Increase in nitrogen rates significantly increased TDM from 0 up to 120 kg N ha-1 in 2009 and not beyond 80 kg N
ha-1 in 2010 by 59.80 % and 77.73 % respectively. Weight of ears per plant was statistically similar at 40-120 kg N
ha-1 and higher than control in 2009, and significantly higher at 80 kg N ha-1 in 2010 (Table 4). Increasing rates of
N significantly increased the number of kernels per ear up to 80 kg N ha-1 beyond which it decreased in both
seasons
