irrigation is the method in which water is supplied to the plants at regular intervals of agriculture.
It is used to assist in the growing ofagricultural crops, maintenance of landscapes, and revegetation of disturbed soils in dry areas and during periods of inadequate rainfall. Additionally, irrigation also has a few other uses in crop production, which include protecting plants against frost,[1] suppressing weed growth in grain fields[2] and preventing soil consolidation.[3] In contrast, agriculture that relies only on direct rainfall is referred to as rain-fed or dry land farming.
Irrigation systems are also used for dust suppression, disposal of sewage, and in mining. Irrigation is often studied together withdrainage, which is the natural or artificial removal of surface and sub-surface water from a given area.
