Contributions

Early planting upto3rd week of July, recorded highest yields of Kharif paddy. Among varieties, Swarna, Chaitanya recorded satisfactory yields even plantedlate in August.

In permanent plot experiment on INM (Integrated Nutrient Management)system in cereal based cropping sequence showed that 50% and 25%recommended NPK substituting through Sesbania green leaf manure (or)through compost produced similar grain yields as that of 100% NPK throughchemical form.

In direct sown wet seeded rice, weeds were controlled effectively by use of riceguard (ethoxysulfuron) @ 0.012 kg/ha + Anilophos @ 0.312 kg/ha) andPyrazosulfuron (0.075 kg/ha) with increased grain yield.



In site specific nutrient management, highest rice yield (5.67 t/ha) wasrecorded with application of NPKB (100 – 60 – 90- 5 kg/ha) in Kharif (100 –90-90- 5 kg/ha) in rabi. In both the seasons skipping of P & k reduced the yieldsremarkably.

Rice – Rice – Sunhemp cropping system has given maximum system productivityand profitability followed by rice – rice – pillipesara in different rice basedcropping system for Godavari delta.

Sesbania seed rate of 50 kg/ha and cutting Sesbania at 60 DAS is found to beoptimum better green mass production and to obtain higher rice yields.

In transplanted rice application of Bensulfuron @ 0.06 kg/ha at 3 DAT orTrisulfuron methyl @ 0.009 kg/ha @ 12DAT effectively controlled all types ofweeds and proved to be on par with hand weeding twice.Intermediate deep water rice situation crop fertilized with recommended levelof N, K & Zn all as basal at the time of transplanting gave significantly higheryield over split application of N, K & Zn

Transplanting in lines and weedicide application gave higher yields followed bybroadcasting rice seed @ 80 kg/ha with need based weed control

In rice fallow summer pulse situation, blackgram performed superiorly overgreengram. LBG 623 recorded higher seed yield followed by LBG 20 & T9

Application of starter dose of Nitrogen at Juvenile growth stage by spraying of2% urea at preflowering and 5% DAP at pod filling stage proved beneficial inincreasing rice fallow pulse yield

Research highlights

Zinc deficiency is very severe and wide spread during rabi season andsignificantly response to addition of zinc was observed in rabi season. If zincdeficiency is observed in standing crop, spraying of 0.2% zinc sulphate solutionwas found to be effective for correcting the deficiency.

A dose of 40 kg P2O5 /ha was found necessary for kharif rice while 60 kg/ha for rabi rice in alluvial soils of Godavari delta analyzing for low to medium available phosphorus

The phosphorus present in rock phosphate in neutral to alkaline soils and alsonative fixed `P’ in the soil was found to be effectively solubilised by applicationof phosphorus biofertilizer at 2.5 kg/ha.

Studies on the effect of phosphorus bio-fertilizer on P availability to low landrice conducted at APRRI revealed that Phosphorus bio-fertilizer @ 2.5 kg/ha)was found to be effective in dissolving and making available the phosphoruspresent in rock phosphate @ 60 kg/ha to the rice crop, which is otherwise notreadily available in neutral to alkaline soils, besides improving the soil availableP fertility

Three years (1994-97) studies on fertilizer management for low land rice inpest and diseases endemic areas revealed that substitution of 50% N throughNeem cake and Potassium application in equal splits i.e., at basal and at PI



Neem cake and Potassium application in equal splits i.e., at basal and at PIstage significantly increase the grain yield and straw yields and reduced thepest and diseases incandescence in both kharif and rabi seasons.

Studies on monitoring soil fertility of low land rice soils of Godavary deltarevealed that in East Godavari district 80% of soils are neutral in reaction (6.5to 7.5). The soils are non-saline and nearly 80% of the samples have less than5% free CaCo3. The organic carbon content was medium to high. Theavailable P2O5 status was medium (66%) to high (18%) and available K2O washigh in most of the samples (93%). Whereas in West Godavari district the soilswere mostly slightly acidic to neutral reaction, non saline with very low or evenabsence of free CaCO3 and the organic carbon ranges from high (93%) tomedium (5%). The available P2O5 content ranges from low (51%) to medium(40%). Available K2O content was high in 94% of the samples.

