Agroecology represents a pertinent option to improve the sustainability of agriculture. To promote its application, agroecological concepts should be taught to students and professionals in the agricultural sector. However, most agricultural courses are not adapted to teach these concepts due to little interactivity or interdisciplinarity, and a lack of a systems approach to farm management. Serious games help to fill these gaps by simulating complex models in which players can learn by doing. We thus developed a serious computer game, called SEGAE (SErious Game for AgroEcology learning), which represents a mixed crop-livestock farm and assesses impacts of farming practices on indicators related to environmental, economic, and social sustainability. Its pedagogical interest was evaluated through two types of surveys given to university students who played the game during a one-week workshop: A knowledge survey on agroecology, and a feedback survey based on flow theory. Results showed that students increased their knowledge of agroecology significantly, particularly those who had had little knowledge of crop production. More than 86% of the students enjoyed the game, appreciating its interaction and feedback. Thus, SEGAE is an interesting tool to help students acquire knowledge of agroecology in a fun way by facilitating interdisciplinary and collaborative learning.

The paper presents possibilities for the use of OTR-7 software (Organizer of Agricultural Technology) for optimization of the machinery park equipment in sustainable agriculture. The applied algorithms enable selection of the relevant technical equipment which enables performance of the planned field work. Due to the use of the specialised software, desired economic effects and competitive advantage can be obtained and the risk related to the purchase of expensive equipment can be minimized.

Issues of environmental security, fuel and energy independence have been forming political and economic territories for several centuries. Current events in Ukraine have become a litmus test, which clearly highlights the dangers of resource monopolies and the transfer of economic benefits. The issue of ensuring the energy system in climate neutrality became relevant even before the aggression by Russia. However, today, there is no country, it has not recognized that there is the urgent need to develop and implement effective tools for economic development in a sustainable environment. The modern cost-oriented model of knowledge of economic processes has led not only to the irrational use of natural potential. Large-scale use of natural resources and the irrational organization of production (including agricultural) disrupt the process of their reproduction, which, in turn, leads to the depletion of bioresources and, as a consequence, can lead humanity to ecological catastrophe. Certain solutions have been proposed to address these issues. To ensure the efficient use of the resources of the agricultural sector and the reliable reflection of biological processes, it is proposed to recognize the biological form of capital as self-growing and self-reproducing value, which, in the process of biological transformation, allows obtaining an additional unit of benefits. The study examines, in detail, the promising areas of the transformation of the agricultural sector in the framework of a technologically integrated European Green Deal in the EU. In this study, to determine the potential opportunities for the ecological transformation of agriculture, discrete analytical models of the assessment of the agro-industrial complex of Ukraine were used. Representative data use statistical indicators of Ukraine and, to illustrate potential opportunities, present a comparison of export data to EU countries. In addition, it reveals the realized and potential opportunities of Ukraine’s entry into the European market through the prism of the implementation programs of EU environmental policy. The place and significance of assimilation potential for a reduction in the anthropogenic impact on the environment, and providing the self-restoration of natural resources, are substantiated. It is determined that one of the most effective tools for low-cost reduction in greenhouse-gas emissions is the national-level implementation of environmental-quota trade and the development of organic production. The study includes an analytical assessment of the expected emission reductions from environmental initiatives’ implementation. Prospects for further research are the development of an effective mechanism for the systematic management of the biological potential reproduction of the agricultural sector while reducing anthropogenic impact on the environment.

Motivation: Knowledge management is currently one of the most important factors determining the company's market position. It depends not only on the skilful use of re- sources, but also on obtaining a synergistic effect. To manage knowledge, managers must possess not only the appropriate resources of knowledge, but also must have determined management structure with the assistance of the IT (information technology) tools. Aim: The purpose of the article was to present how the modern enterprise knowledge management process is supported by information technology. For this purpose, was summarized selected indicators characterizing the use of ICT in various types of enterprises in the country. It assumed that it is important not only the equipment the companies with information technology tools, but also the degree of use of these tools. Results: Usage of ICT in Poland reaches ratios much lower than the average for the European Union. Large differences in the use of information technology occurs in individual groups of companies. Larger companies have reached a much higher degree of saturation of IT tools than smaller objects. For example, the number of Polish enterprises with computers was 94.7%, in the case of large companies it is 99.8%. Even greater discrepancy relates to access to the Internet. You may also notice differences in each province. Introduction of modern technologies related to computer science and computers (eg. cloud computing, big data, social media, e-commerce etc) enables effective knowledge management in companies. The indicators show that the management team appreciates the importance of knowledge and consistently invests for its development.

The objective of the paper is to present methods of evaluation of real estates used for evaluation of agricultural equipment and types of value related thereto. Alina carrot harvester by Waremczuk company served as an example, for which a detailed methodology and the results of valuation were presented.Evaluation was carried out based on two approaches namely a comparative and cost approach. In the case of the comparative approach, the average price adjustment method was used and in the case of the cost approach - a replacement cost method.As a result of using various approaches and methods of evaluation two slightly different values of the evaluated harvester were obtained. It was respectively: EUR16,406 - at the use of the average price adjustment method and EUR 17,678 - the estimated net replacement value in the cost approach for the replacement method.

A correct selection of the machinery park is vital for correct functioning of a farm. It is significant in sustainable farming where, except for economic factors, application of a suitable technique and technology in order to lead an effective production is crucial. The paper presents a method of designing a set of machines for a farm. The method was implemented in the computer application. A suitably selected, optimised machinery park enables a sustainable agricultural production and achievement of the desired economic, production and environmental effects. The application was practically verified and is used in teaching and farming practice.
