In the article the results of the effect on Trigonella foenum-graecum L. productivity by organic fertilizers EcoFus and Siliplant and presowing inoculation of seeds with the Rizotorphyn are presented. We investigated effect of organic-mineral fertilizers "EcoFus" and "Siliplant" and presowing inoculation by "Rhizotorphyn". "EcoFus" and "Siliplant" increase herb yield by 24.8 and 18.8 % compare to control. "Rhizotorphyn" increasing yield of seeds production by 32.1 % compared to control. For the first time we present the data of the study devoted to the effect of foliar treatments with micronutrients and presowing seed inoculation on the quantitative content of flavonoids in fenugreek seeds. The highest flavonoid content was found in seeds subjected to foliar treatments with a binary mixture of "EcoFus + Siliplant" (1.59 %).

Background. For the comprehension the mechanisms of adaptation and increasing the bioproductivity of the Gypsywort, at the level of variability of micromorphological and anatomical features of the epidermis of the leaf plate and stem, it is proposed to study the reactions of plants to the use of micronutrients with adaptagenic properties. Scientific originality. For the first time in the conditions of crop rotation, the adaptogenic effect of the micro-fertilizer Siliplant on the plants of the Gypsywort at the degree of the epidermal structures of the leaf and stem was shown and confirmed. This work aim is to identify the morpho-anatomical features of Gypsywort, emerged as the result of exogenous treatment of plants with microfertilizer Siliplant. Materials and methods. The Gypsywort’s plants, growing in the conditions of field crop rotation at the experimental field, were treated in the budding by micro-fertilizer Siliplant (0.055 gallons per acre). The control variant was treated with water. The consumption of the solution was 32,07 gallons per acre. The research material was collected under the second-year plants during the mass flowering phase. Leaf plates of the middle part of the shoots (10 pcs.) were taken from plants (5 pcs. of each variant). The anatomical method of analysis included microscopy and microphotography. A 9x Ernst Zeits Wetzlar light microscope and a 14.0 Mp USB 2.0 C-Mount camera were used for the study. The sample consisted of 10 measurements, statistical processing of the results was performed in Microsoft Excel. For each studied trait, its average value (M), the error of the mean (m) and the coefficient of variation (Cv%) were determined. Results. The number and size of stomata were determined, the classification of trichomes was refined, their distribution, the density of pubescence and the number of essential oil glands were studied explored depending on the treatments of plants with Si-based microfertilizer. It has been found out that in plants growing in the field practically do not have hydathodes and pubescence increases. Conclusion. Treatment of plants with silicon Si-based microfertilizer contributes to their adaptation to xeromorphic conditions: pubescence decreases, the number of essential oil glands increases, the growth of the bark and xylem elements intensifies. The increased number of stomates and their sizes in the variant with silicon-containing microfertilizer, compared to the control samples indicates its anti-stress effect on the gypsywort plants. The established features of the anatomical structure of plants can also be important in determining the authenticity of medicinal raw materials of Lycopus europaeus L. plants during microscopic analysis.

For the first time the article presents data on the development of methods of vegetative reproduction of belladonna (division of rhizomes and green cuttings) to improve the efficiency of planting material. The method of optimization the breeding work will allow to receive homogeneous material of perspective samples of belladonna. Rooting of belladonna as a result of the use of growth regulators-rooters was: Zircon - 63%, Kornevin - 93%. When using a binary mixture of preparations Zircon and Kornevin rooting increased by 27% compared to the control. Survival of root cuttings of belladonna in the field in single-bud plants after treatment with Kornevin exceeded the control by 17%. The use of the root-forming agent "DvaU" is promising for vegetative reproduction of belladonna, since this drug provided almost 100% survival rate of plants and contributed to the strengthening of growth processes in the initial periods of plant growth.

Aim. The study of the phenology and seed productivity of golden root plants in the 2nd‐4th years of life in the Moscow region under the influence of meteorological conditions. Methods. The objects of research were plants of golden root from the biocollection of VILAR in Moscow. The studies included field and laboratory experiments, which conducted in 2016‐2019 according to methods adopted in medicinal plant production. Weather conditions in the Moscow region during the research period were identified on the Internet. Seed productivity was assessed according to generally accepted methods. Determination of seed sowing qualities was carried outaccording to National Standard 34221‐2017.Results. The influence of weather conditions on the passage of phenological phases of young golden root plants in 2016‐2019 in the Non‐chernozem zone of the Russian Federation under experimental field conditions was studied for the first time. The duration of phenological phases depending on conditions in the year of observation was determined. The composition of the population of young golden root plants for the second, third and fourth years of vegetation wasestablished. Adverse factors which reduce seed productivity and affect the quality of seeds were identified.Conclusion. The favourable meteorological characteristics of the growing season contributed to an increase in the mass of 1000 seeds by an average of 43 mg and increased seed germination to 82%. Differences in seed quality and productivity of seeds depending on the conditions of the year of observation may indicate the necessity for measures for adaptation of the plants to harmful environmental factors.
