seed. The sowings are usually carried out before the end of June and September in kharif and rabi seasons respectively. Early sowing wards off shoot fly attack and seed crop passes through its life cycle at the most optimum environmental regime promoting better nicking and seed development.
Seed treatmentShoot fly can be effectively controlled by
treating the seed with 50% soluble powder of carbofuran @ 100g per kg of sorghum seed.
SowingMaintenance of male sterile line (A- line)
involves sowing of two parents i.e., A- line (male sterile) and B- line (male fertile). Similarly certified seed production of hybrids includes male sterile A- line and fertility restorer R -line. The borders rows (4 - 6) should be sown with male line all round the seed production plot. To facilitate frequent rouging operation, a spacing of 60 cm (row to row) and 15 - 20 cm (plant to plant) is advisable. Precautions should be taken to avoid admixing parental lines at the time of sowing. For A- line seed production the seed rate is 7.5 Kg/ha of A- line and 5 Kg/ha of B- line. The usual planting row ratio of A- & B- lines is 4: 2 for breeder seed production. For certified hybrid seed production, the female and male lines in 4: 2 row ratios can be sown. However, the proportion can be widened to 6: 2. The general seed rate varies from 7-8 kg/hectare depending on spacing and planting ratios.
Fertilizer applicationRecommended dose of fertilizers (80kg N: 40kg
P2O5; 40kg K2O / ha) should be applied to realize optimum yield and good quality seed. Higher fertilizer dose (100kg N: 50kg P2O5: 50kg K2O / ha) enables better expression of plant characters, since seed production is highly technical and high input use activity.
IrrigationCrops for all seed categories of seeds should
be grown under assured source of irrigation. The flower primordial initiation, boot leaf, flowering and grain development are the most critical crop growth stages in sorghum. Moisture stress at any of these stages will result in significant reduction in seed size, yield and quality.
Plant protectionThe successful disease and insect pest
management is one of the most important factor in raising a healthy seed crop. Seed plots of all seed categories should be raised from seeds treated with proper fungicide / insecticide. Rouging of diseased plants should be done promptly. The insecticide and fungicide spray at recommended dose should be made throughout the crop growing season.
Pest control
Shoot flyShoot fly can be controlled by seed treatment
with Carbofuran 50% soluble powder @ 100g/kg seed. It can also be controlled by applying Furadan 3G or Phorate 10G in the seed furrows @ 20kg/ha at the time of sowing.
Stem borerStem borer can be effectively controlled by
application of Endosulfan 4G/4D, or Carbaryl 3G or Malathion 10D or Furadan 3G @8-12kg/ha at 20 and 35 days after seedling emergence.
MidgeHigh levels of midge infestation can be
controlled by spraying endosulfan 35 EC -1 litre, or lindane 20 EC -1.2 litres, or malathion 50 EC -1 litre per hectare in 500-600 litres of water followed by second application 4-6 days later.

dusting of Malathion 10D @ 20kg/ha.
Disease controlGrain molds in kharif and charcoal rot in
rabi are the key diseases. The seed should be treated with Thiram or Captan @ 3g per kg of seed. Grain mold incidence can be minimized with Aureofungin solution @30g /10 lt of water + Captan (30g/10 lt of water) or Dithane M 45 + Captan @3%concentration). Charcoal rot can be reduced by proper soil management practices by conserving soil moisture, besides growing tolerant cultivars. Leaf spot such as rust can become serious in favorable climate during the kharif and rabi seasons, and can be controlled by spraying Dithane M 45@ 3% concentration. Sugary disease in hybrid sorghum seed production plots where female parent become infested, can be managed to certain extent by spraying Dithane M 45 or Dithane Z-78 @2g / lt of water or Bavistin @ 5g / 10 lt of water at flowering stage. For chemical control of honey dew stage of ergot disease, spray Benlate (0.1%) at the stage of 50% flowering. Provision of ample pollen during flowering always reduces the chance of ergot incidence. For Downy mildew control, spraying of Dithane M 45 (0.4%) four times at an interval of one week starting from seventh day after planting has proved to be the best.
Inter-cultureHand weeding after 20 days of sowing is
preferable. Inter-cultivation with blade harrow or cultivator will help to control weeds and conserve moisture. Pre-emergence spraying of Atrazine (atrataf) @ 0.5 kg active ingredient per hectare or propazine 50 % wettable powder @ 1 kg in 1000 lt of water helps to control the weeds.
c) Seed processing Seed processing is an integral part of sorghum
seed production and technology, which encompasses the steps such as drying, cleaning, grading, treating, and bagging. Sorghum seed properly threshed can often be cleaned to the desired purity on the air
screen cleaner alone. However, the gravity separator is commonly used, to remove light materials and improve germination.
Physical purityThe threshed seeds should be physically pure
and should not contain weed seeds, disease and pest infested seed, other crop seed, other cultivar seed, undesirable seed, and damaged seeds. Sorghum seed of different classes should possess the following minimum seed purity standards.Seed drying
Seeds contain varying amounts of moisture at harvest, and if they are to be stored for subsequent planting it is essential that their moisture content is reduced to a safe level. High moisture in seeds deteriorates seed viability and causes mechanical damage during processing. In addition to this, high moisture in seeds provides favorable atmosphere

for pest and disease infestation in storage. Sorghum seeds should be dried to 10-11% moisture content to avoid the breeding and multiplication of insect population in storage. The moisture content fluctuates during storage in cloth or hessian bags, but if the seed store is reasonably moisture vapor proof, the fluctuation in seed moisture content would be small. In sorghum, proper sun drying of earheads is essential to bring down the seed moisture to desirable level to avoid seed deterioration. In sun drying, seeds are normally dried by spreading them on the floor under diffused sunlight or under shade. Frequent stirring of the seeds is required to facilitate rapid and uniform drying. To dry bulk quantities of seeds can be dried in forced air driers. Maximum recommended air temperature for seed drying is 40° C, however in order to reduce the risk of heat damage to the seeds, drying temperatures should be lower than the maximum recommended. If seed moisture is more than 18%, maximum recommended drying temperature is 32° C and if lower than 18%, 40° C is the temperature for drying.
Seed cleaning and gradingIn order to maintain the physical purity to the
required standards seed cleaning is the essential step in processing unit to separate the inert matter, weed
seed, other crop seed, other variety seed, disease and pest infested seed and any other undesirable contaminants. Sorghum seed cleaning and upgrading is mainly based on physical differences in seed volume, test weight and density. The sieve aperture sizes of top and bottom screens of air screen cleaner differ with genotypes. Generally the top screen has holes measuring 12/64” or 4.75mm with round holes and the bottom screen at 9/64”or 3.5mm with round holes. The specific gravity separator helps in upgrading the quality of seeds by rejecting the seed that is inferior in specific gravity. Seed treatment
Seed treatment refers to the application of fungicides, insecticides, or a combination of both to disinfect the seed from seed borne pathogens and to protect from soil borne organisms. Some chemicals offer a systemic protection against diseases. The use of insecticides reduces the damage to seed by insects. Sorghum seed after seed treatment can be protected from systemic pathogens like loose and head smut and non-systemic pathogens like Helminthosporium blight, Fusarium and bacterial blights. Seed treatment also provides protection against storage pests (rice weevil) and shoot fly. The fungicides like Thiram or captan @ 3g/kg and

23
insecticides like Malathion dust (5%) (Premium grade) @ 0.6g per kg seed are recommended for sorghum seed treatment.
Bulk stacking and storage of processed seeds
Packing Processed seed can be packed in cloth bags or
poly lined bags @ 3-4kg / bag, sewed with proper label of particular seed class and should be sealed with lead seal.
d) Seed storage managementStorage under controlled environment
The genetic damage will not show up in the crop grown from that seed in the first generation, but will begin to segregate in the subsequent generations. Therefore, it is very important to store breeder seed and germplasm material carefully so that the loss of viability and genetic damage is minimized. As soon as seed germination falls by 20-30% from the initial seed germination of 90-95%, the seed should be regenerated. Such seeds should be stored under controlled conditions at a particular temperature and relative humidity regime (Table 6).
Breeder and Foundation seed cold storage
Short term storage under ambient conditionSeeds of most of the sorghum species can be
stored under ambient conditions for at least 12-15 months, if seed moisture does not exceed 9-10%. Relative humidity and storage temperature are two important factors that influence seed viability during storage. The relative humidity of 70% and 20° C temperature can be accepted as maximum permissible thresholds of safe storage. But in tropical countries like India, places registering mean temperature of 20° C throughout the year are few. The seed godowns must be rain proof, relatively moisture vapor proof and insect proof. There should be no cracks in wall or on floors. The bags should not be kept directly on the floor, but on wooden pallets and should be at least 50cm away from the walls. An exhaust fan should operate for ventilation when outside temperature is lower than the temperature inside the seed store, the relative humidity of the outside air should also be considered while planning to ventilate the seed stores. The careful ventilation can reduce both storage temperature and seed moisture. Seeds are invariably attacked by different insect pests during storage. To avoid the storage losses and to keep seeds free from insect pests during storage, one must adopt the following preventive and remedial measures.
Tips for better seed storage1. The seed moisture content should be preferably
below 9%. The moisture content fluctuates during storage in cloth and hessian bags, but if seed store is reasonably moisture vapor proof, the fluctuation in seed moisture content would be low.

2. New bags should be used to avoid both insect infestation and mechanical mixture.
3. The storage structure should be thoroughly cleaned and white washed.
4. The storage structure should be disinfected with residual sprays of insecticides such as Malathion 50EC (one part in 100 parts of water) @ 5litres per 100 sq. m.
5. Proper stacking should be followed for arranging seed bags in storage structures.
6. It should be ascertained that the seed is properly treated with disinfectants before keeping the seeds in storage.
7. Different types of seeds such as cereals, pulses, and vegetables should be stored separately to avoid the spread of insect infestation.
Maintenance of seed storage1. The processing units and storage structures
should be clean.2. All sweeps should be kept far away from the
premises of seed godowns so that insects will not breed and reinfest seeds.
3. The inspection of seed lots in storage structures should be carried out every fortnight. Seeds must be thoroughly fumigated at regular intervals.
4. Fumigation can be done with a) Aluminium phosphide, 2 – 3 tablets (3g each) per tonne of material with an exposure period of 5 –7 days or 1 tablet / m3 space. b) Ethylene dibromide (EDB) @ 32g / m3 space with an exposure period of 5 –7 days. c) Ethylene dichloride carbon tetrachloride (3:1) (EDCT) mixture @ 320 – 480 g / m3 space with an exposure period of 24-48 hrs.
5. Of all these fumigants, Aluminium posphide is safest. Its’ repeated application does not impair seed quality. Maximum of 3 fumigations may be given at an interval of 40-50 days.
6. During fumigation and surface sprays, handle the chemicals carefully as they are highly toxic.
7. Seed structures should be aerated and thoroughly cleaned with brush or hard broomsticks to
remove all dead and moribund insects.8. To prevent reinfestation, surface treatment with
Malathion 50EC or Finitrothion 50EC @ 4-5 litres / m2 area or Malathion dust 5% @ 3-4 kg / 100 m2 should be given.
9. Surface treatment of seed godowns and processing units should be carried out at an interval of 2-4 weeks depending upon the severity of pest. Check on reinfestation prevents insect developing resistance to insecticides
Buffer stockIt is necessary to keep a buffer stock of seed to
meet contingencies such as natural calamities and to safeguard against shortfalls in seed production. The quantity of seed to be kept in buffer should not be less than 10% of the projected requirement in the subsequent year in the case of certified seed, 20% in the case of foundation seed, and 50-100% (depending upon the hybrids/varieties) in the case of breeder seed. The quantity of carry-over stocks must be kept at a minimum.
e) Seed quality control
Seed quality in India is legally controlled by the Seed Act, 1966. According to this Act all the seeds of notified varieties/ kinds when sold to farmers must meet the minimum standards of germination and physical purity. The seed should be packed in a suitable container and a label has to be affixed on the container. Information about germination, physical purity, variety, date of test, name of the seed producer has to be given on the label. The germination as given on the label is valid for 8 months and after which it has to be revalidated for a subsequent period of four months after retest. Seed certification is the process designed to secure, maintain and make available high quality seed and propagating material of superior crop plant varieties, so grown and distributed as to ensure desirable standards of genetic identity, physical purity and other quality attributes. Certification is performed in five phases. 1. Verification of land requirements