Long term soil fertility management studies are initiated during kharif 1989 as apart of AICRIP programme and are being conducted in both kharif and rabiseasons to date in the same plots to study the influence of different fertilizermanagement practices and conjunctive use of organic and inorganic materialson soil fertility and crop productivity under rice-rice cropping system in Godavarialluvial soils.

The results revealed the application of 100% recommended dose of NPK throughfertilizer along with 5t/ha of FYM gave significantly higher yields over reduction ofrecommended dose of NPK by 50% warranting the need for optimum and balancedfertilization. Substitution of 25 to 50% N through organics like FYM and green leafmanuring produced yields on par with 100% recommended dose of NPK appliedthrough fertilizers after six seasons of experimentation.

After 16 years experimentation also the application of 100% recommendeddose of NPK through fertilizers along with 5t/ha of FYM was on par with substitutionof 25 to 50% N through organics. However the yields were significantly lower when Pand K are limiting. Continuous application of organics season after season resulted insignificantly superior build up of soils fertility in terms of organic carbon, availablenitrogen, phosphorus and potassium over 100% NPK through fertilizers highlightingthe importance integrated nutrient management for sustaining soil fertility andthereby the crop productivity and rice-rice cropping system.

Another important finding is that exclusion of sulphur from the fertilizer schedule for the last 16 years in these heavy fertile Godavari alluvial soilshas not affected either the grain yield or available Sulphur content in soils possiblydue to recycling of substantial crop residues through stubbles fertility value ofsediment deposited by Godavari water during season due to heavy texture of thesoils.

I. Studies on monitoring soil fertility of low land rice soils of Agriculture ResearchStation, Maruteru under delta revealed that 96% or neutral (6.5 to7.5). Thesoils are non saline in 28%,65% saline and 7% injurious to crop growth. Theorganic carbon content was medium (4%) to high (96%) the available N waslow, and P content ranged from medium (4%) to high in (96%). Available Kcontent to high (94%) medium (6%).

II. Studies on the utility of paddy straw as source of plant nutrients to riceconducted for 9 years consequently revealed that application of 2t paddy straw+ 100 kg N and 4t paddy straw + 80 kg N/ha were on par with 120 kg N/ha forrabi rice and resulting in a saving of 20 and 40 kg N/ha with two levels of paddystraw respectively. The residual effect of paddy straw on the succeeding kharifrice was more effective with 4t/ha paddy straw treatment. Hence forsustaining soil fertility in the long-run incorporation of paddy straw @4t/haalong with 80 kg N/ha was optimum.

III. Rice cultivation without N,P and K fertilization continuously for two seasonscaused a considerable depletion of available nitrogen (329 kg N/ha to 293kgN/ha) in alluvial soils of Godavari delta analyzing for medium available N andP2O5 (29 kg P2O5/ha) and high K2O (508 kg K2O/ha) contents. Addition ofphosphorus to soils resulted in the to the build up available P2O5. Grain yieldwas positively influenced by nitrogen application

I. Studies on the source and method of application of phosphorus revealed thatphosphorus application produced significantly higher grain and straw yields inboth kharif and rabi seasons irrespective of source and time of application ofphosphorus. A dose of 60 kg P2O5/ha was found to be optimum in Rabiseason. Complex fertilizers like UAP, DAP, 28:28:0, 17:17:17 etc., were foundto be as good as straight fertilizers like SSP on equal nutrient basis in respectof grain yield. P content in grain, straw their uptake and also available P2O5content in post harvest soils. Spilt application has no advantage over entire



content in post harvest soils. Spilt application has no advantage over entirebasal application and in fact basal application has advantage over splitapplication in all most all the parameters studied. Phosphorus application hasa positive effect on P content in thirdly, grain, straw and also in build up ofavailable P2O5 content of soils.

