| Abstract: |
Attempts have been made to summarise and highlight research findings on the seed production of maize inbred through the use of different levels of nitrogen to the crop planted at varying densities. Series of experiments on NML-1 inbred were conducted in acidic soil (5.1 pH) during the year 2003 and 2004 at the farmland of NMRP, Rampur to evaluate the effect of nitrogen and plant densities on the grain production of maize inbred. A factorial RCBD with three replications was employed in the experiment for the two consecutive years. Nitrogen at 60, 120 and 180 kg N /ha was applied and plant densities at 55,555; 66,666 and 83,383 plants/ ha were maintained in the experiment. Crop growth and yield parameters were analyzed statistically. The results revealed that crop growth (plant and ear height) was observed to be non-significant by the effect of the crop density; however the effect of density and nitrogen on stover production was observed to be significantly affected. The highest stover yield (7.7 t / ha) was produced by the crop planted at the density of 66,666 plants/ha when the crop was supplied with 180 kg nitrogen /ha. The highest number of kernels per kernel row (24.3 kernels / row) was observed at this level of N and plant densities. The effect of nitrogen and density on thousand grain weight was also found to be significant. Two-years mean result revealed that highest seed yield (2.85 t/ha) was obtained when the crop was supplied with 180 kg nitrogen /ha and plant densities at 66,666 plants ha. Increased seed yield of NML-1 inbred could be obtained with increasing rate of nitrogen application upto the density of 83,383 plants/ ha.
