The research was conducted in one of the private orchards in Al-Musayyib District / Babylon province for the seasons 2020 and 2021 to study the effect of spraying with potassium silicate, boron and vitamin C on some vine traits of the French black grape cultivar and bred on wire mesh arbour. the experiment was conducted according to The randomized complete block design (RCBD)as a factorial experiment, the L.S.D. test was used at a probability level of 0.05 to compare the averages. The spraying treatments were as follows: 1- Spraying with potassium silicate K2SiO3 (35% potassium silicate, which contains 12% potassium oxide K2O, in two concentrations (250 and 500 mg. L-1). 2- Spraying with boron in the form of boric acid H3BO3 (B 17%) before flowering opens with two concentrations (50 and 100 mg. L-1). 3- Spraying with vitamin (C) in the form of ascorbic acid at a concentration of (50 mg. L-1). 4- Spraying with distilled water only as a control treatment. The results showed that the spray treatment with potassium silicate concentration of 500 mg. L-1 with boron at a concentration of 50 mg. L-1 with vitamin C at a concentration of 50 mg. L-1 led to a significant increase in the leaves content of nitrogen, phosphorous, potassium, boron, calcium and zinc for the two seasons, respectively, while the lowest readings were in the treatments that were not sprayed with potassium silicate. The percentage of total carbohydrates in leaves and canes was also affected by spraying treatments, as the spraying treatment resulted in potassium silicate at a concentration of 500 mg. L-1+ boron and vitamin C at a concentration of 50 mg. L-1of each of them significantly increased the percentage of carbohydrates in leaves and for both seasons compared to the rest of the treatments.
