The main plot treatments consisted of two seeding date (25 November and 10 December) while sub plot treatments consisted of four levels of nitrogen (0, 40, 80 and 120 kg N ha-1) and two seed rates (125 and 150 kg ha-1). The soil of the experimental plot was sandy loan in texture, having 210.0, 27.5 and 149.0 kg ha-1 available N, P and K respectively and acidic in reaction (PH 6). The results revealed that higher seed rate (150 kg ha-1) gave more number of plants but it did not influence on yield. Nitrogen levels significantly influenced the growth and yield attributing characters. Application of 120 kg N ha-1 was found significantly superior to 0, 40 and 80 kg N ha-1 on yield and yield attributing characters. Seeding on November 25 produced 22.47 percent higher grain yield than late seeding (26.7 q ha-1). Application of 120 kg N ha-1 give higher grain yield (38.8 q ha-1), straw yield (72.75 q ha-1) net return (Rs. 12,750 ha-1) and net benefit/cost ratio of Rs. 1.88 on each rupee of investment as compared to the rest of the levels. Correlation between grain yield and yield attributes was found highly significant and positive. Variation in seed rate did not show marked effect on grain yield and monetary productivity of wheat crop. Interaction between seeding date, nitrogen levels and seed rates were not found significant in any character studied.EnglishThesis
