A field investigation was conducted during the kharif season of 2014 to optimize N doses and planting densities for enhanced growth and yield performance of maize under rainfed conditions of Nagaland. Application of N @ 80 kg/ha resulted in higher N uptake and enhanced growth of maize ultimately expressing superior yield attributes and registering the highest grain and stover yields of 3518.5 and 6976.01 kg/ha respectively. Maintaining a planting density of 55, 555 plants/ha at a spacing of 60 cm x 30 cm was found to provide optimum crop stand in maize resulting in higher N uptake and favourable growth consequently recording better yield attributes and maximum grain yield of 2941.66 kg/ha. However, higher planting density of 74, 074 plants/ha at a spacing of 45 cm x 30 cm was found to be more effective for higher stover yields up to 6772.63 kg/ha.
