In January 2015, at the Vineyard and ZAO "Pobeda" in Temryuk District of the Krasnodar region, the thermometer dropped to minus 21,6 C, which resulted in significant damage to the central wintering buds. The article presents a method of determining the degree of damage of wintering buds. Based on the results of inspection of variety by sections divided into 3 groups.
Group 1: saved between 40 and 72% central. This group includes the following 7 varieties : Pervenets Magaracha (uch. 64) Gibernal (uch. 74/3), Viorica (uch. 77), Riton (uch. 66), Riesling (uch. 82), Traminer (uch. 73/2), Chardonnay (uch. 73/3). Cutting of bushes should be carried out by the usual way. The task of cutting - compensate the loss of crops due to leaving the greater load. Group 2: Central buds was damaged nearly 70-85%, saved from 20 to 35% of replacement buds. This group includes Merlot (uch. 83), Tsitronyy Magaracha (uch. 69), Augustine (uch. 66), Saperavi (uch. 79), Chardonnay (uch. 74/1), Muscat white (uch. 73) Cabernet Sauvignon (uch. 80). During cutting should be left as much as possible of annual shoots and well-developed secondary shoots. Group 3: damaged more than 85% of central buds, replacement buds significantly damaged . To this group assigned Saperavi (uch. 80), Pinot blanc (uch. 74), Merlot (uch. 80/2), Moldova (uch. 70), Chardonnay (uch. 68), Moldova (uch. 22) Kaberne- Sauvignon (uch. 68), Moldova (uch. 38), Arkadia (uch. 78), Tsimlyansky black (uch. 68). Pre-cutting consists in removing all clearly dead and unusable parts of the bush (dried vines, stumps, annual shoots) that will accelerate the development of shoots from the angular buds and resting buds. Considering the high plasticity of grape plants, can not only in accelerated way to restore the crown of bushes damaged by frost, but also get a crop in the current year, using special methods of agricultural technology
The purpose of the researches was the necessity of
deep study of hydraulic dimensionless expense
descriptions of regulative organ of model standard of
band regulator of water, for rice checks. Rice is one
of the most moisture-loving agricultural cultures. Its
productivity straightly depends on adjusting of water
level in rice cotter pins on the different periods of
development of this culture: period of primary
submergence of check, fight against weeds, primary
vegetation, phases of bushing out, vegetations of
suckling and cereous ripeness. On each of the
considered periods of development of plant the
guided water level is needed, that high-quality can be
realized only at application of the systems of
automatic control. In rice irrigation systems there is
plenty enough of losses of water due to not managed
leakage in regulator flow and water level in the
closed position. An actual and meaningful task is
development, research and introduction in practice of
reliable and high-efficiency regulators expense and
water level for rice checks. The article presents
results of research of hydraulic dimensionless
expense descriptions of regulative organ of model
standard, developed by us. Intercommunication of
degree of influence is investigational, on the basis of
application of methods of planning of experiment, on
the function of response, which dimensionless
expense description of regulative organ of model
standard of band regulator of water, relations of
diameters of the downlow openings, is taken for, at
the different relation of workers pressures. From
appraised experimental data approximation
dependences, which were in same queue analysed for
the purpose cross-correlation connection,
determination, elasticity, are built. Also, in the article
there is an estimation of statistical meaningfulness of
the built model of regression given with the use of
criterion of F - Fishera and parameters of
equalization of regression with the use of criterion of
t - St'yudenta, at the set level of meaningfulness α. At
the permanent relations of workers pressures the
analysis of sections of surface of response H/Нmax
0,6; 0,8; 1,0 shows that functions have extremums on a maximum. At minimum relations of workers
pressures H/Нmax equal 0,6 the maximal value of
function of response is equal 81% it will be at the
relation of diameters of the downlow openings of
d/dmax equal 0,9. With the increase of relation of
workers pressures H/Нmax to 0,8 have a trend of
maximum toward an increase and here he comes at
the value of function of response equal 94% and
relation of diameters of the downlow openings of
d/dmax equal 0,92. Further increase of relation of
workers pressures of H/Нmax to 1,0 also results in
the trend of a maximum of function of response
which arrives at a value 118%, here the relation of
diameters of the downlow openings of d/dmax is
equal to 0,94. The combined analysis of curves
shows that at any relation of workers pressures, the
degree of influence on the function of response
increases due to more relation of diameters of the
downlow openings

The article substantiates a necessity to apply the
method of interspecific hybridization in durum
winter wheat breeding, using the present soft winter
varieties for improvement of frost and drought
tolerance at the beginning of germination; resistance
to snow mold, fusariosis and bacteriosis of
ears and grain. The article presents the results of a
comparative study of different types of crossbreeding
at interspecific and intraspecific hybridization
due to germination, emergence, productivity. It has
been shown that intraspecific hybrids ‘T. durum
оз. х T. durum оз.’, interspecific hybrids ‘T. durum
оз. х Т. аestivum оз’ and ‘Т. аestivum оз. х
T. durum оз.’ possessed the highest germination
and emergence with 71,8/75,3% for direct and
60,4/82,5% for backward, 42,8 and 35,5% and
55,4 and 64,1% respectively. In backward (triplecross)
cross-breeding of F1 interspecific hybrids
with durum winter wheat the grain germination
was down to 37,4 and 36,6%, but the emergence
was up to 64,1 and 69,7% and reached the level of
intraspecific hybrids. According to the elements of
ear (head) productivity (grain mass per head, number
of seeds per head), interspecific double-cross
hybrids of the first and the second generation significantly
conceded to intraspecific hybrids, but
they matched them in a number of spikelets and
grain size. The triple-cross hybrids exceed the
double interspecific hybrids in this respect, but
they concede to double-cross and triple-cross intraspecific
