AGRO-ECONOMICAL ASPECTS OF GROWTH STIMULANTS AND MICROFERTILIZERS APPLICATION ON BUCKWHEAT
Description
The article highlights the food value of buckwheat. It is said that the achievement of its biological potential under prevailing conditions of cultivation is impossible without the introduction of modern scientific and technical progress. The authors describe variants of integrated application of growth stimulants and microfertilizers in buckwheat production technology. Recommended technologies have been tested in conditions of the Central Chernozem region. It is revealed that the best variant of pre-sowing seed treatment is the combination of Epin-extra and Rexolin ABS. Conbination of Epin-extra and Speedfol B is the best variant of treatment of vegetating plants, providing the maximum yield increase in comparison with control variant (without treatments). Economic efficiency of all proposed technologies was studied. The system of indicators was chosen, which evaluate the efficiency of 36 variants of seed and plant treatment with growth stimulants and microfertilizers. A comparative analysis of variants demonstrated that the application of Speedfol B in combination with EPIN-extra and Rexolin ABS is most cost-effective and profitable. It is noted that the final choice of combination of growth stimulants and microfertilizers will depend on the specific conditions of cultivation. Recommendations are given

RESEARCH OF PROVIDING INFRASTRUCTURE OF MINERAL FERTILIZERS TO AGRICULTURAL CONSUMERS
Description
Currently, for producers of mineral fertilizers one of the main tasks is the process of creating a supply chain of mineral fertilizers delivery to agricultural consumers, running on a «Just-in-time» way. The effective operation of such a supply chain has to be influenced by many factors, including: the technology of agricultural production, seasonality of agricultural work, the structure of the distribution channel of mineral fertilizers, the geographical features of consumers, the availability of appropriate infrastructure, etc. Critical elements of the infrastructure are warehouses and equipment for storage of mineral fertilizers, as well as the road network. For example, farms in the Rostov region were analyzed for the infrastructure necessary for the successful supply of mineral fertilizer agricultural consumers. It was found that the capacity of warehouses and facilities for the storage of mineral fertilizers and distribution of cultivated areas between agricultural enterprises of different size are diametrically opposed. The process of delivery of mineral fertilizers need to be developed taking into account the shortage or complete lack of storage capacity for their storage, especially for small enterprises. The existing road network, with paved allows us to deliver of mineral fertilizers virtually all consumers by road transport. This dictates the feasibility of delivery of mineral fertilizers to consumers by road transport in soft containers (Big Bags), allowing the storage in the open air

THE DEVELOPMENT AND REGULATION OF SMALL FORM PRODUCTION IN RETROSPECTIVE
Description
Theoretical, transformational and practical provisions for the development and regulation of small businesses and farms in the country's economy and agriculture are being cleared up. In the process of studying the problem we used logical reasoning, methods of comparing, and monographic, economic and statistical methods also. It is shown that small farming forms (SFF) in agriculture are essential for progressive development of agriculture, which is now recognized as a growth point of import substitution in all national economy. Given the author's interpretation of the category definition "small farming form" in agriculture differs from other definitions, in a more complete evaluation and statistics, provisions regarding private cottages and households as the SFF, their locality of functioning, independence in taking risks, increased adaptation, economic and legal binding, spectrum of production. The article shows the history of definitions of small business and small farming forms, stages of small business development, the scope of its practice abroad and in our country. It is said that a leading role in the formation of small farms belonged to households, which are still playing a leading role in production of agricultural products for their own consumption (without selling on the market). It is noted that at the present stage of industrial transformation of small businesses and small farms they often have a low mechanization level, high cost structure of manual labor. They have problems in adapting to the sector of services, in embedding into a complex system of relationships with medium and large business on the basis of technological specialization and also promoting innovation. It is emphasized that today the growing role of small businesses, small farms makes it more pragmatic to assess the prospects of development of this sector in our country

Description
Efficient dairy cattle breeding are largely dependent from technology content and service animals. Most farms use a tethered way content. With this method of milking, the technology requires the introduction of new techniques to increase productivity on the farm and cost reduction of dairy products. The most rational is improving the design of existing milking machines. Regarded device for automatic removal of hanging part of a milking machine, its structure and working principle. The main unit of the device is a pneumatic motor that operates from the vacuum system of the milking plant. In the housing mounted on the shaft of the pneumatic motor rotor with curved vanes, there are magnetic elements. These elements should have the necessary geometrical and force parameters to ensure the normal operation of the device for automatic removal of hanging part of milking machine. The article describes a laboratory research and an analysis of the magnetic elements. In laboratory studies, we have revealed a dependence of the traction capacity of pneumatic motor from linear and power parameters of the magnetic elements, as well as established necessary geometric parameters and the magnetic field strength of the elements for normal operation

