With the possible radioactive contamination of the
territory, as a result of emergency situations at
enterprises of the nuclear fuel cycle, there occurs a
task of further use of the soil for agricultural purposes.
Researches on the cultivation on contaminated areas of
fruit plants in the conditions of the Krasnodar region
were not carried out. As a result of the experiment in
the field we received experimental material on
migration and 90Sr accumulation in vegetative and
generative organs of cherry-plum. Research lasted for
8 years. The accumulation of 90Sr, placed on the
surface of the soil, in the bark, wood, leaves, and fruit
was 7,0×102
; 4,8×102
; 9,7×102
and 1.8 ×102Bq/kg.
With the penetration of 90Sr in soil at 50 cm
accumulation in the bark, wood, leaves, and fruit were:
5,1×102
; 3,0×102
; 6,9×102
; 1,4×102Bq/kg. The
experimental material obtained in the field makes it
possible to calculate the coefficients of the nuclide
transition from polluted soil to the various organs of
the studied plant and to make a forecast of the possible
use of contaminated areas for the cultivation of fruit
crops. Radioactive contaminated areas cannot be left
without proper control, since, firstly, non-planted
fields are exposed to wind and water erosion of soils,
which leads to rapid and large-scale pollution of the
environment and, secondly, if it is possible to obtain
products from such fields, this should be done for
economic reasons
One of the promising directions of development of
agriculture of the Russian Federation is to increase
the production, improve the quality and decrease the
cost of potato cultivation. Annual cleaning is one of
the most intense and costly in transport and
technological processes. Potatoes - blending high
culture and very picky about cleaning. The highest
yields and income from potato production get where
embedded technology to optimize energy and labor
costs. The main (though not only) the special
technical means used during machine harvesting
potatoes, are potato harvesters. The main problem
when cleaning is a problem of balancing conflicting
requirements to the process and possibilities of
agricultural machinery. Including increasing the
purity of the tubers in the container with one hand,
minimization of losses and damages of tubers on the
other hand, when the performance of equipment. In
this article we propose a circuit-design solution
separating the working body of the potato harvester
that allow for cleaning to significantly reduce the
amount of traumatized potatoes in the process of
separating soil and vegetable impurities, creating the
preconditions for the elimination of damage to the
tubers on the hard side of the working bodies of
harvesting machines. Informed choice and timely use
of plug-in modules (separating working bodies) in
modern potato harvesting machines at work in
specific climatic conditions allows them to fully
match the list of regulated agronomic requirements.
Thus, the creation of new science-based technical
solutions for a separation of the organs of potato
harvesters is an actual scientific-technical task, which
makes a significant contribution to the development
of the country

The article continues the cycle of their studies
associated with the formulation and development of
methods of construction of nonnegative solutions of
inverse problems for dynamic systems. In this article
the authors formulated and investigated inverse
problems for dynamic systems: model of Samuelsson–
Hicks. The technique of constructing non-negative
solutions of the studied inverse problems. This method
is based on the following scheme of the solution. First,
we have to identify the formulation of the direct
problem, then the formulation of the inverse. This
work investigates how correct the mathematical
models describing the dynamic economic system are.
Further, in the specified tabular solutions of the direct
problem, we have built a system of algebraic equations
containing the unknown estimated parameters of the
studied model. Then posed inverse problem is reduced
to solution of a problem of quadratic programming, the
solutions of which are defined in MS Excel. The
theoretical material is accompanied by the specific
example
The relevance of the article is caused by the necessity
to form the linguacultural competence of foreign
students studying Russian language that corresponds to
the Contemporary didactics of foreign language
teaching. The case (precedent) texts are considered as
one of the main means of linguacultural orientation
used in practices of teaching Russian as a foreign
language. The necessity to study the case (precedent)
texts in this way is defined by its active use in
language and by the presence of cultural component
determining the valuable priorities of Russian vision of
the world. Therefore, the assimilation of case
(precedent) texts as actively used language elements of
Russian culture is the most important principle of
developing the communicative competence.
The aim of this work is the attempt to describe the case
(precedent) texts, acting as key material in the practice
of teaching Russian as a foreign language. The article
reveals the specificity of case (precedent) texts in the
context of national culture, it also identifies and
analyses their formal and semantic features, the
peculiarities of perception of the case (precedent) texts
by foreign students. The researching results of the
peculiarities of the case texts that are used in the
process of studying and teaching Russian as a foreign
language, allow drawing the conclusion that the
efficiency of assimilation of the considered units is
caused by knowledge of their structure and semantics,
by understanding the values, determined by them
Lodging resistant is a very important factor of limitation of the yield of barley. The yield of lodged crops may be decreased up to 50%. The quality of the yield also deteriorates which negatively affects brewery characteristics. The lodging resistance of a variety is determined genetically and depends on a plant height and weather conditions during dynamic vegetation. One of the main aims of breeding of the crop for lodging resistance is the selection of short-stem varieties. However, a thorough study of the basic material and determination of its adaptability to a particular soil and climatic zone and suitability of its usage as parental forms are needed. The article covers the plant height of collection varieties of winter barley in the central zone of Krasnodar region and determines the groups of the varieties based on this trait. The dynamic of plant height formation depending on the vegetative conditions during five years is studied. The examination of lodging resistance of winter barley revealed that there are many non-lodging forms of the crop. New local varieties and lines have short and strong culms. Also, some varieties from Western Europe and the USA show its good lodging resistance under these conditions

This 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
