Description
We took 20 samples of centralized water for bacteriological studies at two farms of the collective farm “Limann” and the collective farm “50 years of the name of the October Revolution” of the Neklinovsky District of the Russian Federation and sent to the Rostov Regional Veterinary Laboratory. Thus, according to the results of laboratory studies of water, it was found that in the first farm in 7 samples out of 10 under No. 1, 2, 4, 5, 8, 9, 10, common coliform bacteria were found (the number of bacteria in 100 ml according to MUK 4.2. 1018-01), as well as thermo-tolerant coliform bacteria (the number of bacteria per 100 ml according to MUK 4.2.1018-01), in the second farm in 5 samples out of 10 under No. 3, 4, 5, 7, 8 common coliform bacteria (number of bacteria per 100 ml according to MUK 4.2.1018-01), as well as thermo-tolerant coliform bacteria (number of bacteria per 100 ml according to MUK 4.2.1018-01). According to the results of studies using the rapid test "Biocontrol" revealed that in the first farm in 2 samples out of 10 under No. 4.9 per 1 ml of bacteria 105, which indicates water pollution, and in 5 out of 10 samples No. 1, 2, 5, 8, 10 per 1 ml of bacteria 107, which indicates a strong pollution of water and is the basis for the prohibition of watering animals. In the second household, in 3 samples out of 10 under No. 4, 5, 8 per 1 ml of bacteria 105, which indicates water pollution, and in 2 out of 10 samples No. 3, 7 per 1 ml of bacteria 107, which indicates severe water pollution which is not recommended for animals. Thus, the studied water samples by the bacteriological method coincide with the “Biocontrol” rapid tests, which makes it possible to practically use it in farms

08.00.13 Mathematical and instrumental methods of Economics
DescriptionIn the article, we develop the methodology of strategic planning and management of the holding on the theoretical basis of automated system-cognitive analysis (ASC-analysis). This methodology provides scientific research of any holding by creating and researching its model. The methodology includes both the synthesis, adaptation and verification of system-cognitive models of the holding, and the use of these models for strategic planning and decision support for managing the holding, as a complex, multiparametric, nonlinear system. The relevance of the research is due to the special role of holdings and other corporate integrated structures both in Russia as a whole and, in particular, in the Krasnodar region. Despite obvious system advantages, holdings face a wide range of problems related to management efficiency, ensuring their sustainable functioning, etc. The proposed methodology offers ways to solve these problems and can be successfully applied in holdings and other corporate integrated structures of various regions, volumes and areas of activity, which determines the relevance of the research topic. The level of significance and scientific novelty of the Research consists in the development of conceptual and theoretical and methodological provisions aimed at managing the development of holdings. The expected results and their significance are that the methodology developed as a result of the Research can be applied by holding companies and other corporate integrated structures and will significantly improve the quality of their management

06.01.05 Selection and seed production of agricultural plants (agricultural sciences)
DescriptionThe article discusses the method of selection using markers in the selection of parent pairs for hybridization, in the selection process and in the subsequent evaluation of parent lines, used in linear and backcross selection of tomatoes. The work was performed on tomato hybrids that combine resistance genes to tomato mosaic virus (ToMV) or tobacco mosaic virus (TMV) in their genome. The research used seeds of foreign F1 tomato hybrids recommended by the manufacturer as resistant to the tobacco mosaic virus. Most of the tomato hybrids were Dutch selection, such leading firms as De Ruiter Seeds, Enza Zaden, Rijk Zwaan. The aim of the work was to test a system of hybridization probes designed to identify a gene for resistance to the tobacco mosaic virus. The study of the genotype of tomato plants was carried out in the laboratory of molecular diagnostics of plants , equipped with modern devices for PCR analysis on the basis of NIIOZG (Krymsk). Plant material was collected in different phases of plant vegetation. pre-numbered 1.5 ml test tubes (SSI-1200-00), plastic tablets, tweezers, and distilled water were used to collect plant samples. The collected samples were stored in a refrigerator until the plant DNA was isolated. During the study, collectible tomato samples were studied, including 8 F1 hybrids and 2 lines used as controls. According to the results of genetic analysis using the marker of the TMV resistance gene, it was found that all hybrids and one control line # 175/14 have a resistance gene in their genotype, and the analysis also showed the state of the gene – homozygous or heterozygous. The results of artificial infection confirmed the results obtained by PCR analysis. At the same time, using genetic research, it is possible to determine the exact state of the gene in the plant, which cannot be determined by methods of artificial infection, since no visual differences were found between plants with a heterozygous and homozygous state of the gene. The created marker and PCR analysis method can be recommended for wide application in the selection process of tomato culture. As a result of research, it was found that modern tomato hybrids have a gene for resistance to tobacco mosaic virus (TMV) in their genotype. This was determined by genetic analysis and confirmed by a test using artificial infection

CORRECTION OF DYSBIOTIC DISORDERS IN BEES BY USING PROBIOTIC MEDICATIONS
DescriptionThis article provides an overview of the need of the use of probiotic supplements and medications in the diets of insects, in particular bees and their families. We present a list of both Russian and foreign probiotics and their complexes, which are used in beekeeping for the treatment and prevention of various diseases, are shown. Their effectiveness is shown not only for the prevention and treatment of microbial disorders in the gastrointestinal tract of bees due to the manifestation of antagonistic properties in relation to opportunistic and pathogenic microflora, but also the possibility of their use as tools that can increase the immune status, the safety of bee families, and life expectancy. The article shows data on the positive effect of probiotics on the physiological and biochemical parameters of honeybees, activation of metabolic processes in the formation of a fat body, growth of strength and weight of larvae, development of pharyngeal glands, etc.

