Abstract 

 The experiment was conducted during two seasons (2022-2023) on Nectarine trees (Legrand cv.) planted at the Kassab Research Station of Scientific Agricultural Research Center – Latakia governorate; to study the impact of different concentrations of urea and humic acid foliar application and their interaction on the improving the characteristics of Nectarine fruits variety. The experiment showed that the treatments of application urea and humic acid together were significantly superior to the treatments of individual application and control in most of the studied traits. The foliar application treatment (urea 3 g/l + humic 2 g/l) recorded the highest values in terms of fruit weight, fruit size and total soluble solids (130 g, 132 cm3, 11.47 %) respectively, whereas foliar application treatment (urea 3 g/l + humic 1 g/l) recorded the highest value in fruit content of total sugars    (7.93 μg /ml of glucose).

Keywords: Nectarine, Foliar application, Urea, Humic acid
