The dataset consists of weather, yield and soil moisture data seasons 2021-23 for a Nadorcott mandarin orchard under various drip irrigation treatments in Nelspruit, South Africa. Capacitance probe, ileaf weather data, yield and quality data are all summarized within this dataset. Drip irrigation has emerged as a very effective method for the irrigation of citrus and recent advances in drip irrigation technology have reduced emitter delivery rates by 70% compared to conventional drip, in an attempt to increase irrigation efficiency by decreasing drainage and increasing water storage in the rootzone.
