Farm planning problems are much more complex. Farmers do not only produce different crops, but also have to choose among a variety of ways of producing them. Crop planning may involve choices about varieties, planting dates, fertilizer and pesticide treatments. Linear programming has proved a very flexible tool for modeling these kinds of complexities. In this paper, a linear programming model was developed to determine the optimal crop combination for a rural farmer. Crops considered were maize, soya beans and cotton. The model produced an optimal crop combination that gives higher income than that obtained from the farmer’s plan. The income difference was 72.79 percent.
