Plant and Soil Science

The article shows the state of the problem with the introduction of ginseng in thePolesie zone of Ukraine. The main goal was to study the effect of Reakom micronutrient fertilizers (Zn, Cu, B, Mo, Co) at a dose of 2.5 l/ha and 5 l/ha on the growth of the aerial part and the roots of three-year-old seedlings and six-year-old ginseng seedlings, the contents of macro- and micro elements in plant leaves, the fruiting productivity of six-year-old plants in the conditions of Polissya Ukraine. The studies were conducted on the territory of the Boyarsky LDS on sod-podzolic light-loamy soil on fluvioglacial sands, which are underlain by moraine. The use of Reakom micronutrient fertilizers in foliar dressing of plants contributed to an increase in fruiting productivity and an increase in root mass by 25-35%, the phytochemical parameters of which corresponded to the requirements of the temporary pharmacopoeial article42В-163/160 / 37-536-97 and were classified as commodity. The greatest yield of three-year-old ginseng roots was recorded at the maximum dose of Reakom foliar fertilizer for garden crops, but they had the greatest mass when sprayed with Reakom for ginseng N 1 at a dose of 5 l/ha. Six-year-old ginseng roots formed the maximum productivity and root yield with a lower dose of Reakom for ginseng N 2 (2,5 l|ha).
