The research is aimed at studying the compatibility of
different doses of ecoventura (TU 9283-199-
10514645-13) and limestone in the diets of rearing of
ducks of "Blagovarsky" cross and the impact on
productive performance. As a result of scientific and
economic experience obtained data on the dynamics of
live weight in groups of rearing ducks indicate that
ecomentors in combination with limestone have a
growth promoting effect and a positive effect on the
growth of ducklings. Best growth depending on dose
administration of ecoventura and limestone in feed
composition had a rearing ducks III (ecomentors
(1,0%) + limestone (3,0%) by weight of the feed) and
IV experimental groups (ecomentors (1,0%) +
limestone (3,5%) by weight of the feed). The results of
the study measurements (body length, keel length,
breast width, chest girth, chest depth) and indices

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
The article considers one of the types of water erosion
– illuvial process, the redistribution of dispersed
particles in the soil profile due to irrigation. The
proposed description of the process of moving silt
particles in the soil profile is based on the theory of
viscose-plastic continuum motion
Increasing the yield of crops is a global challenge posed by the scientists from all over the world. To achieve this goal, we use various methods such as: engineering, agro-technical, agronomic, chemical, physico-chemical and so on. We conducted a theoretical study, which showed that the use of physical and chemical methods of treating seed before sowing has a positive effect on the growth processes of seeds. One of such methods is an ozone treatment, which has established itself as a quality growth stimulator of agricultural plants. But despite numerous studies there is no clear description of the mechanism of ozone effects on seeds. In this article, based on our theoretical study, we have presented a material that allows revealing the positive effects of ozone exposure to the seed. To confirm these theoretical results, we have decided to conduct a pilot study. In connection with what, in this article we have included the materials containing information on laboratory equipment and methods of the experiment. We have also presented measuring equipment and methods of iodine-metric method for determining the concentration of ozone in the ozone-air mixture, exact conformance with calibration gas analyzer which will allow to obtain reliable data on the dose effects of ozone on the grain
After World War II, in 1946, our country understands
the problem - a terrible drought. To protect themselves
against such disasters in the future, on October 20th
,
1948, by the Council of Ministers of the USSR and the
Central Committee of the Central Committee of the
All-Union Communist Party of the Bolsheviks a
resolution "On the plan of shelterbelts, the introduction
of grass crop rotation, construction of ponds and
reservoirs to ensure high crop yields in the steppe and
forest-steppe regions of the European part of the USSR
" was adopted, later known as the "Great Plan for the
Transformation of Nature". During the years 1950-
1965 it was planned to create the next big state
protective forest strips from Saratov to Astrakhan on
both banks of the Volga River; - in the direction of
cities and towns: Penza - Ekaterinovka - Veshenskaya
- Kamensky, in watersheds of the rivers Khoper and
Medveditsa, Kalitva and Berezovaya; in the direction
of cities Kamyshin - Volgograd, in the watershed of
the rivers Volga and Ilovlya; in the direction of towns
Chapayevsk - Vladimirovka; in the direction of cities
Cherkessk - Elista - Volgograd; - in the direction of the
mountain Vishnevaya, Orenburg, Uralsk and the
Caspian Sea on the banks of the Ural River; in the
direction of cities: Voronezh - Rostov - on - Don; on
both banks of the Don River; on both banks of the
river Seversky Donets from the city of Belgorod to the
Don River. Strips were created in the steppe and forest
steppe areas. It was the first, in the history of
humankind, largest environmental program of impacts
on the climate of the huge territory, designed to protect
permanently fertile agricultural lands from harmful dry
winds, dust storms, lack of moisture and soil erosion.
We have studied the site of the State protective forest
strip "Cherkessk - Elista - Volgograd" located in the
"Kuban forest districts" of the Karachay-Cherkessia
Republic. In this area the analysis of taxation
indicators was made, the dynamics of change in the
stock of plantations connected with age was studied
In the present article the main research results of
investigation of the means of pre-milking and postmilking
treatment of cow udder and dugs are presented.
The treatment of cow udder dugs produces great effect
on the milk quality, the incidence level of mastitis of
cows in the herd, extension and pathogenic agents
transmission from sick to healthy animals; and also
udder treatment provides hygienic protection of udder
dugs. Tree concentrations of detergent of chloride
dioxide were tested. Whereof, dilution of detergent with
concentration of 90 mg/l chloride dioxide proved
effective disinfective effect in pre-milking treatment of
udder dugs. The developed medication for post-milking
treatment of cow udder dugs presented high preventive
efficiency against mastitis and provided longer hygienic
protection of cow udder dugs after milking

The study was conducted in a stationary multivariate experiment at the experimental station of Kuban State Agrarian University during eighteen years. The technology of growing winter wheat was improved by the optimization of norms of fertilizers and plant protection systems for different levels of soil fertility. Totally there were 48 technologies for growing winter wheat after and grain: corn, sunflower, sugar beet, where studied in the experiment. The best combination of high yield (77.2 t / ha) with high quality grain (nature - 789 g / l, the total vitreousness - 60%, -14.2% protein content, gluten content - 29.0%) was found under intense technology. The grain quality meets the requirements for the 2nd class. Similar productivity (yield - 76.4 t / ha, the total vitreousness - 55% protein content - 13.4% gluten content - 27.2%) was obtained in and when grown for its resource-saving technology also. All kinds of technologies for growing winter wheat studied in the experiment were profitable, but resource-saving technology was the most efficient. Net income per hectare under this technology was 31,745 rubles, and a cost of 1 quintal of grain - 284 rubles
The article contains the results the study of the mechanical composition of clusters and biochemical characteristics of the red wine grape varieties of Cabernet Sauvignon, Cabernet Franc and Merlot (regionalized), Cabernet Carbon, Cabernet Kortis and Verdot black (introduced). In terms of the structure of the cluster of the variety they can be divided into three groups: Cabernet Kortis and Cabernet Sauvignon (16,6-16,8), Cabernet Carbon, Cabernet Franc and Verdot Black (17,5-17,9), Merlot (19.9 ). In terms of addition of the variety they can be divided into four groups: Cabernet Franc (6.3), Cabernet Sauvignon and Merlot (4.9-5.0), Cabernet Carbon (4.3), Verdot Black and Cabernet Kortis (3, 7-3,4). Structural parameters of the clusters of the varieties we have studied were ranged from 5.1 to 5.6, and the berry from 64.3 to 74. The yield of the wort from Cabernet Sauvignon, Cabernet Franc and Merlot is equal to 75,1-77,7% from Cabernet Carbon, Cabernet Kortis and Verdot Black - 70,5-72%. Mass concentration of sugars in the studied varieties was in the range of 22,3-26 g / 100 cm3, titrated acids - 0,47-0,77 g / 100 cm3, active acidity - 3.1-3.8. The ratio of fructose to glucose was: Verdot Black - 1.2, Cabernet Sauvignon and Cabernet Carbon - 1.5, Cabernet Kortis - 1.8, Kabernet Franc - 2.8, Merlot - 3.2. Most ranged organic acid in all varieties – wine acide. Relation of the content of tartaric and wine acids in varieties amounted: Cabernet Kortis 7: 1, Cabernet Karbon 6: 1, Cabernet Franc 2.8: 1, Cabernet Sauvignon and Merlot 2: 1, Verdot Black 1,4-1.
