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 article scientifically substantiates and
experimentally confirms the high efficiency of the
nano biological feed supplement "NaBiKat" in diets of
broiler chickens of the "Cobb-500" cross. The
supplement is a new complex with a mixture of rice
germ films, green tea gallocatechin in chelated form,
and forty-nine trace elements in chelated form,
including biosoluble form of silicon. The main
function of silicon is to be involved in a variety of
intermediate exchange reactions as a catalyst and to
ensure normal flow of vital mechanisms as a coupler
helping to combine cellular molecules into a whole
functioning structure. Silicon begins to act on the body
when getting into the lumen of the gastrointestinal
tract with the feed. It activates the enzyme system of
the body and in ionic form is absorbed by kind of
ordinary diffusion along almost the entire small and
large intestine beginning from the jejunum. The
supplement studied has been proved to improve the
morphological structure and biochemical properties of
blood, to enhance metabolism, redox processes, and
the level of natural resistance. The broilers fed the
supplement "NaBiKat" in the experimental groups
have been found to have a higher concentration of
macro- and micronutrients in blood. The nano
biological silicon-containing supplement as a
compound of in the composition of feed for chickens
had a positive effect on their growth and development
Soil profiles were made in intensive apple orchard in the agricultural enterprises in Lipetsk and Tambov regions in 2015. Drip irrigation in year rates of 500-550 m3 was carried out since 2010. During the research we determined the soil density, the solid phase density, aggregate composition, particle size distribution, the content of hydrolyzable nitrogen and humus by conventional methods. As a result of drip irrigation can increase dust-like fraction in dark gray forest soil, whereas in chernozems this index did not change significantly. In the black earth soil was noted the process of increasing the proportion of mud fraction due to mineral part chernozem destruction. In both soil types was increased sand content. It was found that drip irrigation improves some of the soil water-physical properties, such as a soil structure coefficient and the content of agronomical valuable aggregates in a layer of 20-40 cm. There was also noted that with increasing soil depth was reduced humus and hydrolyzable nitrogen content. In aggregate analysis, it was found that dark-gray forest soil the amount of water-stable aggregates increased, while meadow chernozem leached soil decreased. Data of the aggregate analysis revealed that in the dark-gray forest soil the amount of water-stable aggregates increased as a result of drip irrigation, while in meadow chernozem leached soil decreased. It recommends by drip irrigation application permanent monitoring of the soil humus content
The article reviews the results of the study of the influence of treatment of Saperavi grapes with the growth regulators (Biodux and Avibif) on the quality of grape must and wine in the Anapо-Taman zone of the Krasnodar region
This article presents the results of the impact of
"Gorlinka" mustard protein-containing feed
concentrate in the feeding of broiler chicken of the
cross of "Cobb-500" on their performance and
nutrient digestibility of the feed. The studies were
conducted in the conditions of Krasnodonskaya
Poultry farm in the Ilovlinskiy district of the
Volgograd region. Full or partial replacement of
sunflower meal with "Gorlinka" mustard proteincontaining
feed concentrate in the feed mixture for
the experimental broiler chickens contributes to the
increase of the coefficients of digestibility of nutrients
compared to the birds in the control group. The use of "Gorlinka" mustard protein-containing feed
concentrate in the composition of feed for broiler
chickens has contributed to higher coefficients of
digestibility of nutrients: dry matter – 0.51-1,37%,
organic matter – 0.6-1,99 %, crude protein by 0.8-
2,24 %, crude fiber – 0,34-1,65 %; crude fat – 0.94-
2,29%, compared to the birds in the control group.
