Experimental studies were carried out on the breeding
farms of "Russian pork" in Millerovo district of the
Rostov region on purebred and crossbred animals
derived from crosses of pigs and the Don steppe types
of meat, breeds of Landrace and Pietrain. The Don
type of meat was used in the experiments as a control.
When crossing, the DM-1 pigs were used as the parent
form, and CT as a father to give twin breed hybrids
DM-1 x ST. The recent delivery of boars of Landrace
and Pietrain breeds allowed to receive twin breed
hybrids of genotypes of CT × L and DM-1 × P
The article highlights the issues of grape plants resistance
to low temperatures; it is an urgent problem for
all wine-growing regions of the world, located in the
zone of risky agriculture. Losses caused by frost, indicate
long-standing necessity of perfection of assortment
in terms of enhancing its hardiness by enriching
more resistant genotypes obtained both through the
introduction or naturalization, as well as from the
crossing of indigenous with interspecies hybrids. Methodology for evaluating frost resistance properties
of the material served as a preparation for the originality
of his research and experimental evaluation of the
unique divisibility properties of the aim. Thus, we initially
conducted hardening of matured cuttings at positive
temperature plus 8 plus 4 ° C for 14 days (I
quenching phase) and a negative temperature minus 5 °
C-minus 7 ° C for 9 days and minus 10 ° C-1 day (II
hardening phase). Then the cuttings we frozen in the
temperature range from minus 16 ° C to the next steps
of consistent freezing (minus 16 ° C - 2 days; minus 18
° C - 2 days; minus 20 ° C - 2 days; minus 22 ° C –
1day, minus 24 ° C - 1 day, minus 26 ° C - 1 day, minus
28 ° C - 1 day and minus 30 ° C - 8 hours). After
freezing of cuttings of each variety, the sample was
placed on the 3 days in the refrigerator at the temperature
of + 2 ° C to their gradual thawing. Cuttings were
grown at room temperature on water. As a result, obtained
by the accounting: the lowest frost-resistance
among the studied forms of parental Crimean origins
was found in grades of Shabash, Soldayya and Solnechnodolinsky;
the varieties of Dzevat kara, Kokur
bely, Kokur cherny, Misket, Misgyuli kara, Sari Pandas
were set as a weak level (-20 °C); Aybatly, Kefesiya,
Kok pandas and Ekim kara have average level up
to -22 °C; the highest frost-resistance - 24 °C – was
shown by Khersonessky and Kapselsky. Also, we have
identified synthetic frost-resistant F1-population and
plus-transgressive selection form
Excess body weight is a serious problem, involving a
set of diseases presently. For this reason, taking into
account demands of science there was a development
of production of food with the lowered energy value
for the people having first of all obesity that led to
production of substitutes. Even more often producers
resort to use of nutritional supplements, which
generally receive in synthetic way. In this article, we
analyzed multiple references and summarized the
material regarding beet fibers. As a result of numerous
researches it has been proved that food fibers make
favorable impact both on the separate systems of a
human body, and on all organism. The use of the
minor products of processing of the plant raw material
is also critical; they allow improving the preventive
properties of products and enriching them with dietary
fibers, protein, and mineral elements and also
development of food development of curative and
preventive action. Citri-Fi food fibers which are
received from dried-up orange pulp are well-known,
they can keep a large amount of water throughout
technological process. They exert positive impact on
structure of fat that gives the chance to create a
product with the lowered content of fat
EFFICIENCY OF CULTIVATION OF DIFFERENT WINTER WHEAT CULTIVARS IN THE CONDITIONS OF THE WEST CAUCASUS
