Across Ohio, the corn crop in general is set up for high yields based largely on ample amounts of precipitation and moderate temperatures during most of the 2013 growing season. Lately, rainfall has been at a premium with some areas receiving adequate moisture and others needing a good shower to finish the crop. The questions that remain are, will my corn crop mature and what should I be looking for prior to harvest? This update attempts to address both of those questions.
Overall GDU (heat) accumulation during 2013 is currently below normal across most of Ohio. As a result, corn grain fill, drydown and harvest maturity are delayed. Prevailing weather conditions between now and harvest will dictate how fast field drying will occur versus harvesting at higher moisture and using artificial drying methods for the corn crop. The rule of thumb, based on research conducted at Ohio State University, is that field drying rates of standing corn range from half to three-quarters of a point of moisture per day up until mid-October, and decline to a quarter to half a point until early November.… Continue readingRead More »
