Proper nutritional condition is essential for the fruiting phase of The present investigation was carried out during two successive seasons 2023 and 2024 on twenty one ten years old Balady lime trees, grown in orchard located at Drawe Village Malawi district Minia Governorate, where the soil texture was sandy, since water table depth is not less than two meters. The trees were irrigated throw drip irrigation system. The chosen trees were planted at 4 X 5 meters apart. Two concentrations of seaweed (0.05% & 0.1%) and Fe (100 & 200 ppm) as well as their combinations were examined. The obtained results showed that spraying seaweed and Fe individually or in combination was capable to improve the vegetative growth, nutritional status, yield, and fruit quality. However, the combined application of seaweed and Fe was more effective than spraying each one individually. These findings were true during the two experimental seasons.
