Data on thousand grain weight of maize as affected by nitrogen and planting density are presented in Table 13. Analysis of the data revealed significant effect of nitrogen levels and planting density on thousand grain weight. Interaction of nitrogen and planting density was nonsignificant. Maximum thousand grain weight of 259 g was recorded from 210 kg N ha-1 which is statistically at par with 180 and 150 kg N ha-1 with thousand grain weights of 258 and 250 g, respectively. Thousand grain weights decreased with increasing planting density. Maximum thousand grain weight of 253 g was recorded from lowest plant density of 65000 plants ha-1 which is at par with 80000 plants ha-1 with thousand grain weight of 250 g. Minimum thousand grain weight of 242 g was recorded from the highest planting density of 95000 plants ha-1.
