Abstract: The field experiment was conducted during the two consecutive kharif and rabi seasons of 2012-13 and 2013-14 on sandy-clay-loam soil at Varanasi to study the assessment of nutrient management options under different methods of rice (Oryza sativa L.) cultivation and their carry-over effect on succeeding wheat (Triticum aestivum L.). System of rice intensification (SRI) exhibited their superiority in terms of higher rice yield (6530 kg/ha), system yield (9942 kg/ha), system productivity (37.2 kg/ha/day) and profitability (₹ 348 ha/day) than normal transplanted rice which were left over higher residual effect and led to produced higher yield attributes and yield of wheat. Rice hybrid Arize-6444 was found more productive in terms of biologically and economically with producing higher yield, R-W system yield (9802 kg/ha), system productivity (36.7 kg/ha/day) and profitability (₹ 332 ha/day) over PHB-71. Incorporation of 50% RDN + 50% N through FYM + Azospirillum recorded significantly higher rice yield (6942 kg/ha), R-W system yield (10734 kg/ha), system productivity (40.2 kg/ha/day) and profitability (₹ 374 ha/day). Residual effect of preceding experimental variables particularly normal transplanting, hybrid ‘PHB-71’ and application of 50% RDN + 50% N through FYM + Azospirillum produced higher yield (2979 kg/ha) of wheat.
