Drought and salt stress are the major problems all over the world. High salt contents in soils make the soil sodic and affect crop cultivation in large areas of both developed and developing countries. A sodic soil contains high concentration of sodium content associated with the negatively charged clay particles. Abundance of Na+ and Cl- ions decreases the activity of other essential elements in the soil and can lead to reduction in uptake of growth support by the plants. The direct effects of salt stress on plant growth involves plant nutrient deficiency, growth and yield. To overcome the...