The influence of the crop rotation type, predecessor and different doses of mineral fertilizers on the yield of two winter wheat cultivars (Lira and Krasnodar 99) was investigated. The investigations were carried out in the North-Kuban Agricultural Experiment Station in two five-crops: grain tillage and grain - grass tillage rotation of prolonged stationary experience. The soil is the black soil, low in humus, powerful, with humus content, depending on the power of nutrition backgrounds in the arable (0-30sm) soil layer is 3,95-4,00%, of mineral nitrogen is 5,9-8,3 mg / kg of soil, of exchangeable potassium is 330-360 mg / kg of soil. It was found that the maximum value of the winter wheat crop structure elements is noticed in the fertilizer systems with complete mineral fertilizer, and the minimum value - with PK and NK. Winter wheat yield depends on the crop rotation of 8-15%; from its predecessor - 15-18% and 27-31% of the fertilizer. Grain quality was generally determined by the dose of fertilizer. High and higher doses of fertilizers contributed to the protein content from 11.7 to 12.3% and fibrin content - 23,5-24,0%. A strong correlation between yield and agronomic methods was determined
The article presents the results of the study on the magnesium mode of leached chernozem of Western Ciscaucasia at three rotation of grain-grass-tilled crop rotation. Magnesium in the soil is represented mainly by non-exchangeable form, the number of which is estimated at 90,18 and 91,29 % of gross reserves. Exchange forms of magnesium are 8,68 and 7,71 % respectively in arable and the subsurface layer. The share of water-soluble and organic forms account for less than 1 % - of 0.62 and 0.68 and 0.46 and 0.38% respectively. For three rotation 11-full rotation of gross stocks of magnesium in the soil in which crops were grown without fertilizers has decreased by 0.02 % (200 mg/kg), with fertilizers of 0.03 and 0.02 % (300 and 200 mg/kg). Intense magnesium has been leached from the topsoil. There was a change of the soil content of the forms of magnesium. In the rotation without fertilizer, the share of non-exchangeable magnesium in the General Fund item increased from baseline by 0.27 % in arable and 0.11% of the subsurface layer of soil that the absolute content decreased. The amount of water-soluble, exchangeable and organic magnesium of the soil decreased. Reducing the amount of water-soluble (0.05 and 0.06 %) and metabolic (0.18 and 0.02 %) of magnesium was due to its consumption of the plants. The proportion of magnesium organic part of the soil is reduced as a result of steadily declining yields, and, therefore, the amount of organic residues. In crop rotation, use of mineral fertilizers we have observed different behavior of magnesium compounds in the soil. The number of non-exchangeable magnesium decreased from baseline by 0.13 % in arable and 0,58 % of the subsurface layer of soil. The content of the exchange of magnesium increased respectively 0.43 and 0.41 %, water soluble - 0.13 and 0.10 %, and the organic part of the soil - 0.02 and 0.02 %
This article presents the experimental material obtained
from long-term stationary experiment of GNU
"Severokubanskaya agricultural experimental station"
in P.P. Lukyanenko Krasnodar Agricultural Research
Institute. Stationary experience was founded in 1978. It
had two ten-course crop rotations and combined graingrass
tilled. The ordinary black soil, low-humic, heavy
loamy in mechanical composition. The capacity of humus
horizon is 113-116 cm with a total content of humus
on the date of the experience beginning is 3.88%.
Arable (0-30cm) layer was characterized by the following
parameters: total nitrogen content - 0.22-0.24, mineral
-10,0-10,5mg / kg of soil, total phosphorus-0,16-
0,19%, labile phosphorus - 12,2-12,9mg / kg soil total
potassium -1,7-2,0%, exchange potassium- 386mg / kg
soil. The degree of saturation of bases is 80-90%. The
amount of absorbed bases is 30-40 m ekvg/ 100 g of
soil. The reaction of the soil solution is weakly alkaline
(PH water 8.0-8.2). The predecessor is winter wheat.
