This will subject the variety to differences in soil and climatic conditions that occur throughout the State. The most com- mon limiting factor in soybean production is inadequate moisture during pod development and filling. Since soybeans are highly photo periodic, the blooming period, period of pod development and fill; and maturity date of a.particular variety do not vary greatly from year to year for a given planting date. Thus, it is important that varieties from more than one maturity group.be evaluated at each location. Continued testing and evaluation of soybean varieties and experimental strains by agricultural experiment stations are essential if farmers, county extension agents, seedsmen,. and other agricultural workers are to be provided with information to help them select varieties best adapted to their locality and management needs. EXPERIMENTAL PROCEDURES Tests in central Alabama were conducted at five substations or experiment fields of the Alabama Agricultural Experiment Station of Auburn University. A randomized block design with 2 to 4 replications was used at each location with the first planting made at the optimum time for maximum yield. Plots were planted with regular commercial soybean planters equipped with special seed hoppers adapted for small plots. Plots were four rows wide and 23 feet long with 16 feet of the two inner rows harvested for yield determinations. Harvest was done with a small plot combine at all locations. Row width varied from 36 to 39 inches depending on location. -Seei~ng rates were 10 viable seed per foot of row based on germination at 75 F. All plot areas were fertilized according to soil .test. The entries in these tests included varieties released prior to 1981, a number of unreleased lines in the late stages of development from the USDA.Regional Testing Program, and some commercial lines. Sources of seed are listedon pages 11 to 13. The tests in central Alabama were located on Houston clay and Vaiden clay near Marion Junction, Lucedale sandy loam near Prattville, Cahaba sandy loam near Camden, Wickham sandy loam near Tallassee, and Orangeburg sandy loam near %Shorter. Soybeans of maturity groups VII and VIII are full season varieties in this area. Varieties of maturity groups V and VI are very early and early, respectively. The test near Camden had irrigation water applied with overhead sprinklers to half of the six replication tests. Two inches of water was applied to the irrigated plots on each of the following dates: 08/06, 08/18, 08/26, 09/25, and 10/01. DISCUSSION OF DATA Since results of field plot research are influenced by inherent soil differences and soil moisture availability, it is not possible to determine exactly the yield potential of a variety at a given location. Varietal performance may also vary from year to year because of variation in rainfall, temperature, diseases, and nematodes. Therefore, long term yield averages are more reliable in evaluating varietal performance. Differences in yield for 1981 have been computed using Duncan's Multiple Range Test at the 5% level of probability. Yields followed by the same letter are not considered to be significantly different. Seasonal Conditions Early season moisture was adequate in central Alabama in 1981 and good stands were obtained at all May plantings. Inadequate stands were attained from the June planting at Prattville Field; therefore, the test was abandoned. However, good stands were obtained at the Black Belt Substation on June 2 and June 26 plantings. There were three severe drought stress periods in central Alabama during the growing season. These periods lasted for 2 weeks in late June, 4 weeks in late July and early August, and 4 weeks in late September and early October. The dry period in June 1981 was a stress period during vegetative growth resulting in short plants at all locations.. The dry period in late July and early August came during the bloom and early pod development of the early and very early varieties and the late vegetative and bloom stages of the full season and late maturing cultivars. The dry period in late September and early October was during the pod fill period of the maturity groups VI, VII, and VIII. Lowest yields were made by the late Maturity Group VIII cultivars. Marion Junction (tables 3-19) Plantings were made on May 12 at two different sites on'.the Black Belt Substation in 1981. The Sumter soil site had been in row crops for more than 15 years and had been in soybeans for the past 3 years. In 1980, the .Vaiden soil site was rotated from pasture to soybeans in 1981. Soybean innoculum (granular Nitragin) was p laced in the drill with the seed at planting. The severely dry June (1.96 