Experiments conducted for several cropping seasons on the montmorillonitic Maahas clay soil at the IRRI farm demonstrate that continual flooding is not essential for high grain yield but flooded rice can tolerate at least 15cmif the improved varieties are grown. Tall varieties like H-4 has less adaptability under wide range of water management conditions than semidwarfs like IR8. With adequate water supply, 5 to 7 cm of water is desirable on most soils for best weed and insect control with granular chemicals, forhigh nutrient availability, and for minimum losses of nutrients from fertilizer and soil. If rainfall does not provide supplemental water, irrigation intervalslonger than 8 days reduce grain yield under a rotational irrigation system. Varieties like IR5 that have a long growth duration were least sensitive to moisture stress imposed by long irrigation intervals. This is because IR5 will generally recover from high moisture stress for a short period or low moisture stress for a long period. An experiment with IR20 indicates that the furrow irrigation of nonpuddled soil does not provide more efficient water use in rice compared with rice grown on puddled lowland soil.
