In the conditions of the Republic of Belarus in 2007-2008 there was analyzed the influence of leaf-feeding fertilization with urea and a complex of trace fertilizers produced by the BASF Company (ADOB Bor and Basfoliar 12-4-6) on growth and fructification of apple (Malus) trees of different varieties. There was noted a different reaction of apple cultivars to the applied fertilizers. In Antey cultivar the leaf-feeding fertilization with urea promoted favored the yielding of fruits with larger mass and higher yield production of the first class fruit. In cultivar Slava Pobeditelyam the leaf-feeding fertilization with urea favoured enhanced area of lamina, chlorophyll and caretoneds content, yield, quantity of first class fruit and profit. In ciltivar Pamyat Subarovoy – urea application enhanced yield, average fruit mass, quantity of first class fruit and profit. For Alesya cultivar – it enhanced the average area of lamina and average fruit mass. Leaf-feeding application of trace fertilizers increased the average area of leaf lamina on accretion at cultivars Antey and Alesya. In varieties Slava Pobeditelyam and Pamyat Subarovoy in the variants with application of trace fertilizers there were stated higher yields, quantity of first class fruit and profit per a hectare.
