Morkovkin D.E. - Analysis of foreign experience of government support for the agricultural sector and the potential of using it in Russia in the context of import substitution
pp. 9-19


Abstract: The author analyzes the global experience of government support for the agricultural sector and assesses the potential of using it in the Russian Federation in the current economic situation and the need for the import substitution strategy. The research subject is the public policy in the agricultural sector of the developed countries. The research object is the international practice of implementation of programmes and the measures of government support for the agricultural sector. Special attention is given to the most effective instruments and mechanisms of government support for the agricultural sector in different countries. The author uses the range of scientific research methods: theoretical cognition, the statistical method, the method of monographic research, comparative analysis and the graphical method. The author analyzes the agricultural sector development programmes of developed countries, defines the results of agrarian policy achieved by the majority of economically developed countries while implementing the programmes of government support for the agricultural sector. The author reveals the unidirectional flow of the content of the mechanism of the agrarian policy implementation in the countries under consideration and defines the key directions in the government support for agricultural producers: subsidies for producers, budgetary financing of common services, transfers to consumers. The author emphasizes the necessity to improve the system of government support for the Russian agricultural sector producers for the purpose of ensuring national interests, food security, raising competitive performance and adaptation of government support for Russia’s agricultural sector to international requirements and standards. The author systematizes external threats and outlines the ways of overcoming the resource restrictions of the agricultural sector development. Based on the results of the research, the author formulates the aims of the agricultural sector strategic management in the context of import substitution.
Syromyatnikov Y.N. - Justification of the shape of a plowshare with steering disks of a cultivating separating ripper pp. 18-29


Abstract: The research object is the process of functioning of the excavating parts of a cultivating separating ripper, which transforms the structure and the density of a soil layer in accordance with the requirements of agronomical science for the cultivated crop. This result is achieved using the coordinated interaction of passive and active excavating parts. The machine also combs out the weed. The author considers the plowshare with steering disks, which spends less energy when moving through soil and directs soil to the separator. Theoretical researches are based on mechanical and mathematical modeling of interaction of the moving parts with soil. Experimental researches are based on the sectoral methods using strain-gage instruments and the methods of multifactor experiments planning. In the result, the process of soil cultivation using disk cultivating parts has been improved, the theory of justification of the parameters of active-passive cultivating parts for the separation and pulverization of soil and been developed; the mathematic model of interaction of cultivating parts with soil with account of energy intensity rates of technological processes has been composed. The use of methods of direct variational calculation for the justification of shapes of cultivating parts of a cultivating separating ripper helps reduce energy consumption by 10-30%. 
Sklyarenko S., Boltaevskii A.A., Pryadko I.P., Sharov V.I. - History and present of the problematics of food security pp. 27-39


Abstract: The subject of this research is the economic relations in the agroindustrial sector, the restriction in the development of which introduces the factor of food security formulated at the state level. The object of this study is the agribusiness. The authors thoroughly examine such aspects of the topic as the history and present status of the theory and practice with regards to the problematics of food security. Particular attention is paid to the analysis of the new document "Strategy of improving quality of food products until 2030", signed in July 2016 by the Prime Minister Dmitry Medvedev. The main conclusions of this work are the following: first and foremost, the strategic goals of the Russian agriculture should be based upon the provision of food security, reduction in the product cost, increase of the volume of the ecofriendly products, as well as the regional development and improving of the living standards in them. The scientific novelty of the research along with the author’s special contribution consists in the cumulative study of the question from the provision of retrospective and current conjuncture with regards to the problem of food security.
Syromyatnikov Y.N. - Ways to Reduce the Specific Pressure of Wheeled Thrusters on the Soil pp. 95-103


Abstract: The subject of the study is the ways to increase the efficiency of transport vehicle and traction vehicle with dual wheels in different modes of operation (transport, working, traction). The object of the study is the system of twin wheels with the ability to adjust the area of contact with the soil for operation in different operating modes. The state of the soil in the process of its re-consolidation by the running part of mobile agricultural machinery clearly indicates a close correlation between the change in the mechanical, technological, biological, chemical, morphological properties and economic indicators of the soil state, and, consequently, the level of environmental safety of used mobile agricultural machinery, including the composition of soil cultivating units. The research methodology is based on analysis and synthesis, generalization of practical experience, graphic representation of the information received. The urgency of the study is determined by the need to ensure environmental safety, soil conservation, increase the fertility of agricultural land in the modern world. The scientific novelty is that the use of dual wheel systems with the ability to adjust the contact area with the soil for operation in different operating modes will make it possible to abandon the use of expensive caterpillar thrusters.
