In the conditions of the Republic of Belarus there were presented the experimental data for 2010 – 2011 researches of an influence of foliar application of micro and macroelement chelated fertilizers CompleMet on growth, fructification, fruits commercial quality and storability, leaf biochemical composition of six cultivars and fruit biochemical composition of eight cultivars of an apple (Malus) tree in an intensive fruit bearing orchard. As a result of the researches made it was established, that gradual application of the chelated fertilizers CompleMet had made a positive influence on apple trees growth and fructification, fruits commercial quality and storability. Basically, growth processes were passing more intensively at gradual foliar application of the chelated fertilizers CompleMet. At all studied apple cultivars their yield, specific efficiency of a stem, average fruit weight and output of the first and second commercial cultivars were higher at the variant of the experienced agro method. A foliar application of the chelated fertilizers CompleMet made a positive influence on biochemical composition of apple leaves and fruits. It was shown, that concerning the control under the influence of the experienced agro method there was observed an increase in leaves content of calcium, iron, zinc and magnesium for the majority of the cultivars. The content of dry matters and calcium increased in apple fruits of all cultivars. The content of iron, magnesium and zinc increased at the majority of the cultivars.
