The article by continues the cycle of their studies related to the formulation and development of methods of constructing non-negative solutions of inverse problems of balance models (in this case, the model of world trade). Method of constructing nonnegative solutions of the studied inverse problems is developed. This technique is based on the following scheme of the solution. Initially we convinced of a correct formulation of the direct problem, then of the solvability of the inverse. Further, by specified tabular solutions of the direct problem, a system of algebraic equations containing the unknown, the estimated parameters of the studied model is built. Then the inverse problem reduces to solving the following quadratic programming, the solution of which is determined in MS Excel. The theoretical material is accompanied by solution of specific example, using statistical data of the Karachay-Cherkess Republic that shows how actually in practice it is possible to solve the inverse problem, i.e. to organize a process of balanced trade of the Karachay-Cherkess Republic with each of the subjects of Noth – Caucasion Federal District. Found the non-negative elements of a matrix, by which we can judge what proportion of national income, y, the subject has to spend on the purchase of goods in the Karachay-Cherkess Republic, to trade between this pair was balanced. So, the inverse problem posed in relation to the trading countries, it is possible to put and solve the following method and to trade between the subjects of one country

The results of the economical and bioenergetics effi-ciency estimation of using fertilizers of various winter barley sorts in the conditions of the South part of Ros-tov region are given and optimal variants of their usage are determined

The main topic of the present article is the perspective of the economic development of the hospitality industry in the Krasnodar region by the means of development of the accessible tourism for disabled people

The article considers current economic situation in the economy of the Krasnodar region, the importance of import substitution in the future functioning and regulation of regional development of agro-industrial complex. The positive impact on the agricultural economy, double sided grocery sanctions, the leadership of the rural economy of the region with annual growth of GDP of 9.2% (in Russia – 4,5%) is pointed. The article shows that the growth of quantitative and qualitative indicators in the industry was provided with additional targeted investment to increase profitability of crop production to 44%. The advantages of big business that produces mostly grains are pointed out, because this factor will continue to determine the vector of development of agriculture. A big positive point of the livestock industry is the growth of profitability of milk production to 37%. At the same time, cattle breeding with the margin of 19.7% is still highly problematic on observance of technological discipline. Production of cattle meat remains unprofitable. A significant segment of production in farming is still taken by small farms. In 2014 the government regulated their development supporting them with money in the amount of more than 700 million RUB . The author believes to keep further growth of the livestock on it is necessary to stabilize the number of livestock, especially dairy cattle, to restore the production of pork, to continue the construction and reconstruction of farms and complexes, to provide animals with high quality food. The author also stresses the importance of development of business of rice growing, vegetable growing, fruit growing, the importance of updating and development of material and technical base. The work provides the data that at the expense of state regulation (support) profitability of agriculture in the region has grown by an additional 7%, so it creates new opportunities for growth of the agricultural economy of our region

It is noted that the grain commodity market is the basis of the Russian agro-industrial complex. Earlier the state support was about $4 billion, in 2016 it is expected to reach 237 billion rubles (less than $3 billion). Russia's accession to the WTO brought its farmers more minuses than pluses, less regulation opportunities, protection of the market. The urgency of improving the development methodology, development of practical recommendations for the decision of efficiency enhancing of the grain market, increased due to the globalization of socio-economic processes in the world. Over the last 5 years in the Krasnodar region state support of agro-industrial complex amounted to 32 billion rubles ($0.4 billion), or 1 664 rub/ha ($20/ha) in 2014. Today, once again the growth of prices for supply of industrial resources has overcome the growth of prices for production of agriculture products that seriously has limited the development of the agro industry. The authors consider that the success of the grain industry depends on combination of the following factors: 1) modern equipment and technology; 2) qualified professionals; 3) state financial support; 4) reasonable credit resources. Now nobody needs production at any cost, it necessary to lower the cost of grain, to get the maximum profit and invest it in modernization of the enterprise. To increase productivity, to produce more at a less cost. For producers of grain it's time to invest in the development of their own livestock, or they will be late for this growing market. This vector of development will improve the stability of the grain business and the accompanying livestock, will reduce the seasonal dependence of financial flows, reduce unit costs, increase profitability, competitiveness, expand business, create new jobs, increase the number of its buyers

In the article, we used methods of economic calculation for optimization of the installation project of mini hydroelectric power station for agricultural producers in Kirov region, which allowed to estimate efficiency of their introduction, considering three possible variants in the cause of events

The content of ascorbic acid (AA) and glutathione (GSH) in spring barley seed of four varieties depends upon hydro-temperature environment (HTE) in different way. The genotype and HTE have equal input on AA content (35 and 34,8 %), and GSH content depends mainly upon “genotype-HTE” interaction (67,6 %).

Significant changes in mountain ecosystems occur after deforestation on limestone massifs of the Western Caucasus. Tall-mountain-meadow vegetation with a large variety of species formed at low and medium soil disturbance 3 years after logging. Physical and biological properties of calcareous soils also vary greatly. The values of biological activity decrease at the maximum load is more than 10 times. Biological activity is increased by 20-50% or more cutting stations with low disorders. Biological properties of soils (especially the enzymatic activity) are very sensitive indicators of changes that have occurred as a result of logging. Changes in the activity of soil hydrolases different from changing oxidase activity at different times after logging

Education plays a central role in shaping personality. Moreover, the particular importance are the values and ideals, which are formed through a process of education and training. Today the moral component of the education system is one of the priority tasks of the state

The article examines the role of metadata in the use of networked information resources in the educational process. We have put the problem of creation and use of metadata for educational musical culture, as well as we have outlined the ways to develop common requirements for such sites
