Study Findings:
Based on the stand count heat map of an Illinois soybean field, a replant prescription was created with a final stand goal of 150,000 plants/A. Straight rate blocks of 100,000 seeds/A were replicated and placed within the prescription. This allowed them to compare the prescription to the grower’s normal replant population. Variable replant rates ranged from 44,000 to 136,000 seeds/acre, tailored to initial stand counts.
Minor yield differences were observed, but certain rates showed notable improvements. Overall, the variable rate area had ~2.5% higher yield and ~4.5% less seed was used as compared to the 100,000 seed/acre blocks.
Data-driven decisions in replanting can lead to better resource utilization and cost savings.
