Abstract
Two advanced peanut irrigation scheduling tools were developed and evaluated. The first involvedmaking, Irrigator Pro, a public-domain tool developed by the USDA-ARS National Peanut
Research Laboratory, compatible with soil moisture sensors that measure volumetric water
content. The new version offers automated data entry and provides hourly or daily irrigation
decisions. The second tool involved developing an evapotranspiration (ET) -based model that was
incorporated into the existing SmartIrrigation CropFit App. The model includes a localized
growing degree day (GDD) -based crop coefficient (Kc) curve. Both tools were compared to other
advanced irrigation scheduling tools in replicated plot studies at two locations in southern Georgia,
USA. The results showed that both tools performed at least as well as the rest of the treatments
and in some cases, they outperformed them in irrigation water use efficiency. The applications
were released for public use in April 2023 and will continue to be evaluated in the upcoming
seasons with on-farm trials.
