The results of researches of influence of biological preparations on biometric parameters of plants and productivity of table beet are resulted. The influence of biological preparations on the phases of growth and development of table beet plants, its yield and biometric parameters of products is established. Treatment of plants with the biological complex Organic Balance + Azotophyte + Liposomes accelerated the phenological phases of growth and development of table beet plants. As a result of measuring the height of plants, an increase in control over the treatment of plants with biological products was detected, in particular in the variety Red Ball Organic Balance + Azotophyte + Liposam provided an increase of 1.0 cm relative to control. The increase in plant height in the Pablo F1 hybrid was 2.2 cm with the use of Organic Balance + Azotophyte + Liposam. The largest number of leaves was observed for the treatment of plants Organic Balance + Nitrogen + Liposomes: in the variety Red Ball growth relative to the variant without treatment was 2.3 pcs / plant, in the hybrid Pablo F1 - 2.8 pcs / plant. Treatment of plants Organic Balance + Azotophyte + Liposam contributed to an increase in leaf area by 0.09 dm2 / plant in the variety Red Ball, 0.22 dm2 / plant in the hybrid Pablo F1. The use of Humifrend + Azotofit + Liposam also contributed to the increase of this indicator with an increase relative to the controls of 0.06 and 0.15 dm2 / plant, respectively. The influence of biological preparations on the biometric parameters of plants was established in the phase of intensive root growth. The largest biometric parameters in the phase of intensive root growth were recorded during the treatment of plants Organic Balance + Azotophyte + Liposam. In particular, the height of plants treated with Organic Balance + Azotophyte + Liposam increased by 2.2 and 3.1 cm compared to the untreated options. A slightly smaller increase in this indicator was recorded for treatments of plants Humifrend + Azotofit + Liposam - 0.8 and 1.0 cm, respectively. The number of leaves also increased during the treatment of plants with biological products. In the Pablo F1 hybrid, this figure was higher than the Red Ball variety - 16.0 - 18.7 units / plant. The use of Organic Balance + Azotophyte + Liposam provided an increase in the number of leaves by 2.8 pcs / plant relative to control, for the treatment of plants Humifrend + Azotophyte + Liposam increase was 1.8 pcs / plant. The positive effect of the use of biologicals was observed taking into account the area of leaves. With the use of Organic Balance + Azotophyte + Liposam, this figure in the studied varieties and hybrids increased by 0.8-1.3 thousand m2 / ha, respectively, compared with the control. Slightly less growth of this indicator was observed for the treatment of plants Humifrend + Azotofit + Liposam 0.3-0.7 thousand m2 / ha, respectively. The highest indicators of biometric parameters of plants were observed in the hybrid Pablo F1 for plant treatment Organic Balance + Azotophyte + Liposam, where the increase in plant height was 0.7-1.2 cm, the number of leaves - 1.8-2.1 pcs / plant, leaf area - 0.8-1.1 thousand m2 / ha, respectively. The highest yields were recorded with the application of Organic Balance + Nitrogen + Liposomes: in the Red Ball variety the increase was 7.1 t / ha, in the Pablo F1 hybrid - 10.3 t / ha relative to control. A positive effect was also obtained with the application of Humifrend + Azotofit + Liposam, where the increase was 4.9 and 8.4 t / ha, respectively. Treatment of plants with a complex of biological preparations Organic Balance + Azotophyte + Liposam provided an increase in root mass in the variety Red Ball - 45 g, in the hybrid Pablo F1 - 30 g, respectively. During the treatment of plants Humifrend + Azotofit + Liposam the increase was 30 g - variety Red Ball and 25 g - hybrid Pablo F1. Indicators, the diameter of the root crop was in the range of 8.4 and 9.0 cm. 5 cm. The increase in root diameter with the use of Humifrend + Azotofit + Liposam was slightly smaller and amounted to 0.1-0.3 cm. plants Humifrend + Azotofit + Liposam contributed to an increase in this indicator relative to control by 0.3-0.2 cm

