Utah agriculture producers have become interested in interseeding cover crops as a companion crop in corn. Although interseeding has been successful in Midwest states, little research exists on interseeding cover crops in the Intermountain West. To address this need, a state-wide research trial was conducted that focused on identifying the most effective planting times (corn growth stage) to interseed cover crops by measuring corn silage yield and quality. No effect (P > 0.05) on corn silage yield or quality was found due o cover crop inerseeding time. However from a corn management perspective the V4 - V6 period became an ideal planting time due to the various timelines of managing corn in the intermountain west.
