The effect of seeds shapes and sizes to field survival, plant stand, harvesting amount and structure of calendula crude drug were under investigation. Biological feature of calendula is heterogeneous seeds formation, when the same inflorescence forms seeds of various shapes and sizes. The following seeds fractions according to their shapes and sizes were used for sowing: uncinate shaped, crescent shaped as well as unseparated, including, except uncinate and crescent seeds, ring-form and scaphoid shaped seeds. It was discovered that maximum indices of laboratory, field survival of calendula seeds and plant stand were in conjunction with uncinate shaped seeds. Maximum crude drug harvest was in conjunction with the sowing seeds of uncinate shape, varied from years from 2.11 to 2.40 t/h; minimum- at unseparated seeds sowing, varied from years from 1.83 to 2.05 t/h. Crude drug extreme efficiency was determined in 1-3 gatherings by inflorescence weight gain and its quantity increase on the same plant. According to the size of elements of crude drug harvesting structure (inflorescence quantity and mass of the same plant, the same inflorescence mass) the variant of uncinate shaped seeds sowing had advantages
In our country, great influence is given to the
production and consumption of agricultural animals'
meat with high consumer qualities. In this regard, the
livestock producers, particularly pigs, are to increase
production and improve product quality. Works on
using some natural mineral complexes - bentonite and
zeolites as a source of macro - and trace elements are
performed. The aim of the research is to study the
effects of bentonite feeding with free access on the
meat productivity and hygienic meat quality of young
pigs for fattening. Best effect on the slaughter indexes
of fattening gilts had bentonite feeding with free
access that resulted in significant superiority of the
animals in the experimental group over the control
counterparts on pre-slaughter live weight, slaughter
weight, chilled carcass weight, slaughter yield, carcass
length, the "muscle" eye area and the backgammon
weight. More favorable effect in the longest muscle on
the dry matter and protein synthesis was provided by
bentonite feeding with free access. Due to this, the
gilts of the experimental group were in significant
advance of their control counterparts in concentration
of dry matter and protein in meat. Along with this, the
longest muscle of young pigs on fattening in the
experimental group had the highest protein value, as
according to the protein-qualitative indicator the
animals of this group were in significant advance of
the control counterparts. Feeding bentonite clay with
free access had a strong detoxifying effect that is
against control counterparts of gilts in the experimental
group showed the significant reduce of lead, zinc and
cadmium concentrations in the meat
For further increasing pork production and to increase
its quality it is necessary to provide complete and
balanced feeding of young pigs for fattening. The
special place takes the issue of satisfying their
physiological needs in macro and micronutrients. The
most cost-effective step in these circumstances is using
bentonite clays as natural mineral supplements. The
aim of this work was to study the effect of the addition
of bentonite of Zamankulskaya field on the energy
growth, digestibility and the digestibility of nutrients
of the diet of young pigs. According to the results of
the survey, the best productive effect was when
ensuring free access to the bentonite, so that the young
pigs of the 3rd experimental group vs control group had
significant superiority according to gross and average
daily live weight gain and feed products. According to
the results of scientific and economic experience, it
was found that with free access to the bentonite best
economic and useful indicators were observed in the
animals of the 3rd experimental group against the
control analogs, as they had significant superiority in
terms of absolute live weight gain and feed
consumption per unit of production. During the
physiological exchange of experience the most
beneficial effect on the hydrolysis of complex organic
compounds had bentonite feeding with free access of
pigs. The result was a significant superiority of the
experimental animals over the control ones in
coefficients of digestibility of dry matter, organic
matter, crude protein, crude fat and NFE. To improve
the digestibility and absorption of nutrients in the diet
of young pigs it is advisable to feed them with
bentonite clay as natural mineral supplements with free
access
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
N0P0К0; 2-minimum dose of complete mineral fertilizer
N60P30К30; 3-average dose N90P60К60; 4-high dose N120-
160P90К60. Seeding rate is 5 million germinating seeds per
hectare. The objects of the research were seven winter soft
wheat cultivars of Krasnodar Agricultural Research Institute
selection. We studied winter wheat cultivars with different
combination of biological characteristics and predecessors.
This combination is contributed to the yield growing
from 4,26-5,82 t / ha up to 6,97-7,2 4,26-5,82 t / ha
with the payment of one kilogram of active fertilizer substance with the output of grain within 8,52-12,0kg
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 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

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 %
