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.

    As we are in or just getting done with many hunting seasons, asking an Agronomist to pick a Nitrogen (N) rate for your corn crop is akin to a asking a hunter what his or her favorite weapon to hunt with is. The answer in both instances is probably “well it depends.” As an Agronomist, before recommending a nitrogen rate, I typically ask several questions. It’s often said that the number of questions I might ask is comparable to the number of inquiries new parents make when consulting a physician about their child. Before suggesting an N rate, I have considered the following background information and questions:
