Early-ripening white cabbage has a special place
among the vegetables cultivated in Kuban region. It
opens the pipeline of vegetables from the open
ground and is supplied to other regions at a time
when shortage of vegetables of domestic production
is felt the most. Modern producer requirements to
domestic hybrids are the highest - product quality,
uniformity and productivity should not concede to
foreign analogues. Ways to improve the quality of
early ripening hybrids: development of lines based on
modern foreign hybrids, high uniformity of lines by
morphological and economic traits. Development of
male sterile lines and dihaploid lines in culture in
vitro can more successfully solve the problem of
quality of early ripening hybrids. The use of the
above methods and approaches helped develop series
of inbred lines - gene sources for complex agronomic
traits. On the vase of obtained lines promising earlyripening
hybrids were developed. One of the hybrids,
Ritsa F1, entered the State register of breeding
achievements. Advantages of the hybrid: earliness,
uniformity and high marketability of heads, high
productivity. According to results of contest trial new
hybrid Milana F1 is passed for State trial, this hybrid
has high productivity potential for growing in sale
cropping. Both hybrids were produced with the
participation of male sterile line Dt46f, resistant to
fusarium. High quality seeds of these hybrids were
produced in a greenhouse in direct crop for a wide
industrial and environmental testing
This article presents the studying results of new premixes of domestic production using efficiency based on processed products, in particular - oil cakes. The research was carried out in the conditions of the second-order pedigree reproductor in LLC "Svetly" in the Svetloyarsky district of the Volgograd region in the period from 2015 to 2017. During the scientific and economic experience, the authors revealed the new fodder additives positive influence on the laying hens’ egg productivity, on the eggs morphological and incubation rates and on the got young birds. The use of premixes in layer diet, which included the fodder concentrate from the plant raw material "Sarepta" and Camelina seed oil cake, contributed to the increase in the hens laying capacity, in general, the group received in 249 and 310 pieces more than in the control one. The egg average weight from the chickens of the control group was 60.89 g; from the first experimental it was 61.33 g; from the second experimental it was 61.39 g, which was higher than in the control one, respectively, by 0.44 g and 0.50 g. While the hatching eggs morphological indices analysis, it was revealed that all parameters are within the permissible limits of the physiological norm. Fertilization of eggs in the control group was at the level of 89.33%, which is lower than in the experimental groups. As a whole, the eggs' production in groups was 20.00% in the control, 17.33% in the 1st group, and 16.00% in the 2nd test group
The article presents results of the evaluation of the
physiological aspects of growth and fruiting of peach

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 modern cattle breeding in Russia is
characterized by dynamic development, development
of intensive technologies, increase in production, but
at the same time, there are problems of increase in
production of milk due to increase of dairy efficiency
of cows at the most effective manifestation of the
available level of their genetic potential. For the
solution of this problem, i.e. for genetic
improvement of dairy cattle, creation of new breeds,
intra pedigree or zone types, more than 100 thousand
of bulls with high genetics, and also 430 thousand
heifers were delivered to Russia for the last 10 years.
In this regard, the purpose of our researches was to
study the level of genetic potential of dairy cows in
breeding farms of "Nasha Rodina" of Gulkevichsky
region, Vasyurinsky milk farm of Dinsky region, the
Firm «Agrocomplex» of Vyselkovskiy region
(Gazyrskoye enterprise), "Urozhay" of Kanevskoy
region from 2000 to 2014, by using bulls of
Golshtinsky breed. Researches have shown that in
farms of the Krasnodar region producers with the
high level of potential from 10791,0 kg to 12045 kg
on milk were yield used on a breeding uterine
livestock; from 4,22 to 4,40% of fat; from 3,32 to
3,49% of protein in milk. As a result the level of
potential of daughters of bulls and cows in herds of
farms was from 7774 to 9144 kg of milk; from 3,89
to 4,05% of fat; from 3,26 to 3,67% of protein in
milk. However, genetic potential of new generation
of animals is shown not completely. It is influenced
by partial compliance of the created technological
conditions of biology of animals, and indicators of
breeding value of producers, with their prepatent
indicators. Calculations of breeding value indexes of
bulls – fathers of cows in the herd of "Urozhay" have
shown that each bull has its breeding value, an
ability to transfer the qualities to posterity. Bulls of
Golshtinsky breed of red – motley color ( Pan 2037
and Tulup 78160689), by results of comparison of
milk yields of daughters, mothers and
contemporaries, had negative prepatent indexes of
milk yield and milk protein content (according to
F.F. Eysper and V. Sidorova). The data confirm the
need of carrying out an obligatory index assessment
of bulls before their use on the farm in order to avoid receiving descendants with low dairy efficiency
