Abstract

Effects of wild proso millet interference with irrigated corn were evaluated in Nebraska and Colorado over a 2-yr period. Corn yield reductions ranged from 13 to 22% from a wild proso millet density of 10 plants m–2. As density increased, corn yield reduction could be predicted with a rectangular hyperbola regression model. Ten wild proso millet plants m–2 growing with corn produced 4200 to 6200 seed m–2. Corn yields were reduced 10% at one location if wild proso millet removal was delayed 2 weeks after corn planting. If removal was further delayed until 6 weeks after corn planting, corn yield reductions at the two locations ranged from 16 to 28%.
