In order to find compounds that increase sugar beet
resistance to the adverse effects of herbicides, a
series of pyridylhydrazone derivatives have been
synthesized. The protective effect of new
compounds for the herbicide mixture Betanal,
Lontrel and Super Zeleke was studied in field
conditions. The effect of pyridylhydrazones on the
synthesis of photosynthetic pigments in leaves was
investigated. Substances with a high protective
effect were found
The researches of the quality of 34 donor cows estrus
detection during superovulation induction period, after
Pg F2α injections were carried out. The clinical heat
index was set up and applied. The clinical heat index
is clinical prognostic criterion of successfulness of
superovulation induction and embryo productivity. It
was shown that donor cows showing signs of oestrus
during 48-72 hours after Pg F2α injections had the
best embryo collection qualities while certain increase
of degenerated or aborted embryos and unfertilized
oocytes is determined in embryo collections from
cows showing signs of oestrus before or after that
period
The article presents the results of studying the impact of different options for cutting fruit vines on the growth and productivity of shoots of the grapes. The obtained experimental data indicate the excessive overload of vines with eyes and shoots when performing contour trimming bushes without normalizing the choice of shoots, in comparison with other variants of experience. A significant increase of eyes on the vines when performing contour cutting was because during this method of cutting, the cutoff is at a certain level all the shoots are horizontal on the arm vines. A big load of vines shoots when performing contour cutting has reduced the length of shoots at 48 – 51%, and leaf area developed on the shoots of 53 – 54%. While the lowest productivity was different shoots developed on the vines in 3 variant, because here the contour cutting vines was not accompanied by a subsequent breaking of superfluous shoots, which have overloaded the bushes shoots. At the same time, contour cutting vines with subsequent breaking of the normalizing excess shoots were allowed to grow for fruiting the bushes a sufficient amount of normally developed shoots with high productivity and good quality bunches
The article presents the comparative assessment of
economic traits of Holstein cows of various ecogenetic
types in the Volgograd region, the Russian
Federation. The study of adaptive ability of Holstein
cattle imported from the United States (245 heads),
Denmark (245 heads), Germany (386 heads), and
Australia (250 heads) has been carried out based on
breeding plant OOO "Donskoye" in Russia since 2006.
The milk producing ability of the animals was studied
during the period of first three lactations. The cows
imported from the United States showed the maximum
productivity. The cows from the USA and Germany
were registered to have the highest fat content in milk.
The mathematical modeling for predicting production
processes revealed that with respect to the milk yield,
the Holsteins of Danish selection were superior to the
cows of American, German, and Australian selections
by the fifth lactation. The high correlation between the
milk yield and the body weight, as well as between the
body weight and the fat content of milk from Holstein
cows of various selections has been established. The
cows of Danish, German, and Australian selections
showed a positive correlation between economic traits
and genetic parameters for the period of three
lactations. The cows from Australia have been proved
to have higher indices of protein composition of milk
(the total nitrogen content, the amount of essential
amino acids). The level of the adaptive ability of the
animals of the same breed but different eco-genetic
types has been found to be stable
Nowadays, fruit trees are subjected to influence of
abiotic stress-factors. The reaction of fruit plants on the
influence of media plays an important role. Experiments
were conducted in two (Northern and Central) fruit
zones of the Krasnodar region since 2013 to 2015, there
was shown the possibility of application of
hydroabsorbents as a stable source of water supply of
fruit trees in specific natural conditions of the South of
Russia in the conditions of field experiment. There were
shown the peculiarities of technological ways of water
supply of fruit trees in specific natural conditions of the
south of Russia. There was determined that the necessity
in watering of a garden’s plots with the use of
hydroabsorbents Ecogel-1 and Ecogel-2 with the
supporting of soil’s moisture in 80% in Northern zone
in the end of May, in central fruit zone in the middle of
May. There was proven that the application of
hydroabsorbents Ecogel-1 and Ecogel-2 guarantees the
stable water supply in limits of 75-80% from NV since
planting in apple-trees of varieties of Renet Simirenko
and Golden Delicious grafted on the stock M9 and
planted on the scheme 4,0 х 1,0 м during three years.
The work of the system of “soil-roots-leaves”

The article contains complex research results dedicated
of reproduction the cattle of the animal breeding
industry in the agricultural holding called “Kuban”.
Key indicators characterizing reproductive function at
cows were set; they were estimated in terms of the
plans of the economy in the milk cattle breeding
industry. The reduced values of the birth-rate of calves
were revealed on 100 cows and in the term of the
production use of cows, their main reasons were set.
