The importance of increasing the level of renewable energy sources is connected with the fact that its share in the total volume of energy consumption is still insufficient. This is why this article focuses on the development of the motivation system aimed at the more active transition to renewable sources consumption in the balanced combination alongside the traditional sources. The research question is whether digital public goods (DPG) may be a mean to support “Affordable and Clean Energy’’ use. The theoretical approach to our research problem is stakeholder’s theory, while the concept applied to the motivation mechanism implementation is the United Nations Organization’s concept of sustainable development goals (SDG). The research design is as follows: study of the actual data of energy structure of the world economy; identification of the current instruments of renewable energy distribution; analysis of the DPG as a perspective form of the sustainable energy behavior introduced [AO1] in the digitalized environment; definition of the energy industry stakeholders; development of the architecture of energy consumption by DPG application to reach SDG “Affordable and Clean Energy”. The main findings of the study are that DPG has been found to be a relevant means for the motivation and support of sustainable energy behavior through the architecture of energy consumption, based on research and development, customer relationship management, corporate social responsibility – sustainable development, technical implementation, and the diversity of traditional and alternative sources of energy.

Znaczenie zwiększania poziomu OZE wiąże się z tym, że ich udział w całkowitym wolumenie zużycia energii jest wciąż niewystarczający. Dlatego w niniejszym artykule skupiono się na rozwoju systemu motywacyjnego ukierunkowanego na bardziej aktywne przejście na zużycie ze źródeł odnawialnych w zrównoważonym połączeniu obok źródeł tradycyjnych. Pytanie badawcze brzmi: czy cyfrowe dobra publiczne mogą być środkiem wspierającym korzystanie z „niedrogiej i czystej energii”? Teoretyczne podejście do naszego problemu badawczego to teoria interesariuszy, natomiast koncepcja stosowana do wdrażania mechanizmu motywacji to koncepcja celów zrównoważonego rozwoju Organizacji Narodów Zjednoczonych. Projekt badań jest następujący: badanie rzeczywistych danych dotyczących struktury energetycznej gospodarki światowej; identyfikacja obecnych instrumentów dystrybucji energii odnawialnej; analiza cyfrowych dóbr publicznych jako perspektywicznej formy zachowań związanych ze zrównoważoną energią wprowadzaną w zdigitalizowanym środowisku; definicja interesariuszy z branży energetycznej; opracowanie architektury zużycia energii przez aplikację DPG w celu osiągnięcia celu zrównoważonego rozwoju „niedrogiej i czystej energii”. Główne wnioski z badania są takie, że cyfrowe dobra publiczne zostały uznane za odpowiedni środek motywowania i wspierania zrównoważonych zachowań energetycznych poprzez architekturę zużycia energii, opartą na badaniach i rozwoju, zarządzaniu relacjami z klientami, społecznej odpowiedzialności biznesu – zrównoważony rozwój, realizację techniczną oraz różnorodność tradycyjnych i alternatywnych źródeł energii.

The article reveals the role of soybean varieties and the value of their crops, capable of fixing atmospheric nitrogen and being a favorable predecessor in modern crop rotations, the importance of optimizing organo-mineral nutrition, seed treatment with nitrogen-fixing and phosphate-mobilizing bacteria for improving the nitrogen-fixing capacity of soybean varieties. Development of the technology of growing soybeans with environmentally friendly elements requires scientific substantiation and adaptation to the soil and climatic conditions of a particular growing zone, as well as the research of their impact on the varietal characteristics of a crop. The research outcomes conf irmed the maximum formation of the symbiotic apparatus indicators: the number and weight of soybean nodules and their intensive functioning with the formation of the highest indicators of the total and active symbiotic potential as well as the amount of biologically fixed nitrogen, it is necessary to jointly inoculate seeds with Rizoline and double application of chelated microfertilizers at microstage BBCH 12-13: Organic Balance+Azotophyte+Helprost Soybean+Liposam and at microstage BBCH 61-69: Organic Balance+Azotophyte+Helprost Boron+Liposam. At the same time, the total number of soybean nodules was formed in the Samorodok variety−50.3, of which 36.0 pcs./plant were active, in the Amadeus variety–55.6 and 40.0 pcs./plant. The total and active weight of soybean nodules in the Samorodok variety made up 515 and 399 mg/plant, and in the Amadeus variety–586 and 454 mg/plant. Indicators of total and active symbiotic potential were 31.2 and 21.6 thousand kg/day per ha in the Samorodok variety, as for the Amadeus variety–36.5 and 25.5 thousand kg/day per ha and biologically fixed nitrogen in the Samorodok variety–119.0 kg/ha, in the Amadeus variety-140.1 kg.

In the current conditions of intensification of grain production, it is important to develop resource-saving cultivation technologies that ensure the maximum realisation of the genetic potential of crop varieties through the use of foliar fertilisation and mineral fertilisers. The article presents the results of research on the optimisation of fertilisation of spring barley plants. During the period of research, the influence of fertilisation and foliar feeding on the germination and preservation of spring barley plants, net photosynthetic productivity, elements of the yield structure, yield and grain quality was assessed. The research was conducted in the experimental field of Vinnytsia National Agrarian University during 2018–2020 on grey forest medium loamy soils. The hydrothermal conditions were quite contrasting and differed from the average perennial conditions both in terms of heat intensity and moisture level, which allowed to study the influence of the studied factors and their interaction on the formation of spring barley yield and grain quality. The maximum indicators of plant preservation, net productivity of photosynthesis, elements of crop structure, yield and grain quality were obtained in the experiment variant with the combined application of mineral fertiliser at a dose of N30P30K30 and foliar feeding of plants with Vuksal microfertiliser (BBCH 33-51) and (BBCH 51-54) in Aizhan and Aristey varieties. With the application of mineral fertiliser at a dose of N30P30K30, the grain yield of spring barley varieties Aizhan and Aristey increased by 0.99; 0.85 Mg·ha-1, and the protein content by 1.9; 2.0% compared to the control variant. With the combined application of mineral fertiliser at a dose of N30P30K30 and foliar feeding of plants with Vuksal microfertiliser, grain yield increased by 1.54; 1.23 Mg·ha-1 for one-time foliar feeding; by 1.77; 1.42 Mg·ha-1 for two-time foliar feeding, and protein content by 2.8; 2.7 and 3.4; 3.3% in Aizhan and Aristey varieties compared to the control variant, respectively.
