This article describes the results of programming of a yield of winter wheat grain on quality and productivity of winter wheat in the conditions of teaching and experimental farm of Stavropol upland. There were given the weather conditions during the research, their influence on the formation of the structure yield and quality of winter wheat. We have presented an analysis and a comparative evaluation of the structure of the winter wheat crop, including a variety of quantitative traits: the length of the stem and ear, number of grains per ear, mass of one ear, weight of 1000 grains, tillering and overall productivity yields. This scientific article describes the technical requirements to the content: protein, gluten, vitreous, the DCO, the class of grain. In general, the results of 4-year data on leached black soils of Stavropol Upland were the largest and the best indicators on the structure of winter wheat yield and grain quality, as they were obtained with the introduction of the planned dose N126R80K72 harvest of 6.0 t/ha according to the method of calculation by V.V. Ageev, planned yield levels 5.0 and 6.0 t / ha have been achieved, the accuracy of programming (99%) was obtained by calculating the doses of fertilizers by the method of V. V. Ageev
The article presents the results of the qualitative
assessment of meat of crossbred rams. The analysis of
the data shows that crossbred rams of 2, 3 and 4
groups increased the absolute mass of muscle tissue
compared with purebred 12.3; of 18.2 and 25.6%,
respectively. Fine-wooled rams were superior in the
relative content of bone in carcasses of crossbred 1.1-
4.2 percent. Output of pulp for 1 kg of bones had the
advantage of crossbred rams 2, 3 and 4 groups
compared with purebred 0.12; 0.24 percent and 0.44
kg respectively. The analysis of the data shows that in
carcasses of young animals of all the groups the
greatest specific weight took cuts of the 1st sort.
Nevertheless, the valuable parts to carcass weight
balance was higher in the carcasses of the crossbred
calves. So, rams 2, 3 and 4 groups, this advantage was
1.9; 4.5 and 4.7%, respectively. Thus, the analysis of a
complex of indicators characterizing the quality of
meat rams of different genotypes revealed that the
superiority for the studied indices took place for two -
and three-bred animals. These options of both simple
and complex industrial crossing are promising and can
be implemented and used in the farms of Merino and
crossbred sheep

We studied the effects of heavy metal pollution on
soil phytotoxicity cities of the Rostov region. The
research objects were the soils of urbolandscape
towns: Taganrog, Novocherkassk, Gukovo, Shakhty,
Azov. The study of the soil pollution with heavy
metals was recorded in Gukovo, Shakhty, Taganrog.
The degree of pollution of the studied cities form the
following row: Gukovo > Shakhty > Taganrog >
basics > Novocherkassk. The research was carried
out in 2011-2015 at the Department of ecology and
environmental Sciences of southern Federal
University. In most cases, there was a direct
correlation between pollutant concentration and the
degree of deterioration of the studied soil properties.
Used biological indicators are informative for
monitoring of urban soils polluted with heavy metal.
The degree of informativity of biological indicators
form the following row: root length > germination
>length of shoots. The results of the study can be
used for monitoring and diagnosing the condition of
contaminated soils, in the assessment of
environmental impact, risk assessment of natural and
synthetic disasters, the development of regional
standards on the content of heavy metals in soil and
in other environmental and industrial activities

0,19%, labile phosphorus - 12,2-12,9mg / kg soil total
potassium -1,7-2,0%, exchange potassium- 386mg / kg
soil. The degree of saturation of bases is 80-90%. The
amount of absorbed bases is 30-40 m ekvg/ 100 g of
soil. The reaction of the soil solution is weakly alkaline
(PH water 8.0-8.2). The predecessor is winter wheat.
General Agrotechnics is recommended for a given soil
and climate of region. Solid mineral fertilizer were applied
as mineral fertilizers in combination with organic
fertilizer in the form of half-decomposed cattle manure. According to agro-climatic zonation the northern zone
of the Krasnodar region, where the research was conducted,
is related to the zone of insufficient watering
with hydrothermal coefficient 0.7-0.9 with an annual
rainfall of 350.5 to 899.8 mm. During the autumn and
winter period, which determines the accumulation of
water in the soil, from 150.3 to 426.8 mm of rain falls
or 30,4-68,9% of the annual amount. During the vegetation
of sugar beet from germination to harvest -112,0-
588,9mm of rain falls, with an average daily temperature
of the air 16,5-20,000С, including the period of the
greatest growth of roots and accumulation of sugar
from 3.2 to 557.1 of rain falls with air temperature
19,5-28,800С. Hydrothermal index is 0,01-2,83. During
the years of the research 19% of years have been characterized
as unfavorable (hydrothermal index 0.67),
44% of years as moderate on moisture supply and temperature
conditions (hydrothermal index 0.99) and 37%
of years as favorable (hydrothermal index 1.05). The
generalization of the research results obtained by us in
the long-term stationary experiment, allowed us to estimate
the impact of different standards and systems of
fertilizer on the productivity of sugar beet and sugar
content in the roots. On average, during the years of
research, the root harvest under the influence of fertilizer
amounted to 36,7-45,6 t / ha per unit area with the
addition to the control variant, that isn’t manurable,
amounted from 6.6 to 15.5 t / ha. The highest yield of
root is 43,0-45,6 t / ha which was obtained with systems
of fertilizer with complete mineral nutrition
In the article we present the results of the researches of influence of low temperatures on the qualitative characteristics of pectin substances of cherry fruit and berries currant.

Analytical survey has revealed that technologies of
flaxseed oil processing used nowadays are able to
produce technical flaxseed oil if the output is high and
food flaxseed oil if the output is low. The objective of
this work is to reason the most effective method to
increase the output of food flaxseed oil while keeping
its quality high. In this article a comparison has been
made between single cold pressing of flaxseeds
without preliminary preparation with microwave
processing, as well as traditional (conductive) heating
with traditional heating under vacuum. The object of
the research is samples of flaxseeds (high quality
variety VNIIMK-620 which contains 56.28% of
linolenic acid in its fatty acid composition. It has been
established, that the use of preliminary microwave
processing enables to increase the output of oil
compared to a single cold pressing without any
processing, whereby the mass content of oil in oil cake
can be reduced by 2.2%. At the same time the
indicators of acid number and peroxide value are
increased by 0,05 mg KOH/g and 0.37 mmol of
active oxygen/kg correspondingly. Preliminary
traditional heating of seeds before cold pressing
enables to increase the output of oil, though not
considerably, compared with preliminary microwave
processing. At the same time the changes in acid
number and peroxide value are similar to cold pressing
with microwave processing. The use of vacuum when heating seeds in a traditional way does not influence
the output of flaxseed oil but enables to decrease acid
number and peroxide value to the level which is
characteristic for the oil in original seeds. Thus, it is
reasonable to use preliminary microwave processing
under vacuum before cold pressing with the view to
produce food flaxseed oil of high quality in terms of
oxidative deterioration and the increase of its output