sample during the processing and bagging 5. Tagging, labeling and sealing to identify the
seed
If the seed test report is satisfactory indicates that the seed meets the minimum standard of germination, purity and seed health, then a given seed lot is approved and tags and certificates are issued by certification agency to the seed producer. Quality control and regulation of supply of quality seed by seed industry is done by the State Department of Agriculture. It is being regulated by a network of notified seed inspectors with specific jurisdictions as prescribed by the State Govt., in accordance with Seed Act, Seed Rules and Seed Control Order. There were considerable gaps in the scope and implementation of Seed Act, 1966 and as such it was felt to improve the act suitably in the form of Draft Seeds Bill, 2002.
Grow-out testTo monitor the genetic purity of the breeder
seed plots, a sample of basic seed lot is drawn. The samples thus collected from different varieties, parental lines and hybrids are grown at one place along with standard sample under constant supervision of sponsored breeder. The plants are compared for designated characters to determine the genetic purity percent, and the seed lot is labeled as per prescribed norms. The main objective is to determine the genetic purity of a given seed lot of a released cultivar and the extent to which the submitted sample conforms to the prescribed standards. The samples for growth-out test are to be drawn simultaneously with the samples for other
quality tests and the standard procedure shall be followed. The size of the submitted sample should be 500 gm.
While raising the desired population, standard and recommended agronomic / cultural practices (e.g., field preparation, size of the plot, row length, distance between rows, distance between plants, irrigation, fertilization, etc.) in respect of individual crops are to be followed both for the unknown sample and its control. The possibility to prove the genuineness of a cultivar by grow-out test is based on hereditary characteristics of the plants. Usually the cultivar differences are more distinct if growth conditions are favorable. Crop should be so grown that the genetical differences express themselves as clearly as possible. In self-fertilizing species the individual of a cultivar may be theoretically identical whereas the individual of a cultivar in cross-fertilizing species may not be genetically similar, but comprise a number of types. Therefore, it is easier to determine the cultivar purity in self-fertilizing species than in cross-fertilizing species where the examination for greater part is based on the mutual comparison between the samples to be tested and the standard sample. Hence, it is essential to sow the various samples of the same cultivar in succession and standard samples are sown at suitable intervals (for example one standard sample for every ten samples to be tested). The size of plots, row length, etc. will differ from crop to crop. However, the specifications for sorghum crop is indicated in Table 7. The Certification Agency may change the specification if considered necessary.
The seed rate may be adjusted depending on the germination percentage of individual samples and the sowing may be done by dibbling. Subsequent

thinning is not recommended. The test crop may be raised along with the control either in the areas recommended for the variety or in off-season nurseries. The authentic control sample from the originating plant breeder / breeding institute is to be maintained by the testing station / agency following standard procedures. A minimum of two hundred plants from control sample will be raised along with the test crop. The following observations are to be made:a) All plants are to be studied keeping in view
the distinguishing characters described for the cultivar both in the test crop as well as the control. Necessary corrections may be incorporated if the control is found to be heterogeneous.
b) Observations are made during full growing period, or for a period specified by originating breeding institute and deviations from the standard sample of the same variety are recorded. At suitable development stage the plots are examined carefully, and plants which are obviously of other cultivar are counted and recorded.The specification for the field plot, row length,
etc. may be determined from the information given. The number of plants required for taking observations is dependent on maximum permissible off types as determined below in Table 8.
The calculation, interpretation and reporting of the results is always in terms of percentage of other cultivars, other species or aberrants found may be calculated up to first place of decimal. The analysts employed for conducting ‘grow-out test’ should possess the basic qualification as identified under Seeds Rules, 1968. While interpreting the result, use of tolerance may be applied (Table 9).

Seed certification, testing and quality control
Seed is a crucial and basic input to increase crop yield per unit area and to improve agricultural economy of a country. In fact, good quality seeds are “seeds of green revolution”. Therefore, it is imperative to understand the mechanism of maintenance of seed quality, means to preserve genetic and physical purity and the procedure by which planting value of a seed could be assessed. Hence, this topic is an effort in the direction to understand mode of seed certification and methods of seed quality control and seed testing that ensure good seed to perform best in favourable environment and better in less favourable areas.
Seed certification and quality control“Seed certification is a legally sanctioned
system for quality control of seed multiplication and production” consisting of measures like:1. An administrative check on origin of seed
source / propagation material;
Millet Seed Technology
27
2. Field inspection;3. Supervision of harvesting, processing, transport
and storage;4. Sample inspection;5. Bulk inspection;6. Control plot testing.
The main objectives and concepts of seed certification are:1. The systematic increase of superior varieties;2. The identification of new varieties and their
rapid increase under appropriate and generally accepted names;
3. Provision of a continuing supply of comparable material by careful maintenance and by adopting “GENERATION SYSTEM” of multiplication involving three stages:a. Breeder seedb. Foundation seed (sometimes, stage I and II)c. Certified seed
Concepts1. Pedigree of al certified seeds should be based
on lineage;2. Integrity of certified seed growers must be
recognized;3. Field inspection must be made by qualified
inspectors;4. Verification trials that establish and maintain
pedigree of stocks must be conducted;5. There should be standards established for purity
and germination;6. The principle of sealing seeds to protect both
grower and purchaser must be approved;7. Species of farm weeds which would be included
within the meaning of noxious weeds must be defined.
Steps involved in seed certification1. Examination of application;2. Inspection of seed fields;3. Rejection of fields;4. Seed sampling;5. Tagging and sealing;
6. Control plot testing;7. Revocation of certificate.
Minimum seed certification standards are necessary for ensuring the quality of seed. For various activities, corresponding factor for which standard is required is as follows. The certification standards in force in India can be categorized into:1. General seed certification standards;2. Specific crop standards.
The important factors responsible for apparent and real deterioration of genetic purity are:1. Developmental variations;2. Mechanical mixtures;3. Mutations;4. Natural out crossing;5. Minor genetic variations;6. Selective influence of diseases and pests;7. The technique of plant breeder.
In order to maintain seed quality, following “Agronomic Principles” should be strictly followed:1. Selection of ideal location; 2. Selection of plot for seed production;3. Proper isolation of seed crop;4. Land preparation;5. Selection of variety;6. Seed source;7. Seed treatment;8. Time of planting;9. Seed rate;10. Method of sowing;11. Depth of sowing;12. Rouging;13. Supplementary pollination;14. Weed control;15. Disease and insect control;

To maintain the standards of purity and quality of seeds that are to be certified the following conditions are enforced by seed certification agencies.1. Only the fields that have not been planted
during the preceding season to other varieties / hybrids of the particular crop should be chosen;
2. Only one variety / hybrid of a particular crop can be grown for seed production on a farm;
3. The field chosen for seed production should be sufficiently isolated from other varieties of the same crop;
4. The field should be free from noxious weeds;5. Off-types should be removed before they set
seed;6. Strict field inspection at crop growing period
(2-3), harvest and processing by certifying agency is must;
7. Seed bags should be treated, sealed and tagged for authentication.
Why seed drying?• Seeds can be safely stored when they have been
dried to a moisture content of 13%.
• Drying helps seeds maintain their ability to germinate and their vigor for a longer period.
• Drying controls mold growth and the activity of other organisms that reduce the quality of stored grain.
• Drying reduces seed discoloration, which lowers the market value of the seed
• Seed drying methods-forced air drying• Seeds can be dried in a batch-type dryer by
forced air heated to 40- 45 °C. • Do not dry the seeds abruptly to 13% moisture
content if the beginning seed moisture is higher than 20%.
• The seed layer in a batch-type dryer should not be more than 45 cm deep.
Cleaning and grading• Remove impurities such as trash, leaves, broken
seeds, sand or grit, etc. • Remove weed seeds or those of other plant
species. • Remove immature, shriveled, unfilled, and
empty spikelets. • Seed can be cleaned manually by winnowing.
Winnowing removes only light, chaffy material.• An air screen machine not only cleans the seed
but separates seed of uniform size from oversize and undersize seeds. The process of separating seeds of uniform size is known as grading.
• Air screen machines are normally too expensive for on-farm ownership. Cleaning and grading are usually done by public or private seed agencies that contract with seed growers for hybrid seed production.

