The purpose of this study is to evaluate various soybean plant populations, planted in 15 in. rows to determine the Economic Optimum Seeding Rate (EOSR).

2017 UT Martin Soybean Population Study - 15 in. Rows

This year, the 125,000 seeds/A. rate had the highest return on investment. However, this planted population was irrigated soybeans so the extra moisture that the irrigation provided allowed for greater pod fill later in the season. We typically recommend an increased planting population as you get later into the season to help supplement node count.