II. Six years of experimentation on response of low land rice to potash in alluvialsoils of Godavari delta analyzing for medium to high available K2O revealedthat potash application at 30 to 45 kg/ha gave significantly higher grain yieldover control, soil test based K2O recommendation and farmers practice (15 kgK2O/ha). Higher yields were also obtained due to application of potassium inthe on farm trails conducted in farmers fields at Ajjaram (medium available K2O)and Kavitam (high available K2O) in two consequent seasons indication theneed for application of this nutrient irrespective of soil available K2O content. Adose of 30 to 45 kg K2O/ha was found to be optimum for getting higher yields. Further, it was found that split application of potassium has no addedadvantage over entire the basal application in these heavy soils.

Potassium application rice has not received adequate attention hitherto on the pleathat the soils are rich potassium. But the results of this experiment has lead to theconclusion that potassium application at 30 to 45 kg/ha is very essential irrespectiveof soil available K2O content for realizing high yields. Presently, rice farmers largely

follow this recommendation in both the seasons.

I. Studies on the analysis of irrigation and drainage water conducted for twoseasons revealed that irrigation water (canal water) during kharif season on anaverage carried 0.55 and 0.083 g of silt and clay per liter of water respectively,but the surface drainage water did not contain any silt and clay. Furtherirrigation water has relatively low salts (0.744 ds/m) and SAR (7.65) than thesurface drainage water (0.998 ds/m, 10.29 respectively).

II. Effect of organic matter or phosphorus availability to low land rice in Godavarialluvial soils was studied during 1996-2002 to evaluate the efficiency of greenmanure incorporation in solubilization of phosphorus from rock phosphate. Theresult that rock phosphate @ 40 kg P2O5/ha plus green manure incorporation@ 5t/ha increase the P uptake soil fertility and grain yield of rice significantlyover the corresponding rock phosphate treatments without green manure inneutral to alkaline soils. Single Super Phosphate on the other hand wasequally effective either with or without green manure.

III. Studies on affect of fly ash along with graded doses of FYM and NPK on yield,nutrient content and uptake in addition to soil characteristics in paddy revealedthe non-significantly role of fly ash and the importance of FYM for use withreduced doses of inorganic fertilizers. Application fly ash @ 10t/ha has noresulted any significant increase either grain yield and straw yield of rice overno fly ash application.

IV. Investigation on the effect of direct incorporation, composting and burning ofcrop residues on yield, nutrient content and uptake in addition to post harvestsoil characteristics in paddy revealed non-significance of the differenttreatments for the various parameters

Rice Seed Dormancy :

To release or recommend any variety for coastal ecosystem, during kharif season, thevariety should possess good seed dormancy characters. In order to achieve theobjective, the pre-release and released varieties from ANGRAU are being screened forthe duration and intensity of seed dormancy. Based on this information, some of thevarieties are being utilized as donors for this character by the Rice Breeders. It is alsouseful for the farmers to choose varieties for their locality depending on rainfallpattern.

Breaking Rice Seed dormancy :

Since the dormancy is a problem in the two cropped rice belt of Godavari districts inAndhra Pradesh ; the technique of Nitric acid treatment of seed (soaking seed in 0.1N nitric acid for 24 hours) has been found to be very useful in breaking seeddormancy and hastening the germination. This technique has become popular withthe rice farmers (75%), especially in situations where kharif harvest is delayed andrabi sowings have to be taken up immediately after harvest of kharif

To break rice seed dormancy soaking the seed in O.63 % Nitric acid solution(6.3 ml of HNO3 in 1 lt.) is recommended ( 10 ml of HNO3 in 1 lt. for MTU 1001and other strong dormant cultures).

Seed viability :

Rice seed viability of valuable seed material like germplasm, breeding materials etc.can be retained for a longer period effectively by storing them with calcium chloride(4:1 ratio).

High density grain :

The traditional varieties exhibited a higher potential of grain filling (H.D grain) viz., OR1108 (87%),MTU 15 (68%) and MTU 10 (67%). The total spikelet number and H.D.grain per cent was high in mother shoot followed by secondary and tertiary tillers.

Age of the Seedling :

Planting of overaged seedlings (60 days) during Kharif season reduced grain yieldssignificantly in rice compared to planting 30 and 45 days old seedlings. This was



significantly in rice compared to planting 30 and 45 days old seedlings. This wasmainly due to reduction in source capacity (LAI and Biomass) and sink components(Panicle and spikelet number ). The seedlings raised from the seeds obtained from previous kharif or rabi, whenplanted during next rabi did not exhibit any significant differences in vigour, growth ofseedling, physiological and productive efficiencies.

