In the conditions of the Republic of Belarus there were presented five-year data of influence of application of different extra-root soluble mineral fertilizers and polyfunctional biological preparation Ehkosil on parameters of growth, yielding capacity, fruit quality, fruit biochemical components in three apple (Malus) cultivars in an apple orchard. Economic efficiency of fertilizers application was calculated, too. As a result of the realized study there was revealed the varietal reaction to the applied fertilizers: cultivars Luchezarnoe and Verbnoe showed high cultivar reaction; cultivar Zaslavskoe - low reaction. The applied fertilizers influenced the storage and preservation qualities of fruits. In accordance with the analyzed economic efficiency indexes depending on biological features of cultivars the highest economical profit at Luchezarnoe cultivar was obtained after application of Ehkosil, water-soluble complex nitrate and phosphate potassium and Akvarin-super; at Verbnoe cultivar – after application of Crystalon, Ehkosil, Ekolist-sady and Akvarin-super; at Zaslavskoe cultivar – after application of Ehkosil, complete mineral fertilizer, Akvarin-super and Crystalon. Application of multifunctional biological fertilizer Ekosil was recommended to be included into apple growing industry regulations as an element of technology.
