This article is devoted to studying the influence of
conditions of keeping and feedings on broilers of Hubbard
RedBro cross, and the quality of the received
products in case of application of floor and cellular
content in the conditions of a farm. It was found that
when receiving a feed of its own production with the
use of feed ingredients grown in farms without pesticides,
recorded a statistically significant reduction in
the potentially dangerous health animal substances. As
compared with a factory forage therein reduced pesticide
content by 14 times, mercury and arsenic is 24
times, 5 times cadmium, lead 10 times. Results of
studying of economic indicators of cultivation of
broilers of cross Hubbard RedBro and also chemical
composition and quality of carcasses demonstrated that
the essential difference between a floor and cellular
condition of keeping is not established, however use of
a diet on the basis of what forages promoted statistically
reliable decrease in concentration of toxic metals in
muscles of a bird of experienced groups. As a result it
was found that use of the researched compound feed in
diets of broilers raised indicators of biosafety and provided
ecologically safe (“organic”) meat products of
poultry farming
The use of physical factors for preplant stimulation
of seeds increases vigor, germination and improves
the yield of agricultural products. One of the effective
ways to improve seed grain quality is to impact
on the seeds using physical factors, in particular, an
alternating electromagnetic field of industrial frequency
of 50 Hz (EMF of IF of 50 Hz). We studied
the impact of EMF of IF of 50 Hz on the energy
germination of mid-ripening spring barley seeds of
promising varieties Vakula, Vikont, Ratnik. Carrying
out the experimental studies we used a laboratory
setup with annular pole points of rectangular
cross section. Our disperse analysis resulted in data
on germinative energy of seeds of spring barley
varieties Vakula, Vikont, Ratnik, which showed that
while treating seeds of spring barley by an alternating
electromagnetic field of industrial frequency of
50Hz, we obtained the best values of germinative
energy of seeds of Variety Vikont with a mode of
processing being equal to W = 16%, T = 2 c, L =
0,03 m
Barley is one of the important fodder crops. In modern
Russia barley is sown throughout the farming areas.
The effectiveness of barley cultivation in some years is
reduced due to the infestation with helminthosporiosis.
Net blotch of barley Drechslera teres is a widespread
and highly destructive disease in the world including
Russia. In recent years the disease has been
progressing in all grain-producing countries. Yield
reduction due to the strong development of the blotch
can reach up to 45%. Most cultivated barley varieties
are susceptible to Drechslera teres. Нelminthosporiosis
are characterized by greater variability and rapid
adaptation to new varieties of host plants. In order to
solve successfully the problem of barley immunity to
net blotch it’s necessary to conduct genetics and
population studies of the Hordeum vulgare -
Drechslera teres pathosystem
Тhe results of the evaluation of the condition of trees

For the research period (2003-2016), 57 pest species
and 46 pathogens were recorded on stone and
pomaceous fruits in humid Russian subtropics,
among which the representatives of the order
Lepidoptera and the division Ascomycota
predominate. The greatest number of the species was
recorded on the apple tree - 35 pests and 25
pathogens, the smallest - on cherry and sweet cherry
trees (13 and 10, respectively). 43,7 per cent of the
species are polyphages, while the relative abundance
of monophages among fungi is higher than among
arthropods. The species with activity in the summer
are prevalent. A group of species that are harmful in
humid subtropical environments all year round (11
species of phytophages and 19 pathogens) was
identified. Analyzing the changes in the species
composition of the complex through the time, we can
speak about the relative stability of the dominant
species. The group of the typical dominant species of
pests for almost a century has included Grapholita
molesta Busck., G. funebrana Tr., Cydia pomonella
L., Taphrina deformans (Berk.) Tul., Stigmina
carpophila (Lév.) M.B. Ellis, Monilinia laxa (Aderh.
et Ruhland) Honey, M. fructigena Honey,
Podosphaera leucotricha (Ellis & Everh.) E.S.
Salmon, Venturia carpophila E.E. Fisher and pear
V. pyrina Aderh. Eriosoma lanigerum Hausm.,
Scolytus mali Bechst. and Tranzschelia prunispinosae
(Pers.) Dietel are currently dropped out
from the group of the dominants; Halyomorpha halys
Stål, which is a new pest for Russia, was added.
Groups of the species with sharp fluctuations in
abundance or frequently encountered were
distinguished
This article deals with the results of the research work
concerning the influence of foliar application of grape
of Saperavi variety by soluble fertilizers of new
generation-Nutrivant plus and Kelik potassiumsilicon.
The influence of these fertilizers on yield and
actual fruitfulness have also been investigated. The
experiments have been carried out both in pureform
and in a tankmixture with growth regulator
“VIMPEL”. The treatment by these fertilizers has
been done three times in the following period; after
flowering, in fruit growth phase,(pea-size berry) and
in the phase of fruit maturing The foliar treatment in a
pure form as well as in a tank mixture led to increase
of bunch weight, harvest per bush and the yield
capacity of plantation. The influence of fertilizers
depended not only on variants of experiment but also
on weather conditions of the previous and current year
as well as on the previous yield. The negative
correlation between the indexes of yield structure of
the previous year and the actual fruitfulness of the
current year has been revealed. However, the character
of these correlative connections depends on many
factors and greatly differs according to the year. As a
result of these investigations, it was stated that foliar
application of Saperavi grape variety by fertilizers of a
new generation Nutrivant plus and Kelik potassiumsilicon
in a tank mixture with growth regulator
“Vimpel” in periods after flowering, berry
growth(pea-size berry) and at the beginning of berry
maturing did not promote a stable and significant
increase of the main indexes of an actual fruitfulness. The real increase observed in all experimental variants
was achieved mainly due to the increase of the
average weight of the bunch
The article presents the results of evaluation of 20
strawberry hybrids by breeding in the NCRRIHV on
the traits of productivity and chemical composition of
berries. The results of the grouping of studied hybrids
at the number of berries per plant and average weight
of berries were shown. We have also highlighted the
best hybrids, that shows the maximum number of berries
(pcs per plant) – 2-10-06 Firework × Honey, 5-2-
06 Primella × Marmolada and average weight of berries
(g) - 5-1-12 Elsanta × Alba, 11-7-06 Molling Pandora
× Marmolada, 7-1-12 Elsanta × Camarosa, 6-1-06
Vesnyanka × Primella, 2-4-12 Eros × Camarosa, 3-4-
12 Belrubi × Camarosa. It was found that the integrated
combination of high productivity characteristic values
(the number of berries per plant and average
weight of berries) are not mentioned in any of the hybrid
selections. Study of the traits of berries quality in
strawberry hybrids showed that they contain from 6,3
to 11,4% soluble solids, from 4,8 to 8,6% sugar, from
0,62 to 1,30% acid, the sugar-acid ratio It varies from
4,0 to 8,8 relative units. Almost all the studied hybrids
accumulate in the berries more vitamin C in comparison
with the control variety Honey. According to the
complex biochemical parameters highlighted hybrids

