Authors: Frolova O Y , Fomina L V , Shmeleva Zh N 
Published: September 2020

Abstract
When solving problems of the socio-economic development, coordination of interaction between various organizational systems becomes relevant. The quality of the socio-economic process in the system is determined by the presence of elements in it that ensure the implementation of interests at the level of general, private, individual, both in the present and in the future, where the driving force is the needs, and the basis for satisfying the interest is material production. Methodological aspects of the agricultural sector impact on the socio-economic process in the region are related to the provision of foodstuffs to the population. The nature of interaction between the agrarian sector and the socio-economic system represents a multi-level structure of interaction between the production, social, and environmental subsystems of the public economy. Hence, the importance of coordinating development between different systems in order to achieve a focused useful result becomes indispensable. The significance of the agrarian sector as a local system in the socio-economic process is clarified in the article based on the positioning of functional relationships, features of functioning, elements of the agrarian sector (territorial community, natural environment, material and technical resources included in the agro-industrial complex). The levels of spatial localization coverage including the mechanism of interaction, regulatory elements, indicative indicators that reflect the implementation of economic interest are revealed. The organization of the socio-economic process according to the phases of solving a practical problem allows to coordinate the interaction of local governments and business structures.

Published: September 2020

Abstract
In this article, the authors associate the actual purchase of food for the internal affairs bodies with a rather complicated situation that affects the activities of agricultural producers in the context of self-isolation of citizens and the introduction of “food” sanctions and retaliatory sanctions on the part of Russia. The scientific analysis of the basic legal categories “state contract” and “state order” is carried out. Among scholars in the modern scientific legal and economic doctrine there is no consensus on the content of the above terms. The authors’ interpretation of the concept of “state order” is given as a proposal for discussion of the scientific community. The study focuses on the issue of concluding and executing government contracts for the purchase of food by a separate federal state institution of the system of internal affairs bodies.
The extreme factors influence on the grain quality technological indicators of spring wheat of Siberian selection
Authors: Kozulina N S , Fomina L V , Shmeleva Zh N 
Published: September 2020

Abstract
Cultivation of agricultural crops and obtaining stable yields with high technological qualities of grain are often limited by extreme environmental conditions during the plant growing season. Mongolian agriculture is characterized by a high level of dependence on natural conditions, resources, and changes in ecological systems. Sharp temperature fluctuations, high contrast and insufficient precipitation during the growing season create extreme factors for cultivating crops in Mongolia. Spring wheat varieties of Siberian selection are resistant to adverse environmental factors and have good baking qualities. In the framework of the contract between the Krasnoyarsk state agrarian university and HHK “IngetTolgoy” company (Mongolia), the research on studying extreme factors influence on the technological parameters of spring wheat grain of Siberian selection on the land of HHK “IngetTolgoy” company was conducted. The objects of research were wheat varieties of Siberian selection Novosibirskaya – 15, Novosibirskaya – 31, Kantegirskaya – 89 and varieties Selenge and Tsagaan dagliy, cultivated in HHK “IngetTolgoy” company. Recording was performed using generally accepted methods and existing State Standards. Statistical processing of the obtained data was performed by the method of dispersion and correlation analysis. The obtained results allow to conclude that despite the influence of extreme factors on wheat during the entire growing season, the highest biological yield and the best technological qualities of grain were formed by the spring wheat variety of Siberian selection Novosibirskaya – 31.

Authors: Alexandrova E N , Tarasov K L 
Published: September 2020

Abstract
Using freshwater resources of the mixed forest zone in Russia when growing larvae of crayfish belonging to the subfamily Astacinae in order to obtain a planting material (PMC) is considered in the framework of the functioning of the ecosystem that is formed in cages placed in surface layers of bodies of water. Aquatic vegetation, with which, according to the technical regulations, net cages are filled, creating shelters for larvae, is an autotrophic producer, whose consumers are organisms of benthic fauna chopping and detritizing it. Crayfish larvae in this ecosystem are heterotrophic macroconsumers that consume benthic invertebrates, vegetation, and detritus. The saprobic component of the ecosystem - microorganisms-destructors of dead organic matter are bacteria and fungi, some species of which cause mycoses of crayfish larvae. The studies conducted are devoted to determine the parameters of the functioning of the ecosystem formed in cages, providing the formation of fodder and other resources necessary for the cultivation of PMC.

