Increasing the productivity of agricultural plants,
including rice, is the most important area of breeding.
The creation of varieties with vertically leaved
architectonics allows to have a qualitative approach
not only to the process of formation of a highly
productive agrocenosis, but also to solve questions of
assessing the productivity of rice. To create highly
productive varieties, it is necessary to develop new,
more efficient methods of selection
The researches of the quality of 34 donor cows estrus
detection during superovulation induction period, after
Pg F2α injections were carried out. The clinical heat
index was set up and applied. The clinical heat index
is clinical prognostic criterion of successfulness of
superovulation induction and embryo productivity. It
was shown that donor cows showing signs of oestrus
during 48-72 hours after Pg F2α injections had the
best embryo collection qualities while certain increase
of degenerated or aborted embryos and unfertilized
oocytes is determined in embryo collections from
cows showing signs of oestrus before or after that
period
The article contains data on results of calving and blood tests of heifers moved from the Astrakhan region in the Temryuk district of the Krasnodar region in the condition of early pregnancy. According to the accompanying documents, cell blood count, hemoglobin and biochemical parameters were consistent with species and age normal. Calving took place without complications and did not require delivery; received 36 of 36 calves from cows. The quality of the calves found to be satisfactory. On the 45th day of service period, clinical signs of impaired health status were present in 2 animals, however biochemical markers of liver disease, inflammation, and anemia was identified in 7 heifers. In the context of work on creation of livestock combined milk and meat productivity of inseminated heifers and heifers of the Simmental breed the Simmental semen (25 cows) and Aberdeen Angus (34 cows) breeds. Fruitfully inseminated 55 out of 60 animals; indicator of severity of calving was 8 % for Simmental cows. Calves of Simmental breed and Simmental-Aberdeen Angus cross-breeds meet the requirements for live weight at birth and the exterior. Farming on the formation of herds of milk and meat direction of productivity are found to be effective
In the current economic conditions of the import
substitution, special importance is given to the
search for new feed sources, methods of preparing
them for feeding, the use of biologically active
substances and enzymes. At the forefront of feed
production is rape as breeding work with this
culture has showed positive results. Currently,
selectionists have bred yellow double-zero "00"
varieties of rapeseeds free of erucic acid of
"Canole" type, that have low glucosinolate level.
The development of new and modern technology
standards are required for preparation them for
feeding, since they are fundamentally different
from the previously used rapeseed varieties and
have fewer restrictions for feeding to different
types of farm animals and poultry. The article
presents a fairly lengthy and reasoned review of the
literature of a large number of authors on the topic,
as well as given rapeseed market analysis, rational
and advanced methods of preparing rapeseed
processed products for feeding to young and adult
animals. Much attention is paid to the use of a
variety of biologically active substances and
enzymes, which improve digestion and absorption
of nutrients from rations with rapeseed
processingproducts, increase productivity and
reduce feed costs per unit of production. The use of
processing products of rapeseed improves the
profitability of livestock production. Feeding of
rapeseedcake to cattle increases the protein content
and volatile fatty acids in the rumen content,
increases the number of infusoria and decreases
ammonia levels. The inclusion of rape forage in
diets of farm animals and poultry improves
hematological parameters. Products of rapeseed
processing of the varieties with low
glucosinolatesa1re recommended for the rations of
farm animals and poultry depending on the species,
age and physiological state
Duration of vegetation period is one of the main
adaptive traits for any crop or variety. Reasonability
of cultivation of a variety in a particular soil and
climate zone is determined by the duration of the
vegetative period. One of the aims of breeding is
the creation of the varieties with the main vegetative
phases lasting at more favorable climatic conditions.
The most accurate way to determine maturity
group of a variety is by estimation of starting
of heading phase, which can be defined with the
greatest precision. The article covers the analysis of
the duration of the vegetative period of the lines
and varieties of winter barley of local and foreign
selection in the central zone of Krasnodar region.
All the varieties were divided into three maturity
groups. The vegetative periods of the varieties were
studied during four years. The most favorable and
adverse conditions for yield formation were determined.
The interactions between the productivity of
the varieties depending on maturity group were
identified. The varieties of the early maturity group
which are more productive than the check were
selected, which is most valuable for the breeding of
the crop. The best varieties with the high and stable
yield and the positive traits are regularly involved
in the breeding programs with the porpoise of making
new varieties of the winter barley
Elements of the cultivation technology of winter wheat variety called ‘Antonina’ with the application of different backgrounds of soil fertility, norms of fertilizers, system of plant protection from weeds, pests and diseases were studied. The studies are conducted in a polyfactorial stationary experiment: factor A - soil fertility; factor B - system of fertilizers; factor C - plant protection system; factor D - methods of basic soil cultivation. In the experiment four models of soil fertility levels were studied: А0 - the initial (natural background); А1 - average (200 kg / ha Р2О5 and 200 t / ha of litter manure); А2 - increased (doses are doubled); when А3 - high (tripled). Based on the studies it has been established that to obtain a stable yield of winter wheat, an increased dose of mineral fertilizers should be used, which also ensures high grain quality indicators. The maximum yield increase of 37% was achieved on varieties in comparison with extensive technology. A significant increase of the protein content in the grain from 12.8 to 15.3% and gluten from 22.0 to 27.8% was found in the intensive technology - triple doses of fertilizers (NPK) and the use of integrated protection against diseases, pests and weeds. The introduction of high doses of mineral fertilizers contributes to the accumulation in the soil and grain of nitrogen, and also reduces the content of copper and zinc
DYNAMICS OF CATALASE ACTIVITY IN THE LEAVES OF APPLE TREES UNDER THE INFLUENCE OF FOLIAR FERTILIZING
The research was conducted studying the effect of
various system of foliar fertigation on catalase activity
in the apple orchard with drip irrigation in 2013-2014.
