In the experimental work, we studied the effect of the
inulin prebiotic on the growth, development and
efficiency of growing broiler chickens of the Isa cross.
In accordance with the scheme of the experiment, the
first control group was fed a complete feed (CF) by
periods of growth. In the second group, inulin was
added to the CF for the first 21 days of growth. In the
third group prebiotic was added to the CF at the same
rate throughout the whole period of rearing the chicks
(42 days). In the second and third groups, we found the
tendency to increase the intensity of growth rate in
poultry by 1.6 and 3.0%, respectively, compared with
the control. Feed costs for weight gain were decreased
by 2.1-2.7%. In the chime of the blind processes of the
intestine of the chickens of 2-3 experimental groups it
was found the reduction of staphylococci and
enterococci CFU, while similar to the control group
lactobacilli CFU. The muscle tissue in the chickens of
experimental groups had greater protein content. The
optimal range of indicators is the use of inulin for the
first 21 days of rearing poultry. Because of the
production audit, an increase in live weight of chickens
was found, in the experimental group by 2.7% (p ≤
0.05), a decrease of feed costs by 7.5%, increase of the
survival rate of poultry by 2.0% and profitability by
3.1%
The article gives an assessment of physical and
chemical properties of muscle and fatty tissue,

Searching for new promising plant growth regulators
and antidotes, we have synthesized a series of Nsubstituted
naphthalene-2-sulfonylamides. Synthesized
compounds have been studied as potential growth
regulators of economically significant crops - winter
wheat, sugar beet, sunflower, soybean, and herbicide
antidotes for sunflower growing plants. The substances
with high growth stimulating and antidote effect were
found

For the purpose of preservation of soil fertility at
relatively low economic expenses, we have conducted
researches on optimization of doses and combinations
of mineral fertilizers by cultivation of field corn hybrid
called "Krasnodar 382" in a stationary field experiment
of the Department of agrochemistry in the training farm
"Kuban", in the conditions of the leached chernozem of
Central zone of the Krasnodar region. The main impact
on receiving high-quality corn gives the content of plant
nutrients in soil. Our researches showed that the
application of the complete fertilizer in various doses
has had influence on the content of essential plant
nutrients in the soil. The maximal values of the content
of mineral nitrogen, available phosphorus and
exchangeable potassium during all phases of vegetation
have been got in options with double N60P60K40 and
triple N90P90K60 dose of the complete fertilizer.
Sufficient supplying the soil with plant nutrients by
fertilizing has entailed the enhance of corn yield. Great
crop of corn has been reaped during the experiment.
After three years of researches, the productivity has
reached averaged 58,7 cwt/hectare. The greatest
productivity has been received in the option with
application of triple and double dose of the complete
fertilizer and amounted 68,5 and 68,0 cwt/hectare, what
is 47% and 45,9% more, compared to the option
without any application of fertilizers. The main
substance, which defines nutritional value of corn, is
proteins. Application of fertilizers under the conditions
of our experiment has promoted enhancing the protein
content in corn. The application of mineral fertilizers
has promoted increase of the content of crude protein in
corn. Maximal it was in option with application of the
complete mineral fertilizer in the double dose of
N60P60K40 – 9.6%, when reaped protein has amounted 6,5 cwt/hectare. Therefore, it is possible to conclude
that it is most expedient to fertilize field corn with the
dose of N60P60K40 and N90P90K60
The reaction of winter wheat cultivar ‘Antonina’ on the level of fertility and doses of fertilizers on crop productivity was studied. Investigations are carried out in multivariate 11 –course crop and grain-grass rotation stationary: factor ‘A’- the fertility of the soil; factor ‘B’ - fertilizer system; factor ‘C’ - the system of plants protection; factor ‘D’ - the main methods of soil tillage. Four models of soil fertility levels were studied in the experiment: А0 - initial (natural background); А1 - average (200 kg / ha Р2О5 and 200 t / ha of solid manure); А2 - high (double dose); at А3 - high (tripled) on three backgrounds of basic soil cultivation: nonmoldboard, recommended, moldboard with deep bursting and without the application of tillage (direct seeding and the natural rate of soil fertility). The soil is heavy leached black humus with humus content in the arable layer of 2.5% - 2.9%. On the basis of proven researches it was found that for the sustainable yield of winter wheat the dose of mineral fertilizers should be increased and nitrogen - up to 140 kg per hectare. The increase in yield is due the rise of the quantity of grains per ear and weight of grain per ear
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
The article discusses the effect of additional spikelets
in the variety of Bezostaya 1 on the realization of
productivity of the examined plants. We traced the
frequency of occurrence of multirov spikes and studied
the effect of this phenomenon on the productivity and
the main quantitative characteristics of the studied
plants. The article demonstrates the structure
distinction of productivity for abnormal and normal
ears. Experience was one-way vegetation, planted in
triplicate, time of experiment - 2013 - 2015 years.
The study revealed that the most frequent was the
emergence of 1-4 additional spikelets per spike. Some
quantitative characters had a slight deviation, these
include the number of spiked ledges on the kernek,
spike length and plant height. To a large extent we
increased the characteristic values such as the number
of grains per ear, number of spikelets per spike,
number of grains onto the ledge, head weight and the
weight of grains spike. We significantly reduced
weight of 1000 grains. It was revealed that more
localized spikes were mostly in the middle, the most
productive part of the ear. As a result, changes have
affected not only the quantitative characteristics
related to the productivity of the ear, but also its
architectonic whole
Remineralization of leached chernozem was carried
out by applying such rocks as loess-like loam, shell
limestone, apatite phosphogypsum. We have
revealed that the introduction of species didn’t
change substantially the content of boron during the
growing season. We have also displayed the seasonal
dynamics of macro variants of the experiment and
the increase in the content of food items in the phase
of active growth of winter wheat. Seasonal dynamics
of trace elements is expressed, but can not be
expressed with certain regularity
