Abstract

Soybean yields often increase, up to a point, with increasing plant population. However, soybean yield responses to plant population are generally small and often inconsistent. In general, increasing plant populations increase plant height and result in greater yield losses from lodging. Soybean seed prices have increased tremendously over the last couple of years. Our hypothesis is that seed cost can be reduced in replanted fields. The objective of this experiment was to determine the optimum plant population across different planting dates in northeast Iowa.
