Approximately 15% of peanut acreage in North Carolina are irrigated. There are several sources of information on irrigation scheduling. General comments on peanut response to irrigation can be found in 2023 Peanut Information and the 2023 Virginia Peanut Production Guide. The Peanut Money-Maker 2023 Production Guide from South Carolina also has good information. Irrigation in Georgia and Florida is more prominent than in the Virginia-Carolina Region, and good resources are available from those states. Here are links to several tools that are more precise than the rule-of-thumb information provided in NC, SC, and VA.
