COLUMBUS, Ohio â Like the Ohio Corn Performance Test, results of the 2002 Ohio Soybean Performance Trials are singing the same tune. Those varieties that yielded well under a wet spring and dry summer can tolerate a lot of stress. The test results are a bright spot in an otherwise dismal growing season for some soybean growers. According to the U.S. Department of Agriculture, soybean yields in Ohio are averaging 32 bushels per acre, compared to 41 bushels per acre harvested last year. Ohio State University Extension agronomists tested 203 soybean varieties at six locations throughout Ohio. Yields ranged anywhere from 30 bushels per acre to 60 bushels per acre, with yields averaging 53 bushels per acre in northern Ohio, 41 bushels per acre in central Ohio and 57 bushels per acre in southern Ohio. The tests measure such characteristics as yield, maturity, insect and disease tolerance, oil and protein content, plant height, seed size and lodging potential. âWe got lucky in that we got some good rains at some important times, resulting in good yields despite the variable weather,â said Jim Beuerlein, an Ohio State Extension agronomist. Despite the low state average yields, which Beuerlein said are running 70-75 percent of normal, soybeans still performed better than the corn crop. âMuch of that has to do with the soybeanâs growth habit. Corn is a determinant crop and it basically goes through these certain periods that last a few days. If conditions arenât good, then you wonât have a good crop,â said Beuerlein. âWith soybeans, those stages, instead of lasting a few days, last a few weeks. So soybeans tend to tolerate short periods of adverse weather much better than corn.â Despite the favorable yield results from the soybean performance trials, there is one shortcoming growers should keep in mind when choosing varieties to plant next year: lack of insect and disease development. âWe had very little disease and almost no insect problems because of the dry weather, and thatâs very unusual,â said Beuerlein. âSo varieties that yielded well may not yield well in a year with a lot of disease and insects. One thing that growers need to keep in mind is that this was a very atypical year. The differences and conclusions we draw will only be valid for years that are similar to this one.â For more information on the Ohio Soybean Performance Trials, log on to http://www.ag.ohio-state.edu/~perf/, or contact Beuerlein at (614) 292-9080 or email@example.com.
