Development of management system in agroindustrial complex of Belarus
The paper demonstrates summarized assessment of the existing management system, representing its drawbacks and discrepancies. Also the models of a perspective organization of management in agroindustrial complex regarding the development of market relations are formed. A special attention is focused on the development of bases of a new paradigm of management in agroindustrial complex. On the basis of this paradigm conceptual frameworks of building an effective system of management in agroindustrial complex in the republic, district and at an agricultural enterprise are formed. Besides, possible and reasonable models of a perspective organization of enterprises for a group of financially and economically stable entities are presented.

National food competitiveness: its condition and regularities of development
The article deals with the essence of the strategy of national food competitiveness (NFC) which enables to establish that the innovative constituent is an integral part of competitive benefits formation. That is why the innovative way of development, in spite of the difficulties of its implementation, is a principal strategy of an advancing development of agriculture. The essence of the innovative activity of different spheres of agroindustrial complex in the aspect of strengthening of national food competitiveness is identified. The most important characteristics of NFC are efficiency and competitiveness reflecting the conditions and regularities if its development which together form the process of production. The above mentioned characteristics allow to research economic process, methods and regularities on NFC strengthening.

Influence of brewing barley fertilization on technological characteristics of malt
The results of the experiments on sod-podzol light loamy soil with a high fertility level on the study of the influence of different forms of complex fertilizers with additives of microelements (copper and manganese) with their application in soil on the yield and quality of malt from brewing barley grain of ataman and browar varieties show that the application of new forms of fertilizers with additives of microelements in the technology of brewing barley cultivation ensures the increase of yield by 3.3-6.1 c/ha (with the yield of 60.2-60.0 c/ha of ataman barley and by 42.7-46.0 c/ha of browar barley) in comparison with the mixtures of standard fertilizers. The best complex fertilizers with microelements on these soils are the following: N:P:K = 9:13:18; N:P:K = 13:19:25; N:P:K = 10:16:19. They ensure the grain increase within 4.2-6.1 c/ha and quality grain indices (protein and starch content) and malt on the level of required standards.

Comparative biological value and amino acid composition of cereal and leguminous crops depending on application of mineral fertilizers
The research shows that application of mineral fertilizers to sod-podzol soils promotes the increase of the content of limiting and essential amino acids in the grain of cereals and leguminous crops. The grain of soya, vegetable legumes and winter triticale turns to be the best in respect of balance of amino acid composition and biological value of protein which corresponds to the standards recommended by FAO and WHO on the content of essential amino acid.

Characteristics of adaptability and grain productivity of tetraploid varieties and samples of buckwheat differed by plant morphotype
The analysis of fifteen varieties and breeding samples of buckwheat has shown that most of tetraploid populations have a high potential of grain yield, however, not all of them ensure sufficiently high stability of the given characteristic in changeable environment, what is reflected in a sharp reduction of the yield level in less favourable years. It is necessary to select not only high-productive varieties, but also to develop populations with high homeostasis of fruit formation, especially it is required for forms with determinate type of plant.

Phytomonitoring of cranberry tree plantations (Viburnum opulus L.) in Belarus
The research of the specific composition of phytophages in cranberry tree plantations and substantiation of the system of optimization of their phytosanitary condition with the use of biological preparations show that the main pests both by incidence and number in Belarus are water elder leaf beetle – Galerucella viburni Payk., beet aphid – Aphis fabаe Scop., rose leaf roller Archips rosana L. Seldom damage is made by European fruit lecanium - Parthеnolecanium corni Bouch. The application of a biological preparation melobass, manufactured on the basis of Beauveria bassiana ensures water elder larvae decrease by 68.5–71.4%. The efficiency of the experimental sample of lecanicyl preparation produced on the basis of high-effective strain of fungus Lecanicillium (Verticillium) lecanii (Zimm.). Zare et W. Gams st. BL-1 against beet aphid reaches up to 59.5–65.5%.

Peculiarities of microelements accumulation in fruits of cornelian cherry varieties of Ukrainian breeding introduced in the conditions of Belarus
The article describes the results of a comparative study in a two-year cycle of observation of the content of microelements in fruits of the natural wild form of Cornus mas. L. and its 5 varieties of Ukrainian breeding (Vladimirsky, Vydubetsky, Eugenia, Lukianovsky, Radost) introduced in the conditions of Belarus. Distinct genotypic differences in the parameters of their accumulation, which depend to a great extent on weather conditions during the vegetation period, are identified. It’s shown that the highest content of nitrogen in fruits is observed in Vydubetsky and Radost varieties, that of phosphorus ― in Radost, that of potassium ― in Vladimirsky and Lukianovsky, that of calcium ― in Eugenia, while there is no distinct genotypic differences in magnesium content. Most of the introduced varieties of cornelian cherry, especially in the first year of study, exceeded its natural form in the content of nitrogen and phosphorus in their fruits, while potassium and calcium content showed an ambiguous direction of differences. As far as magnesium content is concerned, there were no differences observed. At the same time weather conditions of the vegetation period not only determined to a great extent the parameters of microelements accumulation in Cornus mas. L. fruits, but had a considerable impact on the extent and direction of differences in their content in variety forms and in the natural form.

New concentrate in the composition of whole milk experimental substitutes at calves breeding
The research shows that the increase of the content of components from biologically valuable domestic raw materials in the composition of experimental types of whole milk substitutes (WMS) ensures the reduction of their price (by 22–27%) in comparison with actually used substitutes (analogues). Unsoldering of calves with cheap experimental types of WMS with highly nutritious extruded concentrate on the basis of flax seeds promotes the increase of daily gain by 14%. As a result, the payback of experimental types of WMS has raised by 1.5 times as compared with the substitutes used actually in Vitebsk oblast (“Vitamilk-P3” and “Telenok-K23/12”).

Use of rape oil distillate in poultry keeping
While studying the composition of distillate to be formed in the course of physical refining of rape oil it’s determined that the content of tocopherols in distillate is 1.8–4.0%, phytosterols – 6–12%, free fatty acids – 74–84%, including 42.2–54.6% of oleic acid, and Vitamin F (linoleic and α-linolenic acids) – 20.2–26.0%. It is shown that the use of distillate as a vitamin-containing concentrate for broiler chicken fattening allows to increase poultry safety and average daily weight gain, as well as decrease cholesterol and total lipid content in blood serum and meat of poultry, at the same time feed consumption is reduced and nutritive quality of poultry meat is increased.

Gearing with high contact ratio (HCR) has other properties then gearing formed with the standard shape profile. It is characterized by increased load capacity. In this paper the solution to the problem of stress concentration in the root of gear is based on the boundary element method (BEM). HCR-gearboxes with tooth fillet of multiple contact remain unchanged.
