Abstract: The purpose of the article was to analyze and summarize the results of previous long-term studies on irrigated lands in Ukraine. The necessity of restoration of irrigation in Ukraine is substantiated, taking into account the soil-reclamation state of the land for observing the requirements of preservation of resources, protection of soils and maintenance of the balance of natural processes. The scientifically grounded principles of survey of soil-reclamation state of irrigated lands inUkraine are proposed, whi… Show more

Purpose. To substantiate the concept of revitalization of regular landscapes of the exposition zone of the dendrological park of the State Biotechnological University. Methods. Field, laboratory, geoinformation, computer modeling (QGIS 3.28.3-Firenze 2022-08-31, Realtime Landscaping Architect 2023.02, Trial Free Version and Sketchup). Results. The historical context of the creation of the arboretum, the agro-ecological status of the elements of soil fertility, its trace element status, the ecological-ameliorative and ecological-toxic state were studied. The selection of introducers was carried out for the 5A climatic zone of winter hardiness (USDA-zone). Geoinformation modeling of the studied space was carried out, relief isolines were created. A revitalization project of regular landscape compositions of the exposition zone of the dendrological park has been developed. Taking into account the soil and climatic conditions in the formation of plant compositions requires the use of introducers that do not require a high level of available nitrogen compounds, but respond well to an increased content of mobile phosphorus and potassium, do not lose decorativeness when grown without irrigation or with the use of minimal soil protective irrigation, with high resistance against diseases and pests and will serve to increase the biological diversity of the urban landscapes of Kharkiv and other cities of Ukraine located in the 5th winter hardiness zone (USDA zone). Conclusions. It is proposed to preserve the approach proposed by the founders of the dendrological park, that is, to restore the decorativeness and expressiveness of plant compositions, but in the context of making nature-oriented decisions, to enrich this approach with an ecological feature.

The aim of the research is to establish the peculiarities of the formation of the nutrient regime of gray forest soil with different systems of basic cultivation, fertilization and sealing of by-products of crops in short-rotation 4-field grain crop rotation – winter wheat–corn for grain–barley–soybean. Evaluate the quantitative inflow of biomass, participation in the formation of the nutrient regime of gray forest soil, especially the differentiation of 0–40 cm of soil layer depending on the distribution of nutrients in different tillage soil systems. The studies were carried out in a long-term stationary experiment of the department of soil cultivation and weed control of the NSC «Institute of Agriculture of the NAAS», founded in 1969. The fertilization system consisted of the application of mineral fertilizers N65Р58К68 kg acting things per 1 ha of crop rotation area. As an organic fertilizer, we used by-products of crop rotation, where during 2009–2013 received an average of 5,17–5,50 t/ha, and 2014–2017 – 6,65–7,76 t/ha of crop rotation. The existing yield of the main product significantly influenced the volume of the non-commodity part, with the growth of the main product, the growth of by-products also took place in direct proportion. Nitrogen removal averaged 105 kg/ha, and with biomass it returned on average 55,4 kg/ ha, nitrogen with a full mineralization cycle, in general, this corresponds to 45–47 % of the share of costs. In general, the return of phosphorus from by-products for the rotation of 5 received an average of 12,0–16,7 kg/ha and 4-field crop 26 rotation 19,5–22,0 kg/ha, which was 35–40 % of the total removal harvest. The soil received many times more potassium from the biomass of agricultural crops than part of the cost of the main product, due to the attraction of the maize leaf mass, from which an average of 177–253 kg/ha enters the soil, and for crop rotation – 61,4–95,4 kg/ha per hectare of sown area. Key words: gray forest soil, soil nutrient regime, recycling of nutrients, main and by-products of crops.

Today, considerable attention is paid to the intensification of grain production, which depends on the accelerated introduction of highly productive varietal resources with the preservation of the properties of the variety in the process of further reproduction, the production of high-quality and competitive products for the sub-markets of pre-basic, basic, and certified seeds. Improved technologies for growing soft winter wheat should be based on the effective use of the soil and climatic conditions of the studied region, the biological, the genetic potential of varieties, technological innovations in agrotechnical methods of growing crops and the optimal use of material and technical resources. They should be effective for both the producer and the consumer of seed products. The purpose of the research was to determine the features of the formation of seed productivity and sowing qualities of soft winter wheat seeds, depending on the levels of mineral nutrition of plants in the Western Forest Steppe of Ukraine. The methodological basis consisted of general scientific and special research methods. Studies have established that with the low natural fertility of grey forest surface-gley soils of the Western Forest Steppe and considering climate change towards warming with a decrease in precipitation, the introduction of new more productive varieties of intensive type, complex forms of mineral fertilisers, microfertilisers, growth regulators into agricultural production, the questions of the nutrition system of soft winter wheat plants are insufficiently substantiated in this region. The research results presented in the article from 2019 to 2021 demonstrate the issues of the influence of the norm of application of mineral fertilisers with stage-by-stage feeding with nitrogen in different phases of organogenesis on the formation of indicators of seed productivity of varieties of the forest steppe ecological type of soft winter wheat. It was found that the rate of yield of conditioned seeds was the lowest in the control without fertilisers and grew by 16-20% for the application of mineral fertilisers. The seed yield varied from 1.58 t/ha in the control to 4.59 t/ha at the rate of N220P90K160S28, and the multiplication factor, respectively, from 6.3 to 19.8 units. According to this option, the total yield of the large and medium fractions was from 94.9 to 95.2%. A balanced complex of macroelements positively influenced the formation of indicators of sowing qualities of seeds, increasing the weight of 1000 seeds by 5.3-7.5 g, germination energy – from 4.8 to 8.4%, laboratory germination – from 13.6 to 14.4%