hybrids. We studied the principle of splitting of interspecific hybrids of the second
generation ‘T. durum оз. х Т. аestivum оз.’ and
‘T. durum оз. х T. durum оз.’ (direct and backward)
and the triple-cross hybrids obtained from
cross-breeding of interspecific and intraspecific
double-cross hybrids F1 with durum winter wheat
The article presents the characteristics of the mechanical composition of clusters, the chemical composition of grape juice and fresh grapes and wine tasting evaluation of three varieties of table. We have identified the following uvologic indicators of clusters of cultivars Flora, Nisina and Anyuta: structure - 90.0; 91.5; 87.3; addition - 8.0; 6.6; 10.8; structural - 6.4; 5.4; 8.1; berries - 17.6; 15.0; 10.4. In the studied berries of grape varieties the mass concentrations of sugars and titratable acids were in the range 18,1-23,5 and 0,73-0,78 g/100 cm3 respectively. The combination of sweetness and acidity causes high taste properties of grapes. In grape berries of Flora and Nizina the concentration of fructose was two times more than glucose. Differences in the content wine, malic, lemon and succinic acids in berries varieties of Flora and Nizina were insignificant. In the berries of Anyuta variety, the concentration of lemon and succinic acids was more, malic was less than other varieties. Most of the studied varieties of berries contain malic and wine acids. More of cations of potassium, sodium, calcium and magnesium then in other varieties and it contain less than Anyuta berries. The difference in the content of various cations in the berries of varieties of Flora and Nizina is negligible. Tasting score of fresh grape of Flora variety was 7.0, Nisina - 7.8 and Aniyta - 7.6 points
This article is a review work where the role of microelements in life of plants is observed and theoretical and practical issues concerning application of complex microfertilizers enhancing productivity, quality of seeds and grain on rice crops are highlighted. The complexions of the metals used as micronutrients, are an effective form of trace elements and means of regulation of the production process of agricultural crops as seed treatment before sowing, and when conducting foliar vegetating plants. Their inclusion in the system of fertilizer rice to balance mineral nutrients necessary for plant life, providing increased productivity, quality seeds and grains
Among fungus diseases of rice, blast is the most harm-ful. The disease is caused by Pyricularia oryzae Cav. Rice is sensitive to blast at all fazes of vegetation. In Russia, the purposeful breeding of rice varieties re-sistant to this disease began in 1982. Over the past period, the rice varieties which are genetically protect-ed from blast and not requiring crop protection have been created
In the conditions of foothill soil-climatic zones of the Republic of Dagestan we have explored the creation of low-cost intensive apple orchards. This work was initiated by the authors in 2011 due to the Republic "Horticulture Development Program for 2011-2016", according to which, it was planned to plant 6,200 hectares of new gardens. However, the experience of gardening in the Republic, taking into account recently prevailing socio-economic relations, subsidized nature of the economic and a chronic lack of funds, shows the riskiness of the creation of high-tech pillar-dwarf plants with the cost of 1-1,5 million rubles per hectare. Inability to overcome quickly the existing problems in the development of the industry sharp gardening at this stage, forced us to seek a way in a single direction - reducing the cost of the creation of apple orchards, while maintaining their high economic efficiency. Theoretical studies were realized as a planting of the apple garden in the district of Karabudakhkent of Dagestan of four perspective late-ripening varieties on the medium growing rootstock in the spring of 2013. The results of the three years of scientific research were embodied in the creation of intensive apple garden on the medium growing rootstock which allow now to make the following preliminary conclusions: 1.It is possible here in Dagestan to create intensive apple orchards, with an estimated yield of 30-40 tons per hectare, on the medium growing rootstock already at a density of 666 trees per hectare. 2. Cost of such a garden, without compromising quality indicators, can be reduced in the current market price of labor and the necessary materials, up to 214 thousand rubles per hectare, with access to the full return of all costs in the seventh year of operation. Such intensive garden, according to common practice, during the period of operation is able to give at least 22 full-weighty harvests and provide a net profit about 6.6 million rubles per hectare, or 236,000 rubles per hectare per year for the entire period of alienation of the land for a garden
In the Krasnodar region there is a unique gene pool of animals both for dairy and meat. To assess the heifers the authors formed five experimental groups of animals, the most common species in the region. The authors studied the main economic, biological and exterior features: live weight, measurements, assessment of the exterior. The studies found that among intensive species with the largest body weight throughout the growing period, in 8-month old Charolais heifers superior Simmental ones at 17.4 kg. In one year old Simmental heifers were 9.2 kg (R˂0,05) ahead of Charolais and in 15 months – 10 kg (R˂0,05). Over the entire period of growth the highest rates of relative growth rates of heifers were obtained by red steppe breed type named Kuban, which had an advantage over the Aberdeen-Angus – 19.1%, Charolais – 5.6%, Hereford – 6.2%, and the difference between them and Simmental weren’t fixed. When growing, the animals become less tall, more stretched, wide and massive. We have noted that during the period of cultivation we had increased indices: stretch (9% – Red Steppe, 13.8% – Charolais, 16.1% – Hereford); chest (5.4% Aberdeen Angus). This reduces the index of long legs of red steppe – 5.6%, 10.9% for Charolais. The study of linear growth of animals confirms that the animal meat breeds of live weight increase was due to the extension of the body and increase the width of the pelvis and chest. Some different facts were observed in heifers of Red Steppe breed. For them, the most characteristic increase in the width of the chest was 1.44 times, as well as increasing the depth of the chest and chest girth behind the shoulders
