Goal programming formulation in nutrient management for rice production in West Bengal

Rice is the dominant crop of West Bengal. Proper nitrogen, phosphorus and potassium applications to the soil are necessary to increase its production, and improve the economic position of farmers. Application of nutrients to the soil is commonly done by using fertilizers. This paper presents a goal programming technique for nutrient management by determining the optimum fertilizer combination for rice production in West Bengal. Sensitivity analysis has been performed on the cost of fertilizer combinations and production of rice to obtain nutrient information. Game Theory has been applied to identify the nutrient proportion.