inches total rainfall) resulted in stunted and iron chlorotic soybeans on the Sumter soil. The cultivars were rated on the degree of stunting and chlorosis and these ratings had a significant negative correlation with final yield, table 18. The Vaiden soil did not show any moisture stress during this period as all entries continued to grow and were taller than 30 inches with the exception of two Group V entries. In the Sumter soil only 5 full season entries were taller than 30 inchhs. The second stress period occurred -2- July 12 through August 7 when only 2 inches of rainfall occurred during during the early bloom stages and pod set period for the late Group VI entries and the full season varieties of Groups VII and VIII. The final yield was a good. indication of the moisture relations during pod fill. The highest yielding varieties as a group were the Group VI entries. On the Vaiden soil 9 of the 10 leading varieties were Group VI with average yields of 44.3 bu./a. The 5.7 inches of rainfall in August and first week in September favored pod fill of the Group VI entries. However, rainfall of only 0.7 inches in late September resulted in the lowest average yields of 32 bu./a. from Maturity Group VIII entries. The yields from the Sumter soil averaged 13.6 bu./a. while the Vaiden soil averaged 35.4 bu./a. for the same 47 entries planted the same day.. The soybean yields at the Black Belt Substation were also affected by a fungus -disease, stem canker, caused by Diaporthe phaseolorum var. caulivora. There was a disease rating taken on the soybean plots grown on both soils. This disease was more severe on the Sumter soil where beans had been grown in previous years. The damage also showed up earlier on the Sumter soil than on the Vaiden soil. The disease ratings are shown in table 19 on a scale of 1 to 5. A rating of one was given to plants with no disease evident while 5 showed very severe infection. These disease ratings were highly negatively correlated with yield. Prattville (tables 24-28) The early drought stress period at Prattville was the most severe as there was only 1.1 inches of rainfall the first 2 weeks in June and 0.3 inches the last-2 weeks of June. Plant height of the early (Group VI) and very early (Groups IV and V) entries were extremely short (14 to 34 inches at harvest). The 26-day period from July 12 to August 7 was more damaging to the Group IV and Group V entries as they were under a moisture stress during pod set, early pod development, and early pod fill. The rainfall of 5.2 inches during August 8 through September 5 was most favorable for Group VI entries as five of the leading eight varieties were in this maturity group. The third drought stress during late September and early October was most injurious to the Group VIII entries as they were the lowest yielding as a group. Coker 488 yielded 34 bu./a. compared to 23 bu./a. for the average of eight Group VIII entries. The highest yielding cultivars over the past 4 or 5 years have been in Group V or very early maturity group. This has been due to very low rainfall in four of the past 5 years during the period of August 15 through September 30, table 1. Shorter (tables 29 and 30) The yields at Shorter during the past 2 years have been very similar to those at Prattville. The early moisture stress resulted in a very short plant and only a few of the Group VIII cultivars had enough foliage to close the middle of the 39-inch rows. -3- Camden (tables 20-23) The variety test at Camden consisted of 46 entries that were both irrigated and non-irrigated. The rainfall at Camden was very similar to the other locations in central Alabama with the exception that 2 inches of rainfall fell in late July as compared to 0.2, 0.9, and 1.0 inch at Marion Junction, Prattville, and Shorter, respectively. Despite this rainfall there was moisture stress during this period. Irrigation was started August 6. Group IV entries responded less (only 5.9 bu./a. increase) to irrigation than did any other maturity group. The full. season varieties were the lowest yielding group without irrigation (21.5 bu./a.) and showed the greatest response to irrigation of 17.3 bu./a. average for the. 11 entries. Group VII entries averaged 40.3 bu./a. as compared to 38.8 bu./a. for both Group VIII and Group VI entries. The Group V and Group IV entries averaged 36.4 and 32.8 bu./a., respectively, under irrigation. The yield of Dowling was increased the most, 23.2 bu./a. with irrigation; however, Deltapine 105 was the highest yielding entry 48.5 and 33.8 bu./a. with and without supplemental irrigation, respectively. Effect of Planting Date on Yield The highest yielding cultivars at the Black Belt Substation over the past 