01.00.00 Physical-mathematical sciences
DescriptionThis article is a continuation of the previous works of the authors [The influence of reaction dissociation / recombination of molecules of water on transportation of electrolyte 1:1 in the membrane systems in the diffusion layer. Part 1. Mathematical model // Scientific journal of Kuban State Agrarian University, 2016. No. 07(121) and The influence of the reaction of dissociation / recombination of molecules of water on transportation of electrolyte 1: 1 in membrane systems in the diffusion layer. Part 2. Asymptotic analysis // Scientific journal of Kuban State Agrarian University, 2016. – №08(122)] and devoted to assessing the possibility of gravitational convection due to the recombination of hydrogen and hydroxyl ions. The article presents the solution of a boundary-value problem, which is a mathematical model of electrodiffusion for the four types of ions at the same time (two ions of salts and hydrogen and hydroxyl ions) in the diffusion layer in electro-membrane systems with ideal selective membrane, with the heat transfer equation and the Navier-Stokes equation. The article shows the possibility of the emergence of gravitational convection due to the exothermic reaction of recombination of water molecules in the depth of the solution. The article considered the reaction of recombination of hydrogen ions and hydroxyl, although the main results can be applied, after appropriate modifications, and to amfolit-containing solutions, such as wine, juices, dairy products, microbiological processing of biomass (amino acids, anions of polybasic carboxylic acids), municipal effluent (anions of phosphoric acid), etc.

EXPLORING THE POSSIBILITY OF OBTAINING PECTIN EXTRACTS OF HIGH PURITY
DescriptionThe article describes a possibility of obtaining food pectin extracts of high purity form secondary raw materials such as sunflower anthodiа. The relevance of the use of pectin extracts as independent products or as an ingredient in food products for therapeutic and prophylactic purposes is determined by the high complexing ability of pectin substances in the dissolved form, in comparison with the commercial powder pectin. The use of pectin extracts reduces the cost of the final product by reducing the number of technological procedures. As dried plant material is mainly used for the production of pectin and pectin extracts, the article presents the study of the swelling process of dried and crushed sunflower anthodiа. It is established that the inclusion of the swelling process as a separate technological process for the production of pectin extract from the sunflower anthodiа is impracticable. The study on further processing of vegetable raw materials by electroactivated water system (EAWS) to reduce the content of ballast substances in raw material in relation to pectin and increase the purity of pectin extract is also presented. Some processing options of sunflower anthodia with EAWS of various рН were considered as well. The decrease in the content of dry substances in the processing of plant material that characterizes the decrease in the number of ballast substances is shown. We have also calculated the purity of the obtained pectin extracts

DEVELOPMENT OF AGRITOURISM IN THE YEISK DISTRICT OF THE KRASNODAR REGION
DescriptionThis article discusses the development of agrotourism and its benefits for the modern urbanized man. In the study, it appears that this type of activity has a wide range of targets in different countries. However, in Russia - it is not only a way of familiarizing travelers to rural life, but also an opportunity to create new jobs and new employment areas of the rural population, which is especially important in the current economic climate. The authors believe actual activation of this sphere of activity in the Yeisk district of the Krasnodar region, which is characterized by a diversified orientation of peasant and private farms, and which has a high agricultural potential. On the basis of the available resources of LTD "JASENSKIE ZORI" it is proposed to organize two options eco tours, designed for different times of the year (for the season June - September and October - May). Tours various programs planned, enabling and enjoy outdoor activities, and participate in the harvest, and get acquainted with the peculiarities of the region, its flavor and attractions. The features of this type of holiday are its democratic value, because it does not require large capital costs for the farmer, and the life of a rest close to the realities of rural life

