Two corn plots (short season, 102-day, and normal season, 111-day corn) were serially harvested to evaluate nutrient, digestibility, and yield change over the duration from half-milk line through black layer. Digestibility of the corn plant decreased as corn plant maturity and NDF content increased. The lower leaf in the normal season plot decreased in digestibility, but did not change in the short season plot. Little change was observed in the digestibility of the internodes across time. The NDF content of the upper plant increased in both plots. The internodes increased in NDF content across time in both plots. The results of this study suggest there is a delicate balance between plant maturity, nutrient content, and yield.
