Abstract: 

The experiment was conducted during two years (2022-2023) on Nectarine trees (May crest cv.) in beet shofan-tartous-to study the impact of different concentrations of urea and humic foliar spray and their interaction on the improvement of vegetative growth. It was found that the combined application of urea fertilizer and humus gave the highest significant effect compared to the individual application in most of the indicators studied, as the treatment (urea fertilizer at a concentration of 2 g/l + Humic 2 g/l) was superior to the rest of the treatments in terms of the average diameter of modern plants ( 0.65 mm, the percentage of dry matter in the leaves (55.22%), the percentage of phosphorus (0.32)%, and the percentage of potassium (1.85)% alcohol in the leaves, and the treatment (urea fertilizer at a concentration of 3 g/L + Humic 2 g/L) was significantly superior in terms and of the percentage of alcohol chlorophyll and in Leaves: The yield reached (1.39)% from the (urea fertilizer) treatment at a concentration of 3 g/l + Humic 2 g/l in terms of productivity (35.72) kg/tree and yield (2232.5) kg/dunum.

Keywords: Nectarine, Foliar spray, Urea, Humic.
