The study examines the impact of the Pradhan Mantri Krishi Sinchai Yojana (PMKSY) on irrigation development and agricultural performance in Jhalawar district of Rajasthan. Secondary data covering the period from 2014–15 to 2023–24 were analyzed to assess changes in irrigated area and crop yields. The findings show that the district achieved more than 31,000 hectares under micro irrigation, ranking eleventh in the state and surpassing 22 districts in coverage. Crop-wise analysis reveals major gains in mustard, gram, garlic, and wheat, which registered significant improvements in both irrigated area and yield. Paddy and rice expanded in area but recorded only moderate yield gains, while coriander and fenugreek experienced a decline in irrigated coverage. Garlic and onion displayed sharp fluctuations yet confirmed a shift toward high-value horticultural crops. The results indicate that PMKSY has strengthened water-use efficiency and promoted crop diversification in Jhalawar. The study also identifies challenges such as high installation costs, limited training, variable crop responses, and the need for region-specific strategies. The scheme has acted as a catalyst for irrigation-led growth in Jhalawar but requires complementary measures for sustaining balanced and inclusive agricultural development