Seed germination testing• Before seeds can be packed and sold as hybrid
seed, they must be tested for germination rate and purity.
• Public seed testing agencies normally do the testing and certification. The germination rate must be at least 85% in order for seed to be certified.
• Before taking your seed for testing, you can do your own germination test at home by following the instructions.
Packing and labeling the seed• Pack your seed in clean, preferably new, jute
bags. • If you store your seeds in used bags, you should
disinfect the bags to protect the seed from insects that could attack the seed during storage.
• Follow these steps to disinfect used bags. 1. Turn the bags inside out and shake them
thoroughly so no seeds of any kind stick to the inside of the bag.
2. Soak the bags for 10 minutes in a 0.15% solution of malathion. (Make the solution by mixing 1 part malathion 50 EC in 300 parts water.)
3. Dry the bags under shade before filling them with seed.
• Do not pack your seed if the moisture content is more than 13%. The seed could spoil during storage.
• Make two labels for each bag - one to place inside the bag and one to attach to the outside.
• Each label should contain the following information:
1. Your name and address. 2. Name of the hybrid. 3. Location of the seed production field. 4. Season.
Seed testing principles and proceduresThe international rules and regulations for seed
testing (1976, 1999), as finalized at the seventeenth International Congress of Seed Testing, Warsaw
(1974), became effective on 1st January, 1977 in the Southern Hemisphere. For the purpose of better understanding, the principles and procedures for testing samples of different crop groups have been discussed under the following sub-heads:1. Sampling;2. Moisture testing (oven method, by moisture
meters);3. Purity analysis;4. Evaluation of seedlings for germination;5. Vigour and viability tests;6. Seed health testing;7. Verification of genetic purity (grow-out test).
SamplingA sample is obtained from a seed lot by taking
small portions at random from different stocks or positions at the time of processing or packaging or from sealed bags in the lot and combining them. The classification of samples drawn at various stages and for laboratory tests is given below:1. Primary sample: A primary sample is a small
portion taken from a lot, at a particular stage, with the purpose of forming a composite sample.
2. Composite sample: A composite sample is formed by combining and mixing all the primary samples taken from a lot and a part of this sample is sent to laboratory for test.
3. Submitted sample: A composite sample is usually large in quantity than what is required for testing and so needs to be reduced in quantity as per requirement. A composite sample, when so reduced in quantity and sent to the testing station, is called a submitted sample.
4. Working sample: The working sample is part taken from the submitted sample in the laboratory, to be subjected to quality tests as described in the rules.
Analysis of purity componentsIn accomplishing the objectives of the ISTA
Rules, the sample is separated into three components:
30
Millet Seed Technology
Percentage of germinationThe percentage of germination reported in a
Seed Analysis Report indicate the proportion by number of seeds which have produced seedlings classified as normal under the conditions and within the specified period.
Normal seedlingsIt is necessary to distinguish the normal
seedlings which are counted for percentage of germination from abnormal seedlings. According to the ISTA Rules, 1976, normal seedlings are those which come under one of the following categories:1. Seedlings which show the capacity for continued
development into normal plants when grown in good quality soil and under favourable conditions of water supply, temperature and light;
2. Seedlings which are found to possess all the essential structures when tested on artificial substrate;
3. Seedlings which show a vigorous and balanced development of its structures except having some slight defects, such as having a damaged primary root or superficially damaged other essential structure, or having only one cotyledon when they are dicotyledonous;
4. Seedlings with all the essential structures intact but in a sate of decay caused by fungi or bacteria. It should, however, be clear that the parent seed is not the source of infection.
Abnormal seedlingsAbnormal seedlings are those which do not
(1) pure seed; (2) inert matter; and (iii) other seeds.
Pure seedPure seed refers to that species which is stated
by the sender to be the dominant in the seed lot. Such seed as immature, undersized, shriveled, diseased, or germinated seeds, unless transformed into fungal sclerotia, smut balls or nematode galls, be regarded as pure seed, provided they can be identified as of that species.
Inter matterInert matter includes such seed like structures
as pieces of broken or damaged seed, empty glumes or any other extraneous matter such as soil, sand, stone, chaff, stems, leaves, pieces of bark, flower, nematode galls, fungal bodies, insect larvae, etc.
Other seedsThis refers to any kind of seed or seed like
structures of any plant species other than that of pure seed. The distinguishable characteristics set out for the pure seed shall also be applicable to other seeds except certain weed seeds which are classified separately.
Evaluation of seedlings for germinationGermination
Germination in a laboratory test refers to the emergence from the seed embryo of those essential structures which, for the kind of seed being tested, indicate its ability to develop into a normal plant under favourable conditions.
Seed germination testing as per International Seed Testing Association (ISTA) guidelines

show the capacity for continued development into normal plants when grown in good quality soil and under favourable conditions of water supply, temperature and light. Seedlings found to be with the following defects when tested on artificial media shall be classified as abnormal (Damaged seedlings; Decayed seedlings; Deformed seedlings; Hard seeds; Fresh un-germinated seeds; Dead seeds).
Kinds of vigour testsDirect tests
These tests simulate pertinent un-favourable field conditions on a laboratory scale. The principle advantage of such tests is that it simultaneously evaluates all the factors affecting seed vigour.
Indirect testsThese tests measure certain physiological
attributes of seeds. These tests have the advantage that the variables can be precisely controlled, allowing reproducibility of results.
Viability testsOnly two methods, the topographical
tetrazolium test and the embryo excision test have been accepted as official methods:
Topographical Tetrazolium of TZ testIn this biochemical test, living cells are
made visible by reduction of an indicator dye. The indicator used in the TZ test is a colourless
tetrazolium salt. Although a number tetrazolium compounds can be used, 2, 3, 4, triphenyl-tetrazoloium chloride is preferred by most workers. The colourless tetrazoloium is reduced in living cells by action of dehydrogenase enzymes to form a red water insoluble formazan product. The red colour makes it possible to distinguish the living parts of the seeds from the colourless dead parts. Treated seeds fall into three groups: 1. Completely stained, viable seeds; 2. Completed unstained, non-viable seeds; and 3. Partially stained seeds.
Varying proportions of necrotic tissues occur in different parts of partially stained seeds. Localization and spread of necrosis in the embryo and / or endosperm, not the intensity of colour, determine whether such seeds are classified as visible or non-viable.
Embryo excision methodBy this method, embryos are excised from the
seeds, in accordance with the methods of flemion (1938) and Heit (1955) and then placed on moist filter paper or blotter discs in Petri dishes. The tests are placed at ordinary room temperature and light intensity; however, the temperature should not exceed 24 degrees centigrade. The embryos should germinate within a few days to two weeks. Viable non-germinated seeds can be easily distinguished from dead seeds after two weeks.

Pearl Millet
Pearl millet (Pennisetum glaucum) is a major warm season coarse grain cereal grown on 26 million ha
in some of the harshest semi-arid tropical environments of Asia and Africa. India has the largest area (9–10 million ha) under this crop, ranking it third along with sorghum. It is cultivated in the most sandy, infertile soils and droughty environments (eg, arid Rajasthan) where no other cereal crop can survive. Even under these conditions, pearl millet yields 300–400 kg ha-1 of grain. Pearl millet hybrids maturing in 80–85 days, when
cultivated as an irrigated summer season crop in parts of Rajasthan, Gujarat and Uttar Pradesh states of India, have been reported to give as high as 4000–5000 kg ha-1 of grain yield. Pearl millet grains have high protein content, balanced amino acid profile, and high levels of iron, zinc, and insoluble dietary fiber. Eggs produced from layers fed on a diet of pearl millet have much lower levels of LDL (the bad cholesterol) than those fed on a maize-based diet. These adaptive and nutritional features combined with high yield potential make pearl millet an important cereal crop that can effectively address the emerging challenges of global warming, water shortages, land degradation and food-related health issues.
OriginPearl millet originated in tropical western
Africa some 4000 years ago. The greatest numbers of both wild and cultivated forms of this species occur in this region. From there, it differentiated into globosum race and moved to the western side, and it also differentiated into the typhoides race that reached eastern Africa and spread to India and southern Africa some 2000–3000 years ago.
India is the largest producer of this crop, both in terms of area (9–10 million ha) and production (7.0–7.5 million t), with an average productivity of 780 kg ha-1 during 2000– 04. As compared to the early 1980s, pearl millet area in India declined by 26% during 2000–04, but production increased by 19% owing to 44% increase in productivity.
AdaptationPearl millet can grow in a wide range of
ecological conditions and yield reasonably well even under unfavorable conditions of drought stress and high temperatures. It is mostly grown in countries with hot and dry weather, quite characteristic of the arid and semi-arid environments. Pearl millet grows on soils that are too sandy and light textured, too arid, too dry and too infertile for other cereals. It played a significant role in food security and preferred by resource poor farmers of dry regions for its better nutritional value.
BotanySeed production procedure in crop species
depends on its mode of pollination which corresponds to its floral biology. The salient
78
Millet Seed Technology
features of floral biology and mode of pollination in pearl millet are given briefly as under:
Pearl millet inflorescence is a compound terminal spike or panicle. It consists of a central rachis. It bears fascicles on rachillae, arranged in a spiral form. Each fascicle contains 1-2 spikelets surrounded by a whorl of bristles (i.e. involucre). A spikelet consists of two glumes and two florets. The lower floret is staminate and the upper hermaphrodite. The ovary is free and exposed and monocarpellary. The styles are free or adnate at base and bifid, terminating in brust-like stigmas. There are three stamens with penicillate and versatile anthers.
Pearl millet is a protogynous species. The styles start protruding two to three days after the emergence of the panicle. The stylar branches protrude first from the florets in the upper middle region of the panicle and then proceed both upwards and downwards. In the hermaphrodite flowers, the stigmas emerge faster than the anthers and hence stigmas receive pollen from infloresence of other plants. The time required for complete stigma emergence varies from 2 to 3 days, depending on the environmental conditions. The two stigmas separate and diverge only after complete exertion of the styles. They remain fresh and receptive for two to three days, depending upon environment. The sequence of flowering practically excludes self-pollination in the same inflorescence, but it may occur between the inflorescences of the same plant.
By the time anther emergence commences, all stigmas will have emerged, and been pollinated, which avoids selfing under open-pollination conditions. The emergence of the first anther usually begins about three to four days after the first stigma has emerged. Protogyny and the time lag between stigma emergence and anther dehiscence favours cross-pollination, but asynchronous flowering of tillers prevents its full realization. The protogyny in the pearl millet is exploited for controlled cross pollination without resorting to emasculation. The inflorescence to be used as a female or male
is covered with the glassine paper bag before any stigma is visible. Generally the safest stage is when about one third of the inflorescence is out of the flag leaf sheath. When all stigmas have emerged, the panicle can be considered ready for cross pollination. If selfed seed of the male parent is not required, pollen from it can be collected by bagging even those inflorescences in which stigmas have completely emerged. Fresh pollen from dehiscing anthers, visible as yellow powder in the transparent selfing bags, is collected by tapping the bagged inflorescence. The pollination is carried out by quickly removing the bag from the female inflorescence, dusting the pollen collected from the male inflorescence, and then rebagging the pollinated inflorescence again.
Crop specific issuesProduction constraints: Cultivation of pearl
millet on marginal lands, and unreliable rainfall tend to keep the use of inputs such as fertilizers to a minimum. Crop losses also occur due to occurrence of downy mildew and bird damage.
Seed productionThe best season for seed production is October
- December. The temperature favourable for seed setting is 37°C. The pollination should not coincide with rains. Rain affects effective seed setting and production of quality seeds.
Crop improvement and varieties released
Open pollinated varieties (OPVs) and hybrids are developed in pearl millet. Seed of open- pollinated varieties may be utilized by farmers for 2-3 years. Hybrids are the result of two specific male (restorer line or R line) and female (male sterile line or A line) parents. Hybrid seed is produced and planted afresh every year.
The commercial end-products in pearl millet are OPVs and hybrids. Once the decision is taken to release a cultivar with specific characteristics and the OPV or hybrid is identified with a name,

pearl millet breeders make a limited increase of seed of new varieties and hybrid parents. Seed
multiplication of any class depends upon the actual requirements and the buffer stock.

