The study was carried out during 2010-2015 years in the
All-Russian research Institute of Grain Crops named
after I.G. Kalinenko (the laboratory of the cultivation
technology of plowing crops), situated in the southern
soil-climatic zone of the Rostov region, which is characterized
with the unstable and insufficient humidity. The
trials were conducted on the heavy loamy, calcareous
chernozem obyknovenny (natural blacksoil). The object
of the study was the grain sorghum variety ‘Zernogradskoe
53’, approved to use in the Rostov region. The agroclimatic
conditions during the years significantly differed
during the vegetation in the amount of precipitations
(from 110.2 mm in 2010 to 200.2 mm in 2013) and
in the temperature regime (from 2512.9 0С in 2010 to
2788.8 ºÐ¡ in 2015), that allowed evaluating the grain
sorghum productivity more objectively. The article gives
the study results of the effect of the weather conditions
on the duration of vegetation, productivity and grain
quality (content of protein, oil, ash and fiber). The article
showed the estimated interconnection among the sum of
active temperatures, precipitations and hydrothermal
coefficient during the sorghum vegetation with the principal
economic-valuable traits of grain sorghum. The
sum of active temperatures showed the greatest effect on
the duration of the vegetation (r=0.89); the sum of precipitations
during the vegetation had the greatest effect
on the productivity (r=0.80). There was determined the
strongest positive correlation of the sum of active temperatures
with the content of protein in the grain sorghum
kernels (r=0.80) and the average negative correlation
with the content of oil (r=-0.69). The sums of active
temperatures and precipitations, when the grain sorghum
gives the largest productivity, were established

The article reveals issues concerning three years
research about the rate of influence complex
water soluble fertilizers in seed treatment and
treatment vegetative plant in phase 3-5 and 7-8
leaves for grain yield increase. In the process of
research were determined summarized water
consumption and coefficient of water
consumption, measuring of morphological signs,
were given economical estimation of using
complex water soluble fertilizers in corn grain
yield increase. The research shows the efficiency
of seed treatment of average corn hybrid
Krasnodarskiy 377 AMV by complex water
soluble fertilizer Lignohumate potassium at dose
0,5 l/t. Grain yield increase in mentioned variant
was 4,4 c/ha in comparison with variant of
distilled water treatment. The same grain yield
increase was got by using in seed treatment the
mixture of Albit, 0,05 l/t with Lignohumate
potassium, 0,5 l/t. the treatment of vegetative
plants in phase 3-5 leaves when were sowed non
treated seed were less efficient than in phase 7-8
leaves, where grain yield increase was 4,5 c/ha.
Seed treatment of Lignohumate potassium in
combination with vegetative plants treatment in
phase 7-8 leaves by using Megamix, Bionekskemi
and Lignohumate potassium allowed to get
grain yield level 80,3-80,8 c/ha
The effectiveness of drug treatment of Korenastyi on productiveness and quality of sweet peppers and egg-plants was shown
This article presents the results of using "Gorlinka"
mustard protein-containing feed concentrate, instead
of sunflower meal in the feeding of broiler chickens
of the cross of "Cobb-500". The studies were
conducted in the conditions of Krasnodonskaya
Poultry farm of the Ilovlinskiy district of the
Volgograd region. Replacing sunflower meal with a
product of processing of oilseeds which is "Gorlinka"
mustard protein-containing concentrate, in the feed
mixture in the experimental broilers had a positive
impact on the productivity, physiological state of the
birds, product quality and economic performance.
The use of this mustard protein-containing feed
concentrate in feeding of meat birds contributes to the increase of live weight by 3.46-of 6.65% and
slaughter yield by 1.38-1.98% and improvement of
quality indicators of the carcasses. Morphological and
biochemical parameters in experimental broiler
chickens in all the groups were within the
physiological norm, which indicates a normally
occurring redox processes in the poultry organism.
