In order to find compounds that increase sugar beet resistance to the adverse effects of herbicides, a series of naphthalenesulfonamides derivatives have been synthesized. The protective effect of new compounds for the herbicide mixture Betanal, Lontrel and Super Zeleke was studied in field conditions. The effect of pyridylhydrazones on the synthesis of photosynthetic pigments in leaves was investigated. Substances with a high protective effect were found
The purpose of the study was to examine a century of
experience of growing of forest cultures of the
Siberian stone pine in forest conditions in the region of
the Middle Volga. To achieve these objectives, we
have investigated old growth culture of Siberian stone
pine in the conditions of fresh oak forests in the
territory of Rootka forestry of the Mari El Republic.
Culture of Siberian stone pine was planted after
continuous tillage. The distance between rows was 2,5
m, step landing – 1,0 m. The site was divided into five
options, depending on variations in the width of
planting strip (I-48 m, II-44 m, in III-40 m, IV - 36 m,
V - 32 m). The studies have shown that the Siberian
stone pine trees, regardless of the variant, are
characterized by good clean ability from twigs, which increases with decreasing of the width of the curtain. It
can be noted that in the 100-year-old age, the average
height of trees reaches of 28,7 m, an average diameter
of 49,8 cm. Stock of forest reaches 795,3 m3
/ha. Best
annual increase is observed in growing cultures of
cedar in the wings with a width of 40 m and is 7,95-of
7,93 m3
/ha. Based оn the research, we have concluded
that Siberian stone pine should be recommended for
introduction into the zone of coniferous-broadleaved
forests of the Middle Volga region. When creating
crops, it is necessary to use larger seedlings and plant
density is not more than 1,0 thousand pieces/ha, and
the width of the planting strip shall be not less than
40,0 m.
Intensification of agriculture during the twentieth
century was accompanied by an increase in
international trade, resulting in the resettlement of
many species across continents. As a result of these
processes, many adventives species have become
economically significant and dangerous plants in agro
and urban biosensors. One such plant is Ambrosia
artemisiifolia L., imported from North America to
Russia. The use of chemical means of suppression of
A. artemisiifolia L. often does not give positive results
in agrocenoses, because of its biomorphological
features. In urban areas, within the boundaries of
sanitary zones, the use of chemicals is prohibited.
Therefore, the most promising direction in the
suppression of ragweed ambrosia is the ecologies
method. The article discusses the possibility of using
an ambrosia leaf beetle in the feeding of ragweed in
the territory of Russia
An experiment has been carried out on the effect of
germination of seeds with perlite on the improvement
of the growth force of rye Vyatka-2. The purpose of
the experiment was to study the effect of perlite on
the growth force of seeds under the conditions of
additional fertilizers and changing the volume water
during irrigation. The task of the work was to
determinate the growth force of seeds with perlite.
The growth force of the seeds was determined after
10 days in sprouted seeds in five samples in glass
vessels with three different moisture conditions. It
was proved that germination of seeds with perlite
increased the seed growth force up to 28% in
comparison with seeds grown in sand (a control
sample). The result also depended on decreasing of
humidity rate up to 30-40%
The proposed agro technology for the cultivation of
soft winter wheat contributes to the reproduction of
fertility of leached Chernozem of the Western
Ciscaucasia. As a result of application of fertilizers in
the arable layer of soil hydrolytic acidity decreased by
21.8%, humus content increased by 10.3%, mobile
phosphorus - by 54.8%, mineral nitrogen by 10.3%
and potassium - by 9.6% compared to the control.
Studied agricultural technology allowed to increase the
yield of winter wheat to 81.8 kg/ha and protein to 15.3
per cent, of gluten, to 27.8%. We have noticed
exceeded concentration of mobile phosphorus in the
upper soil horizon (1.5 MРС) in the cultivation of
wheat after alfalfa, which contributed to reduced grain
yield. Under conditions of prolonged application of
fertilizers and pesticides reduced the content of mobile
forms of trace elements - copper and zinc. The content
of mobile forms of Mn, Cu, Zn, Cr, Ni, Co, Pb and Cd
below the limit values of environmental and
Toxicological regulations clayey and loamy soils for
agricultural purposes. The trend of accumulation of
cadmium in the green mass of plants (~ 1.2 MPC) and
winter wheat grain up to 1.5 MPC for baby food
The influence of different agricultural technologies on
the yield of winter barley variety ‘Gordei’ was studied.
