Background: The basic challenge every farmer in India faces is to increase profitability level and minimize the cost. For this, it is essential to know how the cost of cultivation and profitability is changing of crops over a period of time. The present study attempted to estimate the cost of cultivation, cost of production and returns of major pulse crops in the Rajasthan state. For workout the economics of pulses crop, secondary data was collected from 2000-01 to 2021-22 which is compiled from various sources and publications for profitability analysis of pulse crop. Methods: The study was conducted in Rajasthan state and analysis done for 22 years used the “Cost of Cultivation of Principal Crops in Rajasthan” by DES, New Delhi uses different cost concepts for estimating costs and returns. In the present study, the cost C2 was considered for computing profitability. Cost C2 in CCPC data covers all the variables and fixed costs. Result: The actual cost of production of gram crop increased from Rs. 1772.32 per quintal in TE 2003 to Rs. 3650.5 per quintal in TE 2021. Return per rupee invested increased from 2.52 to 3.01 during TE 2003 to TE 2021. Cost of production of urad crop had increased from Rs. 2520.63 per quintal in TE 2003 to Rs. 7385.45 per quintal in TE 2021. The return per rupee invested in cost A2 had reduced from 2.14 in TE 2003 to 1.99 in TE 2021. Moong crop also showed increasing trend for cost of production from Rs. 2696.08 per quintal in TE 2003 to Rs. 7385.45 per quintal in TE 2021. Return for each rupee invested a increased from 2.10 in TE 2003 to 2.14 in TE 2021. Return per rupee invested was not profitable for the farmers for urad. Therefore, proper processing and procurement policy for these crops grown by the farmers should be implemented. Urad crop need more efficiently technological breakthrough to reduce cost of production and proper price incentive to pace with other pulses crops in the state.
