Irrigation schedule in producing quality basmati rice (Oryza sativa)

Abstract

Schedule of irrigation application after 2 days of infiltration of ponded water produced significantly higher grain
yield over that of 4 days after infiltration of ponded water. The irrigation scheduled at 2 days after infiltration of water
though having higher water expense resulted in greater water expense efficiency. Significantly improved rice (Oryza
sativa L.) recovery and protein content of polished kernels and lowering of alkali splitting score were observed under
the treatment of frequent irrigation application. With drawal 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 irrigation at 7 or 14 days after 50% flowering.
