Effect of water stress and its management in vegetable crops: A review article

Climate change is the one of the major problem for low production of most of the vegetable crops worldwide that reducing average yield for most of the vegetable crops. Hostile environmental conditions such as drought, water logging, high saline levels, extreme temperatures, nutrients and other factors pose serious problems in production of vegetables. Among this water stress adversely affect on functioning of stomata, germination, growth reduction, premature senescence and reduce productivity. Water stress may be of two types i.e. drought and water logging. Mitigation of water stress is very important to reduce the yield loss. The water stress can be mitigating by mulching, use of Plant Growth Regulators, antitranspirants, hydrogel, grafting techniques and use of resistant varieties.