Nitrogen balance was positive in all groups; the use of
nitrogen from the accepted experimental broiler
chickens was higher in the experimental groups than
in the control by 2.89-of 7.93 %. The use of nitrogen
from digested nitrogen was higher in the experimental
groups in comparison with the analogues from the
control group by 2.65-of 7.97 %. The use of calcium
and phosphorus by poultry was also higher in the
experimental groups
Nowadays, domestic pig production is dynamically
changing in technological and selection terms and is
one of the most effective sectors. In the current
conditions of pig breeding in intensive technology, the
requirements to the level and direction of pig
production, the rational use of genetic resources are
increasing. The development of effective methods for
the production of pork on the basis of the wide use of
highly productive breeds and types of both imported
and domestic selection allows to obtain the maximum
possible productivity of animals, to produce pork of
good quality, to reduce the cost of production and to
fully realize the genetic potential of animals. Genetic
and selection techniques have significantly changed
the physiological, morphological and productive
capabilities of modern animals. In connection with
this, the actual for the pig industry is the identification
of opportunities to increase the duration of the use of
pigs, and the inclusion of new indicators in breeding
work when creating specialized maternal lines. The
research was carried out on the electronic database
(KP ACC, OOO "Selikom", Ryazan), the breeding
center "Lozovoye" ZAO "Plemzavod-Yubileyniy" of
the Tyumen region. The center is engaged in
thoroughbred breeding and improvement of four pigs:
large white, landrace, pietren, duroc
The contents of lead in soils are primarily determined by regional factors: the composition of parent rocks, relief, climate, vegetation. In recent years, these factors have increased the anthropogenic source of element. In order to assess its impact, requires knowledge of the natural, i.e., background lead levels, the so-called reference points, which can later be used to monitor changes occurring in the soil. Under background refers to the content of the element in soils at a great distance from the areas of receipt of contamination. Background content of lead in each type of soil depends mainly on composition of parent rocks. The correlation coefficient between the content of lead in parent rocks and soils, with the background contents is equal to 0,86±0,17 at p=0,95. For each soil type there are low variations in lead content due to the composition of parent rocks. Lead concentrations in the soils increased at the expense of its receipt from the atmosphere, irrigation water, drainage during mining, as a result of agricultural use, lead containing chemicals. Comparing the obtained results with existing currently permissible concentrations (APC, MPC) it is necessary to note that the lead content in leached chernozem soil after three rotations of the rotation may not cause any pathological changes or anomalies in the course of biological processes and lead to accumulation in the agricultural plants, and therefore may interfere with biological optimum

The article presents the results of the study on the magnesium mode of leached chernozem of Western Ciscaucasia at three rotation of grain-grass-tilled crop rotation. Magnesium in the soil is represented mainly by non-exchangeable form, the number of which is estimated at 90,18 and 91,29 % of gross reserves. Exchange forms of magnesium are 8,68 and 7,71 % respectively in arable and the subsurface layer. The share of water-soluble and organic forms account for less than 1 % - of 0.62 and 0.68 and 0.46 and 0.38% respectively. For three rotation 11-full rotation of gross stocks of magnesium in the soil in which crops were grown without fertilizers has decreased by 0.02 % (200 mg/kg), with fertilizers of 0.03 and 0.02 % (300 and 200 mg/kg). Intense magnesium has been leached from the topsoil. There was a change of the soil content of the forms of magnesium. In the rotation without fertilizer, the share of non-exchangeable magnesium in the General Fund item increased from baseline by 0.27 % in arable and 0.11% of the subsurface layer of soil that the absolute content decreased. The amount of water-soluble, exchangeable and organic magnesium of the soil decreased. Reducing the amount of water-soluble (0.05 and 0.06 %) and metabolic (0.18 and 0.02 %) of magnesium was due to its consumption of the plants. The proportion of magnesium organic part of the soil is reduced as a result of steadily declining yields, and, therefore, the amount of organic residues. In crop rotation, use of mineral fertilizers we have observed different behavior of magnesium compounds in the soil. The number of non-exchangeable magnesium decreased from baseline by 0.13 % in arable and 0,58 % of the subsurface layer of soil. The content of the exchange of magnesium increased respectively 0.43 and 0.41 %, water soluble - 0.13 and 0.10 %, and the organic part of the soil - 0.02 and 0.02 %
