This will subject the variety to differences in soil and climatic conditions that occur throughout the State. The most common limiting factor in soybean production is inadequate moisture during pod development and filling. Soybeans are highly photoperiodic, the blooming period, period of pod development and fill, and maturity date of a particular variety do not vary greatly from year to year. Continued testing and evaluation of soybean varieties and experimental strains are essential if farmers, county extension agents, seedsmen, and other agri- cultural workers are to be provided with information to help them select varieties best adapted to their locality and individual requirements. EXPERIMENTAL PROCEDURES All tests were conducted at outlying units of the Alabama Agri- cultural Experiment Station of Auburn University. A randomized block design with 4 replications was used at each of 8 locations. One to three planting dates were used at each location with the first plantings made at the optimal time for maximum yield. Plots were planted with regular commercial soybeans planters equipped with a special seed hopper adapted for small plots. Plots were four rows wide and 23 feet long with 16 feet of two center rows harvested for yield determinations. Row width varied from 36 to 42 inches depending on location. Seeding rate was 10 viable seed per foot of row. The entries included in these tests were varieties released prior to 1975 and a number of unreleased strains in the late stages of evaluation. DISCUSSION OF DATA Varietal performance may vary from year to year because of variation in rainfall, temperature, diseases, and nematodes. Therefore, long term studies are necessary in order to properly evaluate varietal performance. Differences in the yield for 1 year's data which may be due to chance, have been computed using least significant difference (L.S.D.) at the 5% level of probability. The L.So.D. and the coefficients of variation (C.V.) are footnoted in yield tables for 1975 yield data only. The C.V. reflects the precision in estimating the relative performance of varieties. SEASONAL CONDITIONS Early season moisture was good at all locations and good stands were obtained in all tests. Early growth was good at all locations as there was an average rainfall of .9 to 2 inches per week for the first 6 weeks for early plantings and from 2 to 3.5 inches per week for the 6 weeks period following plantings made in late June. This early rainfall caused some excess plant growth and lodging problems at Tennessee Valley Sub- station and Sand Mountain Substation in North Alabama and Prattville Field and Wiregrass Substation in central and South Alabama respectively. There was a 16 to 24-day moisture stress period at all but two locations during the last 2 weeks in August and first 2 weeks of Septem- ber. The two locations with no moisture stress during pod fill were Brewton Field and Gulf Coast Substation. The total rainfall from August 15 through September 30 is shown in Table 1. The total rainfall at each location was good for this period, and does not reflect the 2 to 3-week stress periods mentioned above. This stress period seemed to effect the mid season varieties in early planting and early varieties in the late planting tests more than other varieties. Table 1.

For example Essex yielded 62 bu/A at Tennessee Valley Substation and 34 bu/A at Sand Mountain Substation. The late or full season varieties yielded the best at the later planting dates throughout the State and early planting dates in the southern locations. For example Hutton yielded 51 bu/A and Coker 338 yielded 39 bu/A for first and second planting respectively at Brewton Field and Ransom yielded 56 bu/A at Gulf Coast Substation. Seed quality was fair to poor at most locations and in general the early varieties had the poorest quality, particularly when planted at the early planting dates. DATA RECORDED The yield of a crop is the primary factor of production when profits are to be maximized. Other characteristics which are important are plant height, height of 1st pod, maturity, lodging, and size and quality of seed. 7' t -. 0 * *~ 'T r f ~f I - 2- N l~ ~~0&0 ~9 ~~0 ~0f 0.0~. ~ 0~ C ~ ~ ~ - 0~ ~ - ~ Lodging was based on a scale of 1 to 5 according to the following criteria and illustrated by figures 1 through 5 respectively. 1 - almost all plants erect. 2 - either all plants leaning slightly (less than 450) or a few plants down. 3 - either all plants leaning moderately (ap- proximately 450) or 25 to 50% of the plants down. 4 -either all plants leaning considerably (more than 450) or 50 to 80%o of the plants down. 5 - all plants down. ~- 11% -t ~0 ~% ~'~~gwi~ *0*~ 0~ .~ A ~ - > r ifs f ; .

Plot yields were adjusted to 13% moisture and converted to a bushel weight of 60 lb and recorded as bushels per acre. Maturity was recorded as the date when the pods were dry and most of the leaves had dropped. Under most conditions, the stems were also dry. Plant height was determined as the average length of plants from the ground to the top extremity at time of maturity. Height of first pod was determined as the average height of the lowest pods from the ground at maturity. Seed size for each variety was determined from a composite sample of all replications at a given planting date and location. Seed size is reported as grams per 100 seeds. Seed quality was based on a rating from 1 to 5 according to the following scale: (1) very good, (2) good, (3) fair, (4) poor, and (5) very poor. The factors considered were development of seed, wrinkling of seedcoat due to late harvesting and to excessive rain. Purple stain ratings were obtained by counting stained seed and expressing on a scale of 1 to 5 as follows: 1 - no purple staining 4 - 9 to'19% seed purple stained 2 - 1 to 3% seed purple stained 5 - over 20% seed purple stained 3 - 4-8% seed purple stained VARIETY DATA Soybean varieties grown in Alabama are in Maturity Groups V, VI, VII, and VIII.
