IMPORTANCE OF IRRIGATION

Irrigation means the supply of water to agriculture from canals, wells and tanks artificially or manually. Irrigation is essential in the regions of low rainfall. Success in dry farming depends on moisture conservation practices and judicious use of available water for irrigation. In a situation like this, it is imperative to utilise artificial means to raise crops. In India, irrigation has been practised from ancient times. The irrigation canals built by various rulers from time to time, testify the importance of irrigation in the development of agriculture.

Irrigation canals are of two types:

i) Inundation canals: Taken out directly from the rivers without constructing any barrage or dam.

ii) Perennial canals: Taken out from perennial rivers by constructing barrages or dams to regulate the flow of water.

Important canals in Punjab-Haryana are Sirhind, Bhakra. The important canals in Rajasthan are Indira Gandhi canal, Bikaner canal. In Bihar, canals of Son, Gandak and Kosi projects are important. In South the canals of Nizamsagar, Nagarjunasagar are important.
