Growers like to have hybrids with high yield potential, excellent disease tolerance, great standability, faster dry down and lower grain moisture at harvest. Well there seem to be a contradiction here. Hybrids that live longer are not going to die earlier and dry fast. Management decisions such as planting date, plant population, amount of nitrogen used, and use of foliar fungicides all affect the rate of dry down and grain moisture at harvest.
• Corn breeders have to constantly compromise to find hybrids with the right combinations that will produce the highest income for the growers. What are the agronomic and genetic characteristics of corn hybrids that affect rate of dry down?
• Hybrid relative maturity, thickness of pericarp or skin of the kernel, ear angle after maturity can all affect dry down rate. Hybrids with thinner cobs tend to lose moisture faster.
• As corn matures, moisture is lost through cob and ear shank, exposed ear tips and husks.… Continue readingRead More »
