System substantiation of necessity of creation of new techniques and technologies for crisis overcoming in agriculture. In the article the basic moments of a substantiation of creation of new techniques are reviewed. The system substantiation of directions of researches of the actual problems is given

This article considers a possibility of increasing adaptive potential of stevia - native substitute of sugar impacting with influence of processing BAS of green apical sprigs used for receiving seedlings
In recent years, due to the increasing aridity there was
an increase in the frequency of epiphytoties leaf disease
of barley. Therefore, we can see now how greatly
increased the need for the creation of resistant grades.
Introduction of the selection marker will significantly
speed up the breeding process for resistance to
pathogens. Employees of the All-Russian Institute of
Plant Protection recommended three genes - Rpt 1b,
Rpt 5, Rpt 6 to control the resistance to the pathogen
Pyrenophora teres for use in breeding programs in the
North Caucasus. Rpt 5 gene is one of the most efficient
one, because it determines the resistance to the eight
isolates of the fungus Pyrenophora teres of different
origin. In 2011, Australian scientists have discovered
microsatellite markers called Bmag0173 and HVM74,
closely linked to the gene Rpt5, which are used very
effectively in order to marker-assisted selection of
resistant grades in Australia and Canada. Due to the
urgency of creating new genotypes carrying resistance
genes to net blotch, that would be effective in the
Southern Federal Region, the staff of All-Russian
Scientific-research institute of Grain Crops after I.G.
Kalinenko and the All-Russian Research Institute of
Plant after N.I. Vavilov has developed a practical
strategy for the use of molecular techniques to create
barley grades resistant to this pathogen, which is being
successfully implemented
The article presents the results of studies on the use of different amounts by weight of triticale grain in feeding of young geese raised for meat. In the first group the wheat grain was 50% replaced by triticale grain, and in the second group the wheat was completely replaced by triticale grain. As a result of the experiment it has been found that the replacement of wheat by triticale in complete feed for geese provides a high growth rate but at 50 % inclusion of triticale grain the live weight at the end of the experience was110.8 g or 3% higher, as compared with the second group. It should be noted that up to 49 days old geese receiving compound feed with the 100 % replacement by triticale grain had a higher body weight. Complete replacement by triticale grain favoured the increase of carcass yield by 2.2% and decrease of body fat by 68.7 g as compared with the first group. Muscle tissue of the goslings fed the complete feed with complete replacement for triticale grain was characterized by 1% lower caloriс content than the goslings of the second group. According to biochemical composition of blood, all designed rations ensured normal metabolism in the fattened geese. The inclusion of triticale grain into the complete feed for young geese reduced their costs in the second group by 2.9%. But as a result the higher profit by 18.75 % was in the first group, which contributed to increased profitability by 2.4%. It is recommended to use up to 50% of triticale grain instead of wheat as part of complete feed for young fattening meat geese

The article presents results of studying total content
of titanium in both not fertilized and systematically
fertilized black leached soil. Science-based system of
fertilizer crop rotation allows solving problems of
sufficient balance of nutrients in the system of "soilplant-fertilizer",
increasing the quantity and
improving the quality of the crop. At the same time,
their application is active influence on the natural
environment. In the soil, there is an input of a large
set of chemical elements come along with fertilizers.
In addition, due to their physiological pH or
alkalinity, fertilizers are capable to affect the physical
and chemical properties of the soil. The use of
mineral fertilizers in scientifically based doses on the
fields of crop rotation for 33 years virtually has no
impact on the content of titanium in leached
Chernozem. In the arable layer its number increased
only by 2.1 %, and in subsurface - it is the same as in
the crop without fertilizer. Enrichment of topsoil with
titanium is due to desilication of rocks during
weathering. Due to the low solubility of titanium
minerals, they remain in the place longer, and
therefore, the content of the element in the soil
increases. As you know, fertilizers applied to the
fields of crop rotation, increase the intensity of the
biological cycle of substances and thereby enhance
the process of destruction of the parent rocks
