More Reasons to Strive for Uniform Stands
Uneven emergence, skips, doubles, and uneven spacing all reduce corn yield potential. The later a plant emerges relative to the plants next to it, the less that plant will contribute to overall yield. Those plants tend to stay behind throughout the season.
Plants that are one or two leaf-stages behind in development as compared to neighboring plants are unable to compete for resources effectively.
The picture shows the resulting reduced ear size on those late-emerging plants and proves the subsequent yield reduction. The goal is to have evenly spaced plants in the best position to capture available sunlight, optimizing photosynthesis and your yields and profitability.
