Abstract

The article presents the results of studies on the effectiveness of mineral fertilizers (zinc and copper) in the cultivation of perennial medicinal crops (Achillea millefolium L., Tanacetum vulgare L., Echinacea purpurea L.) on meadow-chernozem soil in the southern forest-steppe of Western Siberia. It was found that the most effective for Achillea millefolium was the application of copper fertilizers in the soil at a dose of Cu_9.7, providing an increase in yield by 43.2 % relative to background; for Tanacetum vulgare – zinc fertilizers at a dose of Zn₆₀ (+42.9 % relative to background) and for Echinacea purpurea copper fertilizers at a dose of Cu_9.4 (+60.3 % relative to background).
