Effect of Magnetic Water Irrigating on Fruit Quality and Storability of Valencia Orange

Egypt is considered the first universal in orange production or export, as Egyptian oranges are distinguished by taste and quality that are different from other oranges worldwide. The cultivated area increased year after year. However, the problem in the places that have been added to the cultivated area with oranges is sometimes the salinity of the soil and sometimes the salinity of the irrigation water. Irrigation by magnetic water is a method to reduce the impact of irrigation water that contains salinity. Many experiments have been conducted on irrigation by magnetic water, and the experiments have shown an affirmative impact on the quality and productivity of the crop. This investigation was carried out in the 2021 & 2022 seasons to investigate the impact of magnetic water irrigation on the goodness of fruits of cv. Valencia orange at harvest, through cold storage (7C^o) and storage at room temperature at 24 C^o. At harvest time trees treated by magnetic water irrigation, fruits had increased percentages of fruit weight, volume, firmness, peel thickness, and attribution of juice weight than was taken in normal water. During cold storage at 7C^o and at room temperature at 24C^o, fruits treated with magnetic water had less weight loss, decay, and increase in TSS/acid ratio in all storage conditions than fruits treated with normal water.
