The article presents the research results of the impact of amendment improving soil structure on soil upon sprinkler irrigation of agricultural lands. It is proposed to use artificial aggregation of soil for water erosion control via composition of structure-forming materials. The developed composition includes slagheap rock, bentonitic clay, claydite screenings, and shell limestone. Adjusted analytical relations of the impact of the amendment on runoff coefficient depending on the intensity of artificial rain upon irrigation of agricultural lands, slope, and water permeability have been revealed. Regression analysis of spectral surfaces has shown that slope of irrigation site has a significant impact on the increasing of runoff coefficient values, while correlation coefficient equals to 0.97. Water permeability has negative correlation, -0.85, with increasing the values of runoff coefficient. The relation between runoff coefficient and intensity of artificial rain is less strong, 0.89. We have determined that applying of the given amendment provides decreasing of runoff coefficient by 15 % depending on the slope of irrigation site, and by 20 % depending on rain intensity. Experts in the field of land reclamation can use obtained analytical relations for predicting surface soil loss when estimating the efficiency of amendment applying to control soil erosion activities at agricultural lands
The article presents results of the assessment of the
efficiency of non-hormonal preparations which were
not earlier applied in culture in vitro with high physiological
activity (the preparations received by production
of furfural, and also derivatives and compositions
of organic acids) during regenerations of microshoots
of plum, comparison of their influence with
influence of growth regulators which are traditionally
used in clonal micropropagation. These experimental
preparations were received when processing waste of
agricultural production. In this work we used: technology
of clonal micropropagation of plants of in
vitro, statistical data processing by method of the
dispersive analysis. The objects of researches were
microshoots of plum of a Stanley variety. We have
established that on mediums with the preparations
"Universal", sodium succinate, potassium succinate,
amber acid, L-1 the large, intensively colored plum
microshoots develop surpassing control (medium
with BAP of 1 mg/l, IBA of 0,1 mg/l, gibberellic acid
of 0,5 mg/l) in morphometric parameters. Thus, the
preparations "Universal", sodium succinate, potassium
succinate, amber acid, L-1 in concentration of 4,0
mg/l proved as the growth factors which are favorably
influencing on plantlets’ regeneration and a qualitative
condition of microshoots of plum
The article presents the results of studying the effect of
different lengths of fruit vines with the same load
wintering buds of bushes on the yield and quality of
Moldova grapes. It was found that the biological
indicators of fruiting Moldova grapes improved by
lengthening fruit vines, taking into account weather
conditions. Shortening the vines increases germination
and fruitfulness degree base buds and reserve buds.
Productivity is increased by lengthening fruit vines. It
is determined by the degree of fruitfulness buds of the
vine, the development of floscules of wintering buds,
bunch and berries weight, number of berries in
bunches. The optimum is pruning vines to 10-12 buds.
Harmonious taste, weight of bunches and berries,
transportability factor fixed high yield of grapes
standard (85,6-86,4%) with different length of fruit
vines. The highest productivity of leaves makes
pruning fruit vines to 10-12 buds. The strength of
shoot growth and volume growth of bushes reduced at
an elongation of the fruit vines. The more moderate
growth of shoots observed at long (10-12 buds)
pruning vines. There is no significant difference to the
degree of maturation of shoots with different length
vines. In order to increase the yield of Moldova grapes
in the central zone of the Krasnodar region expedient
cut fruit vines to 10-12 buds
In the article we show the results of studying the influence of Ecoss enriched biogumat on the photosynthetic complex of radish plants. Seed treatment with humate allows plants to form more powerful root system and develop resistance to various diseases, they are less affected root and basal rot. Plants form a large leaf surface. In leaves we have increased chlorophyll content, they remain longer green, more intense and will accumulate in vegetation greater number of assimilant (carbohydrates), and ultimately increase the yield. More intensive work of the leaves apparatus also contributes to the reduction of nitrates in the production, which is especially important when growing vegetables, melons and potatoes. Humates have a positive impact on yields on soils of different fertility and the different value of the yield. This not only increases the yield of 3 - 5 kg/ha, but also increases the gluten content in grain of winter wheat by 3 - 4%. The application of humates has a high adaptability. Their use can be combined with seed treatment pesticides, spraying crops with pesticides, mineral fertilizers. Therefore, humates are widely spread not only in Russia but all over the world. We have studied the content of chlorophylls and carotenoids at leaf apparatus of radish plants, depending on the methods and doses of the processing with humic preparation
In the modern wine growing, for fighting against root
phylloxera an inoculation of European-Asian grapes
varieties on rootstocks steady against this wrecker is
used. In this article we present the information about
the types of rootstocks of domestic and foreign
breeding used in the modern branch of wine
growing. The area of their use is described; the
useful properties of rootstocks and their demerits are
highlighted. The purpose of this work is creating new
grapes rootstocks which wouldn't have the merits of
existing rootstocks. The short description of the
grapes rootstocks which were created in the Anapa
Zonal Experimental Station of wine growing and
winemaking such as AZOS-1, AZOS-2, AZOS-3,
AZOS-4, AZOS-5 and AZOS-6 is given in the
article. It is indicated that these rootstocks have a
high resistance to a leaf form of phylloxera, to
chlorosis and to some other diseases of a grapes
bush. They have the short period of vegetation, high
quantity of standard cutting from hectare and other
useful properties. In the article the description of a
new formation of rootstocks grapes bushes of "AOS-
1" and "AOS-2" with a free trail shoots is given. This
construction of grapes bush is developed by the
Anapa's Zonal Experimental Station of wine growing
and winemaking. We have also given all the
advantages of this forming in comparison with other
designs of grapes bushes. It is especially noted that
use of this forming of bushes increases the
productivity per men in the process of bushes scrap
and preparation of cutting; the expenditures on the
struggle against diseases and wreckers on the vineyards are reduced; the quantity standard of
grapes cutting increases by 27-33%
The article gives the results of the study of the texture
of the grapes and biochemical characteristics of red
wine grape varieties of Cabernet Sauvignon, Cabernet
Franc, Merlot, Sapeari, Tsimladar, Pinot Noir for the
production of juice of direct extraction and blending.
