The objective of the present study was to investigate the supplementation effect of different treatments of whole cottonseed and full fat soybean on the diet of dairy ewes and the milk fatty acid profile and conjugated linoleic acid (CLA) content. The results indicate for both diets it is most suitable to use the second treatment in order to increase the level of cis-
9,trans-11 CLA isomer in milk. In the level of trans-10,cis-12 and cis-9, cis-11 no changes were observed in neither of the diets.
The article has covered the influence of the com-bined fungicide rex duo, suspension concentrate (310+87 g/l) on the population structure of wheat brown rust pathogen in the North Caucasus. The comparative assessment of effect of single-component preparations from different classes on the pathogen population was performed out
It is shown that under in vitro conditions, regenerated plants of Lilium caucasicum cultivated in the light of varying intensity and spectral composition didn’t have the same biometric parameters (length and width of leaves) or number of micro bulbs. There were established some specific effects of the two main areas
of photosynthetically active radiation - blue and red on the growth and development of the plants as well as on the content of photosynthetic pigments
Questions of microbial plant protection become more
relevant. The use of microorganisms can solve the following
problems: biologization of agriculture and sanitation
of soil. Application of various physical factors
affecting the microorganisms reduces their number.
This influences the efficiency of their use. This article
gives examples of the application of pressure in the
biotechnological process of microbial preparations and
their use in the process of spraying. The effect of pressure
on nonspore bacteria - Azotobacter chroococcum,
spore-forming bacteria - Bacillus megatherium and fungi
- Trichoderma viride has been presented in this article.
These microorganisms are used in the tank medium
for protecting plants against diseases and pests developed
by Ltd. "Kuban agrotehnoloogy" of Kuban State
Agrarian University. Efficiency is the simultaneous
application of tank medium of microorganisms with
herbicide. It was found that the application of the tank
medium of microorganisms for spraying is necessary to
limit the pressure of 4.5 atm. Тhe use of higher spraying
modes effects on reducing the number of viable bacteria.
This fact has not been checked against fungi
In the article we investigated the effect of the bacterial metabolites compositions (Aktoflor and Patogen) on antagonistic activity of L.acidophilus D â„– 75. It was shown the both compositions stimulate integrated antagonistic activity of L.acidophilus D â„– 75 by inducing the synthesis of the bacteriocin and decreasing the proportion of low active clones in the population. We have also shown the advantage of probiotic bacteria metabolites (Aktoflor). The results can be used to enhance the probiotic potential of the bacterial preparations
The article presents the results of studies on the effect
of processing varieties of grape cuttings of Pervenets
Magaracha using alternating electromagnetic field on
their regenerative skills. Processing the cuttings with
alternating electromagnetic field was carried out using
an induction coil for 5,10,15 and 20 min. As a control
option, the cuttings were soaked in water, as a
standard option – the cuttings were soaked for 24
hours in a 0.01% solution of IAA. Rooting was
performed in vessels with water at optimum
temperature conditions. It was found, that the use of
IAA for the first time led to the inhibition of blooming
buds. EMF treatment of cuttings with each exposure
has a stimulating effect on this indicator. Application
of EMF exposures in the 5 to 15 minutes resulted in a
significant increase in the length of shoots, compared
to the control variant and the option to IAA.
Processing cuttings with EMF exposures at 5,15 and
20 minutes resulted in a significant increase in rooting
compared with the control. Maximum rooting was
obtained at an exposure of 15 minutes. It was the same
as in the version with a standard rooting stimulant -
IAA. However, the highest yield of cuttings with 3
roots and ended up in a version with a 20-minute
exposure. Maximum number was noted on the heel of
the roots cuttings option with IAA. Treatment of
cuttings with EMF exposure 5, 10 and 20 minutes, has
also led to a significant increasing of this indicator,
respectively, 45.5; 22.7 and 79.5%. The maximum
increase in the number of roots was obtained in the
variant with exposure 20 minutes. Thus, this option
should be considered as the best one
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 accumulation features of radionuclides in the epitaphic pylaisiella moss (Pylaisia polyantha) in the territory of the city of Rostov-on-Don have been considered. The specific activities of 137Cs, 226Ra, 40K, and 232Th in the samples of moss, soils, and aerosol air have been compared. The capacity of Pylaisia polyantha to accumulate radionuclides has been estimated for four radionuclides (137Cs, 226Ra, 232Th, and 40K) with consideration for the background level. On the basis of radionuclide analysis, zones in the city of Rostov-on-Don with the highest accumulation coefficients of 137Cs, 226Ra, 40K, and 232Th were revealed. These were primarily the zones with both industrial and traffic loads and the motor transport zones
