SOYBEAN VARIETY YIELD TEST IN 2000
Bill Cox
Department of Crop & Soil Sciences
The annual testing of Roundup Ready and non-Roundup Ready varieties and experimental lines of soybeans was conducted at four locations in New York State in 2000. At each location we planted all entries of the same maturity Group in a separate test. Also, Roundup Ready, non-Roundup Ready, and food grade varieties were evaluated in separate tests. Each individual plot at Canton and Chazy consisted of four 20-foot rows spaced 14 inches apart. There were four replications of each entry at each location. We used preemergence applications of herbicides in the non-Roundup Ready tests, whereas we relied exclusively on 3 pints/acre of Roundup Ultra for weed control in the Roundup Ready tests.
During the season, notes on development were made at intervals. Yields were determined by harvesting a measured section of the center rows in each plot. All plots were harvested with a Hege plot combine.
