The article presents the data on the formation of the embryonic fruitfulness of central ovaries of wintering buds of the group of technical grape varieties with white berries - White Muscat; Pinot White, Chardonnay, Citron Magaracha, Pervenets Magaracha; Riesling, Viorica, Riton, Crystal in the conditions of Anapa-Taman zone. There were revealed the rates of embryonic fruitfulness of central ovaries of buds of studied cultivars and fruiting indices of vegetative shoots developed from them. In all studied grape varieties there was revealed a high percentage of fruitful buds from 84,1 in the variety of Riton at 97.2 at Viorica; and the percentage of fertile vegetative shoots from 81,8 at the variety Citron Magaracha to 97.2 in the variety White Muscat. At the leveled load of bushes, vegetative shoots and the same scheme of planting of bushes (3 x 2 m), the highest yield in terms per hectare showed the varieties Pervenets Magaracha, Viorica, Riton, Crystal, Riesling and Citron Magarach. When assessing the economic efficiency the highest net income and level of profitability were identified in the varieties of Citron Magaracha, Pervenets Magaracha, Viorica and Riton. In order to determine which buds will give us shoots with large, well-developed (well-differentiated) buds, and which will not give (weakly differentiated), it is necessary "to look inside a bud". But even already formed germs of inflorescences in the bud are able in a few days in spring or dedifferentiate or degrade depending on the influence of external conditions. Scientists have learned to use this ability to increase the maximum possible yield in years of severe damage of grape by frosts. Firstly, in frosty winters the central buds wither out. The replacing buds usually have poor fruiting and bad productivity during years. In such cases, it is more profitable to conduct a small cutting of angle buds arranged in a circle at the base of a shoot. At the beginning of the second vegetation phase, these buds will obtain the great bulk plastic substances, which will cause the dedifferentiation of rudiments of inflorescences in them. Thus, it is possible not only to restore rapidly the normal shape of a bush, but to obtain a good harvest this year
The influence of the predecessor and different doses of mineral fertilizers on the yield and the quality of the winter wheat cultivar ‘Krasnodar 99’ were investigated. Investigations were carried out in the North-Kuban Agricultural Experiment Station in two ten- course crop-rotations: grain plowing and grain - grass plowing (stationary experience). The soil is the black soil, low in humus, powerful, with humus content 3,95-4,00%, depending on the nutrition in the arable soil layer (0-30sm), mineral nitrogen is 5,9-8,3 mg / kg of soil, exchangeable potassium is 330-360 mg / kg of soil. It was found that the maximum value of the winter wheat crop structure elements is noticed in the fertilizer systems with complete mineral fertilizer, and the minimum value - with PK and NK. Winter wheat yield depends on the crop rotation of 8-15%; from its predecessor - 15-18% and 27-31% of the fertilizer. The protein content was mainly determined by the fertilizer dose. Enhanced and high doses of fertilizers contributed to an increase in the protein content to 12%.A strong correlation between protein content, agronomic methods and precipitation was determined
The reaction of winter wheat of Krasnodar
Agricultural Research Institute selection that is
included in the State Register of selection
achievements in the Russian Federation, on the
predecessor, the sowing time and the level of mineral
nutrition in 2008 - 2010 was studied in
"Severokubanskaya agricultural experimental station"
P.P. Lukyanenko Krasnodar Agricultural Research
Institute, located in the northern area of the region.
The objects of research were cultivars ‘Bezostaya 1’,
taken as a standard, ‘Tanya’, ‘Grom’, ‘Sila’, ‘Ligue 1’,
‘Irishka’ and ‘Yumpa’, with a specific weight of
strong wheat (excluding the cultivar ‘Bezostaya 1’) -
57.1%, essential - 28.6%, weak - 14 3%. The
predecessors are winter wheat, sunflower, white
mustard. Seed dates: the 20th of September (optimal
for determining the originator of the cultivar) the 1st
and 10th of October. The background of mineral
nutrition is N0P0K0, N60P30K30 and N120-160P90K60. The
soil is an ordinary powerful heavy-loam chernozem
with humus content in the soil layer 0 - 30 cm 3.95 -
4.00%, of mineral nitrogen - 8.3 - 10.7 mg / kg of soil,
of mobile phosphates - 22.4 - 26 6 mg / kg of soil, of
exchangeable potassium - 330 - 360 mg / kg of soil.
