The process of supplying water to crop plants in fields through canals, wells, reservoirs, tube wells etc. is known as irrigation. Wells, tube wells, ponds, lakes, dams, rivers and canals are some of the sources of irrigation.

Modern methods of irrigation which conserve water:

Drip irrigation

Water is supplied through perforated pipes. Pipes are placed in rows between the plants close to the roots. It is the best method for water scarce regions because a lot of water is saved. It is used for fruit orchards, gardens and trees.

Sprinkle irrigation

Sprinklers or spray guns are attached to a large hosepipe at regular intervals to spray water. It is suitable for all types of crops.