During 2012-2015 from the two fissile populations
of rice hybrid Il.14 x Kuboyar and Il.28 x Kuboya
we conducted multidirectional selection of panicles
with low, medium and high number of grains in
them. It was established a different reaction to the
selection of hybrid generations by yield. The lowest
yield was formed at planting grain from small panicles,
intermediate - from the middle panicles and
biggest - from the major panicles. The reaction to
selection decreased with each successive generation.
In the hybrid Il.14 x Kuboyar at positive selection of
the yield increase towards the initial population F2
was in F3 - 10,5%, in the F4 - 3,8% and F5 - 1,9%, at
Il.28 x Kuboyar - respectively 4, 4%, 3.1% and
0.7%. At negative selection in Il.14 x Kuboyar there
was a decrease of yield on 7.7% F3, in F4 on 6.9%
and in F5 on 0.2%. By years of research was not observed
variations in grain yield obtained from the
panicle with an average grainness and generally was
at the level of the original population. At the hybrid
Il.28 x Kuboyar for negative selection of the relative
yield initially decreased on 1.7% in F3, while then for
all kinds of selection to the fifth generation grew up
and different to a lesser extent than the first the hybrid,
although the ranks of the values preserved. The
yield from a fraction of well-grained was 98.4%,
medium grained - 96.5%, low grained - 94.2% of the
initial Kuboyar variety

Newton, RIC 345 and Eric), as well as early-middle
middle Rossiyskaya 1 from the change of average daily
air temperature at different dates of sowing and preplant
seed treatment by the preparation "TMTD-plus"
containing the growth promoter called Krezatsin in its
composition. The studies were conducted in
accordance with the thematic plan of scientific
researches of the department of crop and forage
production of Stavropol State Agrarian University. The
technology of maize growing on the experimental plot
corresponds to the standard technology for this area
and culture. The sowing was performed in three stages.
The first (early) sowing period was at t = + 7 ... +8 ° C.
The second (recommended) – was at t = + 10 ... + 12 °
C. The third (later) sowing period was carried out at t
= +15 ° C. There was identified a high inverse
correlation between the average daily air temperature
and the duration of the intraphase periods of maize
propagation. Thus, at the shifting of maize sowing
dates with the second half of may on the second half of
April, the optimization of heat regime in the generative
period and rising of efficiency of use of thermal of
resources of the region. There was marked the
acceleration of development of corn seedlings when
the average daily air temperatures was up to +12 ° C

In this article we present information on features of
microcloning in culture of in vitro of perspective for
Eurasia, pink and white-berry table genetic grades of
grapes by I. A. Kostrikin, V. N. Kraynov and V. V.
Zagorulko. Researches were conducted at an input
stage in culture of in vitro of meristems of 0,1-0,2 mm
in size. At the majority of grades and forms, we noted
good regeneration abilities in the conditions of sterile
culture. It is bound to the fact that almost all the
studied grades: Anyuta, Bogatyanovsky, the Princess
Olga, Preobrazhenie, Anniversary of Novocherkassk,
Favor are received from crossing of couple the Mascot
× Sultana-ray grape. And only grades called Libya and
Lowland which showed lower regeneration properties
at stages of proliferation and rooting of shoots are
received from crossing the couple of Flamingo ×
Arkadya and (Talisman x Tomaysky) respectively. At
the same time, the grade of Talisman, being one of the
parents of the majority of the studied grades, showed
stable results at all stages of cultivation
