Irrigation Potential

Expansion of irrigation facilities, along with consolidation of the existing systems, has been the main part of the core strategy for increasing production of food with sustain and systematic development of irrigation grains. The irrigation potential through major, medium and minor irrigation projects has increased from 22.6 million hectares (mha) in 1951 when the process of planning began in India to about 102.77mha at the end of tenth plan. Plan-wise irrigation potential created and utilized through major, medium and minor irrigation projects in the country is as indicated hereunder:
