INFLUENCE OF OF MICROFERTILIZERS ON THE YIELD AND QUALITY OF VEGETATIVE MASS AND RHIZOMES WITH ROOTS OF ECHINACEA PURPUREA (L.) MOENCH. PLANTS IN THE CONDITIONS OF THE RIGHT-BANK FOREST-STEPPE OF UKRAINE

Abstract

The article, based on the results of scientific research in 2021–2023, highlighted the essence of adding trace elements and their use in the soil, which have the same valence and the ability to partially change, therefore, an important achievement was the determination of the function of trace elements and their safe use on Echinacea plants of purple varieties “Charivnytsia” and “Polish Beauty”. The soils of the Right Bank Forest-Steppe of Ukraine are poor in trace elements, their amount depends on the degree of podzolenization, the mechanical composition of the soil and the content of humus, which is quite low – 1.97%. It has been confirmed that Echinacea purple is demanding of trace elements such as boron, zinc, copper, manganese, molybdenum, cobalt, to withstand adverse weather conditions, lodging and drought. It was established that the effectiveness of the use of microelements played an important role in the formation of the plant yield of the studied culture. Molybdenum with the yield of vegetative mass on average, 687 g from the vessel, is higher than the control variant by 162 g, rhizomes with roots – 598 – 135 g were obtained according to the results of research in the Charivnytsia variety. Similar indicators for the yield of rhizomes with roots of 578 g, which is 244 g higher than the control, were observed in the Poliska krasunya variety. According to chemical parameters, the highest content of essential oil of vegetative mass 0.28% and chicory acid 1.3% was provided by Charivnytsia variety. The difference between varieties was small. Research allows us to conclude that in the conditions of the Right Bank Forest Steppe of Ukraine, it is possible to grow Echinacea purple on soils poor in these microelements, which regulated the quality of raw materials by applying them.