Economic evaluation was given to the researched
factors. The studies were carried out at the
experimental station of Kuban State Agrarian
University in the conditions of polyfactorial long-term
soil monitoring. The soil is represented by strongly
leached, light-clay black humus with an average
thickness of the humus horizon - 150 cm. It was found
that with the change of technology (fertilizer, tillage,
sowing method, means of protection) winter barley
yields increases to 50% in comparison with the
control. According to the analysis of bioenergetic and
economic evaluation it makes sense to use the variants
022, 111 and 222 at plowing, where the maximum net
efficiency ratio and net income are noticed
The researches on the mustard protein-containing fodder concentrate "Gorlinka" use were carried out during 2015-2016 in the laboratories of Volgograd state agrarian university, as well as at LLC "Donagrogaz" in the Frolovsky district of the Volgograd region. During the research, the authors studied the new high protein fodder additive influence on the digestibility and feeds absorbency, as well as on the blood morphological and biochemical parameters. During the research, it was established that the used fodder additive has a positive influence on the dynamics of the digestibility coefficients and the nitrogen balance. During the physiological experiment, all the experimental cows had a positive nitrogen balance, in the control group it was 9.8 g (the lowest value), in the second group, it was 12.6 g, and in the first one, it was 12.0. When determining the experimental animals’ blood biochemical and morphological parameters the content of the studied components corresponds to the physiological norms. The average daily milk yield for the analogues from the 1st test group was higher as compared to the control, by 1.01 kg, or 5.1%. The mean daily milk yield of the control group was also lower than for the cows of the 2nd test group by 1.45 kg, or 7.4%
The researches were carried out with the support of the Federal state budget establishment "The development assistance fund of small forms enterprises in scientific-technical sphere" (Fund for the innovation promotion), contract number 0019671. The fodder additive «Nutovit» in growing chickens feeding application enriched mixed fodder for farm poultry with protein and especially with the amino acid such as lysine. Scientific-economic experiment was carried out at the poultry-farm enterprise of the Volgograd region in 2015-2016. 4 growing chicken groups with 54 heads in each group were selected for the experiment. The growing chickens were selected according to the cross, age, living body weight, health status. The difference in experimental poultries feeding was that in the experimental groups the sunflower oil cake in the feed mixture was replaced by fodder additive "Nutovit". It was established, that the essential amino acids availability and the saturation of fodder additives with vitamins influence positively on: young chickens live weight and average daily growth, the live weight to 120-days age in the second experimental group amounted to 1657 g, and average daily growth was to 12.46 g, which is higher compared to the control group by 4.48 % at 100% poultry livability; blood morphological and biochemical composition: formed elements of blood, namely erythrocytes, in the experimental groups young chickens blood were more in 0.02 to 0.05×1012/l compared with the control one. The researches established that blood leukocytes reduction in growing chickens of the experimental group was little, in 0.04, 0.09, 0.08 ×109 l. Calcium content in growing chickens blood in the control group was 2.6 mmol/L. The experimental group surpassed the control on 0.14-0.21 mmol/L. The phosphorus content in chickens blood in the experimental groups exceeded the control one by 0.08-0.24 mmol/l. In addition, the feeding cost reduction was established due to the fodder additive "Nutovit" use
This article presents the studying results of new premixes of domestic production using efficiency based on processed products, in particular - oil cakes. The research was carried out in the conditions of the second-order pedigree reproductor in LLC "Svetly" in the Svetloyarsky district of the Volgograd region in the period from 2015 to 2017. During the scientific and economic experience, the authors revealed the new fodder additives positive influence on the laying hens’ egg productivity, on the eggs morphological and incubation rates and on the got young birds. The use of premixes in layer diet, which included the fodder concentrate from the plant raw material "Sarepta" and Camelina seed oil cake, contributed to the increase in the hens laying capacity, in general, the group received in 249 and 310 pieces more than in the control one. The egg average weight from the chickens of the control group was 60.89 g; from the first experimental it was 61.33 g; from the second experimental it was 61.39 g, which was higher than in the control one, respectively, by 0.44 g and 0.50 g. While the hatching eggs morphological indices analysis, it was revealed that all parameters are within the permissible limits of the physiological norm. Fertilization of eggs in the control group was at the level of 89.33%, which is lower than in the experimental groups. As a whole, the eggs' production in groups was 20.00% in the control, 17.33% in the 1st group, and 16.00% in the 2nd test group
In the article, based on factual material, we reveal the
policy of tsarist Russia in Chechnya at the turn of the
1840-1850-ies. The article points out that in 1836,
Chechnya was not included in the national liberation
movement of highlanders of the North-Eastern
Caucasus. In early 1840, Shamil was elected the
Imam of Chechnya and the Imam of Dagestan and
Chechnya. The same year there was a General revolt
in Chechnya. Since that time, the center of the
national liberation movement in the North-East
Caucasus was moving to Chechnya. The article noted
that for the conquest of the Chechen population by
the king's command despite military means there
were made engineering, economic and ideological
measures. In the end, these measures and the
teachings of Kunta-Haji, which began to spread in
the same period of time, influenced the political
situation in Chechnya and the minds of the Chechens.
And all this, taken together, led to the fact that since
the early 50-ies of the 19th century some groups of
the society of Chechnya began to show a tendency
towards reconciliation with Russia. In the studied
time there was a change of tactics of the king's army
in Chechnya. The Royal army was moving from
trench warfare to the method of the marginalization
of Chechens further and further into the mountains,
through the construction of forest rides, and
consolidated in the captured territory a system of
military forts and Cossack villages. In 1850 the
Royal army began to implement a plan of invasion of
Chechnya which was Dagestan barns. This
undermined the economic base of the Imamate
heavily. Since the beginning of the 1850-ies and up
until 1859, the center of gravity of the Caucasian war
was transferred to Chechnya. There would be major
events that would create the fate of the Imamate.
Thus, the article characterizes the economic and
propaganda policy of tsarism and its importance in
the conquest of Chechnya; we have also highlighted
the military actions against the mountaineers,
explored the tactics and the strategy of the king's
army in Chechnya
