Abstract: Computer simulation models have been developed which predict growth, development, and yield for grain legumes. These models can be applied for yield prediction as well as water management decisions. The soybean and peanut models, SOYGRO and PNUTGRO, were used to generate longterm yield, evapotranspiration, and irrigation demand for Gainesville, FL, and Tifton, GA, for six different soils. High yield levels were a function of location and total irrigation, while low yields were a function of location and soil water holding characteristics.
