Abiotic stresses such as drought, salinity, heat and cold, are greatly affecting the plant growth and agricultural productivity and causes more than 50% of worldwide yield loss of major crops every year. It is a major global problem that limits crop productivity. Yield potential of modern cultivars is limiting by stress factors. These stresses are increasing because of the declining availability of good quality water, land degradation and pollution. In the plant, stress results in nutritional imbalances causing a reduction in water uptake and an increase in toxicity, decreasing the product. In many parts of the world salinity and drought are the major abiotic stresses that limit and pose a threat to agricultural production. These stresses are interconnected as osmotic stress, resulting in the disruption of ion distribution and homeostasis in the cell. In India, abiotic stresses are the primary cause of crop failures. Hence, it is necessary for the adoption of the stress response mechanism in field crops. | Review Article https doi.org 10.20546 ijcmas.2019.804.205 Abiotic Stress Response of Field Crops Recent Approach Pratibha Kumari1 Reena Kumari2 Babloo Sharma3 Saroj Kumar Prasad4 and Rajesh Kumar Singh4 1 Department of Soil Science Agricultural Chemistry 4Department ofAgronomy Institute of Agricultural Sciences Banaras Hindu University Varanasi-221005 Uttar Pradesh India 2Department of Agricultural Engineering N.M.