Weather conditions during the research were
extremely contrasting, both by the precipitation and by
the temperature conditions. Based on these studies, it
was found that five or six cultivars of this crop that
differ in biological and economic features, the reaction
on the predecessor, soil fertility and sowing terms as
well as adapted to the specific soil and climatic
conditions should be used to obtain consistently high
yields of winter wheat. Well-chosen cultivars, predecessors and sowing terms predecessors allow
without additional cost on the unfertilized background
to increase the yield on 0.20 - 0.79 t / ha. Together
with the growth of yield, the technological quality of
grain is improved: protein content by 0.5 - 2.4%, fibrin
content - 1.7 - 7.6%. The principle of mosaic use of
cultivars with specific predominance of strong wheat
is 57.1%, essential - 28.6%, weak - 14.3%, it allows to
produce the grain when you apply the minimum dose
of 12.5% protein content, 20.9% of fibrin content.
When using N90P60K60 respectively 13.3 and 23.6% at
a dose N120-150P90K60 - 14.4 and 26.8% with an average
of 13.5 - 24.0%

The article presents results of the study of yield, mechanical composition and quality of bunches of newest white grapevine varieties called Artemis, Sauvignon tamanskii and Inkroche tamanskii, in the conditions of Taman in the Krasnodar region. The yield of the studied genotypes ranged from 10.4 to 13.3 t / ha: the highest yield was in Artemis, and the lowest – in Sauvignon tamanskii. The average weight of the bunch was in Sauvignon tamanskii (152 g), the variety Artemis had 143 g and Inkroche tamanskii had 130 g of bunch weight. The percentage of berries in clusters ranged from 95.3 in Artemis to 95.9 in Inkroche tamanskii and Sauvignon tamanskii. The ratio of fruit mass to the mass of crests was 20.3 in the varieties of Artemis and 23.5 in Inkroche tamanskii and Sauvignon tamanskii. In genotypes of Artemis, Sauvignon and Inkroche Taman Taman the weight of 100 berries was 200, 160 and 130 g, respectively, the mass of 100 seeds - 4.6; 3.1 and 2.9 g, the average weight of the pulp from the juice to the weight of the skin - 24.3; 19.5; 15.9. The percentage of pulp and juice in clusters of the studied varieties was 85,9-89,1%, and the ratio of pulp to juice to the solid residue 6,1-8,2. Yield of musts from the studied sample was 74,5-75,4%. The content of sugars in the berries (17,5-19,6 g / 100 cm3) was dependent on the yield, the characteristics of varieties and timing of the harvest, but the harvest was favorable for the production of beverages and wine materials
The article deals with the issue of improving the
profitability of sheep breeding by using improved
mutant genotypes in the breeding system. The results
of studies of the main indicators of economic-useful
traits are given, the dynamics of growth, level and
quality of wool productivity of sheep of improved
genotypes obtained on the basis of such breeds as
Soviet merino and Stavropolskaya, as well as firstgeneration
daughters cultivated in themselves are
estimated. It was found that at birth, the live weight in
the groups of the 3 group (the breeding of half-blooded
hybrids "in oneself") was higher than that of the
females from the 1 and 2 groups, respectively, by 0.50
kg, or 13.1%, and by 0.20 kg or 5.2% (P> 0.95). At a
more senior age, the young, having a large live mass at
birth, retained its rank position. The highest indicator
of the cutting of physical wool was observed in animals
of the 2 group, obtained as a result of the use of sheepproducers
of Stavropolskaya breed on sheep of the
Soviet merino. The parameters of the 1 and 3 group
were lower by 0.6 kg - 12.3% and 0.17 kg - 3.5% (P>
0.95), respectively. The conclusion is made that the use
of sheep-producers of the Stavropolskaya breed on the
uterus of the Soviet merinos breed had a positive effect
on the wool productivity and the live weight of the
hybrid offspring. Further breeding of half-blooded
hybrids “in oneself” showed the possibility of
reproducing improved genotypes without losing the
acquired qualities
The reaction of winter wheat cultivar ‘Antonina’ on the level of fertility and doses of fertilizers on crop productivity was studied. Investigations are carried out in multivariate 11 –course crop and grain-grass rotation stationary: factor ‘A’- the fertility of the soil; factor ‘B’ - fertilizer system; factor ‘C’ - the system of plants protection; factor ‘D’ - the main methods of soil tillage. Four models of soil fertility levels were studied in the experiment: А0 - initial (natural background); А1 - average (200 kg / ha Р2О5 and 200 t / ha of solid manure); А2 - high (double dose); at А3 - high (tripled) on three backgrounds of basic soil cultivation: nonmoldboard, recommended, moldboard with deep bursting and without the application of tillage (direct seeding and the natural rate of soil fertility). The soil is heavy leached black humus with humus content in the arable layer of 2.5% - 2.9%. On the basis of proven researches it was found that for the sustainable yield of winter wheat the dose of mineral fertilizers should be increased and nitrogen - up to 140 kg per hectare. The increase in yield is due the rise of the quantity of grains per ear and weight of grain per ear