The studied varieties in terms of the structure of the
cluster may be divided into three groups of blackpinene
(21.1), Cabernet Franc and Tsimladar (18.7 -
17.5), Cabernet Sauvignon, Merlot, Saperavi (16.5 -
16.8) , and bunches of addition in terms of two groups
- Tsimladar (17.6), Cabernet - Sauvignon and other
(15.6 - 16.4). The structural component of grapes varieties
ranged from 5.2 to 5.9, berry index - from 62.1 to
83.4, the output of the wort from 74.2 to 76.3%. The
content of sugars and acids in the berries of all varieties
is favorable for the production of beverages. The
largest Tartaric acid content was found in the juice of
the varieties of Cabernet Sauvignon, Pinot Black,
malic acid - in the juice of varieties Saperavi, Merlot,
Tsimladar, citric acid - in the juice Tsimladar varieties,
Cabernet Sauvignon, Saperavi. The ratio of tartaric
acid to the content of the apple juice Cabernet Sauvignon
was 2.9: 1, Cabernet Franc 2.6: 1, Pinot Black
2.5: 1, Merlot and Tsimladar 1.6: 1, 1.1 Sapevari: 1.
According to the content of potassium cations, sodium,
magnesium and calcium there were chosen three varieties
of Cabernet Sauvignon and Cabernet Franc. The
lowest content of potassium and magnesium cations
was in the variety of Tsimladar, Sodium – in the varieties
Merlot and Saperavi, calcium – in Saperavi. Excellent
tasting commended for juices was given to
Cabernet Sauvignon, Saperavi, Tsimladar, good – to
Cabernet Franc, Merlot, Pinot black. Best blending
juice obtained by mixing the juice of the grape of the
varieties of Cabernet Sauvignon and Pinot black
70:30, Saperavi and Pinot black 50:50. From the
grapes of produced varieties, we can produce juice and varietal by name ampelographic variety and blended to
extend the range

The features of seeding and vegetative reproduction of
Hibiscus Syrian (Hibiscus syriacus L.) in the South
regions of Russia are accounted in the article. It is
shown that the not sorted Hibiscuses reproduce better
by seeds. Sowing is made before winter (November).
The young growth appears on April-May of next year.
The seedlings of first-year are wintering badly in the
open soil; therefore, it is better to keep them in the
basements in sand. When one-year seedlings are
planting next spring we receive the standard seedling
in the autumn this year. Planting material of high
quality of Hibiscus Syrian was grown by means of
inoculation and by the grafting method. It is
recommended to execute an inoculation in the first tenday
period of September. It is possible to execute the
reproduction by means of inoculation in case of deficit
of shoots of high quality plants and for the rapid fixing
of sort. It is preferable to reproduce a Hibiscus Syrian
by wood shoots in the frames or by green shoots in the
unheated greenhouses in an autumn-winter period. The
best results in the carried out research were got at
planting shoots for further growth in the containers at
the greenhouses with creating of shadow in a summer
period. The high speed of shoots growth in the
containers of cv. Duc de Brabant, cv. Woodbrige and
cv. Russian Violet varieties are observed. The
vegetative mass of shoots of cv. Speciosus,
cv.Carneus Plenus and cv. Red Heart varieties
increases more slowly. A conclusion follows, that the
studied crop must take the deserving place in the
assortment of decorative bushes of plant nursery farms
In the article we have proposed the technology of repair works using improved soil mixture sifting the rubble and ash using soil mixture installation and without it. For prevention of occurrence of defects and damages we have offered an antifiltration device
in the form of screen and core from compacted obliquely pulled layers of impermeable soil
The total area of saline soils of rice irrigation systems in the Kuban region reaches almost 80 thousands hectares. Salinization and alkalinization here become a limiting factor for cultivating rice and companion crops. In this regard, the tolerance of plants to soil salinity is a current problem of plant breeding that attracts the attention of many agricultural researchers whereas it is necessary to increase the yield in saline soils. Salt tolerance of crop plants is defined by a combination of properties which are based on the specific adaptation mechanisms. These mechanisms differ in nature and are associated with different levels of structural organization of the plant – from molecular to organismic one. The study of adaptation mechanisms at different levels of structural organization of plants is very important for increasing yield in saline soils. This article is a review giving a detailed analysis of plant salt tolerance research, particularly rice, which addresses the issues of inhibition of plant growth under saline conditions, the mechanisms of salt tolerance, the achievements and development of this branch of scientific research, as well as the application results of work found in the scientific literature
