Ear Declination Prior to Corn Maturity
Something went wrong. Please try again later...
By Dairyland Seed Agronomy Team
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.
