In the conditions of the Republic of Belarus there was studied the influence of macrofertilizers and trace elements on growth and development of apple (Malus) trees of Imant cultivar in a fructifying orchard, their yield, fruit quantity and storage qualities. Application of fertilizers containing boron, calcium and a complex fertilizer Mineral-extra for apple Imant variety made it possible to obtain higher yield (37,4-39,2 t/ha) and higher percentage of sound fruit after storage keeping (82-88%) in comparison with control. Application of calcium nitrate, as well as preparations Ekolist Bor and Mineral-extra made it possible to get from 11,0 up to 72,4 Belarusian rubles extra profit for 1 ruble extra expenses. Application of macro- and micro-elements increased chlorophyll and carotenoids content in leaves. This promoted the obtaining of higher quality of fruit after harvesting and indexes of storage keeping.
