Variable Climatic condition throughout the state has led to the development of different agricultural practices. Scientists have divided the state into following agro-climatic regions:-
Western Agricultural Region:-
- It covers the sandy arid plains with low rainfall and thus about 70% of the net cropped area is under Kharif crops of bajra and pulses. This region extands to the districts of Jaisalmer, Barmer,Bikaner,Jodhpur ,Pali and Churu.
- Availability of irrigation facility has divided the region into two types of crop combination.
- Bajra-Jowar-Sesamum-Wheat region (where irrigation facilities are provided like Pali district by Jawai dam canal) and Bajra mono culture where irrigation facilities are limited. Success of Indra Gandhi Canal could be viewed from the fact that Sriganganagar and Hanumangarh are the only districts in western Rajasthan where ravi crops dominate the cropping pattern.
