Uttar Pradesh is a very important state in the country from agricultural point of view which occupies second position in Rapeseed-Mustard. The state is divided into four regions namely Eastern, Central, Western and Bundelkhand. The study evaluated the impact of price and selected non-price factors on area of Rapeseed-Mustard to analyse the short and long-run price elasticities and to make short term supply projections. The short run price elasticities were varied from region to region.The comparative closeness of long run elasticity to the short run elasticity in central region reveals a greater degree of adjustment in this region. The short term supply projection of rapeseed-mustard resulted that the supply would be high in Eastern region but a decrease in supply was apprehended in case of Western region.Major policy implications emerged were assuring remunerative prices to the rapeseed-mustard producers, Price incentives components of new policy strategy, Adoption of improved technology with other infrastructure facilities, installation of irrigation sources by government and strengthening infrastucture and extension services.