THE ORETICAL ASPECTS OF INNOVATION IN POULTRY
Description
The article presents an analysis of the theoretical and conceptual foundations of innovation and innovation activities. The study revealed the following classification features of innovations: scope, object, cause of beginnings, stages of STA, which resulted in the innovation, the degree of intensity, the depth of changes, novelty, the pace of innovation realization, the scale of innovation, a place in the enterprise, productivity, innovation effectiveness, nature of the need. The final result of innovation is not only to get economic but also scientific and technological, social, ecological and other effects. The innovation process in poultry is turned directly to the introduction of new ideas on the stages of production. Poultry farming is a dynamic, growing sector of the domestic agricultural complex, the most precocious branch of livestock, characterized by high production efficiency. The cost-effectiveness of producers’ innovation is reflected by net discount profit, profitability index, the period of payback discounted costs and internal rate of return of the project. It was found that one of the most pressing issues arising at the moment is the presence of international competition. It is necessary to solve a number of problems related to the improvement of product quality, effectiveness increase of applied technologies, favorable veterinary conditions on poultry farms. In the period of introduction of innovation technologies in the poultry it is necessary to prepare promptly the personnel which will be working with the new equipment and new technologies

Description
For explaining the regulatory mechanisms of biological the methods of classical biology, chemistry and physics are clearly inadequate, since the structure and function of these mechanisms are determined by the motion of the electron clouds in conjugated molecules. This "movement" can lead eventually to a complex organization called life only if they are subject to certain static laws and, therefore, may eventually be known in all the complexity of their relationships. Biological objects, resulting in the evolution of the environment, are like a part of that environment. Information stored in the seed, based in its deployment on energy and material resources of the environment. Moreover, in the process of development body derives more information from the environment. Nature has the extreme complexity and diversity. Examples include a huge variety of organisms, the complexity of atomic processes, the structure of the solar system and the stellar galaxies. There are four types of different interactions with the help of which we describe all physical phenomena. Today, it seems to us that all the various manifestations of the nature of elementary particles are reduced to the action between them of these four kinds of forces. The most famous of these are the gravitational Zion and electromagnetic forces, which are directly manifested in the world around us. Gravity allows us to stay on the Earth and allows planets to stay in their orbits. Electromagnetic interactions of electrons inside atoms and molecules cause all known chemical and physical properties of ordinary solids, liquids and gases and, in addition, are the basis of all of the processes occurring in living organisms. Research in the field of magneto proved that the biological systems are selectively susceptible to the action of electromagnetic fields as a function of their intensity, exposure time and frequency

MODERN METHODS OF EVALUATING THE PRODUCTIVITY OF THE RESEARCH ACTIVITY
22.00.00 Sociological sciences
Description
The purpose of the research is development of the new methods of diagnostic the research activities productivity. It is known, that for the evaluation the productivity of a scientist we usually use a well-known index of Hirsch, the introduction of which in 2005 was a significant step forward compared with application of this index as the ratio of the number of references to works of scientist and publications themselves. At the same time even h-index as an indicator is not flawless, the main flaw is weak differential ability: a number of links to the most cited publications of the scientific worker does not matter after reaching a certain threshold. It is necessary to develop a method of estimating the productivity of scientific worker, which preserves dignities of h-index and removes its shortcomings. This will allow evaluating the productivity of research activities more objectively. Methodological bases of the research: a systematic approach (considering the science as a social institution in close connection with the society as a whole), a metasystem approach (considering the results of the scientific activities as a metasystem, i.e. the system with relatively independent components), probabilistic and statistical approach (considering the research activities as the random process), a synergistic approach (considering science like a self-organized system) qualimetric approach (considering the productivity of scientific activity as latent variables that reflect a variety of criteria)

DEVELOPING LOW TEMPERATURE SOURCE LOCAL HEATING FOR PIGLETS
06.00.00 Agricultural sciences
Description
During the research, we have developed a low-temperature zonal heating panels with an infrared emitter to create a local microclimate for piglets in the suckling period. This heater is lightweight and durable frame in the form of an inverted box size 400 mm x 1800 mm, attached to the wall of the building swivel. Top frame mounted thermostat is connected to a temperature sensor mounted directly on a metal plate with a thickness of 1 mm, painted in black color. In the upper part of the inner carcass layer is a light insulating material, which is located directly under the low-temperature heat source is electric. Study of the optimal size of the heating panel revealed that in view of the limitations associated with the area of the machine and biological characteristics of the optimum size of the sow for 11 piglets are: width – 400 mm; length – 1500 mm (at ventral position) and 1800 mm (lateral position). Comparison of different heating sources for piglets revealed that the use of infrared lamps enables newborn piglets seating area by 55.6%, while in 28 days – by 88.9%. Infrared lamps can not completely meet the recommended specifications as to ensure a more intense heat lamp to be lowered towards the floor surface, which leads to a reduction in the useful area heated. Using as a source of local heating mats and low-temperature panels satisfies pigs in the area of the den in the early suckling period at 138.9 and 200.0%, to weaning, respectively – by 48.5 and 65.5%. Thus, we have developed a low-temperature heating panels contributed to a more uniform distribution of heat in a recreation area of suckling piglets and to provide a comfortable environment at temperatures of 2-3 C lower in comparison with other methods of heating
