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
Productivity of seeds of cereal crops essentially
depends on the quality of the seed grain, which is
being defined both by biological condition of seeds
and technologies and technical resources, which are
being used in, machine processing of seed heap. In this
connection, different injuries of weevils which are
occurred while mechanical and thermomechanical
influences from tools of machines and aggregates have
got vital importance. Apart from the breaches of
integrity of the weevil’s cover there are also exist
traumatizing changes of its inside structures which are
frequently covered with casings and do not being
viewed with visual inspection. Conditions of inside
structures of weevils were researched with
radiographic method and also were defined possible
types of traumatizing changes which depend on
mechanical and thermomechanical influences, which
were eliminated in universal classification of injures
among the inside structures of seeds of agricultural
cultures. Also, wу have analyzed the influence of
chosen types of injuries on seeds’ sowing qualities and
found that all injures of weevils essentially and
differentially influenced the sowing and fruitful
qualities and should be considered while choosing the
technological schemes of preparation, working tools
and while tuning the aggregates’ regime of work
attached to the machine processing of grain and seed
heap
This article presents results of trials of feed additives
called "Yoddar-Zn" and "Glimalask-Vet" to improve
quality characteristic of meat of beef cattle. It was
established that the most efficiency of these additives
was achieved when used in complex. The carcasses of
calves, which were consuming a complex of additives
"Yoddar-Zn” and “Glimalask-Vet” (I c.), contained
meat of the highest sort more than control by 6.48 kg,
the animals which consumed only "Yoddar-Zn” (II c.)
- 3.50 kg, the first-sort - at 15.19 and 7.86 kg. In
experimental groups of calves there were observed
more intense integral characteristics of meat color. The
flesh of carcasses from the calves of experimental
groups, the fat was higher than control, 0.13 and
0.07%, protein - by 1.79 and 0.97%. Animals
experimental groups synthesized more protein at 5.45
kg, or 13.70%, and 2.62 kg, or 6.59%, energy - to
304.3 MJ, or 18.17%, and 146.8 MJ, or 8.77%. Meat
of experimental animals, contained more essential
amino acids. Protein meat quality indicator was higher
than control, 0.73 and 0.28, amino acid index - by 0.17
and 0.04. The meat from calves of experimental group
had a higher culinary and technological parameters,
optimal fractional composition of muscle protein and
lipid composition of adipose tissue, better digestibility
The article contains complex research results dedicated
of reproduction the cattle of the animal breeding
industry in the agricultural holding called “Kuban”.
Key indicators characterizing reproductive function at
cows were set; they were estimated in terms of the
plans of the economy in the milk cattle breeding
industry. The reduced values of the birth-rate of calves
were revealed on 100 cows and in the term of the
production use of cows, their main reasons were set.
The performed calculations prove the possibility of
increasing the profitability of milk production
This article presents the results of the impact of
"Gorlinka" mustard protein-containing feed
concentrate in the feeding of broiler chicken of the
cross of "Cobb-500" on their performance and
nutrient digestibility of the feed. The studies were
conducted in the conditions of Krasnodonskaya
Poultry farm in the Ilovlinskiy district of the
Volgograd region. Full or partial replacement of
sunflower meal with "Gorlinka" mustard proteincontaining
feed concentrate in the feed mixture for
the experimental broiler chickens contributes to the
increase of the coefficients of digestibility of nutrients
compared to the birds in the control group. The use of "Gorlinka" mustard protein-containing feed
concentrate in the composition of feed for broiler
chickens has contributed to higher coefficients of
digestibility of nutrients: dry matter – 0.51-1,37%,
organic matter – 0.6-1,99 %, crude protein by 0.8-
2,24 %, crude fiber – 0,34-1,65 %; crude fat – 0.94-
2,29%, compared to the birds in the control group.
