Abstract:
Pulses are very crucial in human diet as it is a potent source for protein. These also play significant roles in conservation farming systems and add to food security in the developing countries. Climate change in particular with drought is one of the most important reasons for the adverse effect on its area production and productivity in many regions of the world. The amount of water reduction is directly proportional with yield reduction, but the degree of the impact varies with legume species and the phenological state during which drought occurs. On the whole lentil, groundnut and pigeon pea were found to experience lower drought induced yield reduction as compared to legumes such as cowpea and green gram. Usually yield reduction is greater when legumes experience drought during the period of the reproductive stage as compared to the vegetative stage. In the face of changing climate, our study provides useful information about the physiological base and research information for development of drought resistant legume species to improve alteration and flexibility of agricultural systems in the drought affected regions of the world.
