Surface irrigation: consists of a broad class of irrigation methods in which water is distributed over the soil surface by gravity flow. They help regulate the flow and deliver the correct amount of water to the different branches of the system and onward to the irrigated fields. Drip irrigation, essential for producing many specialty crops, is used throughout the state on farms of all sizes. it gives an elaborate knowledge on irrigation methods. Irrigation in India is carried on through wells, tanks, canals, Perennial canal, Multi-purpose river valley projects, etc. Well and Tube Well Irrigation is 60 % of the net irrigated area in the country against 29.2 per cent of canal and only 4.6 per cent of tank irrigation.
