Crop Water Use as a Function of Climate Variability in Georgia

Proceedings of the 1999 Georgia Water Resources Conference, March 30 and 31, Athens, Georgia.Climate variability in Georgia during the 20th century was investigated in this project. Crop water use of important agricultural crops, including maize, soybean and peanut, was assessed with crop simulation models of the decision support system for agrotechnology transfer (DSSA T). Spatial distributions of irrigation requirements during the growing season are presented. It was found the requirements for supplemental irrigation have a high negative correlation with precipitation received during the growing season.Sponsored and Organized by: U.S. Geological Survey, Georgia Department of Natural Resources, The University of Georgia, Georgia State University, Georgia Institute of TechnologyThis book was published by the Institute of Ecology, The University of Georgia, Athens, Georgia 30602-2202 with partial funding provided by the U.S. Department of Interior, geological Survey, through the Georgia Water Research Insttitute as authorized by the Water Research Institutes Authorization Act of 1990 (P.L. 101-397).
