Response of hybrid rice to scheduling of nitrogen and irrigation during dry season

Field experiment were conducted to study the performance of hybrid rice to scheduling of irrigation and nitrogen level. Nitrogen scheduling of 40+20+30+10 percent at basal, active tillering, panicle initiation and flowering reduced the sterility percentage and increased effective tillers and grain yield of hybrid rice. Irrigation, one day after disappearance of water proved as good as continuous submergence for yield components, grain yield and N content in stem and leaf at early stages, flag leaf, grain and straw. The irrigation schedule of one day after disappearance of ponded water required 604 mm less irrigation water than that of maintaining continuous submergence.
