The purpose of this study is to evaluate various soybean planting populations, planted in 30 in. rows, to determine the Economic Optimum Seeding Rate (EOSR).

2019 Minnesota Soybean Population Study - 30 in. Rows

The highest ROI in 2019 was at the 125,000 seeding rate, but it was virtually the same as the 150,000 rate. The two-year data favors the 150,000 seeds/A. planting population.
