Currently in the South of Russia, the most acute problem of accumulation and preservation of productive moisture in arable layer of soil. This fact has a decisive influence on the yield of agricultural crops. The need to study the dynamics of accumulation of moisture of the treated soil due to the fact that at the first stage of development plants are very sensitive to moisture content in the rooting zone of the soil. Practically the regulation of the moisture content of the processed layer may correct the influence of soil tillage aggregates with different types of working bodies. The work was performed in FSRI of the «ASC «Donskoy» (Zernograd, Rostov area), in the conditions of stationary experience (4,3 ha), 2013-2015, where explores various technologies of soil treatment, including no treatment. To obtain comparable results the same selected set (rotation) of crops (winter wheat, spring barley, pea, vapor). As a result of researches it is established that on steam background (76,1-46,2 mm) content of productive moisture is more than two times higher than on other backgrounds (of 30,6-46,2 mm). This allows us to talk about the effectiveness of the fallow field from the point of view of accumulation of moisture. The analysis of statistical data allows making a conclusion about the impact of crops on the dynamics of productive moisture. On the other hand, the rating statistics of the received data with backgrounds treated with different technologies did not allow to find significant advantages to any of them, as the area under the curve ROС analysis does not exceed the value of 0,6. Therefore, the studied backgrounds in the period of the research have equal influence on the moisture content of the treated soil layer

Long-term storage of fruits can be achieved by means
of decreasing microbial contamination of their surface
as a result of fruits pre-treatment by biopreparations
before dispatching for storage. In the current study
patterns of influence of fruits pre-treatment with the
“Ekstrasol” biopreparation in a number of
concentrations of bioagent on the microbial
contamination of their surface during storage are
revealed. The “Ekstrasol” preparation is a biofungicide,
containing the Ch-13 strain of Bacillus subtilis bacteria
and their metabolites. As research objects there were
chosen apples of a zoned in the Krasnodar region
variety called Idared and pears of a zoned in the
Krasnodar region variety called Conference, harvested
in 2016. The apples and the pears were stored over a
period of 6 months in the low temperature conditions.
Samples were withdrawn every month over the period
of storing. The species composition and quantity of the
most prevalent microorganisms, potentially causing the
spoilage of apples and pears during storing, were
identified. The optimal concentration of the bioagent,
which provides the maximal decreasing of microbial
contamination of fruits’ (apples and pears) surface, is
established – 106
CFU/g, dosage of solution – 1 ml per 100 g of fruit
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
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
This article discusses some elements of the Brigade cultivating winter wheat varieties using different doses of fertilizers (N50P50K120 and N100P100K240) in four tillage options (plowing, chisel loosening, disc chopping and zero treatment). The experiment was conducted in a multifactorial stationary conditions. The considered agrotechnical techniques have led to a change in the density, hardness and structural composition of the soil. The most optimal values of these parameters have been obtained by using plowing and chiseling
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
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

There were cited the results of researches for 2010-2012 obtained in the stationary experiment of the chair of general and irrigated land management of Kuban State Agrarian University on the study of influence of the system of main soil processing under soya beans on the dynamics of main agrophysical indexes of leached black soil: on density of composition, solidity, general porosity, coefficient of structural properties in the article. There was stated that in the beginning of vegetation on the background of direct sowing of soya beans, the soil layer in 0-30 cm was characterized by values of density and solidity and in the result of it we observed the weak development of the root system. The worsening of air regime led to the decrease of symbiotic nitrogen fixation, it negatively affected on the growth and development of a cultivar. Agrophysical indexes brought nearer to optimal on variants with disposal tip on 20-22 cm and disk-shaped hulling on 8-10 cm. The worsening of investigated agrophysical soil indexes has been happened since the phase of florescence – soya bean formation till the harvesting. But the variant with disposal tip where we observed the high content of agronomically valuable fraction at the coefficient of structural property 2,42 was the closest to optimal ones. The minimization of soil treatment and especially the denial from its implementation significantly made worse the main agrophysical indexes of soil on variants with direct sowing to critical values for soya beans
