Technical Abstract: Potential water-use restrictions in some peanut (Arachis hypogaea L.) producing regions have created a need for research that examines the agronomic and economic impacts of these restrictions throughout all segments of the peanut industry. Studies will be conducted among different peanut crop rotations under non-irrigated, SDI (surface drip irrigation), and SI (sprinkler irrigation) to examine how restricted water-use influences long term peanut yield, post-harvest quality, and producer income. Field plots will be established, on approximately 16 ha located near Shellman, GA, in a randomized block design consisting of three irrigation treatments, seven crop rotations, two drip tube lateral spacings replicated three times. Three irrigation levels will be administered based on 100%, 75%, and 50% of estimated crop water-use, as well as, expert systems designed to enhance irrigation management decisions (i.e. Irrigator Pro and CAMS (Corn Aflatoxin Management System)). The experimental design will allow direct agronomic, economic, and other comparisons between non-irrigated, SDI and SI. Data collected will provide timely information on best management practices for each system.
