Abstract: 

The research was carried out in in Kassab research station of scientific agricultural research center – Latakia during two years (2022-2023) on peach trees (Michelin cv.) governorate to study the impact of potassium silicate (3 and 5 g/l) and potassium humate (2 and 4 g/l) foliar application on some characteristics of fruit growth of the studied trees. The experiment showed that the foliar application with potassium humate (4 g/l) was significantly superior to other treatments in terms of fruit weight, fruit size and total soluble solids on peach fruit (134.12 g, 125 cm³, 10.63 %) respectively. Also, the foliar application with potassium humate (2 g/l) improved the percentage of anthocyanin pigment in fruits (23.53 mg/100g fresh weight) compared to control trees (17.81 mg/100g fresh weight).

Key words: Peach, Foliar application, Potassium silicate, Potassium humate.
