The model of the turbulent boundary layer over a rough surface is presented. The model is based on the special type of transformation of the Navier-Stokes equation. The turbulent boundary layer in this model is considered as a flow above the rough surface gener-ated by the viscous sublayer (the dynamic roughness effect). The roughness density effect on the shift of the mean velocity logarithmic profile has been estimated in the case of 2D and 3D roughness elements
The completely closed model of wall turbulence was derived directly from the Navier-Stokes equation. The fundamental constants of wall turbulence including the Karman constant have been calculated within a theory. This model has been developed also for the accelerated and non-isothermal turbulent boundary layer flows. The estimated mean velocity, temperature and impurity concentration profiles as well as the spectral characteristics of the streamwise velocity component are to be shown in a good agreement with the experimental data

At the contaminated by Аmbrosia artemisiifolia fields, a mineral food increase promotes decrease in productivity of sunflower in a greater degree
Competitive relations between various kinds of weeds in sunflower crop and influence of connatural factors on its constipation are considered. Specific weight of each kind of a weed and its change throughout a vegetative period, and also influence of gramineous weeds on efficiency of breeds and hybrids is defined. The economic threshold of injuriousness of gramineous weeds in sunflower crops is defined

As a result of this work, the efficiency of influence of harvest date of fruits on quality and duration of storage in usual atmosphere is proved
“Professor Elena Zakharova” variety is a hybrid between Aigeorgitico and Cabernet Fran, which was made in the result Greek-Russian creative scientific cooperation. The period of production is 156-165 days. The growth of arms is fast. The degree of ripening is higher. The percent of fruitful arms is more than 90. The yield is high. The average weight of cluster is 260 g. It has high resistance to cold, drought-resistance and higher resistance to mushroom diseases. The leave is average, symmetrical, average parted, five lobes. There are two inflorescences on one arms - 4 and 6 on the nodes. The flower is hermaphroditic. The cluster is middle, cylindroconical, middle density. The berry is middle, round, blue-black color. The pulp is juicy, with solanaceous taste. The sugar content is high. This variety is developed for producing dry red wines of perfect quality
In this innovation section there are necessary agrotechnical receptions of care by the vineyard bushes, providing reception of high and qualitative crops of grapes. First of all, these are gartering of sleeves, fruit arrows, vegetating arms; operations with green bodies of a bush, fragmentation, extrapollination, stopping, girdling, stamping, etc., and also mechanization of care works
Vitis vinifera subsp. silvestris Gmel. is the wild subspecies of Vitis vinifera L. and an important source of genetic resources for grapes breeding. Currently, this form is very rare in the world. In this paper, conducted the first study of wild grapes which was found in the North Caucasus with the use of two microsatellite markers. The study have shown a high level of genetic diversity: intrapopulation variability was 75,2%, the interpopulation variability accounts was 24,8%. All populations are characterized by certain unique genetic structure and may be as donor of resistance genes which have a long-term evolutionary selection
Two methods were used for DNA extraction from herbarium leaves of two subspecies: V. vinifera subsp. sativa D.C. и Vitis vinifera ssp. silvestris Gmel. DNA extraction is difficult from herbarium leaves plants because of the presence of metabolites that interfere with DNA isolation procedures and downstream applications such as DNA restriction, amplification, and cloning. The quality of DNA was checked on a spectrophotometer by measuring the level of absorption at A260/280 nm. The results showed the successful extraction from mature and dried leaves of DNA when using the СТАB-method №2. Another method hasn’t shown satisfactory results in amplification of DNA
Results of research of influence of foliar top dressings by Zitovit and Zircon preparations on development of plants of grape of Berlandieri × Riparia Kober 5ВВ grade on sandy soils are submitted. Processing of plants with Zitovit in conditions of their insufficient mineral nutrition through roots, improved their growth and development. Action of Zircon preparation for raising immunity promoted qualitative rearrangement of morphological parameters of development of plants
Necessity of application of Emistim preparation at various stages of clone micro reproduction is investigated and proved: induction of meristems into culture, micro reproduction itself, education of roots and micro grafting

In the article the management problem of agro-industrial holding is formulated in a general way, which is, on the one hand, it is necessary to produce recommendations about holding management, where its adaptive model is necessary, and, on the other hand, the construction of its model is inconvenient because of high complexity and dynamism of internal logistics of the object of management, its territorially distributed and diversified character, a large quantity of the economic indicators characterizing its activity at various levels of its organization. The general method of the decision of the formulated problem by using the systemic cognitive approach is offered

The essence of perspective method of Direct-costing" consists of use of direct variable expenses which directly concern on production cost price (so-called relevant expenses), not only for the account, but first of all as factors of management of volumes of manufacture of various kinds of production. However this method has a number of lacks: first, this analysis is carried out within the limits of system of controlling of the enterprise, instead of branches and diversified agrarian and industrial complex of region; secondly, in calculations of this method is accepted, that production volumes linearly depend on expenses for its manufacture that is true only at extensive evolution of manufacture, in the narrow limits defined enough at which manufacture volumes can increase extensively without technology and organization change; thirdly, in calculations of this method the force and direction of influence of factors, and also a kind of function of this influence is not defined. Overcoming of these lacks could raise efficiency of the Direct-costing method and expand area of its application. However, this problem was not set and was not solved, first of all, because of absence of a corresponding mathematical method, and also program toolkit realizing it and a technique of its application. In this work the given problem is set and its complex decision is offered. Numerical examples are resulted
