Rajasthan has Net Cropped area of 183.49 Lac hectares, out of this, approximately 75% of area is rain-fed (116.88 lac hectares) and only 25% is irrigated area (66.61 lac hectares) (1). However, this 25% irrigated area contributes more than 50 percent of agricultural output. Main sources of irrigation in Rajasthan are:
Net Irrigated Area in Rajasthan by Source
- Open Wells: 31.62%
- Tube-wells: 41.91%
- Canals : 24.45%
- Tanks: 0.84%
- Other sources: 1%
As can be seen above, 73% of irrigation is through tube-wells and wells placing enormous stress on groundwater. It is particularly alarming that share of tube-wells over the last four decades has shot up from 1 percent in 1967-68 to 39 percent.
Irrigation in Rajasthan by Crops:
- Of the total irrigated area, 35.79 percent is under wheat, 23.65 percent under rape seed and mustard, and 5.8 percent under grams.

- Major & Medium Irrigation Project Potential: 2.75 mh
- Minor Irrigation Project Potential: 2.37mh
- Surface Water: 0.6 mh