However, adding "Gorlinka" mustard proteincontaining
feed concentrate into experimental feed for
broiler chickens contributed to the increase in the
content of total protein, calcium, phosphorus in blood
serum in comparison with analogues from the control
group that received sunflower cake. As a result of the
research, the economic effect in the experimental
groups was up 710,40-1085,53 rubles
Plants of winter wheat suppress weeds quite well, however, the use of herbicides is required, which prevents the new clogging up of soil. Under surface tillage it was observed a greater spread of weeds than under mold-board plowing. Introduction of the herbicide Lancelot regardless of ways of tillage has reduced this rate in 5.8 times. An important means of regulating of vital functions of soil microflora is tillage. 40% of all expenses ac-counted for the soil treatment required for cultivation of crops. Therefore it is important to study the effect of tillage on the course of microbiological processes in the upper 0-30 cm layer. The intensity of the decomposition of plant material by linen cloths method objectively reflects the status and activity of soil microflora. One of the signs of cultural soil condition is its ability of nitrification. Nitrification process is particularly slow in early spring, because this time the microbiological activity is weak because of low soil temperature. When the soil is progressing the number of nitrates increases and reaches its peak in summer, after that the process is fading. Studies have shown that under surface tillage, microbiological processes of decomposition of cellulose and the ability of soil nitrification compared with moldboard plowing are higher. The components of yield structure show features of yield formation. Tillage did not have an essential effect on crop structure elements. Application of herbicide Lancelot has significantly increased the number of productive stalks (7.3-10%) and mass of 1000 grains on 1.8 g or 4.5%. Grain yield of winter wheat did not depend on the primary tillage (57.5-56.5 kg/ha). Application of herbicide Lance-lot has allowed to receive allowance (on average for 2 years) 5.0 kg/ha. Grain quality indicators of winter wheat depend both on the hereditary traits and preferred growing conditions. The amount of gluten is not dependent on the main tillage, while the introduction of herbicide has increased gluten to 1.4%. Calculation of economic and bio-energy efficiency showed that the use of surface treatment in the cultivation of winter wheat on soil ordinarily is worthwhile
Two granular formulations of phosphorus biofertilizers
combining rock phosphate and two highly active
phosphate solubilizing strains: Acinetobacter species
305 and Pseudomonas species 181а have been investigated.
Granules of about 3 mm in size were obtained
by contact-convective drying of a mixture of ground
ore, concentrated biomass of two different strains,
starch and glucose. Micro granules with size of 0.1-
0.5 mm were obtained by spray drying the biomass of
two different strains and application of dried cells on the particles of the ground ore. Starch was used as a
binder. In the model liquid medium it was shown that
the microorganisms have retained the ability to solubilize
mineral phosphates in granular formulations prepared.
In laboratory pot trial on marigold (Tagetes
patula) it was demonstrated that both formulations of
biofertilizer increased the dry weight of the plants to
the same level as that of chemical fertilizer - double
superphosphate, but were inferior in the concentration
of phosphorus in plants. Both formulations exceeded
the effectiveness of rock phosphate and biomass used
as biofertilizers both separately and jointly. No significant
differences were noted between the two
strains and the two granular formulations both for
plant dry weight, and the content of phosphorus
therein. Both granular formulations of biofertilizer
retained their structure and avoided aggregating over a
year of storage at 4 oC. The average persistence of
living cells in the microbeads was about 1.5%, in
granules - 32 %
The article discusses development factors in agricultural production and marks the difficulties impeding positive dynamics: low levels of accessibility to credits, capital intensity, power availability, organic and mineral fertilizers application, infrastructure of the commodity market, particularly small farms. It refers to the most important external and internal production factors. Among the limiting factors we should note high lending cost, fiscal, changes in tax policy, volatility and price disparity, lack of working capital, financial risks, depreciation of fixed assets, problems with the mechanization in the field of production, shortage of skilled workers. In the article we note factors of increasing economic efficiency including government assistance in the area of lending, incentive policy, insurance, innovation promote, using of advanced domestic and foreign technologies in the modernization processes of production, assistance in staff professional development. It is noted that to improve the financial sustainability of regional agricultural companies today we need a more equitable economic distribution mechanism using of state regulation funds and a support to specific producers and processors of agricultural products, taking into account natural, territorial rents, levels of use of the resource potential, production costs, final contribution to the formation of a regional product. This approach will improve the effectiveness of the targeted direct government support of the particular agricultural industry, including small farms
In the long-term stationary experiment since 1968, we have studied the influence of crop rotation on soil fertility and productivity. The modernization schemes of field rotations in the direction of alternation crop change were held 40 years later, by introducing a scheme of oilseeds (canola, soy). According to the research, the authors made conclusions about the efficiency of cultivation of oil crops in crop rotations in the region. The resulting materials can be used in the development of crop rotations schemes for forest-steppe of Western Siberia
