Data from a field experiment on Real Time Nitrogen Management (RTNM) in rice revealed that variety Gobinda produced significantly the highest grain yield of 49.6 q ha−1 associated with long panicle (26.75 cm) bearing significantly the maximum number of filled grains panicle−1 (156.78) producing highest net return (Rs.33214.71), B-C ratio (1.83) and return per rupee invested (0.83). Application of nitrogen based on LCC threshold value 4 produced significantly the highest grain (52.6 q ha−1), straw yield (64.4 q ha−1), number of EBT m-2 (403.71), panicle length (25.43 cm) and 148.94 filled grain panicle−1. Variety x RTNM interaction was significant and variety Naveen and Gobinda produced significantly the highest yield of 55.4 and 58.2 q ha−1 at recommended dose of nitrogen whereas, Lalat and Hiranmayee responded to LCC threshold value 4 (N4) with grain yield of 50.4 and 52.1 q ha−1, respectively.