Optimum time of Planting :

Delayed plantings either in kharif (August to October) or in Rabi (January, February)caused marked reduction in grain yields because of reduction in vigour, growth,source capacity, sink components and harvest index. To obtain optimum growth andmaximum productive efficiency, plantings have to be completed before July 15th(Kharif) and December 15th (Rabi).

Split tiller planting :

The Practice of planting split tillers at 30 days after normal planting leads to a grainyield reduction of 20% over normal planting, due to reduction in source capacity andsink components. However, this method of planting split-tillers can be utilized as acontingency plan under flood damage situation.

Photo period sensitivity :

The nature of photosensitivity in popular kharif rice cultures were assessed based onthe flowering duration under staggered plantings. Most of the modern high yieldingvarieties were weakly photosensitive and their flowering duration was reduced withan advancement in the time of planting. The total duration also was reduced by 10 –15 days when these weakly photosensitive kharif varieties were planted during Rabiseason.

Rice productivity and its relationship with physiological parameters :

Biomass production, leaf area index and filled grain number are the majordeterminants of grain yield in varieties of rice. The varieties with high physiologicalefficiency characters were recommended to breeders for using them as donors:

Growth regulators:

Growth regulators viz., Foliar spray of growth regulators viz., Atonik, Mixtalol,Cytozyme, Miraculan, Symspray and Homobrassinolides did not show any beneficialeffect in improving rice yields.

Moisture stress:

Evaluation of rice varieties under natural moisture stress condition has lead to theidentification and release of MTU 9993 and Maruteru Sannalu (MTU 1006) for rain-fedrice ecosystem.

Water Submergence (Excess Moisture):

Complete submergence of Rice plants for 10 days had a more drastic effect than 7days submergence. The variety MTU 4870 exhibited higher recovery at all stages. Areduction in tillering source capacity and sink were observed under submergence.

Donors identified for different characters:

National Methane gas campaign:

Actively involved in “National Methane gas campaign” and quantified the Methanegas emission in low land rice fields of Godavari delta, through ICAR – AP Cess Fundproject entitled “Methane Emission in Rice based cropping system”. It was found thatRice crop emitted low Methane 2.17 mg/m2/hr-1 . Varietal and growth stage variationwere observed in methane gas emission from the rice fields. The Methane gasemission was low at vegetative phase, increased gradually up to flowering anddeclined later. Gypsum application has reduced Methane emission. Pillipesara crophas emitted lower Methane than Rice in the Rice Based Cropping System. Methaneemission was low in upland rice, as compared to wet land and irrigated rice.

The data-base on Methane emission has disproved the apprehensions that rice cropis the main culprit in environmental pollution, as the methane emission was muchlower (only 20% of predicted values).

2. FACILITIES AVAILABLE:

Insect poly houseField screening for planthoppersMass culturing of planthoppersField evaluation of insecticides against insect pests of rice

3. CONTRIBUTIONS:

1. GERMPLASM EVALUATION AND UTILIZATION:

A total of 17,335 germplasm accessions/ rice cultures/ entries were screenedfor resistance/tolerance to planthoppers. Among these 1138 entries exhibited

moderate to high field tolerance. Out of these 14 entries recorded damagescore of ‘0’, 270 entries with damage score ranging from ‘1-3’ and 854 entrieswere moderately field tolerant.

Eight planthopper resistant donors viz., PTB 33, Velluthacheera, HuruHonderwala, Rathu Heenati, PTB 12, Manoharsali, CRMR 1523 and ARC 6650were identified. MTU IJ 206-7-4-1 (BM 71) has been identified as newresistant donors having strong resistance to planthoppers.

Tolerant varieties against planthoppers viz., Vijetha (MTU 1001) Cotton dorasannalu (MTU 1010), Deepti (MTU 4870), Tolakari (MTU 1031) and Godavari(MTU 1032), Indra (MTU 1061) were released in the state.

A total of 584 entries were screened for multiple pest resistance/tolerance andidentified 43 entries tolerant to planthoppers and 19 to leaf folder.



