Abstract
To assess the effect of nitrogen application raws and planting density on the yield of maize cv. "Sunehri" afield experiment was conducted during 19X9. hour nitrogen levels (0. 100, 150 and 200 kg N ha ■) and three planting densities (111 III, H3333 and 66666 plants ha ) with 60 x 15. 60 x 20 and 60 x 25 cm spacings were tried. There was progressive increase in the number of days taken to maturity with increasing levels of nitrogen. Increase in plant population delayed the maturity. Grain yield in all fertilizer treatments increased over control and the increase was in the range of 43.9 to 51.1%. Highest grain yield was recorded in plots fertilized at the rate of 200 kg X ha . Nitrogen application increased the number of grains per cob and cob length. Maximum thousand grain weight was recorded with 200 kg N ha and plant spacing of 60 x 20 and 60 x 25 cm. Higher nutrient gram ratio of 1:20.1 was noted with 100 kg N ha .
