Abstract: A field experiment was conducted on clayey soil at the Instructional Farm, Junagadh Agricultural University, Junagadh (Gujarat) during the summer season of 2015 in a factorial randomized block design with three replications, comprised with three nitrogen levels (90, 120 and 150 kg ha-1) and three application schedules (50% as basal + 50% as top dressing, 40% as basal + 60% as top dressing and 30% as basal + 70% as top dressing). Nitrogen applied as basal at time of sowing and as top dressing in two equal splits at 30 & 45 DAS. Application of nitrogen up to 120 kg ha-1 remarkably increased plant height, number of total tillers and dry matter per plant at 30 & 45 DAS and at harvest, nitrogen content in plant at 30 & 45 DAS and number of effective tillers per plant, length and girth of earhead, test weight at harvest and consequently recorded significantly higher grain and stover yield along with protein content of grain, nitrogen content and uptake by grain and stover as well as obtained higher net return and B: C ratio as compared to 90 kg ha-1. Application schedules of nitrogen 30% as basal at sowing + 70% as top dressing in two equal splits at 30 & 45 DAS significantly enhanced plant height and number of total tillers per plant at 30 & 45 DAS and at harvest and number of effective tillers per plant, length and girth of earhead, test weight at harvest and subsequently recorded higher grain and stover yield along with protein content of grain and nitrogen content and uptake by grain and stover as well as obtained higher net return and B:C ratio in comparison to 50% as basal + 50% as top dressing. Interaction effect of nitrogen levels and application schedules was found significant in respect of number of total tillers per plant at 30 DAS, protein and nitrogen content in grain and they were significantly higher under application of 120 kg N ha-1 with 30% basal at sowing + 70% top dressing in two equal splits at 30 & 45 DAS as compared to rest of treatment combinations.
