06.00.00 Agricultural sciences
DescriptionWe attempt to combine professional agronomic knowledge with familiarity with graphic art presented in the form of a poster in the paper. The term "poster" is considered a large loose-leaf edition, combines visual and typographic elements and execute graphic communications. The main idea of the poster is to convey the information to the reader quickly and accurately. In the study of the material we have formed complex scientific and educational resources on the history of agricultural science, including the history of the popularization of agronomic knowledge. In our work, the poster is treated as an object of analysis, as the material of social and cultural analysis and as a tool to gather information on the development of agronomic knowledge through their visualization. In the course "History and methodology of scientific agronomy" one of the competencies of students is familiarity with the methodology popularization of agronomic knowledge, understanding of what is happening. In this regard, an attempt was made to consider the Soviet poster as a source of information on the development of scientific agriculture in the period from 1917 to 1980. The aim was to analyze the main events of this period, elements of the technology of agricultural production, species and varietal diversity of crops, as well as various events in the agricultural sector. The article considers four basic types of posters: promotional, political, instructional, scientific and educational. Each of these types of posters performs its function. The poster covered all stages of agrarian sector of the country, was a historical reflection of the Soviet period and always remained mobile, online and popular art form. Today, his role is small, because it has changed the ways of presenting information. However, its historical role unchanged, he has served as the Foundation of the modern advertising industry, including agronomic knowledge

DescriptionThe results of study of groups and forms of iron compounds in leached chernozemic soils of Western Ciscaucasia for three crop rotations according to scheme grain-grass-hoeing are presented. With long-term use of leached black soil in terms of Agrigento there is a substantial change in the contents of the various groups and iron compounds. On the non-fertilized variant of rotation, the total content of this element in the 0-20 cm 21-40 cm soil layer by 69.4 and 66.5% of silicate and by 30.6% and 33.5% free group of compounds of iron. The applied system of fertilizer crop rotation helps reduce the silicate and increase of free group its compounds. In leached black soil a group of desilicated iron in the 0-20 cm layer 24.8 % presents crystallizability and to 75.2% amorphous compounds, 21-40 cm layer, respectively, 26.2 and 73,8 %. Under the influence of fertilizers we have noticed increasing of amorphous and reducing the number of cristallizing forms of the compounds of this element the soil. The number of different groups and forms of iron compounds in leached black soil with systematic use of fertilizers in crop rotation is determined not by the size of introducing this element as impurities, and processes such as the alienation of iron with additional derived products, increase its mobility in the soil due to a shift in the reaction of the soil solution, changes in fractional-group composition of humus. Diagnostic criteria state of iron in the soil are leached quantitative ratio of the content of the various groups and forms of the compounds of this element

STATUS AND PERSPECTIVES OF DEVELOPMENT OF DAIRY CATTLE IN THE ROSTOV REGION
DescriptionIn this article we carry out the analysis of the current state of dairy farming in the country and in the Rostov region. The article shows the number of cows and milk production in farms of all categories in the country and the region. At present, Russia is ranked 6th in the world in milk production and is the largest importer of milk and dairy products. The situation is similar in the dairy industry of the Rostov region. Nowadays Rostov region ranks 5th in the Russian Federation and 2nd place in the southern Federal district in milk production. A large portion of milk (83,4%) is produced in households. This indicates decentralization of livestock complex in the Rostov region. The demand for milk is met through own production by 83%. Currently, the region has just started a period of stabilization of the gross milk production. For the last 4 years the indicators of milk productivity of cows have been 13.0-14.5% higher than the national average. Much of this was facilitated by the measures of state support. With the support of Federal and regional authorities in this field it has been created a favorable investment climate for the development of dairy farming. In the article the main organizational and economic aspects of profitability of milk production have been shown. It identifies the main issues that hinder the intensification of dairy farming. The dairy sector of the Rostov region has good prospects. Main approaches to the solution of the problems of development of dairy cattle breeding in the Rostov region have been listed

STATE OF THE RUSSIAN MARKET OF SUNFLOWER SEEDS
DescriptionThe article presents characteristic of the Russian seeds market as one of the main factors of the efficiency of domestic agriculture. The dynamics of sunflower acreage, a tendency to reduce them, the major factors that influenced the current trend were examined. The dependence of the dynamics of sunflower yield on the share of imported seeds used for its cultivation was revealed. The article showed the main problem of domestic seeds and identified current trends. The structure of costs in the cultivation of domestic and imported sunflower hybrids in different economic conditions was shown; the efficiency is calculated using a variety of technologies. Based on the calculations we have made conclusions and determined the prognosis for local farmers on the basis of current market dynamics. The article has shown guidelines for state support for the industry to address the problems for which the Ministry of Agriculture had developed a strategy of breeding and seed production of major crops until 2020. The necessity was shown for Russia's membership in the international system of quality certification of seeds OECD (Organization for Economic Cooperation and Development), which will implement domestic seeds in the European market and make domestic seed production more competitive. Indicated the need for close cooperation between business, science and educational institutions, participation in international educational programs, bringing to research the most promising students to form staffing

