Reproduction stocking changes following prescribed burning in different growth areas areshown above.
TEN YEARS AGO about a third of Ala-bama's farm income was from sale oflivestock and livestock products. Todaylivestock brings in 55% of the State'scash farm receipts.
Growth in livestock production hasgreatly increased needs for feed. Sincefeed is the major cost item in producinglivestock, price of feed has an importantbearing on farm profits.
Price Changes
Prices paid for mixed feed and forfeed concentrates (except cottonseedmeal) went down in Alabama during1956-60. The change was both gradualand continuous for almost every kind offeed.
Cost of corn meal for feed in 1960was down 16% from the 1956 price, butsoybean meal dropped only 3%. Re-ported farm prices for broiler growingmash, laying mash, and mixed dairy feedwere down 8, 6, and 4%. Farmers paid12% more for cottonseed meal in 1960than they did in 1956.
Feed-prices fluctuated much less withinthe year than did prices of farm pro-ducts. Prices tended to be highest inJuly and August and lowest in Novem-ber and December. The feed having thegreatest seasonal change in price wascorn meal. It increased an average of10% between the low in December andthe high in August. Laying mash had themost constant average monthly price,showing only a 3% increase betweenNovember and June.
Price data demonstrate that there wasnot a close relationship between priceof feed and price of the principal pro-duct produced. The usual proportionalchange in average price of eggs is greaterthan the change in prices for other ag-ricultural products.
Area Comparison
Continued expansion of livestock andpoultry production in Alabama will beinfluenced by the price of feed in rela-tion to other areas. To show the rela-tive levels, 5-year averages of prices for
three mixed feeds and three importantfeed ingredients were compared for eightstates. These states represent five areasof the United States (see graph).
Arkansas had a price advantage for allfeeds except corn meal, for which pricewas lowest in Iowa. Prices in Alabamawere below those in Georgia and NorthCarolina, and were lower than in Mis-

sissippi for broiler growing mash andlaying mash. However, prices for broilergrowing mash and laying mash werelower in Iowa, Ohio, and Delaware thanin either of the Southeastern States. Soy-bean meal was most expensive in Dela-ware, whereas cottonseed meal was mostcostly in Ohio. Price differences amongstates were greatest for cottonseed mealand least for mixed dairy feed.
Feed Use Increasing
During the 5-year period of 1956-60,total Alabama feed sales increased atan average rate of 12.3% per year. Tonsof poultry feed reported sold were 89%greater in 1960 than in 1956.
Some states that had lower feed pricesdid not experience an expansion in useof feed similar to that which took placein Alabama. Among the reasons werelower feed conversion ratios obtained,existence of profitable alternative op-portunities, less favorable climate, andhigher costs for other production items.
A relatively low price for feed is onlyone factor that contributes to expansionof livestock and poultry enterprises, butit is an important one. Efficient facilitiesfor handling and processing feed are es-sential in maintaining competitive feedprices and to continued expansion oflivestock and poultry industries in theState.
FIELD TURNING SPACE
needed or
TRACTOR EFFICIENCYELMO S. RENOLL, Associate Agricultural Engineer
CAN YOU cultivate as many acres perday as you think you should? Does yourneighbor get more capacity from his rowcrop machines than you do?
Field capacity of farm machinery var-ies greatly from field to field and is in-fluenced by many factors. Some havebeen analyzed and their effects deter-mined. Other factors, such as turningspace, physical condition of turning area,and turning time, are being studied atAuburn University Agricultural Experi-ment Station.
Turning Time
Time spent turning the tractor in rowcrop operations may amount to 25% ofthe field time. Any reduction in timeneeded to make these turns would in-crease machine efficiency and field pro-ductive capacity.
The time needed to complete a singleturn in row crop work depends mainlyon width of available turning space andground surface condition in turning area.A narrow space that requires backingthe tractor will increase turning time.Turning on rough area will also result inlonger than normal time.
Turning Space and Pattern
Width of turning area will nearly al-ways dictate the type of turning patternused. Space large enough to turn a trac-tor in an easy semi-circle pattern willusually result in the least turning time.A narrow turning space will require alonger than minimum time.
Some common patterns used to turntractors doing row crop work are shownin Figures 1, 2, and 3. The turning spacein Figure 1 is wide enough for an easy,normal turn. In Figure 2, the turn spaceis too narrow for turning the tractor
without backing. This pattern requires50% more time than a normal turn. Theturning pattern in Figure 3 is used infields having no turning space at end of
row. This type turn may double thenormal turning time.
Surface Condition
Physical condition of the surface inturn area can greatly affect the timeneeded to complete the turn. Roughground, rocks, ditches, or other obstruc-tions in the turning area will increasethe turning time. The table shows how
obstructions in the turning area affecttime needed to complete the turn.
Under the conditions of these tests,obstructions in turning area increasedthe turning time by as much as 29%.Ditches in the area increased turningtime by about 25%, while turning on arough area resulted in an 11% increasein turning time.
Summary
1. Turning space at the edge of rowcrop fields should be wide enough toturn the tractor and equipment in aneasy semi-circle turn. A narrow turningspace may increase the turning time byas much as 50%. In the case of fields hav-ing no space beyond end of rows, theturning time may be double.

