Ear Declination Prior to Corn Maturity

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.

  • Soybean Harvest Moisture Content, Risk, and Reward
    Looking at a soybean field and knowing what the products will yield, within a bushel or two, takes a special eye and skill. A skill that not everyone possesses, myself included. Conversely, knowing when to start combining soybeans, to get the highest yield and still get the highest moisture possible without being docked, takes skill as well.

  • Insect-Viral Complex
    As a follow up to last weeks soybean aphid article, we are still receiving calls and comments about oddities being observed in relatively new growth even as we begin to see the soybean plant start to naturally senesce. Many of these oddities are notable and can often be confused with or complicated by other disease presence. Viral infections seldom cause significant yield reduction unless pest pressures are extreme or complexed with multiple pathogens. As last season’s very mild winter followed by this season’s varied mix of moisture and temperature created conducive avenues for multiple insects to vector a pathogen(s) to the plant.
