Field experiments were conducted during both the wet (June-November) and dry (January-May) seasons to study the effects of N fertilization and water management practices on yield, grain quality and milling out-turn of rice (Oryza sativa L.). Among varieties, Jaya not only had the greatest yield, it also responded the most to N fertilization. Pusa 2-21 had the poorest grain yields; however, it had the highest protein content, grain hardness, and head yield. Significant improvement in yield, yield attributes, protein content, grain hardness, and head yield was obtained from N applications up to 90 kg N/ha during the wet season and up to 120 kg N/ha during the dry season. Among water management practices, continuous or phasic submergence of the paddy field proved to be more beneficial to the crop than cyclic submergence. However, the beneficial effect of submergence on grain yield was observed only during the dry season.
