In order to ensure import substitution and threshold
values of meat production, it is necessary to stabilize
the livestock of animals and introduce intensive
technologies. In conditions of arid steppes, the animals
of Kalmyk, Hereford and Aberdeen-Angus breeds are
best suited to stall-pasture technology. Before weaning
from mothers at 7-8 months of age, their offspring is
grown without additional feeding, just mothers’ milk.
Therefore, the growth rate of suckling young animals
rarely exceeds 850 grams of daily growth, while the
live weight reaches 400-450 kilograms at the age of 18
months, with some advantage in favor of the young
generation of Hereford breed. Using the intensive 9-
months growing at the fattening complex with feeding
from the self-feeders ensured the average daily gain in
the Kalmyk bull-calves at the level of 1398 grams, and
for the Aberdeen-Angus and Hereford breeds the
growth is 1533 grams. The highest growth energy, live
weight (661 kilograms), was with Hereford bulls.
From bulls of the native Kalmyk breed with intensive
technology of growing, a heavy body weight increase
of 331 kilograms at 18 months of age was obtained.
All tested samples of meat according to
microbiological indicators comply with the
requirements of the Technical Regulations
The study of the productive qualities of crossbred
offspring from different breeding combinations and
identifying the most effective ones providing the
maximum increase in the production of high quality
lamb while reducing its cost is an important problem
and is essential for further development of methods of
creating a new type of precocious meat and wool
sheep. In the Rostov region in the result of the
establishment of populations of meat-wool sheep there
are several groups of animals with different
characteristics and hereditary inclinations. As the base
of the work there is a method of mating and breeding
of sheep of the desired type. The article presents the
results of one of the fragments of a large complex
work in which the possibility of using three-pedigree
hybrids, created with the involvement of potential
salskaya, edilbaevskaya and intense meat-wool breed,
which is severokavkazskaya, to improve productive
quality in the breeding of sheep. We have evaluated
productivity and biological features of hybrids and
proved the economic efficiency of their use in the
production of mutton. We have given the results of the
control slaughter and assessment of qualitative
indicators of the meat of young sheep. The set of
indicators characterizing meat productivity and meat
quality revealed that the superiority of the studied
indicators remained for two - and three-bred cross
cattle. Hybrids have a higher rate of growth and
quality parameters of meat productivity. These options
are simple and complex industrial crossing are
promising and can be implemented and used on the
farms of the zone of breeding Merino sheep. Thus, the
use of crossbreeding gives an opportunity to convert a
flock of sheep in the desired direction quickly. At the
same time, three-pedigree hybrids better combine the
valuable qualities of the used species
The article reveals the issues concerning the results of the research of estimation of new early lines of maize with quick grain dry down in two areas of growing. The regression analysis which based on derived data identified intensive hybrids and the most sustainable hybrid combinations by yield and harvesting moisture of grain
The results of the research of the various agricultural technologies’ energetic efficiency are given in the article. The importance of the energy assessment for the technological process’ improvement and management of the agricultural projects is considered
The article presents the results of studying the peculiarities of growth and fruiting of trees of sweet cherry with varying density. It is established that the average yield for the years of fruiting does not depend on tree planting schemes, and higher profitability of production is marked with the scheme of 5,0×3,0 5,0×2,5 m
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
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

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 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