Seed classesIn pearl millet, seed is multiplied in four stages
(nucleus, breeder, foundation and certified), called seed classes.
Nucleus seed: It is the first stage in the chain of seed multiplication of a released variety or hybrid parents. This fundamental stock of seed obtained from the selected individual plants of parental lines of a hybrid (A, B, R line) or an open - pollinated variety is the only seed that can be used to produce its own seed class. Nucleus seed should be of the highest genetic purity and the responsibility of it lies with the originating breeder.
Breeder seed: Breeder seed of a released OPV or hybrid parents is produced by or under the direct control of the sponsoring plant breeder. This class of seed is the base of the first and recurring increase of foundation seed and required to be inspected by a monitoring team consisting of a breeder, seed certification officer, representatives of National Seed Corporation (NSC) and State Seed Corporation (SSC).
Foundation seed: Foundation seeds of a released open-pollinated variety or hybrid parents are produced from breeder’s seed, the production of which is carefully supervised or approved by the breeder and seed certification agency at the experimental station or recognized seed farms. It is a source for certified seed class and should satisfy the minimum seed certification standards.
Certified seed: Certified seed of a released open-pollinated variety or hybrid is produced by registered seed producers, duly certified by seed certification agency and produced on a large scale for general farm scale.
Seed production guidelinesA. Nucleus seed productionNucleus seed refers to the seed produced by
breeder who developed the particular variety or by any other breeder of the institution where the variety was developed which is directly used for multiplication as breeder seed.
Nucleus Seed is the first stage in the chain of seed multiplication of a released variety or hybrid parents and is the only seed that can be used to produce its own seed class. To start nucleus seed programme of a variety, seed of base source (seed maintained by breeder) is a prerequisite. It is advisable to produce nucleus seed during off season or under rigorous selfing to ensure genetic purity and homogeneity. The purity should be for all the characters associated with the identity of a variety or line.
The salient features of the procedure for the production of nucleus seed of OPVs, male sterile line, maintainer line and restorer line in pearl millet are described below:
1. Open –pollinated varietySeason I – Isolation Block• Base seed of open pollinated variety is grown
in an area of 0.1 to 0.2 ha maintaining strict isolation of at least 1000 m from any other plot of pearl millet or wild pearl millet. One third of the commercial plant population should be maintained keeping at least 3000 - 5000 plants.
• Carefully observe at critical stages (tillering, preflowering, flowering, dough stage and maturity) and select 500 to 1000 plants with characters identical / typical to the released variety.
86
Millet Seed Technology
• Harvest and keep seed of each selected plant separately. Evaluate for seed characters.
• Keep half of the seed of each plant progeny as remnant seed.
Season II – Progeny evaluation• Plant unreplicated progeny rows along with
check rows (grown from the basic bulk seed of OPV) after every 15-20 rows.
• Compare progeny rows at critical stages and select 30 to 50% progenies confirming to the varietal characters.
• Bulk the remnant seed of selected progenies.
Season III – Nucleus seed nursery• From the bulked remnant seed grow nucleus
seed nursery in isolation (1000 m).• The harvested seed is bulked and can be divided
into five-six lots and kept under cold storage. • One of these lots can be used as base seed for
nucleus seed production when required and rest may be used for breeder seed production in subsequent years.
2. Hybrids: The nucleus seed production of hybrids essentially involves the seed production of their parental lines. In case of pearl millet, especially single cross hybrids are in vogue, thus an account of production of nucleus seed of single cross hybrids i.e. A line (Male Sterile), B line (Maintainer) and R line (Restorer) is given below:
(i) Maintainer line ( ‘B’ lines):Season I• Grow large number of plants of B line (0.05 ha.)
and select and self about 1000 plants at the time of flowering.
• Finally select about 200 selfed plants confirming to the characters of maintainer line.
Season II• Grow plant to row progeny of selfed plants in
two replications retaining remnant seed. • The progeny rows are studied for the diagnostic
characters and rows not confirming to the characteristics of the line are rejected.
• Identify the best progeny rows (25-30%).• Bulk the remnant seed of selected best lines.
Season III• Grow the bulk seed of remnant seed in isolation.• Bulk the seed of all the plants after the harvest.• This forms the nucleus seed bulk of B line.
(ii) MS A line (‘A’ lines): Season IV• Grow A and B lines in alternate rows. Seeds of
B line will be those obtained from rejuvenation as given in the maintenance of B lines.
• Make 200 – 250 paired crosses between A and B plants.
• Care is taken to cross A and B plants confirming to the line standards only.
• Paired crosses among A and B lines should be labeled viz. A1 × B1, A2 × B2 etc. and harvested seed of each pair should be kept separately.
Season V• Grow the pairs, respective A line (crossed seed)
and B line (selfed seed) in alternate rows.• Retain a portion of seed as remnant seed.• Observe critically pairs of A and B lines for all
the characters including height, flowering and typical morphological characters.
• Observe for pollen shedders in A lines. The A line progenies showing pollen shedders and corresponding B lines should also be rejected.
• Identify uniform pairs of A and B lines which confirm to the standards of parental lines.
• Remnant seed of the A lines of the selected pure pairs is bulked. This forms nucleus seed bulk of A line.
(iii) Restorer line ( ‘R’ lines):Season I• Grow large number of plants of R line (0.05
ha.). Self a number of plants (about 1000) confirming to the standards of line at the time

87
of flowering. • Finally select about 200 selfed plants based on
field studies as well as observation in laboratory for seed colour, shape etc.
Season II• Grow plant to row progeny of selfed plants in
two replications. • Retain a portion of selfed seed of each plant as
remnant seed. • The progeny rows are studied for the qualitative
(diagnostic) characters. The lines not confirming to the characteristics of the line are rejected.
• Evaluate the lines for yield and agronomic score for other economic characters.
• Identify the best progeny rows (30 to 50%) based on all characteristics mentioned above. In the progeny row testing if adequate number of progeny rows confirming to the line standards are not obtained, selfing for one or more generations will be required. These selfed plants of R line should also be tested for their restoration ability.
• Bulk the remnant seed of best lines.
Season III• Grow the bulk seed of remnant seed in isolation.• Bulk the seed of all the plants after the harvest.• This forms the nucleus seed bulk of R line.
B. Breeder/ Foundation seed productionBreeder seed is produced from nucleus seed
stock while foundation seed is produced from breeder seed as per detail is given in seed class. The minimum isolation distance is 1000 m for breeder/ foundation seed of A ,B, R lines and OPVs.
1. Male Sterile (A) line and maintainer (B) line• Multiply ‘A’ lines by planting A and B lines in
alternate set usually in the ratio of 4:2. • Plant 4-8 border rows of B line around
production block to insure adequate pollen supplied to A line.
• Careful and strict rouging is a necessity in A and B lines. Rogue out pollen shedders in the A lines, if any.
• Harvest B-line rows immediately after completion of flowering period.
• Carefully harvest the A line rows and bulk the seed.
• Separate breeder seed production plot should be raised under isolation for nucleus seed stock as base material.
• For breeder seed production of B lines raise separate production plot of 0.1 ha area under isolation (1000 m) as bulk planting from nucleus seed stock.
• Follow rouging and other procedures as detailed in nucleus seed production method.
2. Restorer (R) line and OPV• Breeder / foundation seed production of R
lines and OPVs is done by bulk planting under isolation from the nucleus seed stock.
• Seed plots should be 0.1 – 0.2 ha for R lines/OPVs and at least 3000 – 5000 plants should be maintained.
• Crop is observed at following different stages of growth to identify deviants for different characters:
Stage of crop Charaters specifically observed18 Days After Sowing (DAS)
Identify deviants for early vigour
30-35 DAS Identify deviants for tillering, plant height and other traits
Boot leaf stage Identify deviants based on early flowering
50% flowering Identify deviants for late flowering, panicle exertion & panicle type
Maturity stage Identify deviants for seed type and grain Yield
• Identified off type plants should be removed
by uprooting as cutting of plants may lead to ratoon tillers.
• Select 500 – 1000 panicles (depending on the
88
Millet Seed Technology
requirement) from the bulk planting.• Harvest and bulk the seed.• After harvest, the seed be dried, processed and
stored in safe containers.
C. Certified seedCertified seed of OPV and hybrid is produced
in pearl millet. The stipulated isolation distance for certified seed production, both for hybrids and OPVs is 200 m. The pattern of planting and production of OPVs is the same as for the breeder and foundation seed production. Production must be acceptable to seed certifying agency and fulfill all requirements of certification.
Certified seed is generally arranged through contract growers. Some private seed companies also undertake certified seed production programmes. The certified seed of a hybrid is produced by growing male sterile line with a specified restorers line in an isolated field.
Synchronisation of A and R line is crucial for certified hybrid seed production. This can be mainpulated by (1) differential dates of sowing (2) manipulating of water and fertilizer to one of the hybrid parents and (3) removal of extra early tillers in A or R line to synchronise the ability of pollen shedding and stigma receptivity.
Off-type plants in R line and pollen shedders in A line should be roughed out carefully to maintain genetic purity. A satisfactory certified seed production can be achieved if seed village concept is followed.
Field standardsBajra is a highly cross-pollinated crop with
80% of cross-pollination. The crop should be raised in isolation and seeds should be allowed to set by open-pollination. The isolation distance maintained between the varieties is 400 metres for foundation seed and 200 metres for certified seed production.
Seed standardsThe percentage of minimum physical purity of
certified and foundation seeds should be 98% with
a minimum of 80% of germination capacity and 5 - 12% of moisture content. The presence of inert matter should not exceed 2.0%.
Seed agronomy & crop managementIn order to obtain high quality seed with good
physical appearance, uniformity, large grain size and high germination per cent, proper agronomical practices should be adopted.
Land selectionThe selected land should be fertile and free from
volunteer plants. The land should not be cultivated with the same crop in the previous season. If cultivated, it should be of same variety and duly certified by the seed certification agency.
Seed production plots require extra care. The area chosen should be uniform, well levelled, free from diseases inoculum, weeds and cross compatible wild species of pearl millet. Avoid areas where rain occurs during seed development stages. A few rains, or even continuous high humidity during seed ripening period may cause mould development, or even seed germinate on panicles, discolouring them and substantially reducing germination and storage life. The land on which pearl millet crop was grown in the previous season should be avoided to minimize the problems of volunteers.
Land should be well prepared (15-20 cm deep) for seed production plots. It is advisable to plant seed on ridges at a distance of 45 to 60 cm. Planting is done by drilling, dibbling or transplanting. Drilling places the seed at a uniform distance and depth, enabling uniform plant stand. Further, large areas can be quickly planted by using a precession fertilizers-cum-seed drill mounted on a tractor or drawn by bullocks. Dibbling is a common practice where labour is cheap and fields are small. Transplanting is done practically in all the southern states to save valuable seed material. About 0.03 hectare nursery is enough to provide seedlings for one hectare. It reduces the life span of the field crop by 18-21 days. Transplanting also enables easy adjustment of staggered plantings.

