Plant Soybean Early to Increase Yield: New research shows that early planting does increase soybean yield, but can vary by year and cultivar choice

摘要

Madison, Wisconsin (February 2, 2009)--Over the past decade, two-thirds of Indiana growers have shifted to planting their soybean crop earlier because they believe that earlier planting increases yield. Planting date is probably one of the most important yet least expensive management decisions that significantly affects soybean yield. Few scientists, however, have studied the effect of early-planting dates on soybean yield components and the impact of early planting on seed composition.