Authors: Fomina N V 
Published: September 2020

Abstract
Greening the urban environment is a necessary element for improving the quality of life of the population, which requires the use of significant amounts of seedlings of flower-ornamental plants. Soil condition in greenhouse complexes does not always meet the requirements, which causes low yield and quality of grown plants. Phytotesting and assessment of ecological quality of soil in greenhouse complex were carried out through research of oxidative enzymes activity. The control of the level of toxicity and chemical contamination of soil is necessary for the development of measures to reduce and prevent changes in the soil and biotic environment. The comprehensive study of soil has revealed factors affecting its quality and suitability for growing flower crops. Dynamic changes in biological indices are recorded during phytotest of soil, as well as during control of level of enzymatic activity of oxidative enzymes. An average and low level of phytotoxicity of the studied soil is established, as well as inhibition of activity of enzymes: catalase, ascorbatoxidase, peroxidase. The soil survey in the greenhouse complex showed that for rapid diagnosis of its condition it is possible to use both phytotest of samples, to carry out analysis of the level of activity of oxidative enzymes.

Published: September 2020

Abstract
The mines of the Karaganda basin develop coal seams that are very gas-rich in methane and liable to sudden emissions of coal and gas. The mining of one ton of coal is accompanied by the methane emission from 30 to 45 m3 of into the mine workings, therefore, special attention is paid to the issues of reducing the methane content to safe values in the mining areas and its utilization. The gas content of mine working areas ranges from 30 to 100 m3/min or more. The increase in air supply to the site is limited by the air speed limit and the rational, from an economic point of view, cross-section areas of the mine workings.
Human capital as a fundamental determinant of rural development
Authors: Yakimova L A , Streltsova AV 
Published: September 2020

Abstract
The Krasnoyarsk territory is a vast area. According to the Federal State Service of the Statistic the territory population density is 1.2 people per 1 square km. Thus it makes some special demands on the quality of human capital, and it is human capital which makes it possible to develop both the rural territory and the entire economy as a whole. The problem is that human capital has suffered a lack of attention for many years. Among the ways to overcome this situation we see a number of necessary measures aimed at increasing wages for agricultural workers, improving the demographic situation, diversifying the areas of employment, improving labor conditions, and improving the quality of life. In this study, we used a sociological research method by applying a questionnaire we had compiled for the survey of rural residents. Here the author defines the term “human capital of the rural population” in her own opinion and lines up a system of indicators characterizing the basic components of the human capital of the rural population, such as health capital, education capital, labor capital, cultural and behavioral capital, as well as intellectual one. To overcome the negative situation taking place in rural areas of the Krasnoyarsk territory, it is necessary to assess human capital on the previously mentioned 5 basic components, and on base of the results to propose a socially attractive model for rural development, which in its turn will attract additional human capital. The proposed measures make it possible to increase employment in rural areas by creating agricultural cooperatives, small businesses and farms, and expand the ways of use of maternity benefit in the development of rural households and small businesses, to reduce the income tax rate for individual entrepreneurs who are registered in rural areas, as well as to increase the standards for the total area for housing construction for young families, and to apply digital forms of cultural and information services to the rural population.

