The problematic of this study is the lack of consistency with supply theory of the trend of price and the supply of some selected crops in Jigawa state as observed by the researcher. This study using the Nerlovian model has estimated the responses of millet, sorghum, sesame and groundnut crops areas to changes in their prices and other relevant variables in Jigawa state, Nigeria. The time period covered in the analysis is from 1994 - 2007. The coefficients of the area response models were estimated for the individual crops and at the aggregate level using ordinary least squares multiple regression method. Quantitative estimates show that the short run and long run changes in own-price, lagged hectarages and lagged production were not significant in explaining the response of millet, sorghum, sesame, and groundnut farmers during the period under review
