Linear programming was used for conjunctive use of canal water and groundwater to develop a cropping pattern for optimal net saving to the farmers in Bhagwanpur Distributary of the Eastern Gandak project. Constraints like total land availability, total water availability, fertilizer availability, labour availability and crop affinity were used. Average hour of operation in a year and average discharge of tube wells were estimated to calculate the total groundwater availability in a year. Six different combinations of canal water and groundwater were used. The optimum result gave the maximum net saving of Rs. 26,346/ha for the conjunctive use of 90% availability of both canal water and groundwater.
