Twenty corn hybrids were grown under
irrigation and harvested at 90 % of the kernel
milk line. Hybrid had a significant effect on
plant height, whole-plant dry matter (DM) and
DM yield, grain yield, stover yield, and plant
part proportions. The highest whole-plant DM
(45.9%) was for Cargill 7997, whereas the
lowest was for Cargill 4327 (30.1%). Cargill
8427 and Pioneer 3245 had the highest wholeplant
DM and grain yields, whereas Cargill
4327 was lowest. Grain yield and the percentage
of grain in the whole-plant DM increased
as the plant height increased.