2. PEST MANAGEMENT STUDIES:

New insecticide molecules viz., ethofenprox 10EC @ 1.5ml/L, imidacloprid @0.2ml/l (25 g a.i./ha), thiamethoxam 25WG @ 0.2g/l (25g a.i/ha) againstplanthoppers, Acephate 75SP @ 1.5g/l against planthoppers, leaf folder andstem borer. Cartap hydrochloride 4G @ 8 kg/ac, cartap hydrochloride 50WP @2g/L, flubendiamide 48 SC @ 1ml/L and flubendiamide 20 WDG @ 2.5 g/Lagainst leaf folder and stem borer were found very effective. Among thesecartap 4G, cartap 50 WP and ethofenprox were relatively safer to spiders andmirid bugs, while, Acephate and Imidacloprid moderately safe to these naturalenemies.Use of pheromone traps @ 3traps/acre for monitoring and 8 traps/acre formass trapping have been recommended for management for rice yellow stemborer after conducting field demonstrations for two years.The occurrence of panicle mite, Steneotarsonemus spinki in K.G.zone wasreported for the first time and it can be managed by spraying withprofenophos @ 2 ml or dicofol @ 5 ml /L of water, once at panicle initiationstage and another at 15 days later.

Ethofenprox + hexaconazole and Acephate 75 SP + hexaconazole effectivelycontrolled planthoppers and sheath blight. While, Cartap hydrochloride 50WP+hexaconazole and Acephate 75SP + hexaconazole effectively controlled sheathblight, leaf folder and stem borer.

Action plan for the management of planthoppers :

1.Grow planthopper tolerant varieties: Vijetha, Cottondora sannalu, Indra 2. Form alleyways3. Adopt wider spacing: 20 x 15 cm (Kharif), 15 X 15 cm (Rabi)4. Apply recommended doses of fertilizers: 60:40:30 kg NPK/ha (Kharif) 120:60:40 Kg NPK/ha (Rabi)5. Practice alternate wetting and drying6.If planthopper population exceeds 20-25 nos/hill adopt plant protection with thefollowing

insecticides:

1st Spray : Imidacloprid (50 ml/ac)/Thiamethoxam (40 g/ac) * 2nd Spray : Monocrotophos (440 ml/ac)/Acephate (300 g/ac) 3rd Spray : Ethofenprox (400 ml/ac) 4th Spray : Fenobucarb (400 ml/ac)

If the populations are high at the first instance, avoid * neonicotinoid chemicals.

NOTE: 1. Use 200 lt of spray fluid/ac and the spray should be directed towards the base of the plant 2. Do not use any insecticide mixtures

3. Alternate the insecticide for the next spray with another group of chemical as shown above 4. Drain the field immediately after the spray for one or two days. 5. Avoid the use of synthetic pyrethroids and unrecommended Chemicals.

3. ASSESSMENT OF YIELD LOSSES:

Damages due to planthoppers and stem borer (White ears) accounted forsignificant variation in yield during Kharif (Y = 3.3 +1.1** (total tillers)-0.27**(BPH no.s) and Y = 13.7 +0.8** (PBT) – 0.3** (WE) – 0.03 (sheath blight)). During Rabi white ears due to stem borer had significant impact on yield (Y =17.373 - 0.2** (WE)).

4. POPULATION DYNAMICS OF RICE INSECT PESTS:

Yellow stem borer occurs in 3 broods during kharif and 2 broods in Rabi. Second brood (October) in kharif and Second brood (February) in Rabi inflictedsevere damage. Leaf folder recorded 3 broods in Kharif and 2 broods in Rabi.Second brood in Kharif and first brood in Rabi inflicted severe damage.Planthoppers build up in 3 generations in both kharif and rabi seasons. Thesecond generation in both the seasons inflicts maximum damage.

5. INTEGRATED PEST MANAGEMENT:



5. INTEGRATED PEST MANAGEMENT:

Created awareness among the farming community about the IPM practices anddeveloped two IPM modules for K.G. Zone i.e., cultivation of a BPH tolerantvariety with need based application of insecticides against other major pestsand diseases or cultivation of BPH susceptible HYV with timely plant protectionagainst planthoppers realized higher benefit cost ratios.
