Abstract

Corn plots were serially harvested over 2 years to evaluate changes in nutrient content, digestibility, and yield as plants matured from half- milk line through black layer. In yr 1 (2013), short (102 d) and normal (111 d) season hybrids were grown. Year 2 used 111 d and 112 d hybrids. Silage and grain yield increased until black layer. Silage DM increased with maturity to 42% at black layer. Percent NDF in the stover, NDF- digestibility and overall silage TDN increased quadratically as maturity increased. Th ere is a balance between moisture content, nutrient content, and silage yield, as corn plants mature.
