The present investigation was carried out during two successive seasons 2023 and 2024 on ten years Balady lime trees, grown in Malawi district El-Minia Governorate, where the soil texture was sandy, since water table depth is not less than two meters. The orchard was irrigated throw drip irrigation system. The chosen trees were planted at 4 X 5 meters apart. This investigation further highlights the importance of spraying iron, zinc, and boron on the yield and fruit quality of Balady lime trees grown under sandy soil and salinity stress conditions. The results clearly showed that spraying Balady lime trees with the three micronutrients (Fe, Zn and B) at 100 & 200 ppm, either singly or in combination, significantly enhanced the yield and fruit physicochemical properties of Balady lime trees compared to untreated trees. However, spraying Boron individually was more effective than spraying Fe or Zn on the the different examined properties. Furthermore, the combined treatment with 200 ppm Fe, 200 ppm Zn and 200 ppm B recorded the best results on the yield and fruit physical and chemical properties, during the two experimental seasons respectively.
