The grain yield was reduced by 16-32 per cant in different rice varieties under water- logged conditions. The yield was affected mostly by reduction in panicles per unit area. However, cultivar NC. 1281 showed even an increase in yield under water-logged soil. Water-logging had impaired growth constituents like TDW, LAI and nitrogen uptake. The adoptability of NC. 1281 to water-logged habit was attributed to the production of high dry matter at flowering and its contribution to grain yield.
