A computer Program for Machinery Cost Estimation in multi-farm system (AP-MACE) is a user-friendly interactive program written in a Visual Basic (VB) programming environment for machinery management. It allows the user to interact with it by entering the required inputs and it will carry out the interactive calculations. The AP-MACE can predict the effective field capacity for different implements (ha/hr), find out machinery cost per hour and per unit area (feddan, hectare), calculates the total operation cost per ha, and per hour, estimates total costs of owning and operating machinery for various crop rotations and finally evaluates the cost of using different machines with different tractor sizes. The program enables the user to print out the output which is displayed on the screen. AP-MACE was successfully verified statistically in comparison to Habeela agricultural (South Kordufan State) scheme existing machinery program and Iowa State University model. The comparisons indicated that there were no significant differences. Validity and sensitivity tests of the model indicated that the AP-MACE could be applied to any real-life case successfully and with confidence for any crop farm.
