The current condition of the former pesticide storages has been investigated and characterized. All pesticide storages of Kryzhopil region are in extremely poor condition and they contain substantial amounts of unknown mixtures of unusable pesticides, which are stored in bulk in 100% of pesticide storages being a powerful source of environmental pollution by toxicants of various chemical composition. Pesticide residues in different environment (soil, water, plant) have been determined. The research results clearly prove availability of severe local sources of contamination of agricultural lands with organochlorine pesticides. There is a risk of contamination of other environmental objects with hazardous substances and a negative impact of toxic substances on human health. Migration of pesticides from the soil into agricultural products and drinking water has been identified. It has been suggested that poor environmental conditions and consumption of pesticide-contaminated agricultural products and drinking water lead to an increase in the number of human diseases. It has been found that the population of the district has much higher morbidity rates compared to the indicators of the oblast. Step-by-step environmental risk assessment has been carried out.

Annual aster, also called China aster (Callistepsus chinensis (L.) Nees) is one of the priority ornamental flower plants for the introduction both in Ukraine and throughout the world. Domestic and foreign scientists are diverse in the study of this plant. Most of the works published during the last decades are devoted to the study and search for the most favorable agrotechnical techniques for aster cultivation under different conditions. The research was being carried out during 2016‑2017 on the territory of the Bio-stationary of Vinnytsia National Agrarian University with partial subsequent data processing at Bila Tserkva National Agrarian University. The purpose of the study was to identify the most adapted and resistant samples among the collection cultivars of China aster for their further breeding and greening of various objects of Vinnytsia region. The methods of field and laboratory research were applied in accordance with the basic methodological requirements. The prospects of growing cultivars of China aster (Callistepsus chinensis) in the green space of Vinnytsia region were analyzed. The demand for new cultivars of different groups of annual aster in ornamental gardening and the need to develop decorative cultivars resistant to diseases and adapted to the environment was proved. For the first time, biomorphological features of Chinese asters (Callistepsus chinensis), methods of reproduction and the most promising cultivars for their growing under conditions of Vinnytsia region and their further use in landscaping of various objects were investigated. A collection of cultivars of different groups of Chinese aster on the territory of the collection site of Vinnytsia National Agrarian University was produced and unified. Due to high ornamental qualities, economic and biological qualities of the studied cultivars, all of them are evaluated as well adapted to the edaphic and climatic conditions of Podillya and they are recommended as objects intended for the replenishment of the assortment of plants for greening, collection and exhibition funds as well as breeding activities. A diversity of colours and forms of inflorescence, various shapes and height of the bush enable to use China aster widely in the single linear plantations, group plantations, for the arrangement of mixborders and plant beds, on the rocky landscapes and borders, to create groups and flower beds.

Global climate change has mainly impacted the forest ecosystems in Europe. Today, it is not fully understood how these changes will affect the reproductive process of trees on seed orchards. The main aim of the study is to evaluate the growth, condition and reproductive function of Scots pine clones of Finnish origin after moving them to the southern direction of natural distribution area. Variability and seed productivity of 25-year-old clones of Scots pine of Finnish origin in the clonal seed orchard under climatic conditions of the central part of Ukraine (Vinnitsa region) was investigated. Grafted seedlings of Scots pine of Finnish origin were moved southward at a distance of over 1,500 km. Climatic conditions of Vinnytsia region, where the clones were displaced, differed by an increase in the mean and maximum temperatures by 3.3–3.6ºC, as well as an increase in the mean temperatures during the cold period and a rise in the minimum by 2.1–2.3ºC. The climate in the seed orchard location was characterized by the most significant increase in the mean temperatures in April and May (5.3–5.8ºC), which greatly influenced the intensity of the formation of microstrobili and macrostrobili. The ratio of precipitation to the amount of temperatures decreased more than twice. Analysis of the grafted trees’ vitality of Finnish origin and seed progeny of the local population, estimation of their intensity (height, diameter), state (category of the state) and reproductive processes (intensity of formation of microstrobili and cones) was carried out on the clonal seed orchard. In conditions of climate change, most of the clones of Finnish origin were characterized by a higher intensity of flowering compared to the local population. Some clones of Finnish origin (E80 and E729) dominated the local population by the seed yield. According to a comprehensive analysis of vitality, the intensity of growth and reproductive capacity, the best clones of Finnish origin were E80, E1883 and E2254. Low adaptive ability was noted in the clones E2312, K634 and K801. According to the research results, it was found that changes in climatic conditions did not significantly affect the vitality, development and condition of the clones. There was observed intensification of the formation of microstrobili and cones. Seed viability and quality of Scots pine of Finnish origin obtained on seed orchards located in the southern conditions requires further research.

The article examines the relevance of topiary art in modern landscape design. The art of topiary requires a well-thought-out compositional integrity. Before choosing plants, you should decide on the theme of the garden and the harmonious arrangement of topiary figures in it. Such compositions become an adornment of any backyard territory, giving it an aristocratic exclusivity and originality. A detailed taxonomic analysis of the assortment of plants, which were used to form topiary on the territory of Vinnytsia National Agrarian University and the botanical garden "Podillya", was carried out. The state of the existing topiary figures was assessed. The features of the formation of topiary figures by the classical and wireframe formation technique have been investigated. Of the plants of the classical formation technique, a spiral figure has an excellent appearance. The hedge, cone and column shape have a good appearance. Plants formed in the form of a circle have the lowest indicators of external perception. The frame technique for creating plant compositions prevails at the VNAU exposition area. Project proposals have been developed to improve the aesthetics and general appearance of topiary figures on the territory of the Vinnytsia National Agrarian University. For the plant to have an attractive appearance, appropriate care is needed. Pruning of plants (sanitary) should be carried out only during the dormant period. The best period will be the end of winter, when the threat of severe frosts has passed. In the spring, no later than the first half of April, the first corrective pruning of figures and hedges should be carried out. In the summer, several additional haircuts are made, the frequency of which depends on the intensity of growth. It is optimal to carry out an additional haircut 3 months after the first one. In summer, you do not need to cut in extreme heat. Haircuts are finished before the onset of the first frost. If you carry out the formation later, then the created topiary will simply freeze over. In the cold season, some figures, especially those created from conifers, can fall apart under the weight of snow, so it is advisable to tie them up.