2. Physical condition of the groundin turning area will affect turning time.Smooth turning areas require a minimumof turning time, whereas obstructionswill materially increase it.
3. Turning space at edge of field makesit easier to operate large machines, suchas a cotton picker or corn picker, andalso helps to keep ends of rows free ofweeds.
Increased field efficiency obtained byusing a turning space that is both ade-quate in size and free of obstructionswill make it possible to (1) handle moreacres with a given size tractor or (2)to use smaller and less expensive ma-chinery for a given acreage.

P LANTING OATS at the right time canput more dollars in your pocket. Re-search results show that yields of oatscan be increased by planting earlierthan is the usual practice.
Experiments on dates of planting oatswere conducted during 1952-57 by theAuburn University Agricultural Experi-ment Station. The tests at seven loca-tions were designed to measure effectof date of planting on yields of oatsgrown for grain only and for forage andgrain combined.
Two Management Systems Tested
Oats were seeded at the rate of 3 bu.per acre. Two series of plots were usedat each location with one series managedfor grain production only. These plotsreceived adequate rates of phosphateand potash fertilizers at planting. Fiftylb. of nitrogen was applied as a top-dressing about March 1.
Another series of plots was managed
for production of forage (grazing) andgrain. These plots received the samephosphate and potash fertilization atplanting as those managed for grainonly. In addition, a topdressing of 50lb. of nitrogen per acre was appliedwhen oats were up to a stand. Forageremoval was discontinued about March1 and an additional 50 lb. of nitrogenper acre was applied. All. plots in bothseries were allowed to mature a crop ofgrain and grain yields were measured.
When consumed as green pasturage,1 lb. of dry matter from oat forage isconsidered equal in feed value to 1 lb.of oat grain. This factor was used toconvert forage yields to grain equiva-lents in measuring yields.
As shown in Figure 1, forage yieldsfor comparable dates were highest insouthern Alabama. There was little dif-ference in forage yields for comparabledates between central and northernareas of the State. Highest grain yields

FIG. 4. Shown here are yields of oats man-aged for grain only from different plantingdates in 1952-57 experiments.
on clipped plots for all planting dateswere produced in northern Alabama,followed in order by central and south-ern regions, Figure 2.
A comparison of Figures 2 and 4shows that yields of grain were decreasedby clipping, but the forage obtainedmore than compensated for the loss.When forage and grain yields were com-bined, there was little difference in max-imum per acre production of feed inall regions, Figure 8. However, therewas a difference in the best date to plantfor maximum yields.
Best Planting Dates
Recommended planting dates for for-age and grain production in the threeregions are: northern Alabama, Sep-tember 1 to September 20; central Ala-bama, September 1 to September 30;and southern Alabama, September 20 toOctober 20. Planting dates did not ma-
terially affect yield of oats grown forgrain only in any of the regions, Figure4. The maximum difference, 8 bu. peracre, occurred between the September10 and October 20 planting dates incentral Alabama. This indicates thatmost any of the planting dates in any ofthe State's regions is satisfactory forgrain production only.