Seed selection and sowingSeeds used for seed production should be of
good quality certified seeds from an authentic source. Seeds should be healthy with good germination percentage. Use only graded seeds. Remove theseeds affected with Ergot and Sclerotia to prevent primary infection. Seed rate is 3 kg/acre (8 kg/ha). Add the selected seeds to the salt water (1 kg salt in 10 litres of water) and remove the floating seeds affected by Ergot and Sclerotia.
Wash the seeds in fresh water for 2 – 3 times to remove the salt and shade dry. Selected seeds should be treated with Azospirillum @ 250 gms /3 kg of seeds (600 gms / 8 kg of seeds). Seeds can be sown directly in the main field in ridges and furrows or seedlings can be raised in the nursery and transplanted to the main field.
Nursery preparation and sowingSeeds are sown in the nursery and then the
seedlings are transferred to the main field. Select an area of 7.5 cents for raising nursery for one hectare (3 cents for one acre). Plough the plot thoroughly and add farmyard manure or compost @ 750 kg / 7.5 cents (300 kg / 3 cents) and incorporate it into the soil by ploughing. Seeds are sown in raised bed nursery in lines. Cover the seeds with farmyard manure @ 500 kg / 7.5 cents (200 kg / 3 cents). 20 – 25 days old seedlings are then transplanted to the main field. The spacing between the plants should be 45 x 20 cm.
Main field preparationThe main field is prepared with series ploughing
to make it a fine tilth (Tilth is the physical condition of the soil that is soft, friable and properly aerated) and formed into ridges and furrows. Apply compost or farmyard manure @ 5 tonnes/acre (12.5 tonnes/ha). Seedlings can be transplanted from the nursery or from the directly sown hill. The extra seedlings from each hill should be pulled out at 20 – 25 days after sowing and transplanted.
To ensure optimum plant populations (120,000
plants) in a hectare, with 45 cm between rows and 12 cm between plants, 4 kg seed is required for the multiplication of restorer lines and OPVs while 3 kg of A line and 1 kg of B line or R line are needed for the multiplication of A line or hybrid respectively.
Nutrient managementBefore final ploughing compost or farmyard
manure @ 5 tonnes/acre (12.5 tonnes/ha) should be applied and ploughed into the soil. Instead of this cattle penning can also be practiced. 50 kg neem cake and 500 kg vermicompost per acre (125 kg neem cake and 1250 kg vermicompost per hectare) should be applied as basal manure.
After first weeding at 20 – 25 days after sowing first top dressing should be done using enriched vermicompost (2 kg Azospirillum, 2 kg Phosphobacterium and 2 litres Panchagavya mixed with 250 kg vermicompost and kept covered for a week and then used) @ 250 kg/ acre (600 kg/ha) followed by the second top dressing at 40 – 45 days after sowing using 25 kg neem cake and 250 kg vermicompost per acre (60 kg neem cake and 600 kg vermicompost per hectare). During flower initiation stage 10% tender coconut solution (1 litre tender coconut water + 9 litres of water) should be sprayed.
For rainfed crop, 50 kg pungam cake and 250 kg vermicompost should be applied as basal manure just before sowing. First top dressing should be done at 20 – 25 days after sowing using 250 kg/acre of enriched vermicompost. At 40 – 45 days after sowing apply 25 kg pungam cake and 250 kg vermicompost per acre (60 kg pungam cake and 600 kg vermicompost per hectare) as second top dressing. Spray 10% tender coconut water at the time of flower initiation. All the above mentioned inputs should be applied to the rainfed crop only when the soil is wet.
Manure and fertilizer requirements include 8-10 tons of farmyard manure or compost, 100 kg N, 60
90
Millet Seed Technology
kg P2O5 and 40 kg K2O per hectare. Fertilizer doses may split into two; a basal dose of 40 kg N and all P2O5 and K2O at the time of planting and topdressing of nitrogen in two equal splits at tillering and panicle emergence may be practiced.
IrrigationThe field should be irrigated soon after sowing
and life irrigation is done on the third day of sowing. Irrigation should be done once in 10 days. Irrigation during tillering, milky stage and maturation stage are very critical. Proper irrigation during critical stages increases the seed setting and quality of the seeds.
Water is an essential input to ensure good seed yield. The most critical stages to irrigate pearl millet seed crop are tillering, flowering and seed development. Moisture stress at any of these stages reduces seed yield considerably. Efficient drainage in seed field is also essential as pearl millet is susceptible to water logging particularly in the early stages of crop growth.
Weed managementThe seed production field should be maintained
weed free from the initial stage. The first weeding should be done at 30 – 35 days after sowing. Subsequent weeding can be done depending upon the intensity of the weeds.
Weeds claim major share of soil moisture and nutrients, and reduce yield of seed crop. They may act alternate hosts for various diseases and pests, and also create problems during harvesting and threshing. These may be checked through two inter cultures at an interval of 20 days in the early stage of crop growth or use of herbicides greatly reduces losses due to weed competition.
JerkingJerking is a process of removing the early
formed earheads of the first formed tillers to facilitate uniform flowering in all the tillers. It is done at 20 – 25 days after transplanting or 30 – 40 days after sowing.
RoguingIntensive roguing should be done at three growth
stages like seedling, tillering and seed setting. To maintain genetic purity of the crop, off-types and diseased plants are rogued out periodically based on the colour and waviness of leaves, plant height, shape and size of the earhead and colour of the grains etc. The rogues should be either pulled out as a whole plant or cut off at the base. Plants affected by green ear, ergot and grain smut diseases should be removed and discarded from time to time.
Field inspectionA minimum of three field inspections should be
conducted between pre flowering and harvesting stages by the Seed Certification Officer. First inspection is done before flowering to check isolation, volunteer plants, off-types, downy mildew etc. The second inspection would be made during 50% flowering to determine relevant factors. The final inspection would be made at the maturity stage before harvesting to determine the true nature of the crop and other relevant factors.
Maximum percentage of off-types permitted at the final inspection is 0.050% for foundation seed production and 0.10% for certified seed production.
HarvestingSeeds attain physiological maturation 30 –
35 days after 50% flowering. The physiological maturation can be identified by change in the colour of the seeds from green to straw yellow. A sunken layer also forms at the point of attachment to the panicle. The moisture content of the seeds at this stage is 30 – 35%. Harvesting is done in two pickings since, the maturation of the earheads are not uniform because of the tillering habit of the crop.
Pearl millet should be harvested as early as possible to minimize losses due to birds and bad weather. At moisture levels higher than 25%, the seeds are too soft to withstand the threshing pressure. The ideal moisture content for harvesting
Millet Seed Technology
91
grain pearl millet is below 20%.In a seed crop, harvesting may be influenced
the physical quality of the seed, processing requirements, storability and seedling vigour. If the panicles can be artificially dried and threshed mechanically, then harvesting can safely be done when the seed attained physiological maturity (25% moisture content).
Threshing and processingHarvested earheads should be dried for two to
three days to attain a safe moisture content of 15 - 18% for threshing. Threshing is carried out either manually or mechanically. Normally the dried earheads are threshed by beating with a bamboo stick. Threshed grains are cleaned by winnowing. Threshed and cleaned grains are graded using round perforated metal sieve of 4/64” size OSAW cleaner cum grader.
Drying and storageThe cleaned and graded seeds can be stored
upto 12 months with proper pre-storage treatment.The panicles should be dried to 12% moisture
content. Proper care must be taken in harvesting particularly of hybrids and A/B lines multiplication to avoid mechanical mixture from logged plants. Care must also be taken during threshing operations. Proper handling of all class of seed in post-harvest operations should be of great help not only to maintain seed quantity but also prevent post-harvest losses in seed quality. Threshing of nucleus/breeder seed should be done by small size
seed thresher. These threshers should be thoroughly cleaned. After threshing, seed should be dried and kept in sealed containers.
Crop diseases and pests managementPearl millet is a high cash value seed crop. It
is therefore, essential to control disease and pests which are likely to reduce the seed yield and quality. Cultural control methods like clean cultivation, planting date adjustment, and uprooting of disease affected plants can substantially reduce the damage and minimize seed yield losses. Sometimes, diseases and pests attack may be controlled through chemicals. Pearl millet is affected by pests like shoot fly, root grub and diseases like downy mildew and ergot at different growth stages.
Downy mildew : Ridomil 25 WP ( 1000 ppm ) 20 DAS; Use more than one hybrid/improved variety in the same year or rotate hybrids/improved varieties in alternate years to check the spread of downy mildew.
Shoot fly : Early planting with the onset of monsoon has effectively controlled shoot fly incidence and two dusting of malathion 5% dust @ 25 kg/ha at 10 and 20 DAG or two sprays of neem oil (with 4 gm soap/lit of water) 0.05 % or two sprayings of endosulfan 0.07 % at 10 and 20 DAG

Millet Seed Technology
Finger millet is an annual robust grass, mainly grown as a grain cereal in the semi-arid tropics
and subtropics of the world under rainfed conditions. It is a staple food crop in the drought prone areas in the world, and is considered as an important component of food security. Finger millet grain can be stored for years without storage pests, which makes it a perfect food grain commodity for famine-prone areas. While grains are used for human consumption, the crop residues are excellent source of dry matter for livestock especially in
dry season. Finger millet straw makes good fodder and contains up to 61% total digestible nutrients.
OriginFinger millet is believed to have been
domesticated in the highlands of East Africa about 3000 B.C., and in the same period it was introduced in India; origins for the crop can therefore be linked to Africa and India.
Finger millet was domesticated in the East African highlands. Cultivation of finger millet spread across the eastern and southern African savanna during the expansion of iron working technology, to eventually reach South Africa some 800 years ago. Finger millet reached India 2000–3000 years ago. From India it spread across South-East Asia to China and Japan. In the United States it is grown on a small scale for bird-seed.
AdaptationAmong millet crops, finger millet figures
prominently; it ranks fourth in importance after sorghum, pearl millet and foxtail millet. Finger millet cultivation is more widespread in terms of its geographical adaptation compared to other millets. It has the ability to withstand varied conditions of heat, drought, humidity and tropical weather. It is an important staple in many parts of eastern and southern Africa, as well as in South Asia. The
crop is productive in a wide range of environments and growing conditions, from southern Karnataka state in India to the foothills of the Himalayas in Nepal, and throughout the middle-elevation areas of Eastern and Southern Africa.
BotanyMorphological description
Finger millet is a tufted annual crop, growing to a height of 30–150 cm and maturing in 75–160 days. Leaves are narrow, grass-like and capable of producing many tillers and nodal branches. The panicle consists of a group of digitally arranged spikes often referred to as fingers. The spikelets are made up of 4–10 florets arranged serially on the finger. All florets are perfect flowers with the exception of the terminal ones which may sometimes be infertile. The grain is oblong to round and oval, reddish brown in colour with the grains’ surface finely corrugated. Typically a tropical, rainfed crop, it is one of the best suited for dry farming. Finger millet is very adaptable and thrives at higher elevations than most other tropical cereals.
Flowering and anthesisComplete emergence of inflorescence in finger
Finger Millet
Millet Seed Technology
93
millet required about 10 days and flowering attains 7-8 days. The flower open between 1 to 5 AM and progress from top to bottom in a finger, however, in a spikelet the order is reversed and proceeds from bottom to top and bigger to smaller flower. The stigma is receptive for a very short period after its emergence from the glumes. The period of anthesis being very short, is conducive for self-pollination and cross pollination is very rare.
Crop specific issues
Seed productionThe best season for seed production is
December – January. Pollination should not coincide with rains for quality and effective seed setting. The temperature of 37°c is favourable for seed setting.

