Good nutrition for fruit Transplant, including olives, depends on the amount of mineral elements present in the soil or added in the form of foliar fertilizers to these Transplant, this experiment aimed to know the response of Transplant of two olive cultivars (Sorani and Nabali) to foliar spraying with two concentrations of folic acid (0 and 100 g L^-1) and three concentrations of organic silicon (0, 5 and 10 mg L^-1) and their effect on the growth and mineral content of the Transplant. The results showed that foliar spraying with folic acid at a concentration of 100 g L^-1 and silicon at a concentration of 10 mg L^-1 gave the highest significant values in the leaf content of mineral elements (nitrogen, phosphorus, potassium, zinc and iron in addition to carbohydrates) and significantly exceeded the comparison treatment, while there was no effect of the two study cultivars on all of these traits. It also became clear that all interactions between the factors, especially between the high concentrations, gave the highest values of these traits, especially when the triple interaction between the treatment (100 g L^-1 folic acid + 10 mg L^-1 silicon for the Sorani variety).
