Performance of Soybean Varieties in Alabama, 1998
K. M. Glass and C. D. Monks1

INTRODUCTION
Soybean variety tests are conducted annually by the Alabama Agricultural Experiment Station. The eight locations used represent the major soil and climatic regions of Alabama. These locations are divided into logical soybeangrowing regions. The regions and locations are as follows: Northern (Belle Mina and Crossville), Central (Prattville and Shorter), Southern (Brewton, and Monroeville), Black Belt (Marion Junction–two soils), and Gulf Coast (Fairhope).

EXPERIMENTAL PROCEDURES
The standard tests were designed as a randomized complete block with four replications. Plot size was four 30to 36-inch rows 20 feet long. Sixteen feet of the middle two rows were harvested for yield. Seeding rate was 10 viable seeds per foot of row. The early planted test at Brewton was arranged in an 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 and converted to bushels (60 pounds) per acre. Lodging was scored on a scale of 1 to 5 as follows: 1–almost all plants erect; 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 percentof 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 rows 14 days after maturity. A rating of 1 indicated no shattering, a rating of 3 indicated a 4 to 8 percent shattering, and a rating of 5 meant 20 percent or more shattering. Plant height was determined by measuring from the ground to the top of the plant at maturity. Maturity date was the day 95 percent of the pods reached mature pod color. Harvest was approximately 7 to 10 days later.

SEASONAL CONDITIONS
Rainfall for 1998 is shown in Table 3. Most standard tests were planted late due to the lack of moisture.The normal planting dates for full season plantings in the regular tests are the first week in May, May 15 to 25, and May 25 to June 5 for northern, central, and southern Alabama locations, respectively. At Fairhope, Hurricane Georges blew down plants and removed leaves on most varieties. Since all varieties were severely affected, no lodging ratings were taken.

COMPARING VARIETIES
To help determine 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 1998 test, and for the location’s or region’s two- and three-year averages. The difference in yield of two varieties must exceed the L.S.D. value for one variety to be considered superior to 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, long-term averages from several locations are more reliable than one-year performance. Three-year regional averages are considered a reliable evaluation of the relative performance of varieties.