This article analyzes the main problems of use and compositional application of different types of magnolias in Vinnytsia. In the research material of the article we conducted an analytical review of the species diversity of magnolias. We found that most acclimatized species are highly decorative, the highest rate of decorativeness is characteristic of Magnolia Soulangeana Soul. (48 points), and the lowest in Magnolia obovata Thunb. (46 points). As a result of research it was found that the range of magnolias in Vinnytsia is very poor and is represented mainly by such species as: Magnolia kobus D.C., Magnolia obovata Thunb., Magnolia Soulangeana Soul., Magnolia acuminata L., Magnolia tripetala L.; It is investigated that in the compositional application of magnolias are used in Vinnytsia mainly for single or group landscaping of buildings; As a result of research, it was found that due to their morphobiological, ecological properties and decorative qualities, the possibilities of using magnolias can be much wider and knowing their winter hardiness, you can use a wider range of species in our conditions. It is established that less decorative, but more stable species are used for street landscaping (M. kobus DC, M. kobus Sarg. Var. Borealis., M. x loebneri Kache., M. acuminata L., M. salicifolia (Sieb. Et Zucc.) Maxim., M. x kewensis Pearce., M. biondii Pamp., M. cylindrica Rehd. Et Wils., Etc.). We have found that the most popular varieties of magnolia are Betty, Merril, Lennei. According to the results of the study, we found that the lowest prevalence rate is characteristic of Magnolia Loebneri "Merrill" (7%), and the highest in Magnolia x soulangeana "Lennei" (14%). It is established that these varieties have a number of advantages, among which it should be noted: plants are suitable for growing in Ukraine almost everywhere, cold- and frost-resistant; compact, characterized by slow growth; flowers have a decorative look, long retain freshness, are characterized by a wonderful aroma.

The article presents the data of the analysis of science-intensive literary sources with the definition of world and domestic experience of rose cultivation for the purpose of further prospects of use in landscaping of the park zone of Vinnytsia National Agrarian University. The main task of the research was to carry out modern analysis of available scientific information and generalize information about historical aspects of distribution, morphological and biological features of these plants on the basis of architectural and exposition area of botanical garden «Podillya» Vinnytsia National Agrarian University with new garden groups, their introductory decorative and valuable cultivars suitable for introduction into culture, and also for use in selection work. The high decorative characteristics of roses and wide possibilities of their application in horticulture are taken into account, which provided grounds for the development of recommendations for replenishment of the collection in the landscaping of Vinnytsia National Agrarian University. The topical issue of expanding the options for the use of roses, which would have a high degree of decoration, different flowering times in the Podillya zone, is outlined. According to the results of the survey of flower agrocenoses of garden and park objects of the Podillya zone, it is established that the range of culture is represented by about 300-400 species of roses and 6000 varieties belonging to different garden groups. It has been established that among the studied roses such garden groups as Floribunda of the Arthur Bell variety, park roses of the Leonardo da Vinci variety, tea-hybrid roses of the Angelica variety have become widespread in many countries of the world and Ukraine. Thus, thanks to the creation of a rosary, as well as the expansion of their garden compositions, their more uniform placement in the park area of Vinnytsia National Agrarian University, will significantly bring the landscaping of Vinnytsia, as the most attractive cities in Ukraine to the best world standards. The processed data of the experimental work will be used in the development of recommendations for the creation of a rosary on the basis of the architectural and exhibition area of Vinnytsia NAU and to improve the practical activities of students majoring in 206 «Horticulture» and research and teaching staff.