4 years have been the Maturity Group VI cultivars with an average yield of 27 bu./a. when planted in mid-May. The 4-year mean yields of Group VII and Group VIII cultivars planted in mid May were 26 and 24 bu./a., respectively. When planting was delayed by 3 weeks the above yields were 23, 24, and 21 bu./a. for the maturity groups VI, VII, and VIII, respectively. Another 3-.week delay in planting to the last week of June resulted in yields of 18, 18, and 16 bu./a. for the above groups, respectively. When soybeans were grown on Sumter clay near Marion Junction during the year 1978 through 1981, an 8% to 15% reduction in yield occurred due .to delayed planting by 3 weeks after May 10 and a 31% to 33% reduction in yield when planting was delayed 6 weeks to the third week in June. Seed Quality and Purple Stain (tables 31 and 32) Seed quality and purple stain ratings are shown in tables 31 and 32. Generally, in 1981 the seed quality was poorer in central Alabama than it was in north Alabama. Also, the seed quality was poorer on the Sumter soil at Marion Junction than the Vaiden soil location. It was also poorer on the non-irrigated test at Camden than under irrigation. The seed quality at Marion Junction appeared to be associated with both early maturity entries and those entries that showed a high level of stem canker disease, table 19. -4- Seed Size (table 33) Seed size (g/100 seed) is usually affected by two factors, genetic and soil moisture availability during late stages of pod fill, table 33. The seed size was much larger from the irrigated area at Camden than from the non-irrigated area, indicating very severe moisture stress particularly in the late maturing cultivars. Seed size was much larger at the Marion Junction Vaiden soil location indicating a much more favorable moisture relationship of the soil recently taken out of pasture. USDA Regional Test (tables 34-36) A preliminary test in Maturity Group VII and uniform tests in maturity groups VII and VIII were evaluated at Tallassee in 1981. These tests are shown in tables 34, 35, and 36. In the .preliminary Group VII test, Braxton is used as the standard variety. Braxton and Wright are the standard varieties in Uniform VII tests and Cobb and Hutton are the standard varieties in Uniform VIII tests. In the preliminary tests only one line yielded better than Braxton, however, in the Uniform VII test there were five lines that yielded better than the standard entries with D77-7920 and F77-1576 yielding 7.0 and 9.0 bu./a., respectively, better than Braxton. In the Uniform VIII test a number of lines yielded lower due to stem canker disease, e.i. Hutton only yielded 18.4 bu./a. One line F77-1797 yielded 3 bu./a. better than did Cobb, and it is being increased for release in 1983. -5- Table 1.

DATA RECORDED The yield of a crop is the primary factor of production when profits are to be maximized. Other characteristics which are im- portant are plant height, height of lowest pod, maturity, lodging, and size and quality of seed. Yield of soybeans was determined by harvesting the two center rows of each plot with a small plot combine. Plot yields were ad- justed to 13% moisture and converted to bushels (60 pounds) per acre. First bloom was taken as the date when there was one flower at any node on 10% of the plants. Maturity was rated as the date when the pods were dry and most of the leaves had dropped. Under most conditions, the stems were also dry. Harvest date was approximately 7-10 days later than maturity date. Lodging was based on a scale of 1 to 5 according to the fol- lowing criteria, see page 8 for illustrations: 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 (approxi- mately 450) or 25 to 50% of the plants down. 4 - either all plants leaning (more than 450) or 50 to 80% of the plants down. 5 - all plants down. -6- Shattering ratings were based on shattering of the border rows 14 days after maturity. The visual estimates were rated on a scale of 1 to 5 as follows: 1 - no shattering. 2 - 1 to 3% shattering. 3 - 4 to 8% shattering. 4 - 9 to 19% shattering. 5 - 20% or more shattering. 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 g per 100 seeds. Small, medium, and large seed size will be 8-12, 13-16, and 17-20 g/100 seed, respectively, and will have approximately 5,700 to 3,800, 3,500 to 2,800, and 2,700 to 2,300 seeds per pound, respectively., 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 due to late harvesting, and to excess rain. Purple stain ratings were given to seed samples on a scale of 1 to 5 as follows: 1 - no purple staining. 2 - 1 to 3% purple staining. 3- 4 to 8% purple staining. 4 - 9 to 19% purple staining. 5 - 20% or more staining. -7- " x Z .k Y.'
