Partitioning of N content in different plant parts individually and on a whole-plant basis of Pioneer 3893 and Pioneer 38W36 Bt maize hybrids at physiological maturity, averaged across two N treatments for 2 yr. The bars labeled with different letters within each component are significantly different (P 0.05).

Effect of N treatment on the partitioning of dry matter in a maize plant at physiological maturity stage averaged across two hybrids for 2 yr. The bars labeled with different letters within each component are significantly different (P 0.05). The N treatments are N0 = 0 kg N ha–1 and N150 = 150 kg N ha–1 with 5% 15N2–NH4NO3.

Effect of N treatment on N concentration in a maize plant at physiological maturity stage averaged across two hybrids for 2 yr. The bars labeled with different letters within each component are significantly different (P 0.05). Nitrogen treatments are N0 = 0 kg N ha–1 and N150 = 150 kg N ha–1 with 5% 15N2–NH4NO3.

The bars labeled with different letters within each component are significantly different (P < 0.05). Nitrogen treatments are N0 = 0 kg N ha–1 and N150 = 150 kg N ha–1 with 5% 15N2–NH4NO3.