Seed agronomy & crop management
Land selectionRagi can be grown in poor to fertile soil. The
crop can tolerate salinity better than any other crops. The selected land should be free from volunteer plants. The land should not be cultivated with same crop in the previous season. Land should be ploughed 2 - 3 times to get fine tilth and levelled.
Crop management
Finger millet: Irrigated1. Raising of nursery (irrigated transplanted crop)
For raising seedlings to plant one ha of main field, select 12.5 cents (500 m2) of nursery area near a water source, where water does not stagnate. Mix 37.5 kg of super phosphate with 500 kg of FYM or compost and spread the mixture evenly on the nursery area. Plough two or three times with a mould board plough or five times with a country plough. Form raised beds by marking units of 6 plots each of size 3 m x 1.5 m. Provide 30 cm space between plots for irrigation. Excavate the soil from the interspace and all around to a depth of 15 cm to form channels and spread the soil removed from the channels on the bed and level.
Pre-treatment of the seeds with fungicides: Seed treatment with Azospirillum may be done @ 3 packets/ha (600 g/ha) and 3 packets (600 g/ha) of Phosphobacteria or 6 packets of Azophos (1200 g/ha). Mix the seeds in a polythene bag to ensure a uniform coating of seeds with Thiram 4 g/ kg or Captan 4 g/kg or Carbendazim 2 g/kg of seeds.
Sowing : Make shallow rills not deeper than one cm on the beds by passing the fingers vertically over them. Broadcast 5 kg of treated seeds evenly on the beds. Cover the seeds by levelling out the hand lightly over the soil. Sprinkle 500 kg of powdered FYM over the beds evenly to cover the seeds which are exposed and compact the surface lightly. Do not sow the seeds deep as germination will be adversely affected.
Irrigation: Adjust the frequency of irrigation according to the soil type. Provide one inlet to each nursery unit. Allow water to enter through the inlet and cover all the channels around the beds. Allow the water in the channels to raise till the raised beds are wet and then cut off water. One irrigation is given on the 3rd day in the case of red soil to soften the hard crust formed on the soil surface and also to facilitate seedlings to emerge out. Do not allow cracks to develop in the nursery bed by properly

adjusting the quantity of irrigation water. 2. Preparation and management of main field
Plough twice with mould board plough or thrice with wooden plough till a good tilth is obtained. Spread 12.5 t/ha of FYM or compost or composted coir pith evenly on the unploughed field and then plough and incorporate in the soil. Apply NPK fertilizers as per soil test recommendation as far as possible. If soil test recommendation is not available, adopt a blanket recommendation of 60 kg N, 30 kg PO5 and 30 kg K2O5 per ha.
Apply half the dose of N and full dose of N and full dose of P2O5 basally before planting. Broadcast the fertilizer mixture over the field before the last ploughing and incorporate into the soil by working
a country plough. Apply 10 packets/ha (2000 g) of azospirillum and 10 packets (2000 g/ha) of Phosphorous solubilizing bacteria or 20 packets of Azophos (4000 g/ha) after mixing with 25 kg of soil and 25 kg FYM before transplanting.
Transplanting: Let water into the bed, level the bed, if it is not levelled. Plant 2 seedlings per hill. Plant the seedlings at a depth of 3 cm. Plant 18 to 20 days old seedlings. Adopt a spacing of 30x10 cm for planting. Adopt 22.5 x 10 cm spacing for direct sowing. Root dipping with Azospirillum prepare slurry with 5 packets (1000 g)/ha of Azospirillum and 5 packets (1000g/ha) of Phosphobacteria or 10 packets of Azophos (2000 g/ha) in 40 litres of water and dip the root portion of the seedlings in the solution for 15-30 minutes and transplant.

all the earheads including the green ones. Cure the grains to obtain maturity by heaping the harvested earheads in shade for one day without drying, so that the humidity and temperature increase and the grains get cured. Dry, thresh and clean the grains by winnowing and store the grains in gunnies.

Threshing: Green earheads if harvested will contaminate the seeds with immature seeds and interfere cleaning, drying and grading. Dry earheads until seed moisture content is 15% and separate manually by threshing with bamboo stick or machine thresher. Threshed seeds should be precleaned before sundrying, seeds must be dried to 12% before grading. Admix one kg of Activated kaolin or Malathion 5% D for every 100 kg of seed. Pack in gunny or polythene lined gunny bags for storage.
Finger millet : Rainfed Average and well distributed rainfall of 450-500
mm is optimum for rainfed ragi. Fallow ploughing is advantageous for moisture conservation. In the month of April or May, one deep ploughing with mould board plough followed by ploughing with wooden plough twice is necessary. Before sowing secondary tillage with cultivator and multiple tooth hoe to prepare smooth seed bed is necessary.
Seed rate and planting: A plant population of 4 – 5 lakhs per ha is optimum for getting higher yields and higher or lower population than the optimum will reduce the yield. Poor germination, often, is the result of inadequate moisture after sowing in low rainfall areas. Under these conditions, the adoption of a simple technique like seed hardening will not only improve germination and subsequent plant stand but also impart early seedling vigour and tolerance to drought.
Seed hardening: Soak seeds in water for 6 hours. Use one litre water for every kg seed for soaking. Drain the water and keep the seeds in wet cloth bag tightly tied for two days. At this stage, the seeds will show initial signs of germination. Remove seeds from the wet cloth bag and dry them in shade on a dry cloth for 2 days. Use the above hardened seeds for sowing.
Line sowing is ideal and seed drills giving spacing of 22.5 – 30 cm between rows should be used. Finger millet seeds are very small (400 seeds/g) and the recommended seed rate of 15-20
kg per hectare will contain about 4 million seeds. Therefore, even when seed drill is used thinning within the row leaving a spacing of 7.5 – 10 cm between plants, must be followed. Sowing by seed-cum-fertilizer drill is advantageous for line sowing besides efficient utilization of applied nutrients.
Manuring and fertilizationFinger millet responds well to fertilizer
application especially to N and P. The recommended doses of fertilizers vary from state to state for rainfed crop. Recommended dose of 40:20:20 kg/ha N:P:K was applied. With judicious application of farmyard manure inorganic fertilizer efficiency is enhanced. Entire P2O5 and K2O are to be applied at sowing, whereas nitrogen is to be applied in two or three split doses depending upon moisture availability. In areas of good rainfall and moisture availability, 50% of recommended nitrogen is to be applied at sowing and the remaining 50% in two equal splits at 25-30 and 40-45 days after sowing. In areas of uncertain rainfall, 50% at sowing and the remaining 50% around 35 days after sowing is recommended.
Bio-fertilizers :Treating seeds with Azospirillum brasilense (N fixing bacterium) and Aspergillus awamori (P solubilizing fungs) @ 25 g/kg seed is beneficial. In case seeds are to be treated with seed dressing chemicals, treat the seeds first with seed dressing chemicals and then with bio-fertilizers at the time of sowing.
Weed control: In line sown crop 2-3 inter-cultivations are necessary. In assured rainfall and irrigated areas spraying 2, 4-D sodium salt @ 0.75 kg.a.i./ha as post-emergent spray around 20-25 days after sowing effectively controls weeds. Isoproturon @ 0.5 a.i/ha as pre-emergence spray is also effective in control of weeds. In broadcast crop two effective hand weedings will minimize weeds as inter cultivations is not possible.
Roguing: Roguing should be done often to remove the offtypes, volunteer plants and diseased plants

Millet Seed Technology
from the seed production field to avoid the genetic contamination. Roguing should be done upto the flowering stage. Maximum percentage of offtype permitted at the final inspection is 0.05% for foundation and 0.10% for certified seed production.
Field inspection: A minimum of two inspections should be done between flowering and maturity stages by the Seed Certification Officer. The first inspection is done at the time of flowering to check the isolation and off-types and the second done during the maturity stage prior to harvest to check the off-types and to estimate the yield.
Harvesting and processing: Harvest is done once the earheads are physiologically mature. Physiologically mature earheads will turn from brown to green colour. Harvesting is done in two pickings since, the maturation of the earheads are not uniform because of the tillering habit of the crop. Second harvesting should be done seven days after the first one. Mature earheads should be harvested and threshed with bamboo sticks. Threshed grains are further cleaned by winnowing.
Drying and storage: The cleaned seeds should be sun dried to attain a safe moisture level of 12%. Care should be taken while drying to avoid mechanical injury to the seeds and contamination. Seeds can be stored upto 13 months under proper storage conditions.
Crop diseases and pests managementFinger millet is affected by pests and diseases
like pink stem borer, aphids, root aphids, earhead caterpillars, blast, brown spot, mottle streak virus etc., at different growth stages.
To control root aphids, mix Dimethoate 3 ml in one litre of water and drench the rhizosphere of the infested and surrounding plants with the insecticidal solution.
For the control of blast disease, choosing resistant variety and treating seeds with carbendazim @ 2 g/kg seed effectively controlled the blast incidence and resulted in higher yield. Spraying of SAAF @ 0.2 % at 50% flowering and one more need based spray after 10 days is also effective in controlling neck and finger blast.
Smut: Since the disease is mainly seed-borne, it can be controlled by treating the seed with organomercurials or steeping the seed for 10 to 30 minutes in 2 per cent copper sulphate solution or 0.5 per cent formalin for about 30 minutes.
Apply VAM culture (Glomus fasciculatum) at 100 g/m2 in the nursery and also treat with Azospirillum and Phosphobacterium as seed treatment, seedling dip and field application to reduce the reniform nematode population in finger millet.
Blast (Finger millet):Mancozeb @2.5g/l water or Tricyclazole@0.6g/l of water

