Early May planting dates better for soybeans
Ohio soybeans planted from May 1 through mid-May resulted in better yields, according to a study by researchers from Ohio State University Extension and the Ohio Agricultural Research and Development Center.
In the study of 2013 and 2014 planting trials at OARDC’s Western Agricultural Research Station near South Charleston, Ohio, soybean yields decreased by 0.6 bushels per acre per day when planted after mid-May, according to Laura Lindsey, a soybean and small grains specialist with OSU Extension.
Those yield results held true if the soil temperatures were 50 degrees or warmer, Lindsey said. However, soybeans planted too early when soil conditions were not adequate resulted in bean leaf beetle defoliation and frost damage.

“There are some exceptions to a yield advantage when planting early, such as if the soils aren’t warm enough or if the fields are too wet,” she said. “In those cases, early planting can be.... (To read more, click the link below):
