Grain fill is a critical part of a corn plant’s life, but is often overlooked because it is kind of slow, boring and uneventful to watch. What is actually occurring soon after pollination is utterly amazing considering an acre of corn has to “build” over 11,200 pounds of dry matter to equal 200 bushel of grain yield. Therefore grain fill is anything but boring and is vital for high yields.
Grain fill is the period of corn growth and development between pollination and black layering (or physiological maturity). During grain fill the corn plant is using their leaves to capture sunlight to drive photosynthesis that in turn produces the sugars the plant needs to build yield. The corn plant also uses its roots to acquire moisture and nutrients to build the dry matter. Therefore the more sunlight a corn plant can intercept and the more nutrients and water it can aquire, equates to more optimal grain fill and therefore higher yield potential.… Continue readingRead More »
