2021 Orthman Research Yield Book


High Plains FFA Orthman teams with High Plains Community Schools FFA to help students gain agronomic knowledge and research experiences throughout the growing season on a local farmers ground. This year the crop was soybeans and the trial was to compare yields at five different planting populations. Soybeans were planted at 60,000 seeds/ac, 80,000 seeds/ac, 100,000 seeds/ac, 120,000 seeds/ac and 150,000 seeds/ac. One round or 32 rows of each population were planted and harvested to compare yields and ROI of the recommended population of 150,000 seeds/ac to reduced seeding rates under high management.