Nitrogen balance was positive in all groups; the use of
nitrogen from the accepted experimental broiler
chickens was higher in the experimental groups than
in the control by 2.89-of 7.93 %. The use of nitrogen
from digested nitrogen was higher in the experimental
groups in comparison with the analogues from the
control group by 2.65-of 7.97 %. The use of calcium
and phosphorus by poultry was also higher in the
experimental groups
The fattening of Holstein cattle for more than 90 % provides the beef cattle division of the firm «Agrocomplex» based in the village of Vyselki, the Krasnodar region. The share of the Aberdeen Angus breed is 6.3 % and Charolais at 0.6 %. The reason for insufficient supply with fattening complex of Charolais cattle is a high indicator of severe parturition, postpartum complications, and reduced productive longevity of cows of breeding herds of these breeds. In a "Livestock complex" bulls of breeds of Holstein, Charolais and Aberdeen Angus reach the required values of live weight for the established standards of the breeding time. Charolais have the best indicators of absolute and relative weight gain and the shortest feeding season. The profitability of cattle fattening in CJSC company "Agrocomplex" is low, but the efficiency of the industry is ensured by the presence of its own processing plants. To improve the profitability of beef production it is required to increase the proportion of specialized breeds for meat productivity; to generate the most uniform by age and live weight of the group; identify the cause of the high rate of culling of Charolais cows for postpartum complications and take action to address them
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%
27 introduced variety samples of rice from 8 countries
were studied by the complex of biological,
morphological, agronomic traits to select the most
valuable genotypes for including them into breeding
programs on development of cold tolerant rice
varieties. It was found that the studied introduced
varietal samples were characterized by variation in
duration which varied from 120 to 182 days. Variety
samples from Bhutan ATTEY, PARO DUMBJA
(White) had shown response to photoperiod and the
panicles didn’t appear in conditions of Krasnodar
region. During the study there were selected high
productive forms Obongbueo and Tinbubueo from S.
Korea with grain weight 81.67 g / vessel and 74.43 g /
vessel, respectively. According to results of research
there were selected five cold tolerant samples Tong
Jing 29 (China), Giza 178 (Egypt), Istigbol and
Mustagillik (Uzbekistan), ZAKHA (Bhutan),
evaluation result of which were on the same level with
those of standard check variety Kuban 3, as well as
those of samples with increased resistance IR83222-
F8-14 and IR83222-F8-156 (Philippines), PARO
DUMBJA (White) and THIMPHU DUMBJA
(Bhutan). As a result of research there were selected
three introduced rice variety samples Tong Jing 29
(China), Tinbubueo (S. Korea) and SR 30084-F8-156
(Philippines) which by duration, morphotype and
agronomic traits are considered as candidates for
further hybridization and breeding as sources of useful
traits and properties
The researches were carried out with the support of the Federal state budget establishment "The development assistance fund of small forms enterprises in scientific-technical sphere" (Fund for the innovation promotion), contract number 0019671. The fodder additive «Nutovit» in growing chickens feeding application enriched mixed fodder for farm poultry with protein and especially with the amino acid such as lysine. Scientific-economic experiment was carried out at the poultry-farm enterprise of the Volgograd region in 2015-2016. 4 growing chicken groups with 54 heads in each group were selected for the experiment. The growing chickens were selected according to the cross, age, living body weight, health status. The difference in experimental poultries feeding was that in the experimental groups the sunflower oil cake in the feed mixture was replaced by fodder additive "Nutovit". It was established, that the essential amino acids availability and the saturation of fodder additives with vitamins influence positively on: young chickens live weight and average daily growth, the live weight to 120-days age in the second experimental group amounted to 1657 g, and average daily growth was to 12.46 g, which is higher compared to the control group by 4.48 % at 100% poultry livability; blood morphological and biochemical composition: formed elements of blood, namely erythrocytes, in the experimental groups young chickens blood were more in 0.02 to 0.05×1012/l compared with the control one. The researches established that blood leukocytes reduction in growing chickens of the experimental group was little, in 0.04, 0.09, 0.08 ×109 l. Calcium content in growing chickens blood in the control group was 2.6 mmol/L. The experimental group surpassed the control on 0.14-0.21 mmol/L. The phosphorus content in chickens blood in the experimental groups exceeded the control one by 0.08-0.24 mmol/l. In addition, the feeding cost reduction was established due to the fodder additive "Nutovit" use
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
