A Model Demonstrating Use of Linear Programming in Determining Optimum Economic Crop Production from Soils Under Different Management Schemes¹

A model involving use of linear programming to determine optimum returns from different types of management systems which affect crop yields has been proposed. This model has been successfully applied to an example of fertilizer-yield data obtained on soils of three different fertility levels, and thereby illustrates the importance of agronomists in collecting data of this kind for the agriculturally important soil series. Value of the crop produced along with the capital available can easily be varied to meet the requirements of time and resources of the farmer. Various types of problems which may be solved by this model have been suggested.

Key Words: linear programming • fertilizer • farm planning • profit maximization
