The purpose of the study is to analyse the economic efficiency of milk-producing enterprises (on the basis of the IMK agricultural holding) and search for ways to increase their competitiveness based on the adoption of optimal management decisions. During the research, general scientific and special methods are used, such as: dialectical, systematic approach, abstract-logical, analysis, synthesis, graphic presentation, grouping and generalization. It has been proven that the assessment of economic efficiency is an important tool for researching the financial and economic status, competitiveness, investment attractiveness and ensuring rational management of an agricultural enterprise engaged in milk production. It was determined that along with the assessment of the economic efficiency of production based on indicators of gross production, labour productivity, cow productivity, cost of production, profitability of sales, gross income and net profit, it is advisable to carry out a comprehensive assessment of the financial state of the enterprise. The analysis of the economic efficiency of milk production in the subsidiary company \"IMK\" LLC \"Chernihiv Industrial Milk Company\" gave us the opportunity to single out directions for optimizing production costs and form vectors of development of the company's dairy direction.

The negative impact on the condition of agricultural lands due to the use of outdated agricultural technologies and non-compliance with the rules of agricultural activity was determined. It is noted that since the main elements of organic farming are a system of scientifically based soil cultivation, treatment of it as a renewable resource, introduction of permaculture technologies, mulching and other technologies, all this leads to an increase in soil fertility. The advantages of organic farming over traditional farming have been established, namely: environmental, consumer, economic, social, which are manifested mainly through the greening of production, changes in techniques and approaches to planting plants, replacement of traditional chemical fertilizers, poisons, pesticides with organic ones. The ecological advantages consist in preserving soil fertility and structure, reducing the phytopathogenic background, stopping soil degradation processes, and restoring biodiversity. Consumer benefits are mainly the improvement of quality characteristics of organically grown food products. Economic advantages are manifested in the increase in the efficiency of production of organic products, the growth of GDP and the level of employment. Social benefits include reducing the risk of various diseases. An analysis of the dynamics of the main indicators of the development of organic agriculture in Ukraine was carried out, namely: the number of operators (producers) of organic products and the amount of land under organic production. A positive trend of growth in the number of producers of organic products and the area of land on which organic products are grown was noted. Since organic farming contributes to the further strengthening of the ecological balance, its development is observed in more than 180 countries and plays an important role in achieving the goals of sustainable development. The identified advantages of organic farming form the need for the development of this field in Ukraine as well","PeriodicalId":33687,"journal":{"name":"Bioekonomika ta agrarnii biznes","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70000058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The staff that remain are forced to bear double and sometimes triple the burden of obligations, which, however, is not compensated by a corresponding increase in wages. In this aspect, it is important to establish effective mechanisms for supporting employees, designed to provide them with not only material, but also psychological help, provide friendly support in difficult situations, etc. Considering this, one of the key challenges of the new reality is the issue of effective human resource management under the conditions of martial law and active hostilities, which has actualized the need to search for theoretical and practical aspects of its overcoming.

The justification methods made it possible to single out the advantages of the information presented in non-financial reporting, in particular: it is easier to get financing; it is easier to enter foreign markets; will have more opportunities to attract customers; will be able to maintain its reputation at a high level; will have useful information for business owners; the company will get opportunities to support its reputation in the information space. The use of the generalization method made it possible to single out the qualitative characteristics of information in management reporting, to form blocks of information that can be placed in a non-financial annual report, and to outline the place and role of non-financial and management reporting as an information tool for risk management.

Analyzing the financial indicators, it has been proven that one of the priority directions in the activities of this Bank is the development of lending while maintaining the high quality of the loan portfolio. The Bank's strategic goal is to build a high-quality credit portfolio of retail and SME loans.As a result of the research, an analysis of the main analytical indicators of credit portfolio management was carried out, the structure of the credit portfolio and the structure of the credit quality of the bank's portfolio were determined during 2019–2021. The practical activities of JSC CB \"PrivatBank\" were studied and it was established that large loans granted to large enterprises mean big risks for the bank and its millions of depositors. But adhering to this balanced credit policy, the Bank still manages to increase its own credit activity, as evidenced by analytical calculations.To achieve the goal, the research used general scientific research methods: observation (systematic study of the bank, obtaining primary information in the form of financial reporting indicators for the analyzed period), comparison (comparison of the analyzed parameters, coefficients, balance sheet items with each other or with a basic indicator, normative value), abstraction (departure in the definition of categories from non-essential properties and selection of several essential characteristics), grouping method (when considering the classification of loans); various methods of statistical methods, in particular comparison - when comparing actual data for the relevant periods; observations were used to study and assess the financial condition of JSC CB \"PrivatBank\", methods of analysis and synthesis, induction and deduction.It has been analyzed and proven that the decline in business activity since the beginning of the full-scale war has led to a drop in business demand for loans. At the same time, the deterioration of macroeconomic expectations significantly reduced the risk appetite of banks. Accordingly, financial institutions have tightened lending standards for businesses. Therefore, the growth of the loan portfolio almost stopped: the amount of foreign currency loans decreased, while hryvnia loans increased several times slower than last year, and the hryvnia net corporate loan portfolio increased by 8% since the beginning of the full-scale war.Ways to solve the problems of improving and improving the quality of the bank's credit activity remain prospects for further research","PeriodicalId":33687,"journal":{"name":"Bioekonomika ta agrarnii biznes","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70000672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
