Farms of Krasnodar region purchase cattle of milk, combined and meat direction of productivity. Imported cattle are accompanied with documents which differ from analogous ones specified in such cases by pedigree service of Russia. There were studied 1000 heads of symmental cattle of milk-meat direction of productivity imported from Austria. More than 5000 kg of milk can be obtained from cattle of symmental breed of milk-meat direction of productivity, except it they show enough high meat productivity. The analysis of accompanying documents on purchased cattle is joined not only with language barrier but with the lack of knowledge of adopted abbreviations, contractions and other attributes used by foreign breeders abroad. Having studied the accompanying documents connected with hereditary information of purchased cattle there was determined that imported heifers and their mothers were obtained in Austria, and mothers of bulls on 55,5% obtained in Austria and 41,6% in Germany. So, on formation of imported micropopulation of cattle greatly influenced the breeding school of Germany. In accordance with the adopted classification in Austria due to revealed cases of adoption of Holstein blood, there is a ground to consider the present herd as a belonging to the group of pure breed of symmental cattle and in prospect to conduct the mating of cattle with pure breed symmental oxen with the aim of absorption of mixtures of Holstein blood in pedigree. The researches determined that one can purchase the producers with characteristics of milk productivity at daughters of oxen not lower than Austrian indexes on voluminous milking and German – on milk quality, the purchase of symmental cattle from other countries must be subjected to this demand.

It presents a general structure of the rules base, conditions of execution of each rule of conclusion. To accelerate the work of intelligent system a parallel search for the rules in the knowledge base is to be applied. In conclusion, the algorithm of parallel search is described
The essential part of a soil cover of the Republic of Adygea is occupied by gray forest soils. Thus they still remain a little studied, including concerning their resistance to chemical pollution. Contamination of gray forest soils of Adygea with Zn, Cd, Mo, Se causes deterioration of their biological properties. In most cases, the degree of reduction of the values of biological indicators is directly dependent on the concentration of pollutant in the soil. According to the degree of toxicity to the biological properties of the investigated elements form the following sequence: Se > Zn > = Cd > Mo. Biological parameters investigated in research (activity of catalase and dehydrogenase, cellulolytic ability, abundance of bacteria of the genus Azotobacter, radish root length) may be used for purposes of monitoring, diagnosis and regulation of chemical pollution of gray forest soils Zn, Cd, Mo, Se
The process of the presowing seed treatment with alternating electromagnet field of the commercial frequency (EMF CF) 50 Hz is economically efficient. The use of the EMF CF 50 Hz in the unit with ring pole pieces allows increasing the germinating energy and power. The electromagnet seed treatment in the units with ring pole pieces is the perspective process of the presowing treatment which does not make unhealthy influence on the operating personnel. At the presowing treatment we have to take into account three factors, they are the arrangement of seeds in the working chamber, the time of treatment and the seed humidity. In this article the authors recommend to promote the unit consisting of a magnetic circuit with ring pole pieces of the rectangular cross-section, a magnetizing coil and an embedding of the non-magnetic material in the working chamber which allows increasing the germinating energy of spring barley by 10% and the germination by 7%. As field experiences have shown the highest seed germination and good crop capacity take place in the work chamber zone with boundaries R1=0,012 m and R2=0,035 m at seed humidity from 12% till 18% and the time of seed treatment is 0,9-2,75 s. The addition to crop capacity has run to 7% as a result of the spring barley treatment

The article highlights the food value of buckwheat. It is said that the achievement of its biological potential under prevailing conditions of cultivation is impossible without the introduction of modern scientific and technical progress. The authors describe variants of integrated application of growth stimulants and microfertilizers in buckwheat production technology. Recommended technologies have been tested in conditions of the Central Chernozem region. It is revealed that the best variant of pre-sowing seed treatment is the combination of Epin-extra and Rexolin ABS. Conbination of Epin-extra and Speedfol B is the best variant of treatment of vegetating plants, providing the maximum yield increase in comparison with control variant (without treatments). Economic efficiency of all proposed technologies was studied. The system of indicators was chosen, which evaluate the efficiency of 36 variants of seed and plant treatment with growth stimulants and microfertilizers. A comparative analysis of variants demonstrated that the application of Speedfol B in combination with EPIN-extra and Rexolin ABS is most cost-effective and profitable. It is noted that the final choice of combination of growth stimulants and microfertilizers will depend on the specific conditions of cultivation. Recommendations are given
Currently, for producers of mineral fertilizers one of the main tasks is the process of creating a supply chain of mineral fertilizers delivery to agricultural consumers, running on a «Just-in-time» way. The effective operation of such a supply chain has to be influenced by many factors, including: the technology of agricultural production, seasonality of agricultural work, the structure of the distribution channel of mineral fertilizers, the geographical features of consumers, the availability of appropriate infrastructure, etc. Critical elements of the infrastructure are warehouses and equipment for storage of mineral fertilizers, as well as the road network. For example, farms in the Rostov region were analyzed for the infrastructure necessary for the successful supply of mineral fertilizer agricultural consumers. It was found that the capacity of warehouses and facilities for the storage of mineral fertilizers and distribution of cultivated areas between agricultural enterprises of different size are diametrically opposed. The process of delivery of mineral fertilizers need to be developed taking into account the shortage or complete lack of storage capacity for their storage, especially for small enterprises. The existing road network, with paved allows us to deliver of mineral fertilizers virtually all consumers by road transport. This dictates the feasibility of delivery of mineral fertilizers to consumers by road transport in soft containers (Big Bags), allowing the storage in the open air
Theoretical, transformational and practical provisions for the development and regulation of small businesses and farms in the country's economy and agriculture are being cleared up. In the process of studying the problem we used logical reasoning, methods of comparing, and monographic, economic and statistical methods also. It is shown that small farming forms (SFF) in agriculture are essential for progressive development of agriculture, which is now recognized as a growth point of import substitution in all national economy. Given the author's interpretation of the category definition "small farming form" in agriculture differs from other definitions, in a more complete evaluation and statistics, provisions regarding private cottages and households as the SFF, their locality of functioning, independence in taking risks, increased adaptation, economic and legal binding, spectrum of production. The article shows the history of definitions of small business and small farming forms, stages of small business development, the scope of its practice abroad and in our country. It is said that a leading role in the formation of small farms belonged to households, which are still playing a leading role in production of agricultural products for their own consumption (without selling on the market). It is noted that at the present stage of industrial transformation of small businesses and small farms they often have a low mechanization level, high cost structure of manual labor. They have problems in adapting to the sector of services, in embedding into a complex system of relationships with medium and large business on the basis of technological specialization and also promoting innovation. It is emphasized that today the growing role of small businesses, small farms makes it more pragmatic to assess the prospects of development of this sector in our country
Efficient dairy cattle breeding are largely dependent from technology content and service animals. Most farms use a tethered way content. With this method of milking, the technology requires the introduction of new techniques to increase productivity on the farm and cost reduction of dairy products. The most rational is improving the design of existing milking machines. Regarded device for automatic removal of hanging part of a milking machine, its structure and working principle. The main unit of the device is a pneumatic motor that operates from the vacuum system of the milking plant. In the housing mounted on the shaft of the pneumatic motor rotor with curved vanes, there are magnetic elements. These elements should have the necessary geometrical and force parameters to ensure the normal operation of the device for automatic removal of hanging part of milking machine. The article describes a laboratory research and an analysis of the magnetic elements. In laboratory studies, we have revealed a dependence of the traction capacity of pneumatic motor from linear and power parameters of the magnetic elements, as well as established necessary geometric parameters and the magnetic field strength of the elements for normal operation
