Formation of a crop of medicinal crops (Tanacetum vulgare L., Echinacea purpurea L.) under influence of essential microelements

Relevance. A wide range of pharmacological effects of tansy and Echinacea purpurea determine the continuing interest in the study of these cultures. Medicinal crops contain not only a large number of biologically active substances, but also trace elements necessary for normal growth and development. Agronomic bio-enrichment of medicinal raw materials allows you to increase productivity, manage product quality in the direction of enhancing the pharmacological action. Thus, the aim of the work was to study the effect of various doses of zinc acetate on the productivity of two medicinal crops of tansy and Echinacea purpurea. Material and methods. Studies were conducted from 2012 to 2018 on meadow-chernozem soil of the southern forest-steppe of Western Siberia. As objects of research, perennial medicinal crops were chosen - Tanacetum vulgare L. and Echinacea purpurea L. Zinc fertilizers were applied in the background (N125, N135P45K45) used in acetate form...
