In the experiment effects of Promalin and three foliar fertilizers on the growth and branching of maiden apple trees of the cultivars: Jonagold and Idared were compared. Additionally, the content of macroelements in the leaves of maiden apple trees of the cultivars mentioned above was assessed. The preparation Promalin significantly increased the number of long shoots of maiden trees of Jonagold and the dwarf shoots of Idared comparing with the control. At the same time it did not initiate the formation of flower buds. The foliar fertilizers used did not significantly differentiate the results of the growth and branching of maiden trees. However, they significantly increased the number of flower buds formed. The chemical agents applied via the foliage did not unambiguously influence the content of macroelements in the leaves of maiden apple trees cultivated in a nursery
