Abstract: Rice is the most important food crop of India, extend over one-fourth of the total cropped area and providing food to about half of the Indian population. Fertilizers are an important input for producing sufficient supplies of rice to meet increasing demands. Excess application of fertilizers can have deleterious effects on environment. Therefore, optimum amount of fertilizers should be used. The optimum fertilizer management of a crop depends on crop yield. The quantity of fertilizer application is determined by the target yield and the amount of nutrients required by the crop. In the proposed method, extension agents and farmers are provided with an advice on crop and nutrient management, matching their particular farming conditions by predicting the target yield. Multi linear regression algorithm is used to forecast the crop yield.
