ABSTRACT

A field experiment was conducted during winter seasons of 1996–97 and 1997–98 to study the effect of irrigation (IW:CPE of 1.0, 1.2 and 1.4) and nitrogen (0, 40, 80 and 120 kg/ha) on grain yield response, nutrient content and its uptake rates and other parameters in rajmash. The result revealed that scheduling irrigation at IW/CPE of 1.4 produced the highest mean grain yield (1854 kg/ha). Nitrogen dose of 80 kg/ha was found to be the optimum (1916 kg/ha). The N content in grain decreased, while P and K content increased with increase in frequency of irrigation. Application of N increased the N, P and K content in both grain and straw. The nutrient uptake rate per tonne of grain, nitrogen harvest index (NHI) and crude protein in seed wereless affected by irrigation levels as compared to the rate of N application. The highest NHI (74.0%) was estimated at control, while the highest crude protein in seed (20.3%) was noted at 120 kg N/ha. The partial factor productivity of nitrogen was maximum at IW/CPE of 1.4 (29.9 kg grain/kg N) and with nitrogen level of 40 kg/ha (41.1 kg grain/kg N).
