Abstract: We suggest a Linear Programming Model (LP) for optimal allocation of irrigation water for rice production at the Kpong Irrigation Scheme based on a set of fixed constraints and the maximization of the net returns. In this paper, the System of Rice Intensification (SRI) is incorporated into a formulated LP Model. The main crop was rice but was factored into the LP Model as six (6) distinct crop categories on the basis of percentage of irrigation water utilized and the seasons in which they are grown. Comparison of results obtained by using existing farming plan and the LP Model show that results obtained from the LP Model were improvements on the existing farming plan. The LP Model saved 50% of irrigation water in both the major and minor seasons and also chalked an increment of 101.50% of the net returns.
