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 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
Using of seedling method for growing early potatoes
accelerates the starting processes of growth and
development of plants, and the application of
temporary covers of the nonwoven covering materials
protects the landing from sudden temperature changes
and relapsing frost. To receive seedlings of early
potatoes we used standard seed tubers of 60-80 g
weigh of the following varieties: Agata, Red Scarlett,
Kislovodskiy, Vershininskiy and Sheri. By the time of
planting in the ground, depending on the varieties, the
height of seedling was from 13 to 26 cm, the number
of leaves - 7-10 pieces. Conducting of trial unearthing
of potato showed that on 45 days after transplanting
into the ground (the second decade of May), it is
possible to receive up to 10, 5-11, 4 t/ha (Agata and
Red Scarlett varieties). On 55 days (the third decade of
May), the yield reached 26, 4 t/ha of standard tubers,
and in the first decade of June the yield was from 26, 4
to 50, 6 t/ha. The maximum yield of standard tubers of
50, 6 t/ha was obtained by lifting on 65 days with the
Red Scarlett variety. In the terms of the Astrakhan
region the growing of early potato by seedling method
with using of temporary cover allows to receive the
ultra-early harvest of marketable tubers in the II-III
decade of May
In order to find compounds that increase sugar beet resistance to the adverse effects of herbicides, a series of naphthalenesulfonamides 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 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
We have selected a group of test animals and formed a
set of techniques for the research. The article gives an
evaluation of fattening qualities (precocity, average
daily gain, feed consumption per 1 kg of gain) of
purebred and crossbred pigs. We present the dynamics
of body weight and body length for the experimental
pigs, productive qualities, the thickness of back fat of
experimental animals to achieve the 100 and 130 kg of
live weight
We have studied the effect of presowing enrichment
with copper on the seed yield of rice. We have found
optimum concentration of water solution of copper,
which provides higher yields of seeds and evaluated
the impact of the enrichment with copper on the
growth processes in the plants of rice. The studies
were conducted in elite seed-growing enterprise
"Krasnoe" of All-Russian Research Institute of rice.
It was found that for rice-growing farms of the
Kuban region with the aim of increasing the quantity
and quality of grain yield it is necessary to make
sowing of rice seeds enriched with copper. This
application should be carried out by wetting the rice
seeds with 0,5 % water solution of the microelement
with a semi-dry method, i.e. the rate of 10 liter
working solution of copper in 1 ton of seed. The
article proves the economic feasibility of enrichment
of rice seeds with copper

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
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%
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
