Analysis of yield and essential oils formation on clary sowings in the conditions of the south of Ukraine

The aim. The purpose of the article is to analyze the state of growing musk sage in Ukraine, the use of medicinal plant raw materials of guaranteed quality, as well as the principles and rules of good practice for the production of herbal medicines in accordance with GMP requirements, which highlight the requirements of standardization for medicinal plant raw materials and basic indicators of their quality. Material and methods of research. The rates of mineral fertilizer application under the plow are determined and the basic tillage of the soil is carried out at a depth of 20–22 and 28–30 cm. The determination of the sowing dates of muscat sage, the width of its rows, the terms of harvesting raw materials has been determined. To maintain moisture in the soil during the responsible period of development of plants, we conducted research on the use of Radchenko harrow with breeding segments from the scythe of the unit ZhVN-6, which well weed out weeds from the soil and retained moisture in the soil at 75 % N.V. Results of researches. The conducted researches have established that products of photosynthesis in Muscat sage are deposited in the root roots, in which up to 35 % of sugars are accumulated in the winter, mainly in the form of sucrose. If during the passage of the first phase of tempering (October) in the rod root there are slight changes in the content of sucrose, then with a decrease in air temperature to minus 8–10 °C, there is a sharp increase in the content of sucrose. So, if in October in the root roots contained 16,55 sucrose, then in January – 28,19. In February, the amount of sucrose is reduced to 22.58. At this time, the content of monosaccharides falls to 1.40 versus 12.75 % – in October. In the usual cultivation of the cultivator KRN-4.2, the acclimativeness of the weed plants was up to 40, when applied technology with Radchenko harrows up to 15 %. Discussion. Yes, E. Tkacheva notes that this depends not only on the request of the companies-purchasers, but also on the term of storage of raw materials. The point is that the way of use of medicinal plants depends on the characteristics of biologically active substances that are contained in plants. The content of biologically active substances in plants and in their various organs is inconsistent, depending on the conditions of the place of cultivation, time of day, weather conditions and a number of other factors that are no less important. Conclusions. Thus, for the first time in the conditions of irrigation of the south of Ukraine during the three years of sowing, agronomic techniques for growing muscat sultana, norms for introducing mineral fertilizers for basic tillage, plowing depths, seedlings, and their aftermath to form the phenological phases of plant development were studied at different years of life on the yield of raw materials, and the content of essential oil in it. Key words: Muscat sage, depth of plowing, dates of sowing, fertilization, row spacing, harvesting terms.
