Abstract
This study was carried out in the Western Desert Olive Field of Rawa village (Abu Koi) in 2021-2022 season to study the impact of the paper spraying with (CHI) encoded by F0, F1, F2 three levels of concentrations of 0, 100, 200 mg L-1 and (DYE) Y0, Y1, Y2 with three levels of concentration of 0, 10, 20 g L-1 and their interference in the characteristics of vegetative and fruity growth. Trees were sprayed to full wetness with three consecutive dates, the first spray was in April after full flowering, the second was in May and the last one was in June. The results showed the following: The effect of leaf spraying with (CHI) for the F2 transaction at a concentration of 200 mg L-1 in which their superior differences in the studied traits increase in the number of nodes 24.74 node plant-1, leaf area 7.20 cm2, fruit weight 6.15 g, fruit dry weight 2.05 g, iron concentration in leaves 31.63 mg kg-1. Whereas, the effect of leaf spraying with the second factor (DYE) showed the Y2 treatment with a concentration of 20 g L-1 superior differences in the studied traits in increase in the number of nodes 19.15 node plant-1, leaf area 7.05 cm2, wet weight of Leave 0.40 g, dry weight of fruit 2.10g, fruit weight 6.36 g, total yield 14.03 kg tree-1, iron concentration in leaves 24.40 mg kg-1.
