Field experiment was laid out to study the effect of nitrogen levels and plant population on maize. Maximum leaf area plant^-1 (2757 cm²), leaf area index (2.16), grains ear^-1 (548), thousand grain weight (258 g) and grain yield (2673 kg ha^-1) were recorded with application of 210 kg nitrogen ha^-1 which was statistically similar to 180 and 150 kg nitrogen ha^-1. Higher biological yield (7189 kg ha^-1) was recorded from 150 kg nitrogen ha^-1 which was similar to 210 kg nitrogen ha^-1. Maximum number of leaves plant^-1 (10.45) was recorded for plant population of 80000 plants ha^-1. Higher leaf area plant^-1 (2585 cm²) and leaf area index (2.59) were recorded for 65000 plants ha^-1 which was statistically at par with 80000 plants ha^-1. Higher grains ear^-1 (515) and thousand grain weight (252 g) were recorded from 65000 plants ha^-1 which was similar to 80000 plants ha^-1. Plant population of 95000 plants ha^-1 produced maximum biological yield (7276 kg ha^-1) while plant population of 80000 plants ha^-1 produced maximum grain yield (2551 kg ha^-1) and harvest index (35.95%). It is concluded from the study that application of 150 kg nitrogen ha^-1 produced maximum grain yield and plant population of 80000 plants ha^-1 produced higher grain yield.
