      The article reflects the results of studies on the establishment of productivity and cost-effective cultivation of corn hybrids, depending on the density of standing plants and the background of mineral nutrition. It has been proved that in order to obtain the maximum yield when growing the DKS 3730 hybrid, it is necessary to form plant density at the level of 80 thousand/ha; DKS 4764 – 70 thousand; DKS 4795 – 70-80 thousand/ha. The lowest level of cost (1.93-1.98 thousand UAH/t) was recorded in the DKS 3730 hybrid with a plant density of 80 thousand/ha and on the DKS 4795 hybrid with a density of 70 thousand/ha.         The conditional net income exceeded 40 thousand UAH/ha on the variants with hybrids DKS 3730 – with a plant density of 80 thousand UAH/ha; DKS 4764 – with a density of 70 thousand/ha; DKS 4795 – with a density of 70-80 thousand/ha. The maximum level of profitability – 143.5% was in the DKS 3730 hybrid with a plant density of 80 thousand/ha. The tendency to increase the value of gross output and, accordingly, production costs in proportion with the increase to nitrogen and phosphate fertilizers was established. The highest net profit in the experience at the level of 45.7 thousand UAH/ha was obtained on the variant with the hybrid DKS 4795 with the application of fertilizers in the dose of N90P90.

        Keywords: hybrids corn, plant stand density, fertilizers, grain yield, economic efficiency.

     The article presents the results of studies on the influence of the sowing time of various varieties of winter barley and microelement compounds used for pre-sowing seed preparation on the formation of leaf area, photosynthetic potential and the synthesis of absolutely dry plant mass. The optimal sowing dates and possible deviations of the sowing dates for each of the varieties have been established. Due to the significant lack of winter barley – low resistance to low temperatures, – considerable attention is paid in the article to its winter hardiness. Features of growth, development, formation of winter hardiness and productivity are considered taking into account the climatic conditions for the period of research.
    It is proved that the potential productivity of barley at the initial phases of development depends on a number of components, where the main ones are: leaf area and the timing of its photosynthetic activity.
    In the conditions of the south of Ukraine, the formation of the vegetative mass of barley seedlings is caused not only by the biological characteristics of the varieties, but also largely depends on the time of sowing. The largest mass of absolutely dry matter of seedlings of various varieties of barley was synthesized during the first term of sowing.
    When changing the time of sowing seeds, especially under adverse conditions, the periods of active vegetation of plants are significantly reduced, as a result of which the mass of dry substances decreases by 48.6-55%. The analysis showed that among the studied varieties of winter barley, the most efficiently limited natural resources were used in shoots of the Ninth Shaft variety, ensuring the formation of 156.4 kg / ha of dry matter until the end of the autumn vegetation.
    It is noted that the accelerated formation of leaf area, an increase in the photosynthetic potential and high productivity of photosynthesis, under adverse conditions of water and thermal conditions, are most fully provided by the Ninth Shaft variety.
    It has been shown that microelement compounds applied at the stage of pre-sowing seed preparation, accelerated the passage of the first stage of organogenesis by plants, increasing the duration of the active growing season of the ladder, as a result of which the mass of absolutely dry matter increased to 40.4 % and reached 155.7-230.4 kg/ha compared to the control.

    Keywords: barley varieties, sowing dates, trace elements, leaf area, mass of absolutely dry matter.

       The article examines the essence of the concept of “rural territory” and establishes that rural territory is considered as a social-spatial education, which combines the following components: organizational, industrial-economic, socio-economic and natural-resource. It is substantiated that the main feature of rural territories is its interrelation with the administrative-territorial system. In particular, rural areas become the object of self-government, a unit of local self-government, the main purpose of which should be the policy, aimed at satisfying the diverse needs of the peasants.
      On the basis of the research, we have found that the development of domestic rural areas in today’s conditions is characterized by significant structural, functional and related demographic, social problems, low investment and innovation activity, decline of infrastructure support, the existing communal crisis, low level of activity, solidarity and integration of the population in the management processes.Most of these problems are due to insufficient legal certainty, high level of centralization, and lack of system-synergetic management of public processes at the state level.
      It is determined that in order to allow rural areas to develop, and residents of the settlements could get the right to modern medicine and education, good roads and illuminated streets, to obtain affordable and high-quality administrative, communal and social services, decentralization of power is taking place in Ukraine.
      It is substantiated that the municipal united territorial communities are communities with a significant number of rural and urban populations, and the dominant center is the city.At the same time, it was established that domestic legislation does not specify requirements for the mandatory population of the community, but the practice has shown that the community with more than 10 or 20 thousand people will be more financially capable.
      As a result of the research of the activities of the Bashtanka and Mena city united territorial communities, it was established that for the development of their own rural areas, local self-government bodies of city UTC (united territorial communities) apply a number of measures not prohibited by law, namely: conduct public hearings and referenda, organize and conduct general meetings of citizens for place of residence objectively and in time to consider collective and individual appeals of residents to bodies and officials of municipal self-government, gives the opportunity to Invitations to prepare and submit local initiatives to the council. Also, such communities, in strategic planning of their development, see one of the strategic goals as developing rural areas through the development of the agrarian sector, ensuring adequate quality of life in rural areas, development of entrepreneurship, etc.
      Having examined the programs of socio-economic development of Bashtanka and Mena City UTC, it was stated that in strategic planning of their development in these communities there is no clear definition of the strategic goal of “development of rural territories”, both communities focus on the development of rural areas through the creation of favorable conditions for the economic development of the community and improving the quality of life of its inhabitants, based on their resources and understanding of reasonable growth.
     It is concluded that the city’s united territorial communities are a powerful incentive for the development of rural areas, have considerably higher revenues to local budgets, thereby strengthening the budget opportunities of rural areas. In particular, urban UTCs, due to the combination of urban and rural areas, extend the positive impact of cities to neighboring rural areas and make more effective incentives in these areas for attraction investors to the countryside.

