In the article the effects of examinations on influence of a vascular necrosis on a survival of shanks of grapes of breed Saperavi inoculated on stock RхR 101-14 are introduced
The studies revealed that the application of spirits as a
strength agent of 91.0 - 96.6% in special wines
contained more vitamin-like substances than wine,
alcoholized with double-distilled water with 75%
alcohol concentration. The highest marks for tasting
wines were given to the options made with the use of
rectified grain origin alcohol as an agent of alcohol.
Application of double-distilled water wine leads to
accumulation of unnecessarily high undesirable
groups of compounds such as methanol and fusel oil,
thereby reducing the quality of the wine. Organoleptic
parameters were the best for selection of wines from
Anapa ZOSViV - Dionysus and Krasnostop EPA, as
well as - Cabernet Sauvignon. We can conclude that
for the production of high-quality red dessert wines
we need, along with the classic varieties, wider use of
new autochthonous varieties using alcohol agents of
rectified grain origin
In the article there were presented the results of the researches of the influence of different norms of consumption of the Nutrivant Plus water-soluble phosphorus-potassium fertilizer used for non-root additional fertilizing of Shardone grape shrubs, on accumulation of sugars in berry juice, crop productivity and quality of grape, growth processes of shrubs, quality of wine materials. The most effect is obtained at the norm of the preparation in 2 and
3kgha
This article discusses the results of the study to determine the impact of different primary tillage and herbicide against weeds in winter wheat agrocenosis. The task of the research was to determine the impact of primary tillage (moldboard plowing and surface treatment) factor A and herbicide (Lancelot) factor B on the agro-physical and agrochemical soil properties. It has been established that the content of productive moisture during the growing period of winter wheat in 0-100 cm of soil layer didn’t depend on the method of tillage. Introduction of herbicide Lancelot boosted the moisture reserves in soil compared to the control type, in the herbicide-free type the weeds absorb the large amounts of moisture. Surface soil treatment did not have negative effects on soil agro-physical properties and its structure in comparison with moldboard plowing. Number of agronomically valuable aggregates on moldboard plowing is 85.2 - 87.5%, on surface one is - 86.2 87.5%. Density of composition and waterproof aggregates under surface treatment didn’t defer to tillage. Accumulation of wet and dry mass by weeds regardless to the way of soil tillage declined to a minimum when introducing the herbicide Lancelot. The high yield of winter wheat was obtained on this type. Mathematical processing results have shown that due to factor A (main soil tillage) to moldboard plowing the average productivity is 57.5 kg/ha, on surface one is 56.0 kg/ha, i.e. the difference between treatments is 1.5 t/ha (with NSR05 on factor - 2.9 t/ha) is insignificant. To factor B (herbicides) on control the productivity is 54.5 kg/ha, introduction of Lancelot increased the productivity to 59.5 t/ha, i.e. the increase was 5.5 kg/ha at NSR05-by the factor B-2.9 t/ha, i.e. is significant. Thus, the present soil treatments had no effect on yield of winter wheat in ordinary black soil. The use of herbicide Lancelot has produced the harvest increase in 0.5 t/ha on average for 2 years
There were presented the results of the researches on study of regeneration properties of grape grafts of the Saperavi variety prepared from bushes which were treated with solutions of the “Vympel” preparation and mineral fertilizers of new generation – Nutrivant Plus and Kelik potassium silicon for vegetation period
three times. There was studied the influence of preparations on productivity volume from a bush and as well as main indexes of spear- and root-formation ability of grafts; there were determined the presence and degree of correlation connections between productivity from a bush and size characteristics of
spears in low zone, as well as the degree of graft maturing and hormone activity of wintering buds on them on the one hand and indexes of root-formation ability of grafts on other hand

In the leached black soils of the foothill zone of the
Kabardino-Balkarian Republic on the territory of
training experimental plant of FSBEI HE
Kabardino-Balkarian state agricultural university
named after V.M. Kokova we have studied the
effect of soil and climatic conditions of area of
cultivation and application of micro – macro
fertilizers, plant growth regulators and biological
products on the crops of lentils, their impact on the
efficiency and quality. It is proved that in general,
the natural conditions of the foothill zone are
favorable for cultivation and obtaining high yields
of major crops. The analysis of meteorological
conditions of the area (typical for the whole area)
shows that there are great reserves and
opportunities to obtain high and stable yields of
lentils grains. These morphological, genetic and
agrochemical parameters of leached chernozem
growing zones suggest the soil favorable to the
growth and development of lentils. On average,
during the years of studies, the number of plants on
which we had marked tubercles, on the example of
Rauza varieties in the background variant, was
63.7%; the use of the drug called Agropon C in
combination with sodium selenite increased by
15.2% the number of plants with root nodules.
Increasing the number of plants with root nodules
was accompanied with increasing the number and
weight of nodules per plant by 8.1 pc. and 10.1 mg.
respectively. The highest yield - 2.66 t/ha under
experimental conditions was obtained in the form
of joint use of the drug Agropon C and sodium
selenite with a seeding rate of 2.2 million viable
seeds per hectare, which is higher than the
reference version for this seeding rate by 0.46 t/ha
or 17.3%. The maximum value indicators of protein content in the seeds and collecting the
protein per unit area reached with the use of joint
application of Agropon C and sodium selenite,
where we achieved the seeding rate of 2.2 million
of germinating seeds per hectare and made up
29.6% and 787 kg/ha, respectively
The article presents the results of the studies on the
effect of the processing of grape variety Saperavi with
a growth regulator called Vimpel with water soluble
and foliar fertilizers of new generation - Nutrivant plus
and Kelik potassium silicon, both in pure form and in
a tank mixture. Processing of bushes was performed
three times: after flowering, growth phase of berries
(berry of a pea), the beginning of ripening berries. We
used Vimpel drug and foliar fertilizers such as
Nutrivant plus and Kelik potassium-silicon, both in
pure form and in conjunction with Vimpel; it led to a
significant increase in weight of the bunch, bush crop
and planting yields. The smallest yield increase was
provided by Vimpel. However, the combined use of
this drug on a background of Kelik silicon- potassium
foliar fertilizer and Nutrivant plus led to a greater
increase in yield from the bush than when used
fertilizers only. Processing of bushes by Vimpel in
combination with a foliar application of Kelik
potassium-silicon not only led to a significant increase
in crop yields from the bush and plantations, but in
two cases of the three it contributed to a significant
increase of the mass concentration of sugars in the
juice of berries. Using Vimpel, together with Nutrivant
plus foliar application for two years out of three
promoted maximize yields (23.4 and 18.4%) with a
decrease in sugar content, and in one year - an increase
in the harvest of 10.4%, with a significant increase in
mass sugar concentration (1.92 g / 100 cm3 or 9.2%).
Thus, the processing of Saperavi grapes with a growth
regulator called Vimpel and water soluble foliar
fertilizers of new generation - Nutrivant plus and
Kelik potassium and silicon is an effective method of
increasing the yield and quality of Saperavi grapes
The article brings the results of three-year studies of the
influence of the periods of sowing on productivity of
new varieties and lines of winter barley
In the soils of rice fields, eluvial gley processes
develop, which are manifested in redistribution of silty
particles along the profile, water-soluble humus,
mobile compounds of iron and phosphorus. Most
intensively, these processes are developed in meadowbog
soils, confined to closed depressions of the plains
plain. Meadow-black soils lying on elevated relief
elements have more favorable physical, physicochemical
and oxidation-reduction properties for
cultivating rice and accompanying crops in crop
rotation. The highest yield of rice is formed on high
checks and higher at 12,4 c/ha than on low ones