C O N T A I N : R Sproblem
C ONTAINERS USED in marketing are animportant problem of Alabama's vege-table industry. Produce is received bywholesalers in a great variety of pack-ages. Even for the same commodity,containers vary widely in size, dimen-sions, and construction. Produce grownnearby is often delivered in bulk and inopen trucks without refrigeration. Onelarge handler reported receiving snapbeans in shoe boxes.
Magnitude of the container problemwas learned in an Auburn AgriculturalExperiment Station study of procure-ment practices and problems of whole-sale handlers of fresh vegetables in theState. A major objective was to investi-gate ways to increase marketing effi-ciency.
Representatives from 4 major chains,3 brokers, 23 carlot receivers, and 32jobbers were interviewed. Most freshproduce offered for sale in Alabama re-tail stores was channeled through oneor more of these firms. In order of im-portance, firms purchased from broker-receivers, growers, shipper- growers,farmers' markets, jobbers, and repackers.Fresh vegetables from 39 states andforeign countries were brought into Ala-bama by the firms studied.
Containers Preferred
A summary of wholesale dealers' con-tainer preferences for major commoditiesis presented in the table. Several pre-ferred containers were named for green-ripe tomatoes, collards, cucumbers, limabeans, rutabagas, turnips, and strawber-ries. The 12 commodities listed in thetable were selected on the basis of vol-

ume handled from a total of 39 beingsold by wholesale firms.
In 35 of the 62 firms studied, snapbeans were of major importance. Thirty-two of these 35 firms preferred the prod-uct to, be delivered in bushel hampers.Of the 39 firms reporting cabbage ofmajor importance, 35 expressed prefer-ence for the 50-lb. mesh bag and theremainder preferred crates. All 39 re-ports concerning head lettuce favored afiberboard vacuum-cooled package.
Fifteen of the 19 firms reporting newpotatoes as a major commodity preferred50-lb. bags, 3 preferred 100-lb. sacks,and the other, which had bagging equip-ment, chose to receive in bulk.
The 20-lb. fiberboard box was thechoice of 25 of the 33 firms handlingpink tomatoes as a major commodity.Two firms desired the 40-lb. fiberboardbox, three the 60-lb. wirebound crate,and one each preferred the 60-lb. fiber-board box and bulk delivery.

General Agreement Found
There was much agreement on con-tainer preference for specific commodi-ties. More than half of all reasons givenfor container preference involved qualitymaintenance and standardization of thetrade. A few containers for each com-modity capable of meeting these require-ments permits quick and easy trading,according to the buyers.
Price discounting was reported wherea variety of sizes and types of containerswas used. Ease of handling, customersatisfaction, and ease of display wereother reasons given for specific containerpreference.
Facilities available to marketing firmsfor handling commodities were relatedto container preference. One of the chainorganizations had bagging and boxingequipment to service their retail outlets.Seventeen of the 23 carlot receivers hadboxing and bagging equipment as com-pared with only 4 of the 32 jobbers. Allof the earlot receivers and jobbers hadadequate boxing and bagging equipmentfor present use, but only 12 of the car-lot receivers and 3 of the jobbers hadadequate facilities for the future.
The likely continued increase in chainstore handling of vegetables may requirebetter packaging of produce nearer thepoint of production. The trend towarddirect marketing means that producersand shippers will have to give closer at-tention to acceptable containers thanthey have in the past. Inferior and non-standardized containers are costly interms of quality loss, cost of repacking,and price discounting. Packages will needto be easy to handle, stack, and load tobe shipped with confidence.
Marketing efficiencies achieved canbenefit farmers, distributors, and con-sumers: through higher profits, lowerprices, and better qualtiy of producemarketed.

