Efficiency of microfertilizer application to medicinal plants grown under conditions of southern forest-steppe of Western Siberia

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 millefoliumL.,Tanacetum vulgareL.,Echinacea purpureaL.) on meadow-chernozem soil in the southern forest-steppe of Western Siberia. It was found that the most effective forAchillea millefoliumwas the application of copper fertilizers in the soil at a dose of Cu9.7, providing an increase in yield by 43.2 % relative to background; forTanacetum vulgare –zinc fertilizers at a dose of Zn60(+42.9 % relative to background) and forEchinacea purpureacopper fertilizers at a dose of Cu9.4(+60.3 % relative to background).
