The objective of the research program of which this project is a part is to determine crop water requirements for the cerrado region of Brazil. Knowledge of the influence of evapotranspiration, soil hydraulic properties and water management on crop growth is important for both the agronomic and economic evaluation of irrigation development and the extension of rainfed agriculture. In the case of irrigation a knowledge of crop water requirements in relation to yield will allow for better irrigation planning and design, as well as more realistic comparison of the relative benefit of using water for irrigation rather than for other purposes. In the case of rainfed agriculture, such knowledge will allow for more realistic evaluation of the feasibility fo extending agriculture into areas where dry spells during the wet season are likely to reduce yield potential, as well as establish a basis for improving crop tolerance to short droughts. The relationship between evapotranspiration, soil water properties and crop growth is complex. For this reason, dynamic plant-environmental simulation models were developed and used to predict water budgets and crop growth under a range of irrigation water treatment. Specifically, a microcomputer-based program (GAPS) was designed to allow construction of several simulation models from various mathematical representations of processes in the soil-plant-atmosphere system. These representations, for the most part, had been previously published but not extensively tested,....
