Requirement of nitrogen by maize crop depends on the plant population. The quantity of fertilizer- N applied to the maize crop determines the yield increase or decrease and hence, profitability of the crop. To evaluate the effects of nitrogen levels (60, 90 and 120 kg N/ha) on the maize planted at varying densities (55,555; 66,666 and 83,383 plants/ha), an experiment was carried out for two consecutive years (2006 and 2007) in the farmland of National Maize Research Program, Rampur in a RCB design with three replications. A constant dose of manures and fertilizers at 10 tons of compost and 40: 30 kg/ha of P2O5 and K2O was applied basally in all the experimental plots………………..
