Abstract
Studies were conducted to economise the irrigation water in rice cultivation. The water used and the yield obtained in water saving method of irrigation and surface flooding were calculated for six high yielding rice varieties. It was found that submergence was not necessary in the early stages of plant growth. The saving of water by water saving method was upto 49 per cent. After flowering standing water to a depth of 2.5 to 3.5 cm. was necessary.
