Abstract
Deciding whether to replant a sparse stand is one of the more difficult decisions a corn or soybean grower will face. The difficulty of this decision stems from the difficulty of predicting how the effectiveness of replanting will be affected by the combination of planting date and changing environmental conditions. However difficult, replant decisions are made by at least some Missouri farmers every year. This guide provides a step-by-step procedure for estimating dollar gain or loss from replanting. This procedure involves a careful study of the field in question and an analysis of its yield potential. Follow these steps: 1. Determine the cause of the sparse stand. 2. Determine the stand density and condition of the stand. 3. Determine the yield potential of the sparse stand. 4. Estimate the expected gross revenue from the sparse stand. 5. Estimate the cost to replant. 6. Estimate the yield potential and gross revenue from a replanted stand. 7. Determine whether replanting will pay for itself.William Wiebold (Extension Professor, Division of Plant Sciences), Raymond Massey (Extension Professor, Department of Agricultural and Applied Economics and Commercial Agriculture Program)Reviewed November 2018 -- websit
