Irrigation schedule in producing quality basmati rice (Oryza sativa)

Schedule of irrigation application after 2 days of infiltration of ponded w ater produced significantly higher grain yield over that of 4 days after in filtration of ponded water. The irrigation scheduled at 2 days after infilt ration of water though having higher water expense resulted in greater wate r expense efficiency. Significantly improved rice (Oryza sativa L.) recover y and protein content of polished kernels and lowering of alkali splitting score were observed under the treatment of frequent irrigation application. Withdrawal of irrigation at 21 days after 50% flowering had significantly higher grain yield, water expense efficiency, hulled, milled and head rice recoveries and protein content of basmati rice than at withdrawal of irriga tion at 7 or 14 days after 50% flowering.
