Which of the following sources of irrigation accounts for the largest proportion of the irrigated area of India?

Answer: [C] Tubewells

Tube wells are, today, the most popular source of irrigation in India because of their capacity to irrigate larger area. Well Irrigation is common in alluvial plains of the country except the deserts of Rajasthan. Plains of UP, Bihar, Gujarat, Karnataka & Tamil Nadu are the states which are more prominently under the well irrigation. Canals are second most important source of irrigation in India after wells and tube wells. The Canals are irrigating those lands which have large plains, fertile soils and perennial rivers.
