Soybean Planting Recommendations
New Recommendations for Soybean Plant Populations
Studies by Iowa State and the University of Minnesota found that, regardless of row width, harvest plant populations as low as 100,000 plants per acre in Iowa and 110,000 plants per acre in Southern Minnesota have resulted in optimum yields. Typically, a 20-25% stand loss can be expected from planting through harvest. Therefore, under normal planting conditions, 150,000 seeds per acre should be an adequate seeding rate. Higher plant populations of 165,000 to 200,000 seeds per acre at planting are preferred in the Red River Valley, where the growing season is shorter.
