Transcription

1 Information DEPARTMENT OF PLANT SCIENCE & LANDSCAPE ARCHITECTURE COLLEGE PARK, MD (301) Agronomy Facts No. 32 MARYLAND SOYBEAN VARIETY TESTS Maryland soybean variety tests are conducted each year by the Maryland Agricultural Experiment Station, Department of Plant Science and Landscape Architecture, to provide soybean growers with the latest information on agronomic performance of soybean varieties. Varieties are tested by maturity group as designated by the releasing organization. Varieties of Maturity Groups 3, 4, and 5 are included in the tests because they are best adapted for production in Maryland. Late maturing varieties in Maturity Group 4 (relative maturities of 4.6 to 4.9) were evaluated separately from the other varieties in Maturity Group 4 and are listed as 4s in the data tables. All entries in the test are tolerant to Roundup herbicide. Entries with STS in their names also have tolerance to the sulfonylurea herbicides. The brands and suppliers of the entries in this year s test are listed in Table 1. The Maryland tests are designed to evaluate varieties at several planting dates and on various soil types within the soybean production areas of the state. Recommended cultural practices were followed in the establishment of each test. Tillage, row spacing, seeding rates, and plot length varied between tests and locations as shown in Table 2. Seed yield was determined on center rows of each plot, and plots were trimmed to a uniform length just prior to harvest. Each plot was replicated three times in each test and location. Seed moisture was determined on each plot and seed yield was adjusted to a 13% moisture level. Plant height and lodging were determined at maturity when 95% of the pods on each variety had attained their mature color. The growing season was generally one of favorable temperatures and soil moisture in most areas of the state. Rainfall during June and July was above average at Quantico and Queenstown. The wet soil conditions resulted in the appearance of Phytophthora disease symptoms on several entries in both the full-season and double-crop tests at Quantico. Timely rainfall across the state in September and October resulted in good yields for both full-season and double-crop plantings. Scattered frost across the state in late October impacted the maturity date for the Maturity Group 5 varieties in the double-crop tests at Quantico and Queenstown. Monthly rainfall amounts for May through October for the test locations are shown in Table 3. Results of the tests are reported in Tables 4-9. In each of these tables, varieties within maturity groups are listed in order of yield, highest to lowest. The highest overall test location mean yields were at Keedysville for the full-season tests (63.6 Bu/A) and Quantico for the double-crop tests (61.9 Bu/A). A least significant difference (LSD) value is reported for each maturity group in every test where statistically significant differences in plant characteristics were observed among varieties. This number is a statistical test calculated at the 20 percent probability level to aid in comparing the differences among varieties in a maturity group. When two varieties are compared for a plant characteristic and the difference between them is greater than the calculated LSD value, the varieties are judged to be significantly different for that specific characteristic. The ns designation indicates that there are no statistically significant differences among the varieties in that maturity group for that specific characteristic. The coefficient of variation (CV) is a relative measure of the variation and is an indicator of the degree of precision for a particular test. For these soybean variety tests, CV values below 15% are an indication that the precision of the test is good in distinguishing differences in seed yield between varieties.

2 The performance of a variety for several years or at several locations in the same year gives a better indication of its yield potential and agronomic characteristics than do data from a single year or location. As an aid in assessing the performance of individual varieties in the test, a relative yield value was calculated. Table 10 summarizes the relative yields of the varieties by expressing their yields as a percentage of the mean yield of all varieties in that maturity group at each location. Therefore, a variety with a relative yield that is consistently greater than 100 is a variety that consistently yields higher than the mean yield of all varieties in that maturity group. In Table 10, the relative yields of those varieties with an asterisk are not statistically different from the highest yielding variety in that maturity group in those tests where a significant difference between varieties was observed in the statistical analyses. Two-year average yields of varieties previously entered in the 2012 tests are shown in the data tables. The 2012 location average yield for each maturity group and the 2012 LSD value are included in the data tables to compare variety yield differences in both years. The multiple-year data provide additional information on a variety s yielding ability. The information provided here should be used as a guide and growers should select a variety with great care based on personal experience as well as other available information. Prepared by: W.J.

Actual yield can be obtained by converting the relative yield to a decimal percentage and multiplying this value by the location/group mean yield. A variety with a relative yield that is consistently greater than 100 is a variety that consistently yields higher than the mean yield of all of those varieties in that maturity group. 21