The object of research were apple trees of
Zhigulevskoye variety grafted on rootstock 62-396 in
experimental intensive apple orchard of I.V. Michurin
FSC which had been planted in 2007. During
vegetation, the following indices were determined in
apple tree leaves in dynamics: catalase activity by
gasometrical method of M.I Lishkevich on the 3rd and
5
th day after treatments, the content of nitrogen
(Kjeldahl method), phosphorus (KFK-3), potassium
and calcium (Jenway PFP-7). Data were statistical
processed according to the generally accepted methods
described by B.A. Dospekhov. It has been established
that foliar fertigation increased catalase activity on the
3
rd day after treatment, which then decreases to normal
values. So, treatments acted as a stress factor.
Correlation of catalase activity with nitrogen content in
the leaves increased, and with calcium content
decreased as the number of megafol mixed with
calcium calbit treatments was enlarged. Using tank
mixtures for multiple treatments with combination of
antistress preparations and calcium-containing
agrochemicals allows to moderate significantly the
stress effect of foliar fertilizing on plants
A fundamental element of the technology is the use
of beef cattle in the economic purposes of biological
resources of animals. In the development of modern
technologies there is a lack of focusing on one of the
main features of cattle – its own perception of the
environment, that is panoramic (binocular) vision. In
the modern cattle breeding we focuse on the
development of a variety of exterior signs. However,
one of the indicators that affect the behavioral
responses of animals (the degree of development of
the muzzle and the forehead of the animal, the shape
of the head) does not have due importance. The
author has conducted its degree of development
studies in bulls and cows of different breeds. Along
the length of the head, meat breeds (Hereford,
Aberdeen Angus, Simmental, Charolais) gave way to
Red Steppe 14.9; 15.5; 5.5 and 5.0 cm (27,5; 28,6;
10,1 and 9,2%, P
The article has considered the influence of modern
climate changes on the intensity of erosion processes
within the boundaries of the basic landscapes of the
region. It has given the results of the spatial
distribution of the rainfalls. The most noticeable
climate changes of the Bryansk region are reflected in
the decrease in the activity of erosion during snowmelt
due to the lower amounts of snow and soil frost depth.
In the area, the dynamics of rainfall does not detect a
single trend. The processes of erosion and deflation are
studied in the relationship, the manifestation of these
processes on the territory of the Bryansk region. It has
published the results of the risk analysis of erosion and
deflation on forest soils of the region and justified the
application of G. V. Bastrakov’s method for
modeling erosion-resistant agricultural landscapes.
This approach has a number of advantages over the
other known methods. In our case, regardless of soil
and climatic and geomorphological conditions, the
challenge is to ensure such events in which erosion
resistance of the land will not be below a critical value.
The research results are the initial data in designing
soil conservation activities on the territory of the
Bryansk region. The obtained data of the erosive
properties of soils from climatic changes enable the
study and forecasting of the development of
agricultural landscapes of the region in the medium
term
The article reviews the results of studying the influence
of mineral fertilizers on the qualitative indices of the
Merlot grape variety in the Anapo-Taman zone of the
Krasnodar region. The technology of cultivation of
grapes on the experimental plot was in accordance with
the accepted for the given zone and culture.
Agrobiological work was carried out at the optimal
time and had a high quality of execution. Grape bushes
are laid in a 3.0 x 2.0 m pattern. Formation - a twoshoulder
horizontal cordon. On the bushes we formed
the same load of shoots and bunches. Scheme of the
experiment: option 1 – no fertilizers (control); option
2-superphosphate with a mixture of potassium salt
(P90K90) from the autumn; option 3 –nitroammofoska
(N120P120K120) from autumn; option 4 – ammonium
nitrate (N60) in early spring. Analysis of the results of
studies on the study of biological features of growth,
fruiting, yield and quality of Merlot grape varieties on the background of the use of mineral fertilizers shows
their high efficiency in the conditions of the AnapoTamanskaya
zone of the Krasnodar region and can be
recommended for use in production conditions.
Mineral fertilizers ensures the receipt of dry bulk wine
of superior quality control sample (without fertilizers)
