The purpose of this study was to see how biochar treatments with and without magnetic water irrigation affected fruiting, fruit characteristics, and mineral content of the Hayany date palm cultivar grown at the South Sinai Research Station (Ras Sudr), Desert Research Center, South Sinai Governorate, Egypt during the 2018 and 2019 seasons. According to the findings, biochar treatments and magnetic water irrigation had a substantial effect in both seasons. In combination with magnetic water irrigation, biochar treatment at 3 kg/tree resulted in increased production and bunch weight. In both seasons, the identical treatment resulted in the highest fruit weight, flesh weight, volume, and dimensions. Furthermore, research revealed that biochar treatment at 3 kg/tree and magnetic water irrigation significantly boosted total soluble solids, decreasing sugars, and total sugars content. In comparison to the control and other treatments, treatment biochar at 3 kg/tree gave higher values of N, P, K, Ca, and Mg contents in pinnae of Hayany date palm cultivar in the first and second seasons.
