Ear Declination Prior to Corn Maturity

BY Dairyland Seed Agronomy Team
2024 Corn In Season

Ear declination in corn prior to maturity is most commonly associated with late-season drought stress, which causes a loss of cell turgidity and collapse of the ear shank. The point of failure in the shank is often severely pinched, which can restrict the flow of sugars into the ear necessary to complete kernel fill. If the flow of sugars into the ear drops low enough, it can trigger premature black layer formation and an early end to grain fill.