INOCULATION and its importance to suc-cessful production of certain leguminouscrops is common knowledge among Ala-bama farmers today.
But few know that some of the firstresearch in this country with inoculumor "germ fertilizer" was done at the Au-burn Agricultural Experiment Stationmore than three score years ago. Its re-sults provided the answer to the mysterywhy certain leguminous plants producepoor yields on soils on which no legumehad been recently grown. Legumes usedin this early work included vetch, crim-son clover, lupine, lespedeza, alfalfa,Canada field peas, and cowpeas.
"The subject of maintaining fertilityof the land very closely concerns everytiller of the soil, whether cotton planter,tobacco grower, grain farmer, livestockbreeder, or horticulturist."
The foregoing paragraph is the in-troduction to Auburn Station BulletinNo. 87, published in the summer of1897, reporting early research on soilinoculation for leguminous plants. Thewords are those of the late Prof. J. F.Duggar, who joined the Auburn staff ayear earlier and whose later work madeit possible to condition the soil for grow-ing certain legumes to supply muchneeded nitrogen. He is credited withhaving been one of the first researchersin this country to have experimented with"artificial cultures" for growing cloversand other legumes.
In the light of discoveries in Europe,Professor Duggar determined that someAlabama soils had to be inoculated bythe necessary germ-life to grow legumes.First with a homemade preparation andthen with a patented concentrate fromGermany, he launched a long-range cam-paign to get Alabama farmers to inocu-late their fields so soil improving leg-umes could be grown.
In Station Bulletin 87, Professor Dug-gar in the main presented results fromgreenhouse pot experiments in which hecompared growth of inoculated and un-inoculated legumes. His yield increaseswere dramatic.
Professor Duggar emphasized thevalue of inoculation in Bulletin No. 96,published August 1898. Reporting onexperiments with crimson clover andhairy vetch, he wrote, "clover, vetch,and similar leguminous plants are ableto draw much of their nitrogen from theair when enlargements called tuberculesor nodules are found on their roots. They
are unable to do this, or to store up fer-tility, when tubercules are absent.
This is the second article of a serieson Auburn University and its Agri-cultural Experiment Station System-its founding and its contributionsdown through the years to the prog-ress of Alabama's agriculture. Theseries is being published in conjunc-tion with Auburn's Centennial Cele-bration.-Editor
"In order for tubercules to develop,specific germs of bacteria must come incontact with the young rootlets. In theregions where the clovers, vetch, alfalfa,etc. are extensively grown, these germsbecome generally distributed in the soilof the entire region. In a number of lo-calities in Alabama, where these legumesare not grown to any great extent, thesegerms are absent from some soils orpresent in insufficient numbers."

The researcher reported good resultsfrom two methods of inoculation: (1)scattering on a field some of the germ-laden soil from a field where the leg-umes have borne tubercules, and (2)use of a prepared material called Nitra-gin, "a concentrated germ fertilizer con-taining myriads of germs which are ableto cause the growth of tubercules on theroots of certain leguminous or soil im-proving plants."
Large yield increases in field experi-ments resulted from the use of an inoc-ulum, as reported in Bulletin 96. Hairyvetch inoculated with vetch Nitraginproduced hay at the rate of 3,270 lb.per acre, as compared with 564 lb. with-out inoculation. Using soil from an oldvetch field as inoculum increased yieldby 2,308 lb. of hay over an uninoculatedcompanion plot. Crimson clover yield in-crease from inoculation was reported tobe 3,296 lb.
Long lasting effect of inoculation wasalso learned. It was reported that "'a fieldonce inoculated, whether naturally orartificially, remains inoculated for years."Other information included the fact that,in general, each genus of leguminousplant has its own specific or adaptedgerm.
Successful growth of legumes in Ala-bama was a major breakthrough that hasbeen invaluable to farmers of the State.Use of these crops as soil improving andforage plants came about as a direct re-sult of the early, basic research.
Research on legume production hasnot stopped. Work has continued throughthe years on variety testing and devel-opment, time of planting, seedbed prep-aration, fertility requirements, and onother cultural practices. This ongoing re-search continues to provide informationthat enables farmers to do a better jobof legume production and utilization.
