A general purpose, low cost, and PC-based Linear Programming model was formulated for the evaluation of energy crops in an existing farming system. The model consisted of an objective function i.e., maximization of return; activities, and constraints. I pil-ipil was introduced into a base case model (Wheat, Maize, and Tractor activities) with and without the additional capital. The model analysis resulted in an increase of 15% in return with the introduction of ipil-ipil. The return was three times greater when capital was also provided in the model. This model's performance was satisfactory in evaluation of farm enterprises singly or in conjunction with other new activities.