According to the conducted comparative-literary analysis of scientific sources on studying of foreign experience of cultivation of species of the genus Syringa L. the design decision of a monocultural garden of a lilac on the basis of arboretum «Ladyzhinsky hay» is created. The analysis of the condition of the existing plantations of the arboretum, which is used by the Ladyzhyn City Council, is carried out and the potential possibilities of forming a monocultural lilac garden are assessed. The main result of the work is a scientifically sound project decision on the formation of a recreational area with elements of the dendrological plan of the site «Ladyzhinsky hay», as well as an explanatory note with project solutions for landscaping and landscaping of the studied arboretum. Scientific and experimental studies were performed on the basis of processed and analyzed materials of park management in the dendrological park «Ladyzhinsky hay» in Ladyzhyn, Vinnytsia region, in particular, existing planting plans, descriptions and photos, as well as on the basis of own field research. The selection of the range of plants in accordance with the edapho-climatic conditions of the region, as well as taking into account the specifics of the allotted area. The recommended selection of plants will enrich the color scheme of the monoculture garden of lilac by introducing ornamental flowering shrubs from the most characteristic members of the genus Syringa L. The balance of the site № 21 (92% of the total area), the lawn will cover an area of 1100 m2 (5% of the total area), 3% of the total area (600 m2) will be allocated for the area of paved paths.

It was selected and proposed for use in the gardening industry data types of plants that received high indicators of economic and biological characteristics: Calamagrostis acutiflora Roth., Miscanthus sinensis Anders., Phalaris arundinacea L., Stipa pulcherrima L., Cordaderia selloana Schult., Festuca glauca L., Mentha spicata L., Rosmarinus officinalis L., Thymus serpyllum L., Salvia splendens, Sellow ex. Shult., Melissa officinalis L., Lavandula angustifolia Mill, according to the results of research of existing and introduced ornamental grasses and aromatic herbs in Vinnytsia region. After comparative analysis of plants at certain stages of development, the estimation of periods of the highest decorative value is presented. For cereal herbs, this period is prolonged and falls on summer-autumn (Cortaderia selloana, Calamagrostis acutiflora and Miscanthus sinensis). The highest level of aroma is the fragrant herbs released on the sunny days of summer, when essential oils are more intense (Salvia splendens, Melissa officinalis, Lavandula angustifolia). Based on generalized data on the morphological characteristics of the investigated plant species, the potential seed yield of the studied species was determined. It wasestablished that the decorative herbs in the conditions of the study formed a viable seed with high seed productivity - 22,0 ± 2,3 seeds per generative shoot in Festuca glauca to 372,0 ± 2,34 in Calamagrostis acutiflora. nasinnyefikatsiyi factor in the studied conditions ranged from 17,2% in Rosmarinus officinalis to 95.6% in Cortaderia selloana. It has been established that all studied species are successfully used in landscaping: in mixburders and plant groups, the vast majority of them are used in clubs. Premature forms of ornamental grasses are used to create saltines, low-growing, shale grasses and fragrant grasses are preferred when creating stone slides, and curbs are laid based on shrub and semi-cultivar low or medium-sized investigated species of plants.

According to the results of researches of decorative species Lupinus L., it was established that under conditions of Podillia the most promising are perennial lupins (L. perennis L.) and lupine multifilament (L. Polyphyllus Lindl.) For planting of different objects. For the creation of modern garden compositions of the park zone of Vinnytsia National Agrarian University the most expedient to use are varieties: Lulu-Rasel, Minaret, Albus, Feerverk, which are very well adapted to the conditions of cultivation, practically not affected by pests and diseases, were sufficiently resistant to adverse environmental factors. According to the study of the flowering phase, it was found that the highest values of flowering time (up to 60 days) were observed in perennial lupine plants (60-day-old Feerverk and 55 days Albus variety). Somewhat lower values were recorded in lupine multiflorous plants (Minaret type – 45 days, hybrid Lulu-Rales – 44 days). In determining the suitability of the plants we studied for their use in landscaping, their evaluation was carried out according to the complex of economic and biological indicators in accordance with the State methodology of variety testing (Albus – 99 points, Feerverk – 98 points, Minaret – 95 points, Lulu-Rasel – 94 points). Their high score on the set of criteria indicates the prospect and suitability for cultivation in the Podillya, as well as the value for various uses: flower beds, mixborders, landscape composition compositions and their reduced variants imitated by natural groupings.
