A field experiment was conducted during rabi 2011 on popcorn consisting four levels of irrigation (Irrigation at critical growth stages, 0.6, 0.8 and 1.0 IW:CPE ratios) and four levels of nitrogen (80, 100, 120 and 140 kg N ha-1). Growth and yield attributes of popcorn were significantly improved due to irrigation scheduling at 0.8 and 1.0 IW:CPE ratios over lower levels of irrigation. Significantly higher popcorn grain (8.47, 22.00 and 25.09 per cent) and stover (5.31, 19.47 and 26.68 per cent) yields were obtained under 1.0 IW:CPE ratio as compare to 0.8, 0.6 IW:CPE ratios and irrigation at critical growth stages, respectively. The increasing levels of nitrogen significantly improved growth, yield and yields attributes up to 140 kg N ha-1. However, it was remained at par with 120 kg N ha-1. The highest net return of ‘ 74779 ha-1 (BCR = 2.98) were obtained at 1.0 IW:CPE ratio with 120 kg N ha-1. So it is advisable that, for securing higher profit and yield the popcorn should be irrigated at 1.0 IW:CPE ratio with application of 120 kg N ha-1.