Foxtail millet (Setaria italica) is a well known small millet variety belonging to the family Gramineae.
Foxtail millet is mostly grown mixed with other crops like cotton, castor, pigeon pea, bajra, groundnut and finger millet. It is also grown as a pure crop, particularly in black cotton soils where it is followed by a rabi crop like coriander in favourable seasons or by safflower or horsegram in years of less rainfall.
Foxtail or Italian millet may well have unrealized potential and the Chinese have claimed exceptionally high yields sometimes exceeding 11,000 kg/ha. However, in India the yield of rainfed pure crop varies from 400-800 kg of grain and 1000-2000 kg of straw per ha. Generally cooked like rice or made into porridge, it makes a food which is considered to be very nutritious. The grain must be pounded or otherwise husked before cooking to remove the tightly enclosed glume. Research on forage quality shows foxtail is similar in quality to other C4 annual grasses. It is finer-stemmed and easier to cure than pearl millet or forage sorghum.
OriginFoxtail millet (Setaria italica) is also known as
Italian or German-Hungarian or Siberian millet. Foxtail millet was considered to be domesticated in the highlands of central China. The main production regions of the world include China, parts of India, Afghanistan, Central Asia, Manchuria, Korea, and Georgia. It is also one of the specialty crops in Japan. In Asia it is mainly grown for human consumption. It was recently introduced in the United States for hay or silage. Because of its short growth cycle it is a suitable crop for nomads, and it was probably brought to Europe in this way during the Stone Age, as seeds abound in the Lake Dwellings in Europe.
AdaptationIt is cultivated in both tropical and temperate
regions. The crop can be grown successfully in areas receiving 750 mm of annual rainfall. Foxtail millet is essentially a grain crop of about 100 days duration suited to conditions of low and moderate rainfall
ranging from 500 to 700 mm. It can be grown in higher altitudes (up to 1830 m above MSL) and is an important food grain in the foothills of Himalayas. It is a crop grown almost throughout the year in different parts of the country. Cultivation of foxtail millet in the lower Deccan Plateau including high lands of Andhra Pradesh, Karnataka and Tamil Nadu account for about 90 per cent of the area in the country. In the hilly regions of North India, foxtail millet is sown with other kharif crops and matures in about 2 months, providing food during scarcity periods. In Punjab, Himachal Pradesh and U.P. it is grown from June-July to September-October either as a border or as a mixed crop with several kharif crops.
BotanyGrowth and development of foxtail millet is
well documented. A progressive shortening of the vegetative period occurs with later plantings, and stem elongation is determined by the length of the vegetative period. Stem elongation was hastened by

late sowing and was retarded by early sowing. The transition from vegetative growth into inflorescence takes place very rapidly. In the lower third of the cone of growth, initial humps of secondary axes appear following enlarged growth of the growing point, with the middle and upper parts still undifferentiated. Later, secondary axes differentiate up to the very top into points of growth.
The inflorescence of foxtail millet has a main stalk with shortened side branches bearings spikes and bristles. The first flowers of foxtail millet may open when three fourths of the panicle emerges from the sheath, or as many as five days after full emergence. Flowering proceeds from the top of the head downward in each of the panicle branches. A large head may take 8 to 16 days to compete flowering. A single floret may remain open about 30 min, and about 80 min are required for the complete blooming process, which is hastened by
high temperatures and low humidity.
Crop specific issuesFoxtail millet is grown mainly as a dry land crop
in semi-arid regions receiving an annual rainfall of less than 125mm. The time of planting typically ranges from May through July. The crop cycle depends on the cultivar and on growth conditions; it may range from 60 to 120 days with a productivity ranging from 800 to 900 kg/ha of grain and about 2500 kg/ha of straw. If the crop is grown for hay or silage it should be harvested when in bloom, since the protein concentration at that stage peaks around 12 – 14%.
Seed productionBest season for seed production is June - July
and February – March. The pollination should not coincide with rains for quality and effective seed setting.

minimum of 75% of germination capacity and 12% of moisture content. The presence of inert matter should not exceed 2.0%.
Seed agronomy & crop managementEarly sowing in the monsoon always produces
higher yields than later sowings. The longer duration varieties gave higher fodder yield when sown early.
Land selection: Foxtail millet needs moderately fertile soil for good yield. The selected land should be free from volunteer plants. The land should not be cultivated with same crop in the previous season. Land should be ploughed 2 - 3 times to get a fine tilth and levelled.
Seed selection and sowing: Seeds used for seed production should be of good quality certified
seeds from an authentic source. Seeds should be healthy with required germination percentage. Recommended seed rate is 2 kg/acre (5 kg/ha). Selected seeds should be treated with Azospirillum @ 125 gms/kg of seeds. Treated seeds should be sown with a spacing of 30 x 10 cm at a depth of 3 – 4 cm.
Main field preparation: The main field should be ploughed for 2 – 3 times to make it a fine tilth and formed into ridges and furrows. During final plough apply compost or farmyard manure @ 5 tonnes/acre (12.5 tonnes/ ha) and incorporate into the soil. Seeds can be sown in the ridges at a depth 3 - 4 cm with a spacing of 30 × 10 cm.
104
Millet Seed Technology
Nutrient management: Before final ploughing compost or farmyard manure @ 5 tonnes/acre (12.5 tonnes/ha) should be applied and ploughed into the soil. Instead of this cattle penning can also be practiced. 50 kg neem cake and 500 kg vermicompost per acre (125 kg neem cake and 1250 kg vermicompost per hectare) should be applied as basal manure.
For rainfed crop, apply 50 kg/acre (125 kg/ hectare) of pungam cake and 250 kg/acre (600 kg/hectare) of vermicompost as basal manure just before sowing. After first weeding at 20 – 25 days after sowing top dressing should be done using enriched vermicompost (2 kg Azospirillum, 2 kg Phosphobacterium and 2 litres Panchagavya mixed with 250 kg vermicompost and kept covered for a week and then used) @ 250 kg/acre (600 kg/ha). During flower initiation stage 10% tender coconut solution (1 litre tender coconut water + 9 litres of water) should be sprayed. All the above mentioned inputs should be applied to the rainfed crop only when the soil is wet.
Weed management: The seed production field should be maintained weed free. Weeding can be done with a tyne harrow when the crop is 30 days old. Allow the weeds to dry for 2 - 3 days after hand weeding.
Irrigation: Kharif season crop does not require any irrigation. It is mostly grown as a rainfed crop. However, if the dry spell prevails for longer period, then 1 - 2 irrigations should be given to boost the yield. Summer crop requires 2 - 5 irrigations depending upon soil type and climatic conditions. During heavy rains the excess water from the field should be drained out.
Roguing: Roguing should be done often to remove the off-types, volunteer plants and diseased plants from the seed production field to avoid the genetic contamination. Roguing should be done up to the flowering stage. Maximum percentage of off-types permitted at the final inspection is 0.05% for
foundation and 0.10% for certified seed production.
Field inspection: A minimum of two inspections should be done between flowering and maturity stages by the Seed Certification Officer. The first inspection is done at the time of flowering to check the isolation and off-types and the second inspection is done during the maturity stage prior to harvest to check the off-types and to estimate the yield.
Harvesting and processing: Harvest is done once the earheads are physiologically mature. Normally crop is ready for harvest in 80 - 100 days after sowing. Physiologically mature earheads will start to dry. Plants are either harvested intact with earheads or earheads alone. The earheads are dried before threshing. The earheads are threshed by stone roller or trampling under the feet of bullocks. The threshed grains are further cleaned by winnowing.
Drying and storage: The cleaned seeds should be dried under the sun to attain a safe moisture level of 12%. Care should be taken while drying to avoid mechanical injury to the seeds and contamination. Seeds can be stored upto 13 months under proper storage conditions.
Crop diseases and pests managementFoxtail millet is affected by pests like army
worm, cut worm, leaf scrapping beetle and shoot fly and diseases like blast and rust at different growth stages. Sowing early in July minimized the incidence of blast and rust.
Blast, brown spot and rust: If these diseases appear at the early stages of the crop, spray Mancozeb (0. 2%).
Grain smut : Seed treatment with Carbendazim @ 2 g/ kg seed.
Downy mildew: Seed treatment with Ridomil MZ @ 2 g/litre. Roguing out and destroying the affected plants.
Army worms, Cut worms and Leaf scraping beetles: Need based dust application of Malathion 5 % @ 3.2 – 4.0 kg/ha

Kodo Millet (Varagu) (Paspalum scrobiculatum) is a well known minor millet belonging to the family
Gramineae. This coarse millet is highly resistant to drought and can also be cultivated in the areas with 400 - 500 mm annual rainfall. It is grown in gravelly and stony upland poor soils to loamy soils. But its cultivation in very fertile soils can boost its production and productivity to a great extent.
OriginKodo millet is a native of India and is in
cultivation since time immemorial. Greater diversity of Paspalum species in the Hindustan centre. The crop was domesticated in southern Rajasthan and Maharashtra some 3000 years ago. The crop is known to be spread throughout the tropical regions of the world.
AdaptationKodo millet (Paspalum scrobiculatum) is grown
throughout Asia and Africa, but is only cultivated as a minor grain crop in India, where it is of great importance in the Deccan Plateau. Its cultivation as grain crop in India is generally confined to Gujarat, Karnataka, and parts of Tamil Nadu. In other parts of the world it is grown as a forage crop.
BotanyKodo millet is an annual herb with adventitious
root arises from lower nodes with numerous thin roots. Branched roots spread laterally and profusely, remain functional throughout the life. Stem is erect, rarely ascending with 60-90 cm height, tufted on a very short rhizome. Glabrous stem with swollen nodes and fully sheathed internodes. Nodal bands become purple at later stage. First node is hairy and the other nodes are glabrous with solid internodes.
The length of internodes increases gradually from bottom to top in any tillers. The number of tillers varies from 5 to 18 according to genotypes.
The Leaf is simple, alternate, bifarious, erect or sub-erect, finely acuminate, glabrous or sometimes soft hairy. Sheaths long, compressed, loose, the mouth hairy with very short membranous ligule.
Inflorescence is a spike or spike like racemes. Each spikelet consists of 1 or 2 flowers and bears at the base bracts or glumes, one placed a little above and opposite the other. These two are empty while a third one called lemma is flowering i.e. it enclosed a flower in its axil. Opposite the flowering glume or Lemma, there is somewhat smaller, two nerved glumes called Palea. Spikes 2-6, sessile usually distant and spreading, rachis herbaceous, broad with ciliate margins. Spikelets usually 2 ranked, 2-3 mm diameter, sessile or shortly pedicilate, broadly elliptic or suborbicular imbricate.
Androecium: Stamens 3, filamentous, anthers 3, 2 locules, open by longitudinal sutures, versatile and pendulous. Gynoecium: Monocarpellary, ovary superior, one cell with one ovule, stigma 2, feathery, style distinct. Grain: Utricle type in which pericarp is like a sac usually attached to endosperm at only one point. Grains are rotundate-elliptic, convex in front, flat on back of palea, scutellum up to half the length of the grain.

Millet Seed Technology
Flowering behaviourFlowers of kodo millet are cleistogamous in
nature and thus remained closed. Protogynous flowers occurs rarely in few genotypes. The opening of the flowers occurs between 7.30 to 8.00 AM in Nagpur conditions. Only 5% flowers open and remaining being cleistogamous. The glumes begin to open at 2.30 AM. The anthers become visible through opening at 2.40 AM, emerge at 3.15 AM and comes completely out at 3.30 AM. Anthers dehisce at 3.35 AM and glumes close completely at 3.45 AM. The dehiscence of anther occurs by a slit at one end and speed up gradually. Mostly the dehiscence of anther begins from the middle and proceed to both ends. The feathery stigma dry up in the evening. The anthers remains fresh and do not wither till next morning. The lodicules are fleshy and do not shrink immediately after the anthesis of flowers. They remain fleshy for 6 to 8 hour after opening the glume and then dried up. The grains mature in 30¬40 days after flowering and remain tightly enclosed by the hardened fourth glume and its palea and have various shades of brown colour.
The best time of anthesis is between 5.45 and 7.30 AM. In this period a single floret of panicle is
open for 20 to 30 minutes. The stigma comes first during anthesis of flowers and anthers arise just after the emergence of stigma.
Crop specific issuesKodo is an annual tufted grass that grows to
90 cm high. Some forms have been reported to be poisonous to humans and animals, possibly because of a fungus infecting the grain. The grain is enclosed in hard, corneous, persistent husks that are difficult to remove. The grain may vary in color from light red to dark grey. Compared to other small millets, it has a long-crop cycle, ranging from 105 to 120 days.
Kodo millet is one of the hardiest among the small millets and grows well in shallow as well as deep soils; it is also adopted to water logged soils. The seeds can remain dormant and be stored for many years. It can produce grain yields of 850 kg/ha without fertilizer and up to 1600 kg/ha with application of N and P.
Seed productionSeed production can be done in June – July and
February – March. The pollination should not coincide with rains for quality and effective seed setting.

