A computer algorithm was employed to assist in the analysis of alternative pumps for selecting that one which maximizes farm profit for sorghum in Arizona. Farm profit is determined by predic yield from a production function and computing variable costs for the different pumping energy requirements. Pumps are characterized by quadratic equations fitted to manufacturer's performance skpecifications with a very high degree of correlation. Alternative pumps operate at different flow rates resulting in varying water deliveries and energy usage. These last two parameters effect, respectively, the crop yield and variable cost. Proper pump selection is shown to be most important as energy costs increase. Use of the algorithm enables the rapid analysis of several conditions including alternative pumps, farm sizes, crops, and static water levels.
