The CERES crop growth simulation models for sorghum, maize and mUlet. and other models like SOYGKO and PNUTGRO are ,becoming widely used for various applications in agricullure. Thew models use data fllw whose structure was developed by IBSNAT. As the use of theae models becomes more widespread the amount of data coded in the IBSNAT format will become more readily available. There 14 therefore, an advantage in having an operational, dedicated, soil water balance model compatible with the XBSNAT data format ao that water balance analws can be done without reformatting the data. WATERMAN is a model developed to achieve this objective. The program obtains the required weather, soil and crop information from the EXP.DIR and WM.DIR files. All required mil profile variables of the chosen soil type are then input from the SPROFILE* file. The user can select several applications, such as dally or periodic soil water balance, daily water contents of various layers and irrigation scheduling with or without consideration of rainfall probabilities Test runs at Samaru. Nigeria, gave acceptable results.
