The urban factor affects not only the species composition of populations but also their absolute quantitative indicators. The purpose of the research was to carry out the floristic analysis of the characteristics of the meadow grouping of the recreation area, the structural analysis of the species composition of the phytocenosis, the identification of growth places of rare and medicinal plants, and the analysis of the development trends of this phytocenosis. The study of the floristic composition of the recreation area near the village of Sabariv in the Vinnytsia region was carried out by the expedition route method, as well as by using direct and indirect methods. The systematic belonging of plants was determined with the help of a designator. The abundance of species was determined according to the Gult-Drude scale (with the addition of A. A. Uranov and P. D. Yaroshenko). The article is a unique analysis of the species composition of plants in the recreation area near the village of Sabariv in the Vinnytsia region. 3 types of associations have been established: meadow slope, meadow lowland, and coastal. During floristic research throughout 2012–2020, a systematic analysis of the species composition was carried out: 39 species of plants belonging to 16 families were found in meadow slope associations, 37 species belonging to 17 families were found in lowland meadows, 25 species of plants belonging to 19 families were found in the coastal zone. The abundance of plants was calculated, and the participation of each species in the phytocenosis was determined. Medicine and rare plants were also discovered, in particular Pulsatilla grandis Wend., the place of growth of which has not been confirmed in recent years. The trends in the development of phytocenosis due to the increase in anthropogenic influence are described. In particular, a decrease in the participation of Campanula persicifolia L., Dianthus deltoides L. in meadow slope communities, and Alismaplantago-aquivatica L. in the coastal zone was revealed. Increasing anthropogenic load on this territory causes depletion of the species composition of natural flora. Therefore, it is necessary to systematically monitor the places of growth of rare and medicinal plant species, as well as to inform the population about the need for a careful attitude to natural resources in general and to raise awareness of the human impact on the environment.

At present, there are burning issues concerning waste utilization of the agro-industrial complex, rational usage of nature and transition to the use of environmentally friendly and low-waste technologies. One of the most forwardlooking areas is the application of the principles of the so-called "green chemistry", in particular, the development of technological processes using renewable raw materials and chemicals, the chemicals with a short half-life and low cost while ensuring maximum efficiency. The article presents the results of antigiberrelic preparation effect, which is characterized by low dosage and half-life in soil from 3 to 43 days on productivity, growth processes, anatomical, morphological features and functioning of the leaf apparatus of white mustard plants and rapeseed. The research shows that CCC-750 reduced the height of mustard and rapeseed plants. Inhibition of growth processes of white mustard plants at the beginning of the flowering phase with an anti-gibberellic preparation led to increased stem branching, which, in its turn, resulted in an increase in the number and area of leaves throughout the growing season. Moreover, the use of quaternary ammonium salt on winter rape plants has led to a reduction in the number of leaves and leaf area in comparison to the control samples. The application of the retardant caused an increase in the productivity of the studied cultures due to the increase in the number of pods, the increase in the mass of thousands of seeds and the number of seeds in the pod.
