Flooding of rice fields is a serious problem in the river basins of South and South-East Asia where about 15 Mha of lowland rice cultivation is regularly affected. Flooding creates hypoxic conditions resulting in poor germination and seedling establishment. Flash flooding, where rice plants are completely submerged for 10-15 d during their vegetative stage, causes huge losses. Water stagnation ...
The increased occurrence and severity of drought stress have led to a high yield decline in rice in recent years in drought-affected areas. Drought research at the International Rice Research Institute (IRRI) over the past decade has concentrated on direct selection for grain yield under drought. This approach has led to the successful development and release of 17 high-yielding drought-toleran...
Three varieties of groundnut were used to assess the drought tolerance and high yielding potential. Groundnut (Arachis hypogaea L.) is an important oil seed crop mainly grown under rainfed situation. Erratic rainfall frequent during growth period, yields are generally low conditions. Drought critical stages crucial for loss in yield varieties. But tolerant genotypes may give better due maintena...
