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
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
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
stature (massiveness, the meat content, arizonia),
which were higher in males and females when fed with
mixed fodder with the introduction of ecoventura and
limestone in an amount of 1.0 and 3.5% respectively.
Introduction to feed composition of ecoventura and
limestone in an amount of 1.0 and 3.5%, respectively
had a positive impact on exterior indicators of rearing
ducks
The value of the initial material for selection for heterosis
is primarily defined by the combining ability in
respect to the main economically valuable characteristics.
Combining ability with respect to “grain productivity”
has been studied among fourteen selfpollinated
lines of maize of early ripening and three
testers in the system of hybrid combinations. We have
proved that weather conditions have an influence on
the variability of the estimates of the combining ability.
We have identified the new self-pollinated lines of
maize SP 165 and SP 175, which are characterized by
invariably high evaluations in the effects of GCA (gi)
in different years. The new self-pollinated line SP 167
has got high variants of SCA (δ2si). The new lines SP
161, SP 163, SP 167 and SP 174 have been characterized
by the variability of the evaluations in the effects
of GCA. They are related to the first or second rank in
respect of GCA, depending on the year of the conducted
evaluation. These are SP 163, SP 164, SP 170,
SP 171 and SP 173 that have differed by their variability
of the variants of SCA (from the low variants to
the high ones). The highly productive testcross hybrids:
Madonna M × SP 165 (4.88 t / ha), Madonna M
× SP 171 (4.85 t / ha), Madonna M × SP 167 (4.80 t /
ha), T 7M × SP 165 (4.78 t / ha) have been obtained
based on the self-pollinated lines having invariably
high figures of GCA and SCA

The obtained experimental data show that the incorporation of trace elements into the system of the sunflower crop has a positive impact on the mineral nutrition of plants, the number and quality of the crop. Foliar feeding of sunflower crops with micronutrients improves nutrition of plants with nitrogen, phosphorus and potassium, thus creating the preconditions for the formation of highly agrocenosis. The seed yield of sunflower increased by variants with application of micronutrients 1.2-3.5 t/ha or 4.4-12.9 percent. The greatest impact of treatment with boron and copper, exceeding the background option 3.1-3.5 t/ha or 11.5-12.9% respectively. The crop is least influenced by manganese and molybdenum. The examined elements positively influenced the structure of the sunflower crop. The greatest influence on the diameter of the basket, the number of seeds, weight of seeds in the basket, the weight of 1000 seeds was provided by the zinc and copper. Trace elements contributed to the improvement of quality indicators of sunflower. For husk content, the greatest positive effect was cobalt, zinc, manganese and copper, increasing the background option 10.1, 10.4, 10.5 and 10, and 6%, respectively, on the oil content of sunflower seeds had cobalt, copper and zinc. The oil content on these options amounted 55,0, with 55.1 and 55.2%, respectively, increasing this figure by 1.5 to 1.7 %. The acid number at variants with boron, manganese and zinc was the same with the background option and amounted to 1.8. The greatest influence on iodine number provided molybdenum, zinc and copper, which accounted for 170,5, 171,2 and 171,4, exceeding the background option 10.2 and 11.1