Improving the accuracy of gamma radiation measurements in radiation monitoring
Authors: Moiseev D V , Lukina L I 
Published: September 2020

Abstract
The article suggests the use of unmanned vehicles for monitoring the radiation situation. The paper analyzes data on the radiation situation at nuclear power plants and identifies the main factors of external radiation exposure. It is shown that the existing means of measuring gamma radiation in real conditions have to be used in an extended energy range. To improve the measurement accuracy while simultaneously expanding the energy range of gamma radiation levels, a method is proposed for automatically compensating for additional error due to the energy dependence of the sensitivity over the entire measurement range in real time by introducing pre-calculated correction coefficients. Simulation of the proposed circuit design is performed.
Analysis of accumulated precipitation based on information from weather stations
Authors: Yakubailik O E , Yakubailik T V 
Published: September 2020

Abstract
Knowledge about the spatial-temporal distribution of precipitation is important for a multitude of scientific and operational applications, and in agricultural monitoring particularly. Due to the irregularity of the network of meteorological stations and their small number in Central Siberia, a problem arises of filling in the missing data. Different ways are possible to solve this problem. This article addresses the problem of comparing data on the amount of accumulated precipitation received from ground-based weather stations and processed in various ways to reconstruct the spatial picture. Data analysis show that of all options considered, the use of a unified NOAA CPC dataset seems more appropriate in further agro-climatic studies. Only the satellite data can provide more complete and more accurate information.

Published: September 2020

Abstract
To create maps of the available forms of nutrients in arable land for implementation of systems of mineral fertilizers differential application, various approaches of interpolation by the ordinary kriging method were used. Maps of the availability were built according to the agrochemical analysis of mixed samples compiled from elementary plots of 5 ha. In the first case, the result of the agrochemical analysis was tied to the centroids of the elementary plots, and the interpolation was carried out using point ordinary kriging. In the second case, the indicator value was attached to blocks corresponding to the area of elementary sites. In this case, the interpolated cards were obtained using block kriging. It was shown that the application of various approaches to interpolation gives similar maps of spatial distribution. At the same time, maps obtained by ordinary point kriging are characterized by a more accurate forecast compared to maps obtained using block kriging. Therefore, the construction of interpolated maps of the availability of arable lands with nutrients based on the results of agrochemical analysis of mixed samples with data binding to the centroids of the sampling cells and compiling the combined samples is more preferable.

Published: September 2020

Abstract
In the article, the task of expanding the range of work in speed and moment of traction electric drive of an agricultural tractor is considered. We propose to achieve this goal through the use of a two-stage gearbox based on a three-row planetary gear. It is proposed to shift gear ratio by eliminating one row of the gearbox from the process of converting mechanical energy. Evaluation of the effect of the proposed solution was tested on a refined mathematical model, in which the electric drive is presented as a complex “frequency converter with vector control - motor - working body. The obtained simulation results allow us to argue that with the correct operation of the system in long-term operation, energy savings of up to 12% can be achieved (for various types of soil and operating modes: arable land, driving), and for transient processes - 7-8%.

Abstract
The article presents data from the results of a study to determine the effectiveness of using unconventional feed additives for horse productivity in Yakutia. To conduct scientific experiments, 3 groups of horses of the indigenous Yakut breed were formed, 12 animals each. In order to enrich animal diets by macro and microelements, as well as to increase horse productivity in winter, the effect of zeolite-sapropelic feed additives on milk production and physiological state of animals was studied. In the process of conducting research, the following methods were used: biochemical, physiological, biometric and economic research methods. As a result of the research, it was found that the use of feed additives in feeding horses contributed to an increase in the milk yield of the experimental groups of mares 10.42% and 14.89%. At the same time, annual milk yield increased by 10.43% and 14.98%. It was found that the feed additive contributed to the improvement of the qualitative composition of milk, so for fat by 0.15% and 0.16% and protein by 0.19% and 0.32%. A study of the physiological status of animals found that the feed additives affected the biochemical composition of blood. An increase of albumin by 5.95% and 9.52%, globulin - by 1.37% and 3.42%, hemoglobin - by 1.74% and 3.20% was found in animals consuming feed additives. Analysis of the economic efficiency of the use of zeolite-sapropel feed additives in feeding mares has shown that in the experimental groups consuming feed additives, the profitability was 27.34% and 32.33%. Studies have proved the perspectivityof the use of organic mineral feed additives in feeding horses in the conditions of Yakutia.
