The influence of microfertilizers on the accumulation of potato tuber weight in the conditions of the Right Bank Forest-steppe of Ukraine has been investigated using the medium-late varieties ‘Alladin’ and ‘Dar’. Plant foliar treatment were performed at the budding-flowering stage with the preparations: Reakom (boron che-late – 10g/l + (HEDP+acetic acid-chelated micronutrients), Kristalon special (N18P18K18 + EDTA, DTPA chelated micronutrients) and Rosasol (N18P18K18 + EDTA chelated micronutrients). It was established that microfertilizer application had a significant effect, beginning from budding to the stage when the tops begin to die, on the accumu-lation of potato tuber weight in all experimental variants. On average in the research years (2015-2017), the highest results: 683 g/bush (Dar) и 624 g/bush (Alladin) were obtained from the use of the preparations Reakom (4,50 rg/ha) and Kristalon special (2,50 kg/ha). Foliar fertilization influenced growth processes. They occurred more intensively compared with the control (without plant treatment) and were maintained until the beginning of plant top drying. All this contributed to the growth of the tuber weight and to increased crop yield and product quality
