Abstract: An experiment was conducted during the period from April to July 2001 to find out effect of 3 levels of plant population (53000, 66000, 80000 plants ha-1) and 4 levels of nitrogen fertilizer (100, 140, 180 and 220
kg ha-1) in silty clay loam soil. The results showed that the yield and yield attributes characters varied significantly due to the variation in population densities and nitrogen rates. The lower plant population (53000 plants ha-1) produced higher cobs plant-1, cob length, grains cob-1 and 1000-grain weight, but the higher plant population (66000 and 80000 plants ha-1) resulted significantly higher grain yield than lowest plant population. The increasing level of nitrogen improve the yield and yield attributes. Maximum values of yield attributes and that of grain yield were with the 2nd highest level of nitrogen (180 kg N ha-1). The highest grain yield (5.03
t ha-1) was recorded from 80000 plants ha-1 with 180 kg N ha-1.
