Relevance. For the production of pharmaceutical products from raw materials of Echinacea purpurea L., it is necessary to have a sufficient amount of high-quality seeds when planting production areas with high yields of aboveground mass.Methods. On Echinacea purpurea of the second year of vegetation in order to increase herbage yield and seed productivity, tests of organomineral fertilizer EcoFus (1.5 l/ha) with microfertilizers (Siliplant (0.5 l/ha) or Cytovit (1.0 l/ha). As a standard, we used double foliar feeding with Siliplant (0.5 l/ha). The above-ground mass was mowed in the third ten days of August. On seed plantations we tested: in the early growth phase EcoFus (1.5 l/ha), in the stemming phase – growth regulators Epin-extra (0.06 l/ha), Agat-25K (0.04 l/ha) and their tank mixtures. Seed collection was carried out in mid-September.Results. Double spraying with complex – EcoFus with microfertilizers, promoted activation of growth processes, and it resulted in 22-26% increase of above-ground mass yield, 5-7% increase of phenylpropanoids in it, their collection per hectare increased within 28-35%. A more effective complex was revealed: EcoFus (1.5 l/ha) with Siliplant (0.5 l/ha), which allowed to increase yield and collection of active substances by 26 and 35% in comparison with the control, and in comparison with the reference (Siliplant 0.5 l/ha) – by 11 and 15%, respectively. In order to increase seed productivity of Echinacea purpurea, spraying with EcoFus at the beginning of vegetation of plants and EcoFus complex with bioregulators Agat and Epin-extra in the phase of stemming was applied. Foliar fertilization with these tank mixtures resulted in earlier flowering of plants (by 2-4 days), increased the number of inflorescences by 9-10%, inflorescences with seeds by 14-15% and seed weight of one inflorescence by 12- 14%. Activation of generative processes of Echinacea purpurea had a positive effect on seed yield and their quality: yield increased by 21-25%, weight of 1000 pieces by 7-8% and their germination by 2-3%.

Echinacea purpurea L. – is a perennial medicinal plant, from the herb of which dozens of preparations have been created that are used to strengthen the immune system, in the treatment of inflammatory diseases. At present, oxyconic acids and alkamides have been found in the plant’s root system, and the preparations «Anginol» and «Prostanov» have been created on their basis. The production and creation of new medicinal products from the roots and rhizomes of the Echinacea purpurea depends on a stable raw material base, which can be ensured by obtaining maximum yields of roots. As a result of studies to determine the timing of harvesting, methods to increase the yield of the underground mass in the conditions of the Krasnodar Territory, it was revealed that the high yield of roots and rhizomes of Echinacea purpurea was determined on plantations III-IV years of growing, which averaged 10 c/ha, they had an oxyconic acid content of 3,9%. In the future, there is a decrease in yield to 8 c/ha, and active substances to 2.1%. Dual treatments treatments Zircon (0.04 l/ha) and Siliplant (0.5 l/ha) both separately and in the mixture gave the opportunity to increase the yield for III and IV years to 28–30% and improve the quality of raw materials, the content of active substances increased by 5–7%. The complex use of these drugs in the V year of vegetation allows to increase the yield of roots to 10.3 c/ha with a high content of oxidic acids – 2.55%. It was revealed that foliar fertilization of vegetative plants with two-component system Siliplant + Zircon promotes the adaptation of Echinacea purpurea to dry weather conditions and makes it possible to obtain stable yields of medicinal raw materials with high quality regardless of weather conditions.
