Abstract

An experiment to study the effect of different levels of nitrogen on growth, development, yield and profitability of wheat genotypes in sandy loam soil at Birsa Agricultural University Farm, Ranchi during Rabi season was carried out in split plot design consisting of 3 nitrogen levels viz. 120, 150 and 180 kg/ha in the main plot and 6 genotypes (NW-2026, WH-736, HD-2790, HUW-468, PBW-343 and HD-2733) in the subplots. The results showed that the crop at 150 kg nitrogen/ha had significantly improved grain yield (49.37 quintals/ha), grain production rate (138.93 kg/ha/day), physical productivity (40.76 kg/ha/day) and crop productivity (11.42 kg/ha/day) respectively. kg/ha/day), straw yield (77.12 quintals/ha). Wheat genotype NW-2026 achieved maximum grain yield (51.43 quintals/ha), grain production rate (141.84 kg/ha/day), physical productivity (42.50 kg grain/ha/day). Apart from this, PBW-343 was found to be the second best genotype with grain yield of 48.97 quintals/ha, net return of Rs 25,645/ha and benefit cost ratio of 2.14.
