Abstract: Water is the most abundant material in a growing plant. It comprises of 80 percent or more of the plant weight. It is the main carrier for food materials and other substances transporting inside the plant body. The reactions of plants to water stress differ significantly at various structural levels depending upon intensity and duration of stresses as well as plant species and its stage of growth. The present review highlights the effect of drought stress on rice crop productivity. Plant growth and productivity of rice is adversely affected by various biotic and abiotic stress factors. Water deficit is one of the major abiotic stresses, which adversely affects crop growth and yield. Water stress is a limiting factor in agriculture production by preventing a crop from reaching the genetically determined theoretical maximum yield. In plants, a better understanding of the morphological and physiological basis of changes in water stress resistance could be used to select or create new varieties of crops to obtain a better performance under water stress conditions.
