The present study has analyzed the “Optimum Cropping Patterin Semi-Arid Eastern Plain Agro-climatic Zone of Rajasthan state by using alternative three price scenarios namely market prices, economic prices (net out effect of subsidy) and natural resource valuation (NRV) considering environmental benefits like biological nitrogen fixation and greenhouse gas costs. In this study, unit-level cost of cultivation data for the triennium ending 2013-14 which were collected from Cost of Cultivation Scheme, MPUAT, Udaipur (Raj.) has been used. It has analyzed crop-wise use of fertilizers, groundwater, surface water, subsidies and optimum crop plan by using linear programming with the help of GAMS. Results from the present study indicated that even after netting out the input subsidies and effect on environment and natural resources, clusterbean-vegetable crop sequence produced the higher net return of ` 215187 per hectare followed by clusterbean-chillies (` 108590/ha) crop sequence under the set of marketing infrastructure, minimum support prices, agricultural technological know-how, climatic conditions and available irrigation facilities existed in this semi-arid eastern plain. Optimum crop plan model of this zone indicated that area shifted from sorghum, maize, cowpea and mothbean towards blackgram, greengram and clusterbean in kharif season whereas in rabi season, area shifted from cumin and onion towards the chillies, vegetables, gram and fenugreek and towards the rapeseed and mustard and wheat to some extent. Therefore, existing gross cropped area has increased at all the three price scenario by 13.49 per cent from 2719.13 thousand hectares to 3086.00 thousand hectares in optimal crop plan.
