During the past half century, the Punjab state achieved exemplary growth in food grain production. Consolidation of landholdings, reclamation of new agricultural lands, development of irrigation, use of biochemical inputs comprising high yielding variety seeds, chemical fertilizers, insecticides and mechanical inputs were among the important factors which helped agriculture in the state in making rapid strides The fast shift in the area from traditional diversified crops to mono-culture of rice wheat system was driven by forces such as price policy, technological change, market infrastructure and low cost of irrigation. The underground water is being used indiscriminately and due to over exploitation of water resource, the sustainability of existing crop systems is becoming doubtful creating critical second generation problem. Evidently, the state agriculture has reached at a stage of stagnation whereas the social cost is increasing due to environmental degradation. Though the economic evaluation of social cost is a cumbersome process, an attempt has been made to access the performance of different crops and cropping pattern in the state of Punjab using alternative scenarios like market prices, economic prices (without subsidies) and natural resource valuation (NRV) considering environmental benefits like biological nitrogen fixation and greenhouse gas costs. The results revealed that on the basis of market prices, basmati and paddy common generated net returns of
