The experiment was conducted for two years (2020-2021) on Nectarin trees (Legrand cv.) in Kassab research station of the scientific agricultural research center – Latakia governorate to study the impact of different concentrations of urea and humic foliar spray and their interaction on the improvement of vegetative growth. The experiment showed that the spray with urea and humic gave the highest significant effect compared to individual spray in most of the studied indicators. Comparing the foliar spray treatment (urea 2 g/l + humic 2 g/l) with other treatments, it recorded the highest significant values in terms of average shoots diameter, dry matter percent, and phosphorus and potassium contents on leaves, whereas foliar spray treatment (urea 3 g/l + humic 2 g/l) recorded the highest significant value in terms of total chlorophyll content of leaves.

Keywords: Nectarine, Foliar spray, Urea, Humic.
