dc.description.abstractThe experiment was conducted during the 1991 rainy season, at the Institute for Agricultural Research Farm Samaru, to investigate the response of popcorn to different plant densities and nitrogen levels. Treatments consisted of all possible combinations of three plant densities; 53, 333, 71 ,111, and 106, 666 plants /ha and four nitrogen levels; 0, 50, 100, and 150 kg/ha. These 12 treatments were laid out in a randomised complete block design replicated four times. Increased plant density significantly reduced stand count at 12 WAS, plant height at 12 WAS and significantly increased cob yield per hectare, and the total grain yield per hectare. Increased nitrogen levels significantly increased most of the growth and yield characters except the number of grains per cob and 100 seed weight. A combination of 100 kg IM/ha and 71,111 plants per hectare gave significantly higher crop yield than any other treatment combination. Optimum N rate was calculated to be 137 kg N/ha using a regression modelen_US
