The analysis of the elemental composition of the raw material of the Stevia rebaudiana plant was carried out. The Stevia rebaudiana plant is able to regulate the intake of heavy metals, which allows them, on the one hand, to actively resist excessive consumption of toxic substances, and on the other hand, selectively accumulate essential elements. The content of essential elements in the composition of plant raw materials, regardless of the growing conditions, does not exceed the permissible limits.

During the study, using the instrumental neutron activation method, the content of macro- and microelements (Mg, K, Mn and Se), possessing significant biological activity in medicinal plants of South Ferghana, based on them, a medicinal collection was created, used in the prevention and treatment of diseases of the cardiovascular system. A large number of bioelements in the collection, as well as a small accumulation of toxic elements (Cd, Sb, Ba, Hg and As) allow it to be used in the treatment of various bioelements.

The article describes the work of a number of scientists of the Russian Federation on the effect of rye on the structure of the crop, the timing of its sowing and the rate of fertilizer application. In our experience, it was noted that some elements of the crop structure decreased due to plant deposition, with an increase in the rate of mineral fertilizers when sowing rye in the early (1.10) terms under the conditions of Vakhsh 116 variety. We see that the mid-season sowing options are higher than the early-ripening and late ones. The lowest indicator for this variety was observed in late (1.11) varieties of sowing. In the Waterfall variety, plant dormancy was observed relatively rarely and did not adversely affect some elements of the crop structure. The sowing date for both varieties is October 15, and the rate of mineral fertilizers was high when N180P110K90 kg/ha was applied.
