The feedback investigation results of 6 sample apple (Malus) cultivars of different maturing terms on macro and micro chelated nutrient fertilizer agency 'CompleMet' were presented in the conditions of the Republic of Belarus. They were based on the revealed changes in their maintenance of solid and pectic substances, free organic and ascorbic acids, soluble sugars, pectic substances and macro elements (nitrogen, phosphorus, potassium). It was shown positive handling effects on nutritious and vitamin fruit value which is appeared to be in much greater degree at late winter cultivars, rather than at autumn and early winter ones. The cultivars 'Alesya' and 'Verbnaye' were characterized by the most considerable advantages in biochemical fruit composition in variants with handling, in comparison with the control, meanwhile the cultivar 'Belorusskoye sladkoye' was characterized by the least ones. All apple cultivars came short greatly to the cultivar 'Alesya' by 2,2 – 11,4 times for fruit quality improvement degree. The cultivar 'Verbnaye' showed the least distinctions meanwhile the cultivar 'Belorusskoye sladkoye' – the biggest ones.