THE RATIONALE FOR THE USE OF COMBINED UNITS IN THE CULTIVATION OF WINTER WHEAT
06.01.01 General agriculture, crop production (agricultural sciences)
DescriptionIssues related to the use of combined aggregates in soil preparation are relevant and of scientific and practical interest. The relevance is increased when it comes to the cultivation of the main crop – winter wheat. In this regard, the presented results on the efficiency of using combined aggregates in preparing soil for winter crops are important primarily from a practical point of view. Experimental studies were conducted in the conditions of long-term stationary experience in the Federal state budgetary institution «Agrarian Science Center «Donskoy», Zernograd, Rostov region. The article considers the efficiency of using the combined unit APK-4, developed in "SKNIIMESH" now Federal state research institution of the «Agrarian Science Center «Donskoy» in the cultivation of winter wheat. The structural and technological scheme of a combined unit, the technological process of which consists of several technological operations performed at the same time, is justified. Disk working bodies crush plant residues and destroy weeds. This creates a network of cracks in the underlying soil horizons. Next, there are flat-cutting working bodies that loosen the soil to a set depth. The root system of weeds is pruned, the remaining loosened soil layer is loosened to the required depth, the formation of a smooth bottom of the "furrow", and the separation of erosive soil particles to the bottom of the furrow. Next, the roller starts working – a lump-crushing sealer, which provides crushing of soil lumps on the surface and sub-compaction of the treated layer. The last in the technological chain is a mulching roller, which provides the formation of a compacted seedbed for seeds with simultaneous mulching of the compacted soil layer. The use of the combined unit in the technology of winter wheat cultivation allowed to reduce the number of technological operations by 1,5-2,5 times, increase the productivity of winter wheat by 11-13% and the cost of production by 10,4-18,3 %

GROWTH AND DEVELOPMENT OF SUGAR CORN DEPENDING ON NITROGEN FERTILIZERS
06.01.01 General agriculture, crop production (agricultural sciences)
DescriptionThe article provides an overview of the results of a study of the effect of nitrogen fertilizers (sowing and top dressing) on the growth and development of sugar corn plants. The object of research was the mid-early hybrid of corn called Krasnodar Sugar 280 NE (FAO 280). In the experiment, 2 factors were studied: factor Ā - sowing nitrogen fertilizer (b / b (k), 15 and 30 kg.d.v / ha), factor B - root nitrogen top dressing (b / b (k), 15 and 30 kg.dv./ha). The total area of the plot is 20 m2, the accounting area is 10 m2. The number of rows in the plot is only 4, including accounting - 2. The plots are systematically placed. In the fall, the main fertilizer was applied in the background at a dose of N30P60K60, under plowing. Repeating four times. The predecessor is winter wheat. The counts and observations in the experiment were carried out according to generally accepted methods. Studies have established that the phases of “seedlings” and “5-6 leaves” did not depend on nitrogen fertilizers. The “panicle panning” phase in the variants with the introduction of nitrogen occurred 2 days later, and the phase "milk ripeness on the cob" - for 1 day. The height of the plants of the control variant was 202 cm. With an increase in the dose of nitrogen, the height of the plants of sweet corn increased. The maximum (12 cm higher) plant height was on the option using N30 for sowing and root dressing

05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
DescriptionThe article describes reasons for uneven distribution of seeds by pneumatic grain drills. For the theoretical justification of the operation modes of the pneumatic seeder, we have calculated the coefficients of the weight concentration of seeds in the air stream for different seeding rates and movement speeds. We have also calculated feed rate of seeds and planting performance of the machine for working width of 8.4 m. We have derived an equation of constancy of consumption of seeds, and the equation determining total pressure loss in the pneumatic conduit, emerging from the sum of the losses in the receiver, losses on the dispersal of the material after the receiver, and losses on the stopped movement of pneumatic mixtures

05.13.18 Mathematical modeling, numerical methods and software complexes
DescriptionThis work continues the series of works written by the author on the application of modern scientific methods in the study of human consciousness. In 1979-1981, two monographs were written devoted to higher forms of consciousness, the prospects of man, technology and society. One of these monographs was two-volume and was called "Theoretical Foundations of the Synthesis of Quasi-Biological Robots." In these monographs the author proposed: 1) criterial periodic classification of 49 forms of consciousness, including higher forms of consciousness (HFC); 2) based on this classification, there were psychological, microsocial and technological methods of transition between various forms of consciousness, including methods of transition from the usual form of consciousness to the HFC; 3) information-functional theory of the development of technology (including the rule of improving the quality of the basis); 4) information theory of value; 5) 11 functional schemes of technical systems of future forms of society, including remote telekinetic (mental) control systems; 6) the concept of development of society in groups of socio-economic formations; 7) the concept of determining the form of human consciousness by the functional level of the technological environment; 8) mathematical and numerical modeling of the dynamics of the probability density of states of human consciousness in evolution using the theory of Markov’s random processes. In this study, we carry out a complete automated system-cognitive analysis (ASC- analysis) of the periodic criteria classification of forms of consciousness proposed by the author in 1978. To this end, the following tasks are solved in the work: cognitive structuring and formalization of the subject area; synthesis and verification of statistical and system-cognitive models (multi-parameter typification of forms of consciousness); systemic identification of forms of consciousness; their typological analysis; investigations of a simulated domain by examining its model. We have also given a detailed numerical example of solving all these problems