     Keywords: rural territory, decentralization, united territorial communities, budget, financial decentralization, development.

    The article investigates the use of innovative investment resources as a general precondition to restore the industrial potential of the agro-industrial complex, to overcome its economic and technological lag. The purpose of the study is to identify the promising directions for updating the material and technical base of agrarian enterprises on an innovative basis.
    Theoretical researches concerning provision of agricultural enterprises with material and technical resources are generalized. The emphasis is placed on the need to establish the interdependence of objective reasons with subjective ones, which will allow developing more effective strategies for reproduction of material and technical base of agricultural producers.
    Interconnection between the transition to the industrial information society and evolutionary changes of fixed capital is proved, when agricultural producers change production technologies under the influence of information, which entails changes in the composition and structure of fixed assets, their age, qualitative, social, environmental and other characteristics .
   The group of factors, which promote attraction of investments in agro-industrial complex, is established and classified. The first group of factors is proved to determine the investment potential of the agro-industrial complex and to characterize its availability with the necessary resources; the second group determines the investment climate of the agro-industrial complex of the country or region. A large part of investments in innovation is substantiated to be of high risk, they affect the possibility of attracting investors for their implementation. The positive and negative factors of attraction of investments in innovations of agrarian sphere are characterized.
   The main tasks of the investment activity in the industry are formulated, which include not only the development of entrepreneurship in the agrarian sector, but also solving the social, economic and environmental conditions of the rural areas and their inhabitant development.
   The stages of solving tasks of investment activity in the agrarian sector are defined. According to the authors’ thought, the first step is to direct financial assets for the intensive renewal of the active part of fixed assets; and the second step is to invest in the development of resource-saving industries in the agro-industrial complex; the third step is to fulfill technical and technological modernization of the industrial base of the industry.

   Keywords: agricultural enterprise, material and technical base, resource support, innovations, investments.

    Rural territories play a key role in economic growth of both – the state itself, and the particular Ukrainian village as well. The necessity of fundamental change of the power system and its territorial basis on all the levels, and also the implementation of real steps towards the stimulation of the country development, today is considered to be an answer to the current challenges. It is the decentralization which increases opportunities and really is a powerful driver for the stimulation of the rural territories development.
   A decentralization reform gave rise to the formation of the competent local government in local communities – a power institution, which is the closest one to the citizen. Voluntary association of local communities let the newly formed local authorities obtain the appropriate power and resources.
   The literary sources analysis shows that the majority of the latest scientific works is devoted to the questions of the rural development or to the sustainable development of the rural territories. However, the decentralization, introduced during the last three years, which structurally reconstructs the rural areas and changes their territory and administrative landscape, determines the search for new approaches. And also requires the actualization of this area of research.
   The complex evaluation of the decentralization of the development and organization of socio-economic regulation of the rural territories, held in the article, shows that the last ones play the main role in the process of reforming of the local government and territorial organization of power, and are considered to be self-sufficient and capable systems.
    It was found that the positive experience of the decentralization process took place, but the newly established united territory communities have a number of unresolved issues, connected with the development of the long-term plans of the territories formation, stable providing of the state support, optimal distribution of power between the local governments and the executive authorities, distribution of functions and power between the local councils and the  district administrations and the district councils of each district, on the territories of which the communities were established.
      Key words: decentralization, general territorial community, rural territory, development, municipal cooperation, financial capacity of communities.

