The article presents the material of forecasting for grape
yield of next year and establishing the optimal loading if
cutting of bushes. The material includes 14 varieties of
grapes, 11 of them are technical and 3 are table ones. For
each year of stable high yield of grapes, it is necessary to
pre-set the optimum length of fruit cutting of shoots and
optimum load on the bush healthy eyes. To do this for
each variety on the eve of trimming bushes we perform
optimum productivity analysis of wintering buds of fruit
along the length of shoots, i.e. we implement forecasting
of grape yield for next year. We have a plan of forecasting
for yields of vineyards by microscopy of wintering
buds on one-year shoots of fruit ripened grapes in order
to establish the potential of embryonic establishment of
inflorescences in the central holes of buds. Based on the
analysis of buds, the indices were calculated for wintering
fruiting buds and their degree of damage during the
growing season. It was revealed, that the majority of
grape varieties under study shows high tab embryonic
inflorescences in central buds in overwintering buds for
next year yield. Higher rates at a rate of fruiting buds
were wintering in the varieties: Moldova (section 27). -
1.66; Bianca (section 6). - 1.83; Kunlean (section 15). -
1.71; Merlot (section 14). - 1.64; Saperavi (section 56). -
1.76. The lowest rates of fructification - the varieties
Muscat Hamburg (section 21) and Augustine (section
11) and were respectively 1.20 and 1.24. As a planned
productivity, we offered the optimal loading model of
cutting bushes buds. As a result of productivity analyzes
of buds along the length of the fruit shoots in 2016 we
recommended to carry out pruning of fruit annual shoots
3-4 buds of the form of AZOS-1 and the form of cordon
- 5-6 buds
There are given the results of long-term research of different forms of soil nitrogen content and their relationships with the content of total nitrogen in leaves and yield. It was detected a strong positive correlation among them hydrolyzable nitrogen content in the soil and total nitrogen content in the leaves and yield. It is proposed the use of this index for diagnostic of soil nitrogen supply
The article presents results of studying the oenology
and the biochemistry of the Cabernet-Sauvignon
grapes in different areas of the Krasnodar region -
Taman, Anapa, Abrau-Dyurso, Gelendzhik and
Krasnodar. The yields, the mechanical composition of
the grapes, the biochemical indicators of the juice of
berries were compared. The cultivation zone affects
the yield, the average mass of the bunch, the number
and mass of berries in the bunch, the mass of the crest,
but according to the percentage of berries and crest in
the bunch, the bunch structure (ratio of mass of berries
to mass of the ridge) does not significantly differ
between growing zones. The mass of 100 berries and
100 seeds, the weight of seeds in 100 berries, the
clustering index (the ratio of pulp with juice to peel)
can differ in different places of growth, but with
insignificant coefficients of variation. The composition
of the bunch as a percentage of the total mass varies
little over the growing zones: the ridges make up 5.6-
5.7%, the skin 4.9-5.2%, the seeds 4.8-4.9%, the pulp
with the juice - 84.3-84.5%. Structural and berry
indicators varied in the range of 5.4-5.5 and 76.84,
respectively. Depending on the place of cultivation, the
yield of the grape must in laboratory conditions was
75.1-75.7%. Analysis of the structure, composition and
the structure of bunches showed that the mechanical
composition of Cabernet-Sauvignon refers to the first
group of varieties that retain their valuable
characteristics when changing the growing conditions.
When harvesting, the mass concentration of sugars was
19-19.8%, titrated acidity - 8.1-9.2 g / dm3, pH - 3.3-
3.4. Depending on the place of cultivation of the
content of organic acids in the juice of berries was:
wine - 4917-5918 mg / dm3, apple - 1926-2763, lemon
- 215-416 mg / dm3. In different places of cultivation
in% of the total amount of organic acids studied, the
content of tartaric acid varied from 61.7 to 71.4%,
apple - from 24.7 to 33.3%, lemon - from 3 to 5%.
Thus, the content of organic acids in the juice of
Cabernet-Sauvignon berries depends on the specific
growing conditions. Depending on the growing places,
the mass concentration of potassium cations is 2630-3508 mg / dm3, sodium 162-436, magnesium 171-230,
calcium 185-255 mg / dm3. However, in most cases,
as a percentage of the total cation content, there are no
differences depending on the site of growth. Thus, the
biochemical parameters of the juice of CabernetSauvignon
berries depend on the specific natural
conditions of the terrain and, according to these
parameters, the variety belongs to the second group of
varieties with less plasticity to different growing
conditions
The purpose of the research is to assess the ability of reclamation plantations of walnut and black nut on the accumulation of heavy metals in their phytomass – leaves, shoots, and fruit. The studies were conducted in the Rostov region, the Krasnodar and the Stavropol regions. In the samples of vegetative aboveground and soil (under the canopy nuts) we have defined qualitative content of total forms of heavy metals of Cu, Ni, Co, Zn, Mn, Pb, Cd, Cr. This ability is the accumulation of heavy metals in leaves, shoots and fruit that fall from the atmosphere. Later, the bulk forms of these metals with the annual litter come to litter, and then – into the soil
In recent years, due to the increasing aridity there was
an increase in the frequency of epiphytoties leaf disease
of barley. Therefore, we can see now how greatly
increased the need for the creation of resistant grades.
