Soybean is one of the most valuable protein crops on the modern market of agricultural producers and its production has been constantly growing in recent decades. The level of its productivity, as well as any other crop, depends on the biological productivity potential of the cultivated variety and the degree of implementation of its cultivation techniques. The aim of the research was to study the responses of soybean Glycine max (L.) Merr. Zusha varieties for various mineral nutrition in the conditions of agrocenosis. The research was conducted on the basis of the research and educational production center "Integration" of the Orel State Agrarian University named after N.V. Parakhin. We determined the biological efficiency of fertilizer systems, the productivity and quality of grain under different mineral nutrition conditions .Testing of liquid complex fertilizers on soy has shown high biological and economic efficiency of mineral fertilizers. In conditions of dark gray forest soils with average agrochemical indicators of the soil, as well as with spontaneous inoculation of soybean by native rhizobia strains, the maximum economic effect was demonstrated with the pre-sowing application of complex mineral fertilizer NPK (S)+Ca 5:15:30(5)+7 in a dose of 150 kg/ha and 20 kg/ha of urea, as well as diammofoski NPK(S) 10:26:26 (2) in conjunction with the ZhCU. The use of mineral fertilizers contributed to an increase in the growth of biomass by an average of 23%, and the area of leaves-by 8.5% compared to the control. Changes in mineral nutrition led to an increase in the content of raw protein in soy grains. Additionally, 4.4-4.6 C/ha of grain was obtained from 1 ha, respectively 4.7 and 5.4 thousand rubles of income due to an increase in soybean productivity by 22-23% compared to the control.

Arbosculpture in Russia is a developing art form. Nowadays there is a small number of works devoted to this topic in our country. In this regard, the aim of the following work is to study the technology of creating arbosculptures in the conditions of the central region of Russia. The material for creating arbosculptures are woody plants of the following species: Fraxinus excelsior L., Acer platanoides L., Prunus cerasifera Ehrh, Prunus cerasus L. The formation of sculptures takes 5 years or more. The process of the creation includes such stages as – making a sketch design, selection of a breed, planting a seedling (s), trimming, concrescence/ ingrafting, measures for the care and preservation of a given shape.

The authors of the article considered a relevant problem of using perennial plants in landscaping Russian cities in connection with their unique climatic conditions, existing traditions in landscaping and bad environmental conditions. For the natural and climatic conditions of the forest-steppe zone of the Russian Federation, a selection of perennial flowering plants that are resistant to the urban environment according to the criteria of low maintenance, shade tolerance, drought resistance and undemanding soil fertility has been carried out. When choosing perennial plants, the preference was given to the representatives of the local flora, large in height and stable for a long time in decorativeness. In this case it is possible to use the developed assortment when creating sustainable floral compositions in cities, meeting modern requirements of aesthetics, environmental friendliness and economy of the landscape objects. The design projects developed by the authors provide with the creation of modular flower beds of round, triangular, square shapes in the form of mixborders combined of large-sized flowering plants that easily fit into any configuration of the existing flower garden and are assembled by rhythmic repetition of the modules or their combination.