Basic scientific approaches to management in modern education

UDC 378.14

        It should be especially emphasized that in today’s conditions of the labor market, new models of economics and control of educational institutions are required, solving of problems of this branch development in general depends on them. That is why searching for new ways of managing and improving the organization of the educational process is gaining the special significance in modern conditions.
        In the theory of management, there are two points of view on the relation between the concepts of “control” and “management”. Some authors believe that control is only one of the functions of management, while others – other way round. We believe that the concept of “management” covers the following aspects of the control of a particular institution, such as types of managerial control, features of motivation, work with personnel, control styles. Management in education is always an orientation of executive functions to the needs of the labor market, the demand for various types of services. Control in education – is the orientation of executive functions for specific decisions of higher organizations, managers, achievement of the goal. Summarizing Western practice, we have the following definition of the term manager: it is the subject of management in an organization, a professional chief who realizes that he is a representative of a special profession, and not just an engineer, economist or teacher who is in charge of management.
        In management, the controlling cycle includes the main managerial functions: planning, organization of activities, regulation and control. Thus, controlling functions are considered as specific types of management activities that form a cyclic process of control. The accumulated experience allowed the author to conclude: the crisis of education is not related to the shortcomings laid down in the very idea of reforming education, but with errors in the management of this system both at the state level and at the level of educational institutions themselves. Scientific control is not just a conscious control. This is a control, the subject of management relies on in his influence on society, on the scientific laws of social development perception.
        In our opinion, the main problem of reforming modern education in Ukraine is determining the place in this reform for the training of managers of the new formation. It is a pity that the concept of the “New Ukrainian School” does not involve the training of the heads of educational institutions.

      Key words: control, management, pedagogical management, scientific control, functions, principles, methods of control.

       The article deals with the main factors influencing occupational injuries of agricultural enterprises. It is established that the change in their number and level of influence depends on the limited capabilities of human rights systems and the multiplicity of manifestations of its mental characteristics. For example, the multivariate behavioral reactions presented system of inadequacy of action to the emerging external conditions, which suggests the unreality of achieving absolute security. Practice shows that isolated delays such as compensations for poor working conditions, and the provision of means for collective and individual protection of workers at enterprises do not ensure the implementation of a strategy for improving working conditions and reducing injuries at agricultural enterprises. Only an integrated approach based on professional risk prevention with the development of national priorities in the development, design and manufacture of modern agricultural machinery for agriculture, bringing the current legal framework for labor safety in line with international and European labor standards is a sufficiently effective measure to prevent occupational injuries.

       Keywords: agricultural machinery, priority areas, safety, production equipment, legal framework, machines, units, mechanisms, improvement of safety, safety measures.

      An important task of producers is to provide the population of Ukraine with high-quality foodstuffs, which increases the level of consumers’ welfare, improves the health of people.
      The Law of Ukraine “About Information for Consumers regarding Foodstuffs” establishes the legal and organizational principles for giving consumers information about foodstuffs in order to ensure a high level of the citizens’ health protection and to meet their social and economic interests.
      The main innovations of the new law are: obligatory information about foodstuffs should not be concealed or distorted by other text or graphic information; duties of food market operators responsible for informing should be regulated; prohibition of the use of data, particularly in advertising, which can be misleading (concerning qualities and characteristics of products and effect of their consumption, as well as attributing them medical qualities); informing about the content of additives and substances that cause allergies or intolerances; regulation of rules of giving information about foodstuffs that are sold remotely-delivered; informing about whether the food was unfreezed. The name should contain the word “defreezed”; deviation from the obligatory indication of the nutritional value of raw products, or products which don’t need such data for acquiring; the height of small stationary elements, by means of which it is marked, must be equal or exceed 1.2 mm; when using packaging or containers the surface area of ​​which is less than 80 cm2, the height of the small elements should be more than 0.9 mm.
      The implementation of the law makes it possible to provide consumers with information about food products or ingredients, their composition, nutritional value, method of consumption, as well as systematizes the requirements for food information in one law, harmonized with the legislation of the European Union.

      Keywords: draft law, labelling, foodstuffs, product safety.

Advantages of hybrid mobile applications and progressive web apps for entrepreneurs

        The article deals with the problems of using mobile applications by business entities. The possibilities of obtaining additional benefits from the use of advanced web applications and hybrid mobile applications were analyzed. The main advantages and disadvantages of hybrid applications are determined and compared with native applications.
       Using mobile applications to interact with customers makes the experience of using the service much more enjoyable due to deep personalization, high availability and smoothness of work. However, the native development of applications for different platforms is not always appropriate in view of the ratio of results obtained and spent resources.
        The concepts of hybrid mobile applications and advanced web applications have many common features. We believe that within the next 5 years, PWA’s rapid growth will take place, as technology is much more attractive than traditional applications directly installed on the device.
        Today, PWA has such disadvantages as limited access to native mobile APIs and low support. Given the foregoing, we believe that the development of hybrid mobile applications gives more benefits to entrepreneurs than the development of PWA. It should be noted that the Ionic Framework, in addition to the Android and iOS apps, can also collect progressive web applications, which makes the use of this tool most profitable under conditions of low resource availability.
        A very promising framework is the React Native framework, which allows you to develop native applications without losing the possibility of cross-platform development. The use of this approach is much more rational than the technological point of view, but the entry threshold for React Native technology is much higher than in other frameworks, which in turn significantly increases the cost of development.
      To sum up, it should be noted that the development of hybrid mobile applications has both advantages and disadvantages, so when choosing an approach to developing mobile software, the priorities for the application should be determined. For example, if an application needs to process large amounts of data, perform complex computing operations and provide maximum performance, then the hybrid applications and PWA should be discarded in favor of native software.

     Keywords: mobile application, hybrid mobile application, progressive web application, smartphone, native, framework, cross-platform.
