PERFORMANCE OF SOYBEAN VARIETIES IN ALABAMA, 1993 K.M. Glass and D.I. Bransby' INTRODUCTION Soybean variety tests are conducted, annually by the Al abama Agri cultural Experiment Station. The 7 locations used represent the major soil and These locations are divided into logical soybean climatic regions of Alabama. growing regions. Region Northern Central Southern Black Belt Gulf Coast The regions and locations are: Location Belle Mina, Crossville Prattvil11e Brewton, Monroeville Marion Junction (2 soils) Fairhope EXPERIMENTAL PROCEDURES The standard tests were designed as a randomized complete block with four replications. Plot size was four 24- to 36-inch rows 20 feet long. Seeding rate Sixteen feet of the middle two rows were harvested for yield. was 10 viable seeds per foot of row. The early date test was arranged in incomplete lattice square design with four replications. Data were collected on seed yield, moisture, lodging, shattering, plant height, and maturity date. Plot yields were adjusted to 13 percent moisture 2 - either all plants leaning slightly (less than 45") or a few plants down. 3 - either all plants leaning moderately (approximately 45") or 25 to 50 percent of the plants down. 4 - either all plants leaning more than 45" or 50 to 80 percent of the plants down. 5 - more than 80 percent of the plants down. Shattering was rated on a scale of 1 to 5 based on performance of the border row 14 days after maturity. A rating of 1 indicates no shattering, a rating of 3 indicates a 4 to 8 percent shattering, and a rating of 5 is 20 percent or more shattering. Plant height was determined by measuring from the Maturity date was the day 95 Harvest was approximately 7 to ground to the top of the plant at maturity. percent of the pods reached mature pod color. 10 days later. SEASONAL CONDITIONS Rainfall (Table 3) in April and May 1993 was such that planting dates for the standard tests in northern Alabama and Marion Junction in central Alabama were delayed. growth. All other standard tests were planted for optimum The normal planting dates for full season plantings in the regular tests are the first week in May, May 15-25, and May 25 to June 5 for northern, central, and southern Alabama locations, respectively. COMPARING VARIETIES To aid in determining real yield differences, a statistical analysis of variance is performed on the data from each location. The L.S.D. (least significant difference) and C.V. (coefficient of variation) are given for each location's 1993 test, and for the location's or region's 2- and 3-year averages. The difference in yield of two varieties must exceed the L.S.D. -6- value for one variety to be considered superior to the others in yield in that particular test. The C.V. is a measure of the variability in an experiment. An increase in its value indicates an increase in the unexplained variability. Since the performance of varieties varies with location and year, longterm averages from several locations are more reliable than 1-year performance. Three-year regional averages are considered a reliable evaluation of the relative performance of varieties. -7- ACKNOWLEDGMENTS Appreciation is expressed to the following station superintendents and their staffs.
