A field experiment was conducted with a hybrid rice variety (CoRH2) under three irrigation regimes and five nitrogen management practices during rabi season of 1999. Irrigation to 5 cm depth on the day and one day after disappearance of ponded water did not show significant variation as expressed in terms of number of spikelets, filled grains and yield. Application of recommended dose of nitrogen at the rate of 17, 33, 33 and 17 per cent at 7 days after transplanting (DAT), 21 DAT, panicle initiation and first flowering alongwith green manure recorded significantly higher yield of rice compared to other nitrogen management practices.
