The choice of irrigation method should be based on the surface topography, soil characteristics, crop to be grown, irrigation source, depth of water application, labour requirement, level of technology and layout and management. The criteria to be adopted for selecting irrigation method are given in Table 13.4. The irrigation method generally adopted by the farmers […]
