The aridity of the arid and semiarid region of Rajasthan, India is considered as a great challenge for the growth of the crops due to lack of precipitation and high range of temperature. The present study focused on evaluating agricultural dynamics of the arid and semi-arid region of Rajasthan for the period of 2008-09 and 2021-22. The study comprised seven districts of Rajasthan: Barmer, Bikaner, Churu, Ganganagar, Hanumangarh, Jaisalmer and Jodhpur. Indices like crop combinations, crop diversity and agricultural efficiency of crops were taken into consideration. Hanumangarh showed 8 crop combinations to 4 from past to recent years viz. Bajra (Pennisetum glaucum), Guar seed (Cyamopsis tetragonoloba), Kharif pulses (Without Arhar) and Moth (Vigna aconitifolia), while in Jaisalmer, it was 3 crop combinations in the past while it is 6 in the recent years viz. Bajra, Guar seed , Moth , Mustard (Brassica), Mung (Vigna radiata) and Groundnut(Arachis hypogaea). A small percentage of Seasamum (Sesamum indicum) and Cotton (LINT)(Gossypium) was in the past previous years, but now, it is almost negligible. Wheat (Triticum) was observed in a lower to moderate percentage share throughout the period. There was no change in the dominant crops except in Ganganagar and Churu district. All the districts had higher crop diversification in recent years except Barmer. The result of agricultural efficiency showed that Ganganagar, Jodhpur, Hanumangarh had higher agricultural efficiency (> 100), while Barmer had the least value (< 50). Agricultural Indices efficiently visualized temporal agriculture trends in arid and semiarid regions of Rajasthan.