DescriptionThe article presents materials on comparative study of the nutritional value of chickpeas and peas which are widespread in the arid zone of the Southern Urals. The scheme of the scientific and economic experiments involved the assessment of yield formation of chickpeas and peas during the vegetation. The study showed that different varieties of chickpea and pea have considerable difference in the content of nutrients. The amount of crude protein in the pea grain ranged from 25.1 to 26.8%, and chickpea – 21.7 - 22.9%. With regard to the fat, its highest concentration was in chickpea grain - 3.63%, on average, which is 1.16% higher than on average in the pea grain. The chemical composition of the pea and chickpea grain of different varieties points to differences in their composition and homogeneity within the culture. Basing on the study, we recommend to sow chickpea and pea grain in the middle of May to obtain the highest yield, this, in turn, has a positive effect on the nutritional value of the crops. When selecting plants for cultivation in the conditions of the Southern Urals, it is preferable to choose the variety of Madonna pea, which has a higher potential for yield than the chickpea variety Krasnokutsky-123. It has been experimentally found that chickpea grain has better moisture-retaining power in a bound condition during the vegetation period as compared to the relevant characteristics of pea grain, which is a positive drought-resistant value of crop. In structural elements of the harvest the peas showed the trend of the highest rates in comparison with the corresponding elements in chickpeas

FODDER AMINOACID COMPOSITION COMPARATIVE ANALYSIS
06.00.00 Agricultural sciences
DescriptionThe right balance of essential amino acids and protein is the main condition for the optimization of weight gain, feed conversion and high profits. In VGC "Megamix" the quality of different types of raw full-fat soy, wheat, corn, meat and bone meal and fish was assessed on the content of amino acids on the IR analyzer of FOSSNIR Systems company. Amino acid content in the feed does not always match the average standards of reference. So in the reference data content of methionine, threonine and phenylalanine in wheat, indicated 0.23%, 0.43% and 0.64% respectively, and studied in the laboratory of VGC "Megamix", respectively, 0.24%, 0.45% and 0 73%, that is 0.01%, 0.02% and 0.09% higher of tabular values. The lysine content of the wheat to be investigated in a laboratory and provided in the averaged data was on the same level. Thus, the calculation of the recipes should be carried out taking into account not tabulated values but the actual, which will reduce the so-called "safety stock" to get food of consistent quality and reduce the cost of the cost of animal feed, which in turn affects the economic efficiency of livestock production

REQUIREMENTS AND CONSTRUCTIVE DIFFERENCES OF A STATIC CONVERTER
DescriptionIn this article technical requirements to static converters are examined. We can treat as the basic parameters: efficiency and quality of a target voltage. Weight-dimensional parameters, reliability, maintainability are basic operational parameters, as well as target capacity, size of an starting and target voltage belong to key parameters of static converters. As a rule designing of converters is a uniform constructive complex. As at designing, time of an operating time until first failure is taken into account, time of guaranteed work of the separate elements included in the static converter, are determined on the statistical data. Failure of separate elements of parts of converters are possible because of internal (time of guaranteed work) and external (short circuits, overloads) factors. In the article we have offered the ways of reduction of influence of external factors (for example, we used high-speed automatic switches or iterative static converters in which parts of a power circuit were included in parallel). Using universal static converters allows raising some parameters of efficiency simultaneously. In the article we have also considered a scheme of the iterative converter with variable structure which allows (depending on start and target conditions or requirements) forming an output capacity of the required level and quality without constructive change

Description
The constitutional regulations of all countries guarantee their citizens the right to education. In the Republic of South Ossetia during last years we observed a process of modernization of the state. In particular, the legislation on education directed on guaranteeing the right of citizens for education has been developing. The state defined the main directions of a development of education, material and personnel resources, and also the problems in this sphere were revealed. One of key problems is insufficiency of financing of an education system which doesn't allow guaranteeing the right for education at the necessary level. The availability of educational institutions for students is essential to guarantee the right to education. Modern states establish minimum standards for primary, secondary and higher education. Thus, primary education must be universal, compulsory and free, and in case of its absence, elementary education should be encouraged or intensified. In the secondary, including vocational, education guaranteed openness and accessibility for all, including through "progressive introduction of free education". In the Russian Federation, the availability of educational institutions for students was solved comprehensively, but mainly due to the municipal reform, according to which the territory is rural and urban settlements were formed taking into account walking distance from the administrative center. The author proposes to consider similar experience for South Ossetia

APPLIANCES, TECHNOLOGIES AND EQUIPMENT FOR HAULING OF FRUIT OUT THE GARDEN
DescriptionAn integral part of technological process for the cultivation of agricultural crop is the transportation issues. For their execution, we require significant energy and labor costs. The statistics show that the proportion of expenses for transportation of goods in agriculture reaches 25-40% of the total costs for ready-to-sale production, when the proportion of farm tractor transportations reaches 60% of the total. Thus, there are considerable losses of production, reaching in separate cases up to 50%. They are especially great in the harvesting and post-harvest cycles of crop production which is connected with crop damage during transportation. Large losses of fruit and vegetable products when transporting might be connected with their mechanical damage level during loading, unloading and transportation. This causes the urgency of the problem of preservation when transporting fruit and vegetables. One of the prior national issues is "... the development of directions to improve road transport maintenance with the aim of improving the quality of the transport process, which includes increasing commercial speed of freight flows by 2-3 times, increase productivity and profitability of road transport systems by 2-3 times, reducing the environmental load on nature by 20% ... " and others mentioned in the "Transport Strategy of Russia until 2020"