Description
In recent decades, Russia has increased the demand for high oleic sunflower oil and, consequently, for the raw material from which it is derived – high oleic sunflower seeds. Currently existing methods of control of mass fraction of oleic acid in the seed oil of sunflower, have significant drawbacks, due to which sharply raises the question of the development of the Express methods of control of mass fraction of oleic acid. The study presents the results of determining the mass fraction of oleic acid in the oil of sunflower seeds, obtained by known methods (GC and ri), and developed a method based on NMR. The developed method of determining the mass fraction of oleic acid in sunflower seed oil has a number of advantages compared with the known: is not destructive (does not require the extraction of oil from seeds), does not require special sample preparation excludes the use of toxic chemicals, the analysis duration is 5 minutes, ensuring high representativeness of the sample, and the simplicity and automation of the analysis process reduces the requirements for qualifications of laboratory personnel. The developed method of determining the mass fraction of oleic acid in the oil of sunflower seeds can be carried out simultaneously with the determination of oil and moisture content of seeds on commercially available analyzers, but I hope it 1006М, which is currently applied at more than 250 companies of oil and fat industry

DEVELOPMENT OF RURAL TERRITORIES MANAGEMENT ON THE BASIS OF PUBLIC AND PRIVATE PARTNERSHIP
DescriptionToday we have built a successfully operated current management system for modern agriculture in the Russian Federation, which includes governance at all levels of government - federal, regional and local. Now there is an objective need for the transformation of rural territories and, in this regard, it is necessary to consider the effect of the potential of public-private partnership for the development of the managerial system. The priority is new approaches to the mechanism of management for villages, the need for public-private partnership as well as its impact on sustainable development of rural territories. The article describes the basics of management systems for rural territories based on a public-private partnership. We have analyzed the next concepts: managerial system, public-private partnership, program-targeted management, sustainable development оf rural territories. We have also studied a program-targeted management, which is a common and famous in the world, it has a major impact on the agricultural sector and rural territories development. The analysis results can be used in the processes of development and implementation of modern policies for the effective functioning of agriculture in the country and development of rural territories

INFLUENCE OF PREPARATIONS OF THE TRADEMARK “ECOGEL” ON THE GROWTH AND PRODUCTIVITY OF APPLE-TREES
06.00.00 Agricultural sciences
DescriptionIntroduction of new elements of fruit cultivation technology into production is one of the elements of intensification of the branch. The problem of providing plants with moisture is the key in modern technology. The purpose of the research is a development and manufacturing of innovative methods of water supply of modern fruit plantations. Researches were conducted in two fruiting zones of the Krasnodar region (Northern and Kuban) with the aim of assessment of influence of different ways of water supply on the growth and productivity of apple-tree varieties: Idared and Gala Schniga grafted on the stock М9 and planted in 2012 due to the scheme 3,5x0,8 m. There was determined that the application of the absorbent Aqua Life and absorbents with the addition of recommended elements (Ecogel-1; Ecogel-2) increase the acclimation rate of seedlings on 2- 6%. The presence of proper conducting system to supply with the moisture and nutrients the overhead part (roots-leaves) and a large number of photosynthezing apparatus promoted to obtain the high-quality fruit productivity, accumulation of phytomass and increase of fruit quality. We have found, that complexes of hydroabsorbents on the basis “Aqua Life”, “Ecogel-1” and “Ecogel-2” in conditions of Kuban in fruiting apple-tree plantations on dwarf stocks showed the high effectiveness on water supply, for the first time

Description
The article presents the results on the effects of Imazethapyr herbicide on aquatic organisms. The chronic toxic effects have been studied of the imidazolinone herbicide in a concentration range of 0.4 - 1150 mg/l to the representatives of various groups of aquatic organisms: zoobenthos – great ramshorn snail (Planorbarius corneus), zooplankton - Daphnia (Daphnia magna Straus), phytoplankton - protococcal alga (Scenedesmus guadrigauda) and macrophytes - higher aquatic vegetation (Elodea canadensis Michx). It is shown that the herbicide does not have a pronounced lethal effect to aquatic organisms tested. Their respective LC50 values are > 1000, 680, 510 and 910. Elodea is shown to be most sensitive to its sublethal effects (decreased growth of lateral and main sprouts at a concentration of 10 mg/l and more), reduced fertility was observed in Daphnia at a concentration of 300 mg/l and above, and as to the great ramshorn snail no sublethal effects have been revealed for all the concentrations studied
