Technical Abstract: Texas, with its extremes in temperature, relative humidity, and soils, contains an excellent set of sites for testing maize and sorghum yield simulation. In this study we tested ALMANAC's ability to simulate maize and sorghum yields at four irrigated and five dryland sites in Texas. These vary from warm humid locations in the Rio Grande valley and near the Gulf of Mexico to low humidity, high evaporative demand sites in northern TX and the High Plains. Using yield data from hybrid performance trials for these sites, the model reasonably simulated yields of both corn and sorghum at these diverse sites for 1991 to 1995. These data sets and the model and parameters are available to users to aid in development of additional data sets at other locations.
