METHODS OF IRRIGATION The manner in which water is applied to the land is commonly referred to as method of irrigation. These methods are adopted to apply irrigation water to the crop depending on the landscape‚ amount of water and equipment available‚ the crop and method of cultivation of crop. The main aim of these methods is to store water in the effective root zone uniformly and in maximum quantity ensuring minimum water loss and to get optimum yield. Various methods of irrigation are: 1. Surface
