Corn Replant Decisions

When the final stand of corn achieved from the initial planting date is lower than desired, whether or not to replant becomes an issue. The major decision facing the corn producer is whether the original stand or the replanted stand (often at an optimum stand, but planted at a later than desire date) would be the most profitable. Begin by determining the surviving stand from the original planting, assess the health of surviving plants, and arrive at a yield expectation. This yield expectation is compared with that for a full stand planted on a potential replant date. Factors such as replant costs, stand uniformity, hybrid, seed availability, risk of getting a stand from a replant, seasonal differences, replant crop choice, and pest management issues can all influence the replant decision.
