India is the major producer of vegetable crops and ranks second in the world. But the productivity of vegetable crops is very low as compared to the leading producers. Low productivity may be caused by imbalanced nutrients supply. Proper nutrient management may enhance the productivity and quality of vegetable crops. Potassium is one of the essential plant macronutrients and is taken up by crops from soils in relatively large amounts. It is an essential nutrient for crops and plays an important role in several physiological processes in plants. In vegetables, potassium is an effective plant nutrient in two different ways; it improves the crop yield and improves crop quality. Besides that, it stimulates root growth, maintains tissue water relation, maintains electrochemical equilibria in cells and its compartments, regulates the enzyme activities, osmoregulation, improves the size and quality of fruit, translocate sugars and formation of carbohydrates. It also provides resistance against pest and diseases and drought as well as frost stresses (Hsiao and Lauchli, 1986) and (Imas and Bansal, 1999).
