Abstrakt: Low moisture tensions during pollination increased yield and during internode elongation increased spikes per plant and kernels per spike. Compared with 60 pounds of N per acre, 240 pounds increased spikes per plant, kernels per spike, and yield. N applications only at planting resulted in increased kernels per spike, kernel weight and yield, but decreased spikes per plant. Later applications in conjunction with planting applications resulted in further increases of spikes per plant and kernel weight.
