Abstract

Weed populations and yield potentials are spatially distributed in farmer' fields. The objective of this study was to determine if weed stress differentially influenced corn yields in areas of high, medium, and low grain yield potentials. High (20 to 24 plants/m row) and low (6 to 8 plants/m row ) velvetleaf populations were chosen for the study. Corn grain yield was measured in the center, fringe, and outside of the weed infestation. As the yield potential decreased the impact of velvetleaf on grain yields increased. For example, the low velvetleaf infestation reduced yields 50% under low yielding conditions and 10% under high yielding conditions.