The article presents results of the study of yield, mechanical composition and quality of bunches of newest white grapevine varieties called Artemis, Sauvignon tamanskii and Inkroche tamanskii, in the conditions of Taman in the Krasnodar region. The yield of the studied genotypes ranged from 10.4 to 13.3 t / ha: the highest yield was in Artemis, and the lowest – in Sauvignon tamanskii. The average weight of the bunch was in Sauvignon tamanskii (152 g), the variety Artemis had 143 g and Inkroche tamanskii had 130 g of bunch weight. The percentage of berries in clusters ranged from 95.3 in Artemis to 95.9 in Inkroche tamanskii and Sauvignon tamanskii. The ratio of fruit mass to the mass of crests was 20.3 in the varieties of Artemis and 23.5 in Inkroche tamanskii and Sauvignon tamanskii. In genotypes of Artemis, Sauvignon and Inkroche Taman Taman the weight of 100 berries was 200, 160 and 130 g, respectively, the mass of 100 seeds - 4.6; 3.1 and 2.9 g, the average weight of the pulp from the juice to the weight of the skin - 24.3; 19.5; 15.9. The percentage of pulp and juice in clusters of the studied varieties was 85,9-89,1%, and the ratio of pulp to juice to the solid residue 6,1-8,2. Yield of musts from the studied sample was 74,5-75,4%. The content of sugars in the berries (17,5-19,6 g / 100 cm3) was dependent on the yield, the characteristics of varieties and timing of the harvest, but the harvest was favorable for the production of beverages and wine materials
The researches on the mustard protein-containing fodder concentrate "Gorlinka" use were carried out during 2015-2016 in the laboratories of Volgograd state agrarian university, as well as at LLC "Donagrogaz" in the Frolovsky district of the Volgograd region. During the research, the authors studied the new high protein fodder additive influence on the digestibility and feeds absorbency, as well as on the blood morphological and biochemical parameters. During the research, it was established that the used fodder additive has a positive influence on the dynamics of the digestibility coefficients and the nitrogen balance. During the physiological experiment, all the experimental cows had a positive nitrogen balance, in the control group it was 9.8 g (the lowest value), in the second group, it was 12.6 g, and in the first one, it was 12.0. When determining the experimental animals’ blood biochemical and morphological parameters the content of the studied components corresponds to the physiological norms. The average daily milk yield for the analogues from the 1st test group was higher as compared to the control, by 1.01 kg, or 5.1%. The mean daily milk yield of the control group was also lower than for the cows of the 2nd test group by 1.45 kg, or 7.4%
In the article, long-term data (2007-2015) of biometric parameters of an elevated part of plants are provided. Assessment of prospects of five introduced botanical species of juniper is carried out and recommendations about their use in landscaping are made. From 25 studied grades of junipers of types: Cossack, Sredniy, Virginia, Horizontal and Scaly we have established very perspective, perspective and a little perspective for gardening in the conditions of a foothill zone of the Krasnodar region
Acidic properties of the mineral matrix of meadow
chernozem and meadow-boggy soils of Krasnodar
region are characterized by a total adsorption capacity
of ammonia in the range of 32-61 µmol / g. The lowest
acidity of the matrix was observed under conditions of
permanent rice cultivation for 80 years (32-
33 µmol NH3/g). The mineral matrix of rice soils
depends on the meliorative state and the granulometric
composition of these soils. At low fields of meadowboggy
soils, heavier in granulometric composition, the
total acidity of the mineral matrix is 51-
53 µmol NH3/g on high checks of lighter meadow
chernozem soils – 34-45 µmol NH3/g. In the upper
soil, with a less acidic matrix, the Fe3+ content
increases and the amount of Fe2+ decreases. The
reverse pattern is found in the lower soil with more
pronounced acidic properties of the matrix. A
proportional relationship between the humus content
and the acidic properties of the mineral matrix is
found. The highest yield of rice is formed on meadow
chernozem soils with a less acidic mineral matrix
The successful development of livestock requires
maintaining and further increasing of the genetic
potential, the basis for the manifestation of which is
the adequite balanced feeding. Currently, one of the
most urgent problems of livestock breeding is to find
ways for reduction of the negative impact of various
feeding factors on the animals. In industrial
conditions, it is difficult to exclude various feed
stresses, which lead to a decrease in productivity,
survival rate and ill health of animals and poultry.
The work summarizes the research in this direction,
taking into account the achievements of domestic
and foreign authors. A serious problem of feed
producing companies and livestock farms is the grain
and compound feed affection with fungi and their
metabolic products - mycotoxins. Based on the
results of the research of several authors, the ways of
solving this problem were identified and
recommendations on the reduction of the negative
effect on the body were provided. It is noted, that
one of the best and effective ways to reduce the
negative effect of mycotoxins on the body is a
method of administration of adsorbents in animal
feed. But it should be taken into consideration that in
order to maximize the protection against mycotoxins
and minimize their harmful effects on the body of
animals it is necessary to use preparations, which
include adsorbents of organic and inorganic nature,
as well as to comply with the dosage of their
introduction into the diets of animals and poultry.The
progressive forms of preparations of a new
generation, solving problems of the negative impact
of feeding factors, include probiotics, which contain
some bacteria, immobilized on the solid particles, so
that they inhabit the intestine faster. Modern
biological complexes have immune correcting
properties, increase non-specific resistance of the
organism, normalize microbiocenosis of
gastrointestinal tract, and stimulate the functional
activity of the digestive system. Therefore, it is
necessary to use feed additives with detoxification
properties as part of animal compound feed,
according to recommendations on their application in
appropriate dosages
