Iowa’s 2012 corn crop races through development stages because of rapid Growing Degree Day (GDD) accumulation (see Table 1 and August 3 ICM News). High minimum daily temperatures largely contributed to the abnormal GDD accumulations. Many wonder and ask how the GDD accumulation rates affect not only maturity but also yield.
