Abstract: 

This study was conducted during the two seasons (2022-2023). The field experiment was carried out in a private farm in Deir Hafer area – Rasm Abboud village, to study the effect of foliar spraying with Nano iron prepared using the leaf extract of the azdrecht plant at three concentrations (50, 75, 100 mg/L), and to compare them with foliar spraying with iron sulfate at three concentrations (100, 150, 200 mg/L). The results of the study showed the positive effect of the Nano iron and iron sulfate treatments in the both seasons, as all treatments outperformed the control without spraying and the control sprayed with water only, for most of the indicators studied, and the treatment (Nano Fe 100) average weight tree productivity, average percentage of total soluble solids and reducing sugars, (73.48 Kg, 21.56 %,18.62 %), The lowest values were for the control without spraying and the control sprayed with water only.

Keywords: Nano iron, Iron sulfate, Foliar spray, Grape trees, White Shami.