All the above mentioned inputs should be applied to the rainfed crop only when the soil is wet.
Weed management: The seed production field should be maintained weed free from the initial stage. It is essential to control the weeds in the initial stages of plant growth especially upto 35 – 40 days after sowing. Generally two weedings at an interval of 15 days is sufficient. Weeding can be done with hand hoe or wheel hoe in line sown crop.
Irrigation: Kharif season crop does not require any irrigation, it is mostly grown as a rainfed crop. In the absence of rains one or two irrigation can be done. During heavy rains the excess water from the field should be drained out.

Harvesting and processing: Harvest is done once the earheads are physiologically mature. Normally crop is ready for harvest in 100 days. Physiologically mature earheads will turn from brown to green colour. Plants are cut close to the ground level, bundled and stacked for a week before threshing. The earheads are threshed by trampling under the feet of bullocks. The threshed grains are further cleaned by winnowing.
Drying and storage: The cleaned seeds should be sun dried to attain a safe moisture level of 12%. Care should be taken while drying to avoid mechanical injury to the seeds and contamination. Seeds can be stored upto 13 months under proper storage conditions.
Crop diseases and pests managementHead smut disease is known to be prevalent
during some years which is seed borne. Steeping the seeds in 1.5 per cent copper sulphate or dusting with copper carbonate at 6 g/kg of seed are equally effective. Organomercurial dusts for seed treatment also control the disease. Bavistin 25 SD [carbendazim], Dithane M45 [mancozeb] and Parasan [phenylmercury acetate] at 2 g/kg seed also give best disease control.
Shootfly: Soil application of phorate 1 kg a. i/ha in furrow is effective in checking shootfly infestation.

Little millet (Panicum sumatrense) belongs to the family Gramineae. It is grown throughout India with
major areas in the states of Karnataka, Andhra Pradesh, Tamil Nadu, Orissa, Bihar, Maharashtra and Madhya Pradesh. Little millet can thrive well upto an elevation of 2100 metres in tropics and subtropics and is photo-insensitive. Little millet originated in Southeast Asia and is nowadays grown throughout India, particularly in Madhya Pradesh, Orissa, Jharkhand and Uttar Pradesh. It is cultivated to a limited extent up to altitudes of 2100
m. The dehusked grain is cooked like rice and eaten. In parts of South India, the grain is processed very similar to the parboiling of rice. Often, roti and porridge are made and consumed. It is also made into flour, used for making puddings or cakes. Another method is to cook cracked grains with vegetables and spices to prepare a food similar to curried rice. Fortification with lysine and heat processing improves protein quality and nutrition. In many tribal areas, little millet is considered as a cash crop as it fetches much higher prices than rice. The straw is thin, soft and cattle consume it readily.
OriginThe origin of this crop is not well documented
except for the probable Indian origin since it is endemic to India and has a name in all vernacular languages of India. Panicum miliare or little millet is cultivated or naturalized throughout India and Sri Lanka, and cultivated in neighbouring countries. The distribution of the crop is limited to India and little diversity is found elsewhere. The luxuriant presence of Panicum psilopodium Trin., a wild relative of little millet in India, is suggestive of Indian origin.
AdaptationThe crop can grow well in drought conditions
and considered as a good famine food as it can produce some grain even under severe drought conditions when all the other crops fail to produce. It is a typical dryland crop suitable for the areas with low rainfall and poor soils.
Little millet is able to thrive on marginal soils
which otherwise yield nothing, and mature as a crop even during famine years. It is a. hardy crop which ran withstand drought better than most of the other cereal crops and also water-logging to a certain degree. If the crop fails, the farmer stands to lose very little as the cost of production as well as the land value is negligible.

45 cm. long; Spikelet- glabrous, rather flattened, suddenly cuspidate, 3-4.5mm, long, mostly paired on unequal pedicels, but often solitary at the end of the branchlets, lanceolate in flower, elliptic or broadly elliptic in fruit. Glume I- very broadly ovate, subtruncate, then suddenly acute, or scarcely acute, about 1/3 the spikelet, white, membranous, 3-5 nerved, nerves arching and anastomising. Glume II - herbaceous, ovate, lanceolate, 11-13 nerved, almost as long as the spikelet. Glume III- herbaceous, broadly ovate, 9 nerved, slightly shorter than glume II, palea as long as the glume (3-4 mm.) flower neuter or rarely with 3 stamens. Glume IV- narrow elliptic, or elliptic oblong to broadly ovate, acute, shining white or pale brown or dark brown, often 3-5 streaked dorsally; Fruit- caryopsis enclosed tightly within the fourth glume and its palea (2.5 to 3.5 mm).
Anthesis and Pollination: The hermophrodite flowers which open in basipetallic pattern have brief and rapid anthesis period. The glumes open for not more than 2-3 minutes, and self-pollination is a rule. There is hardly any natural cross pollination.
Under Indian conditions, the flowers open between 9 AM and 12 noon. Emasculation and artificial pollination is difficult in view of small flower size but not impossible. Encouraging results have been obtained by the contact method of crossing.
Crop specific issuesLittle millet is often planted with the onset of
monsoon and it is the first crop to be harvested in the season. As a result, they provide precious grain in the lean months. Often these crops are associated with tribal agriculture and has been the preferred crop for extreme soil and climatic conditions because of assured harvests they ensure.
Little millet is raised as a pure crop or as a
subsidiary crop mixed with other millets like finger millet in Karnataka, or pulses like horsegram, or bengalgram in Tamil Nadu, Orissa and Bihar or with oilseeds like gingelly, soyabean in Madhya Pradesh. Shifting cultivation of little millet was prevalent in many hilly parts of India till few decades ago.
Crop rotation is not feasible since the holding size is small besides soils are poor in nutrients and moisture. In some places it is included in a two year rotation with horsegram. Little millet - Niger or little millet - mustard crop sequences are popular in Bihar, Orissa and Madhya Pradesh.
On an average, little millet yields 600to 800 kg per hectare. With improved production practices the yield levels could be pushed to 1200-1500 kg per hectare. The husk forms about 20 per cent of the weight of the grain.
Little millet grains can be consumed by direct cooking; they can be made into flour and baked to make bread. Both the plants and the straw are often used as forage. The crop can be grown in a wide range of climates and generally thrives well in poor soils and under adverse climatic conditions. The crop cycle ranges from 2.5 to 5 months. Yield ranges from 200 to 600 kg/ha.
Seed productionSeed production can be done during June –
July and February – March. The pollination should not coincide with rains for quality and effective seed setting.
Field standardsLittle millet is a self-pollinated crop and
should be raised in isolation. The isolation distance maintained between the varieties is 3 metres for both foundation and certified seed production to maintain the varietal purity.

Land selectionLittle millet can be cultivated in both rich and
poor soils. Well drained loam or sandy loam soils rich in organic matter are ideal for cultivation. The selected land should be free from volunteer plants. The land should not be cultivated with same crop in the previous season.
Seed selection and sowingSeeds used for seed production should be of
good quality certified seeds from an authentic source. Seeds should be healthy with required germination percentage. Recommended seed rate is 4 kg/acre (10 kg/ha).
Selected seeds should be treated with Azospirillum @ 60 gms/kg of seeds. Treated seeds should be sown with a spacing of 30 x 10 cm. Seeds should be sown in June – July at the onset of

monsoon rains. Summer crop should be sown in the month of February – March. Seeds are broadcast manually or by seed driller in furrows at a depth of 3 – 4 cm.
Main field preparationThe main field should be harrowed for 2 – 3
times to make it a fine tilth and levelled. The levelled field is formed into ridges and furrows. During final plough apply compost or farmyard manure @ 5 tonnes/acre (12.5 tonnes/ha) and incorporate into the soil. Seeds can be sown in the ridges at a depth 3 - 4 cm with a spacing of 30 × 10 cm.
Nutrient managementBefore final ploughing compost or farmyard
manure @ 5 tonnes/acre (12.5 tonnes/ha) should be applied and ploughed into the soil. Instead of this

cattle penning can also be practiced. 50 kg neem cake and 500 kg vermicompost per acre (125 kg neem cake and 1250 kg vermicompost per hectare) should be applied as basal manure. For rainfed crop, apply 50 kg/acre (125 kg/ hectare) of pungam cake and 250 kg/acre (600 kg/hectare) of vermicompost as basal manure just before sowing. After first weeding at 20 – 25 days after sowing top dressing should be done using enriched vermicompost (2 kg Azospirillum, 2 kg Phosphobacterium and 2 litres Panchagavya mixed with 250 kg vermicompost and kept covered for a week and then used) @ 250 kg/acre (600 kg/ha). During flower initiation stage 10% tender coconut solution (1 litre tender coconut water + 9 litres of water) should be sprayed. All the above mentioned inputs should be applied to the rainfed crop only when the soil is wet.
Weed management: The seed production field should be maintained weed free at least upto 35 days after sowing for retaining the soil moisture and nutrients. Subsequent weeding should be done at an interval of 15 – 20 days. Weeding can be done with handhoe or wheel hoe.
Irrigation: Kharif season crop does not require any irrigation. However, if the dry spell prevails for longer period at least one irrigation should be given at the tillering stage to boost the yield. First irrigation should be given 25 - 30 days after sowing followed by the second one at 40 – 45 days after sowing. Summer crop requires 2 - 4 irrigations depending upon soil type and climatic conditions. During heavy rains the excess water from the field should be drained out.
RoguingRoguing should be done often to remove the
offtypes, volunteer plants and diseased plants from the seed production field to avoid the genetic
contamination. Roguing should be done upto the flowering stage. Maximum percentage of offtypes permitted at the final inspection is 0.05% for foundation and 0.10% for certified seed production.
Field inspectionA minimum of two inspections should be done
between flowering and maturity stages by the Seed Certification Officer. The first inspection is done at the time of flowering to check the isolation and off-types and the second inspection is done during the maturity stage prior to harvest to check the off-types and to estimate the yield.
Harvesting and processingHarvest is done once the earheads are
physiologically mature. Normally crop is ready for harvest in 80 - 85 days after sowing. The crop should be harvested when two thirds of the seeds are ripe. The harvested earheads are threshed by hand or trampling under the feet of bullocks. The threshed grains are further cleaned by winnowing.
Drying and storageThe cleaned seeds should be sun dried to attain
a safe moisture level of 12%. Seeds can be stored upto 13 months under proper storage conditions.
Crop diseases and pests managementThere are no major problems of disease and
pest incidence in little millet. However, the shootfly incidence is severe in some years which could be controlled by applying carbafuron, preferably alongwith azotobacter bio-fertilizer. Soil application of phorate 1 kg a. i/ha in furrow is also effective in checking shootfly infestation.
Rust, caused by Uromyces linearis is reported from India, Sri Lanka and Philippines Islands and it is a minor disease.