Introduction of the selection marker will significantly
speed up the breeding process for resistance to
pathogens. Employees of the All-Russian Institute of
Plant Protection recommended three genes - Rpt 1b,
Rpt 5, Rpt 6 to control the resistance to the pathogen
Pyrenophora teres for use in breeding programs in the
North Caucasus. Rpt 5 gene is one of the most efficient
one, because it determines the resistance to the eight
isolates of the fungus Pyrenophora teres of different
origin. In 2011, Australian scientists have discovered
microsatellite markers called Bmag0173 and HVM74,
closely linked to the gene Rpt5, which are used very
effectively in order to marker-assisted selection of
resistant grades in Australia and Canada. Due to the
urgency of creating new genotypes carrying resistance
genes to net blotch, that would be effective in the
Southern Federal Region, the staff of All-Russian
Scientific-research institute of Grain Crops after I.G.
Kalinenko and the All-Russian Research Institute of
Plant after N.I. Vavilov has developed a practical
strategy for the use of molecular techniques to create
barley grades resistant to this pathogen, which is being
successfully implemented
In the article we have developed and studied feed additives in broiler diets based on natural montmorillonite varieties. Biological effect of Ekobentokorm additives due to their mineral composition and adsorption properties because of the big nano-pores and vitamin-mineral adsorption feed additive (WMACD), additionally, the effect has been included in its composition of biologically active substances. Effect of use of Ekobentokorm sorbent additives in feed for broilers and vitamin-mineral adsorption feed additives (WMACD) contributed to the increase of meat productivity, preservation of poultry, eating and feed conversion, the improving the carcasses
The article presents the studies that were conducted in 2011-2014 agricultural years in the experimental rotation hospital departments of Agriculture and Agricultural Chemistry, located in the Experimental Station of Stavropol State Agrarian University. The hospital is part of a geographical network experiments with fertilizers and registered in the register of long experience certificates of GeoNetwork VNIIA of the Russian Federation. We have presented an influence of systems of fertilizers and tillage practices on yield, indicators of the structure and quality characteristics of winter wheat of Zustrich varieties grown after pea predecessor in a stationary experience of Stavropol GAU. The influence of fertilization systems built on different principles on the productivity of winter wheat after pea predecessor in the area of unstable moistening was studied. The article has practical significance, since on the basis of the research we have found experimental evidences to recommend a cash-balance method for determining fertilization rates for the construction of the settlement system of fertilizers, to assure maximum efficiency and provide a level of skill programming yield 90-100%. We have also offered low-cost bio- fertilizers in crop rotation system, based on the efficient use of organic fertilizers, local application of minimal doses of mineral fertilizers
Based on the analysis of the nature of some
flowering test crosses which have been resulted in
the hybridization with purposely chosen sterile
sources (analyzers), the new self - pollinated lines
of maize have been identified according to the
content of fertility-restorer genes of ‘C’ type of
CMS. Genotype of the line RD 257 -
rf4rf4rf5rf5Ff6Rf6 (class II), genotype of the line RD
245 - rf4 rf4 Rf5 Rf5 rf6 rf6 (class III), genotype of
the line RD 274 - rf4rf4Rf5Rf5Rf6Rf6 (class V),
genotype of the line RD 231 - Rf4Rf4rf5rf5Rf6Rf6
(class VI ) genotype of the line RD 261 -
Rf4Rf4Rf5Rf5Rf6Rf6 (class VII). The identification
of the content of the alleles of fertility - restorer
genes allows forecasting the nature of flowering
hybrid progeny resulted in the hybridization with a
known genotype. We have created a catalog of self
- pollinated lines of maize according to the fertilityrestorer
genes, which consists of 18 lines, which
have been studied in all the years of research. We
have identified the lines belonging to classes I, II,
III, V, VI, VII and VIII. During the transfer of
maize hybrids on a sterile basis the lines of classes I
and VIII are those ones which have been of great
interest. The self - pollinated lines KV 204, SP 286
(class I) are the reliable fixers of «C» type of CMS.
The progeny resulted in the hybridization with any
sterile lines is characterized by complete sterility.
The new self - pollinated lines KV 498, KV 272,
KV 227, SP 357, RD 261 (class VIII) are constant
natural fertility-restorers. They are able to fully
restore fertility in hybridization with any sterile
lines and in any growing conditions

Development of confectionery sunflower openpollinated
varieties (OP-varieties) is a prospect
direction in sunflower breeding. High price level
for confectionery sunflower seeds pushes forward
the breeding program. Contrary, it is necessary to
offer product, meeting consumer’s expectation for
large seeds, good dehulling rate, proper oil and
husk content. The aim of our work is to study
morphometric peculiarities of seed structure for
sunflower OP-varieties of different types – oil and
confectionery, and to identify the best samples for
using in the breeding program as an initial material.
The study was done at All-Russia Oil Crops
Research Institute (VNIIMK) named by V.S.
Pustovoit (Krasnodar) in 2014 and 2015. Seeds of
6 OP sunflower varieties of VNIIMK breeding
were used as a material (confectionery type –
Dzhinn, SPK, Lakomka, Oreshek, Borodinskiy and
oil-type – Muster). OP-varieties were sown by
randomized blocks with 3 replications. Every plot
had 4 rows. It was shown that seeds of
confectionery sunflower OP-varieties had higher
values of main traits (length, width and thickness)
in comparison with oil-type sunflower. Seed traits
analyses allowed identifying the best confectionery
samples (Dzhinn and Oreshek) for future breeding