General Agrotechnics is recommended for a given soil
and climate of region. Solid mineral fertilizer were applied
as mineral fertilizers in combination with organic
fertilizer in the form of half-decomposed cattle manure. According to agro-climatic zonation the northern zone
of the Krasnodar region, where the research was conducted,
is related to the zone of insufficient watering
with hydrothermal coefficient 0.7-0.9 with an annual
rainfall of 350.5 to 899.8 mm. During the autumn and
winter period, which determines the accumulation of
water in the soil, from 150.3 to 426.8 mm of rain falls
or 30,4-68,9% of the annual amount. During the vegetation
of sugar beet from germination to harvest -112,0-
588,9mm of rain falls, with an average daily temperature
of the air 16,5-20,000С, including the period of the
greatest growth of roots and accumulation of sugar
from 3.2 to 557.1 of rain falls with air temperature
19,5-28,800С. Hydrothermal index is 0,01-2,83. During
the years of the research 19% of years have been characterized
as unfavorable (hydrothermal index 0.67),
44% of years as moderate on moisture supply and temperature
conditions (hydrothermal index 0.99) and 37%
of years as favorable (hydrothermal index 1.05). The
generalization of the research results obtained by us in
the long-term stationary experiment, allowed us to estimate
the impact of different standards and systems of
fertilizer on the productivity of sugar beet and sugar
content in the roots. On average, during the years of
research, the root harvest under the influence of fertilizer
amounted to 36,7-45,6 t / ha per unit area with the
addition to the control variant, that isn’t manurable,
amounted from 6.6 to 15.5 t / ha. The highest yield of
root is 43,0-45,6 t / ha which was obtained with systems
of fertilizer with complete mineral nutrition

The article presents results of the six-year study of the
effect of stocks Riparia × Rupestris 101-14 and Berlandieri
× Riparia Kober 5BB on yield, quality of
grapes and Aligote wine in the central zone of the
Krasnodar region. Effect of stock on scion strongly
depends on the annual weather conditions. In a given
year, there is a stock better adapted to the weather
conditions. Stocks of Riparia × Rupestris 101-14 increase
winter hardiness, and the stock Berlandieri ×
Riparia Kober 5BB - drought-resistant varieties of
Aligote. On average, during six years the stock has not
been resulted in significant differences between the
percentages of developed into shoots buds and fertile
shoots shown in the coefficients of fruiting and fruitbearing
shoots of Aligote. Among all the influencing
factors, the degree of influence of stocks on the percentage
of buds have evolved to 16,4 %, by the percentage
of productive shoots 19,8 %, a factor of the
fruiting shoots and fruitfulness of 3,9 % and 2,7 %,
respectively. Some differences in forming of generative
organs of wintering buds along the fruiting twig
under the influence of stocks do not lead to the significant
difference in biological terms of fruiting varieties
in the whole piece. On average, six years of significant
differences in the influence of rootstocks on the number
of berries in bunches, hundred berries weight, an
average weight of bunches and yield is not defined -
the degree of influence of stocks on mentioned indicators
is 0,1-9,7 %. A significant impact of stocks on the
dynamics of sugar accumulation in berries has not
been discovered. The degree of influence of stocks
onto the final sugar content and acidity of berries is
2.9 and 1.0%, respectively. The wine produced from
Aligote berries on a stock Riparia × Rupestris 101-14
has the better tasting score than on the stock Berlandieri
× Riparia Kober 5BB (7.9 and 7.8 points, respect
vely). The main influence on fruiting of the variety
Aligote was provided by the conditions of the current
and previous vegetation. Within the conditions of the
central zone of the Krasnodar region the cultivating of
the variety of Aligote is reasonable for both studied
stocks
Petrovsky garden was founded in 1703 and is the most
important historical object of landscape architecture in
Petrozavodsk. Tikhon Balandin made a description and
drawing of Petrovsky garden at the beginning of the
19th century. He completed his work by studying and
measuring the fragments of the earthen fortress, blast
furnace and the location of the destroyed palace, pond
and birch garden. On the basis of the historical
documents, we created a 3D model of Petrovsky
garden using of modern computer-aided design. Threedimensional
model of the garden allows viewing the
object from different angles, gives an idea about
structure and compositions of the garden on a new
visual level. Some examples of visualization garden
fragments were presented at the article. Now the
garden doesn’t have its original structure. The
historical garden layout and 3D model of object can be
used for reconstruction of Petrovsky garden
The influence on the predecessor, on the time of sowing
and various mineral nutrition levels, on the productivity of
seven cultivars of winter soft wheat of Krasnodar Agricultural
Research Institute selection was investigated. On the
basis of the obtained experimental data and production
audit it was found that all studied cultivars under the total
complex of cultivation technological methods are able to
form the yield of 6-7 t / ha with the payment of one kg of
active ingredient of fertilizer by the grain within 6.50-9.86,
and 8.56- 10.71 kg. Soil was ordinary chernozem with a
low humus content powerful humus content, depending on
the power of backgrounds in the arable (0-30sm) soil layer
is 3,95-4,00%, of mineral nitrogen is 5,9-8,3 mg / kg of
soil, mobile phosphorus is 22,4 - 26,6 mg / kg of soil, of
exchangeable potassium is 330-360 mg / kg of soil. Predecessors
are winter wheat, sunflower, white mustard cultivated
on seeds. The main tillage is resource-saving with
the mulching of 0-10 cm layer. Studied sowing terms are
the 20th of September, the 1st and 10th of October. The
backgrounds of mineral nutrition: 1-without fertilizer
