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 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 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 present article is concerning with the research of
influence of new mineral additive «Koretron» in diets
for young pigs on meat performance. The mineral
additive «Koretron» adsorbs and removes mycotoxins
from the body and is the source of water-soluble
silicon, which is necessary for stable functioning of
intestine and stomach smooth muscles and for
improving of calcium digestibility. It is proved, that
the considered feed additive has positive effect for
animal growth intensity because it has contributed to
increasing of both total and relative weight gain of
young pigs on fattening. It is determined, that the
mineral additive «Koretron» has positive influence on
meat productivity of animals from the test group:
killing-out percent, hot carcass weight, rib-eye area as
well as weight and meat yield, fleshing index have
been increased. The considered mineral additive has
contributed to improving of chemical composition of
meat: the content of dry matter both in the average
meat sample and in the longissimus dorsi, content of
nutrients synthesized in carcass meat, energy value of
carcass meat, biological value of meat have been
increased. The data received during our test give
evidence of high bioavailability of water soluble
silicon in tested additive, which has activated
metabolic processes in the bodies of young pigs on
fattening and, as a consequence, the gain of their live
weight has been increased and morphological structure
of carcasses and meat quality have been improved