The performed calculations prove the possibility of
increasing the profitability of milk production
The article contains research results on the influence
of duration of the first lactation period of sows on
reproductive qualities. The authors have detected
basic problems which reduce indices reproduction of
purebred pigs of the breed of Yorkshire and hybrids
of F1 (Yorkshire x Landras) under conditions of a
new complex. It was found that because of the
increase in duration of lactation period of the sows it
is impossible to increase the safety of the piglets
with a reduced live mass (from big nests and slow in
growth) and improve the reproductive quality of
sows. This method has been used in the economy
what led to a notable improvement in the indices of
pig breeding
The article studies the influence of the interaction of two technologies of plant protection: breeding- immunological and chemical. The studies were conducted on the varieties and lines of soft winter, durum wheat and triticale, established in Krasnodar research institute named after P. P. Lukyanenko, and also, on varieties of an alien and foreign selection. When considering the correlations in the group of genotypes, forming a necrotic type of reaction to the introduction of the pathogen (the first group of varieties), the significant negative correlation (r - 0,76) between the change in the mass of 1000 grains and the number of unproductive stems formed by one plan was established. The model of the severity of brown rust pathogen in sparse crops of wheat has been collaborated. According to the model, the development of the pathogen in the tissues of the leaves of the host plant leads initially to a change in the relations of the productive and unproductive stems. The change of these parameters significantly affects on the variability of indicators such as the mass of grains from one ear, number of grains per ear and 1000 grain weight. Negligible volatility of weight for 1000 grains suggests that the major losses of productivity in the flowering stage are due to abortive flowers. This model can explain the increase in the mass of 1000 grains in some varieties for tolerance change experiments with the defeat of plants of P. Triticina on micro-plots
In order to reduce the impact of stress factors on the
body of pigs, new technologies and efficient
veterinary and preventive measures in breeding and
cultivation are being developed. The results of our
scientific and economic experiments found that the use
in daily diets of pregnant and lactating sows according
to our schemes of biological additives (to finish /
day.): Laktobifid (1 g), Immunobak (1 g), Provagen
(10 g ) Vetom 1.1 (50 mg / kg body weight), Bacell
(0.3% by weight of the feed) and Monosporin (10
mL), contributes to the improvement of their
reproductive qualities: for twins - on 2,2-12,2% by
krupnoplodnosti - by 8,0-10,7%, for milk - by 8,9-
36,5%, at the preservation of pigs - by 1,3-8,3%, by
weight of the nest 2 months of age - 22 , 9-38,9%
compared with the control. At weaning piglets from
sows experimental groups indicators of natural
resistance were significantly higher. The best
reproductive performance were observed in sows
treated with diet and probiotic supplements
Immunobak Bacell combined with Monosporin . The
results of these experiments revealed adaptogenic
properties of the studied additives, their ability to
mitigate the impacts of technological stresses,
reducing as a result of the cost of the products. Of
great practical importance is the ability to predict the
effectiveness of the use of additives which have antistress
effect, depending on the body weight of
animals, their age, frequency and duration of their
application before and after the impact of
technological stressors in the suckling period, the
periods of rearing and fattening up of live weight and
100 и 120 kg
We have performed an analysis of the current state of
rice seed production in the Krasnodar region. It is
shown that over the last 10 years in Kuban a full
variety changing took place, which was caused by
State support of rice seed production on the federal
and the regional levels. Agricultural producers of the
Krasnodar region have completely stopped cultivation
of medium-ripening rice of Liman variety, increasing
acreage of new varieties such as Victoriya, Sonet,
Diamant, etc. which allowed to increase crop yield
from 47,1 centner/ha in 2006 to 63,0 centners/ha in
2015 and to improve the quality of commercial grain,
decreasing the content of red-grain forms average in
the Krasnodar region from 20,5% in 2006 to 1,8% in
2015. Legal basis of realization of state agrarian
policy in the field of seed production of agricultural
crops, including rice is reviewed, recent changes in
the legislation of the Krasnodar region concerning
seed production of agricultural crops are shown, as it
was reflected in the Law of the Krasnodar region №
3062-KZ dated 28.11.2014 "On the regulation of
certain relations in the field of seed production in the
Krasnodar region". Areas contributing to the
development of the rice seed production in the Kuban
region are identified for further conducting of variety
changing, introducing new high-yielding varieties into
production as well as varieties of special purpose for
import substitution
