    FEATURES OF ORGANIC AGRICULTURAL PRODUCTS FUNCTIONING IN EU AND UKRAINE
    (Visegrad Journal on Bioeconomy and Sustainable Development, 2019) Burliai, Alina; Burliai, Oleksandr; Nesterchuk, Yulia; Revutska, Alla
    Organic agriculture ensures a balanced state of the ecosystem, which is the key to sustainable development of the economic and social spheres of society. European countries are in the process of historical development reached an understanding on the need for its further ecological progress. That is why the world market for organic products has formed. Studies show that the development of organic production began in the 20‘s of the twentieth century. Since then, markets for organic products began to grow rapidly in many countries. Among the world‘s regions, the largest areas of organic land are located in Oceania and Europe. The article is devoted to the study of foreign experience in the development of ecological agriculture. The variety of names of ecological systems of management in the countries of the world and the principles which are included in the concept “ecological agriculture“ are studied. The history of the emergence of organic agriculture has been explored. The analysis of the development of organic agricultural production at the world level, the countries of Europe and the European Union (EU) and individual countries has been analyzed. A grouping of organic farms in Europe has been organized in terms of size. Ukraine, with its signifi cant natural and economic potential in the future may also be one of the important subjects that will form a proposal in this market. The environmental policy of the country has an important infl uence on the effi ciency of organic farms

    FEATURES OF SUNFLOWER OF STRAWBERRY DEPENDING ON ADAPTIVE GROWING TECHNOLOGIES
    (Dallas, USA:Primedia eLaunch, 2019) Karpenko, Victor; Burliai, Oleksandr; Nepochatenko, Oleksandr; Butsyk, Roman; Smertenyuk, Igor
    When growing strawberries, we must pay special attention and make the transition to less harmful technologies in order to obtain environmentally friendly products. This position minimizes the possibility of using mineral fertilizers or inorganic protection in favor of organic methods or substances of biological nature that do not have a harmful aftereffect. This is of particular importance when mulching the soil with various materials, as the most advanced method of increasing the productivity of strawberry stands. Therefore, the selection of the most adapted and improved technologies for growing environmentally friendly strawberries determines the purpose of our research. The highest results were achieved in the growth productivity of strawberries when it was grown using environmental technology with mulching the soil together with black agrofibre and straw. Moreover, the average results of the assimilation surface of strawberries amounted to 28.4 thousand m2 / ha for the Dukat variety, and 29.1 thousand m2 / ha for the Malvina variety. Such results practically exceeded the data of the control variant twice. A significant increase in the number of tendrils on the strawberry bushes was about 30%. At the same time, the number of peduncles in the bushes increased by 15%. On the whole, according to the experiment, the results for strawberry varieties varied within 6.7–7.3 pcs / bush. A significant difference compared with the control option was 1.4–1.8 pcs / bush. We have achieved a 35% increase in strawberry berries when mulching the soil with black agrofibre together with straw as part of environmental cultivation technology. On average, over the years of research, the strawberry yield for the Dukat variety was 21.5 t / ha, and for the Malvina variety - 15.5 t / ha. At the same time, commodity quality of berries increased to 93.4%. The use of intensive (traditional) and biological technologies for growing strawberries, in terms of productivity, was significantly inferior to environmental technology, like other mulching materials inferior to black agrofibre.

    Minimization of environmental risks in crops cultivation
    (Ukrainian Journal of Ecology, 2021) Burliai, Alina; Burliai, Oleksandr; Nesterchuk, Yulia; Cherneha, Inna; Sokoliuk, Sergiy; Osipova, Alla
    Environmental risks are urgent problems of today that require an immediate search for ways to minimize them. The leading cause of environmental risks is the anthropogenic factor associated with the economic development of society. Critical is the study of risks in agricultural production, on the development of which depends on the country's food security. This is because agricultural activities are closely intertwined with natural and climatic conditions. At the same time, agricultural enterprises also harm the environment, resulting in catastrophic climate change. The main environmental risks of agricultural production are identified: non-compliance with environmental standards; the emergence of epidemiological threats; risks of unfavorable natural and climatic conditions in the form of floods, fires, snow elements, and avalanches, icing, and risks of soil erosion (landslides); use of plant protection products; use of GMOs, reduction of production productivity through the introduction of environmental processes. One way to minimize environmental risks in agriculture is to optimize the structure of sown areas of crops. A model for optimizing an economic problem with two linear objective functions and a linear system of constraints is developed. The model contains a compromise solution on two indicators (gross output at comparable prices in 2016 (in order to reduce inflation) and the accumulation of carbon dioxide by cereals in terms of humidification subzones of the Forest-Steppe. Implementation of the optimization problem results will allow increasing the economic and environmental effects of grain production without unnecessary investments. Thus, the increase in the value of gross output in the region with specialization of grain production is 869,030 thousand UAH, and at the same time, the growth of CO2 accumulation in the amount of 3,714,918 tons, and taking into account the livestock industry to optimize the structure of grain crops can get an additional 477,297 thousand UAH VP and 1989363 tons of CO2.

    Production of alternative products and renewable energy sources in rural areas
    (Opole, 2016) Karpenko, Victor; Burliai, Oleksandr
    and renewable energy sources on the example of Ukraine is analyzed. It is found that that Ukraine is an energy-dependent country, and the main sources of energy con-sumption are fossil fuels. At the same time, the share of renewable energy sources in Ukraine is less than 2% which is one of the lowest indicators in Europe. However, we possess a massive unused potential for energy savings in the form of natural rene-wable energy and, in particular, there is a big potential of biomass available for energy production. Economically justified energy potential of existing biomass waste is about 25 million tons and the energy potential of biomass which can be grown on unused agricultural lands covering more than 4 mln ha – about 13 million tons (Table 3). Due to this potential we can cover up to 18% of total primary energy consumption in Ukraine. Thus, rural areas of Ukraine have a significant potential for bioenergy deve-lopment of the country.
