The nutrient structure of fruits of the Mountain ash of
ordinary Sorbus aucuparia L., sloe of Prunus spinosa
and their extracts is investigated. Inside them, the
standard methods in biochemistry have determined the
content of extractive substances, sugars, titrable acids,
vitamins C and P, phenolic and pectinaceous
substances. Results of analyses demonstrate that the
fruits of wild plants ripening in the conditions of
Dagestan – mountain ashes and sloe - can be
effectively used as raw materials for receiving extracts
which are rich in vitamins, carbohydrates and phenolic
connections. The possibility of production of highquality
nutrient-rich extracts from these fruits with
application of various technological modes and ways
of extraction is revealed: duration of insisting of raw
materials; various concentration of ethanol in an
extractant and ratios raw materials/ extractant. Results
of researches demonstrate that at a ratio of raw
materials/extractant 1:3 and the 70% content of ethanol
in the extractant have come the greatest extraction
from vitamin fruits P (routine) and phenols which
made respectively 56,0-65,7% and 51,4-68,3%.
Increase in extraction of titrable acids and vitamin C is
noted at 50% concentration of ethanol in the
extractant. The maximum release of sugars has come
from all fruit substrata at 30% ethanol in the
extractant. Results of biochemical analyses of extracts
have shown that carrying out extraction in the way of
double insisting on condition of selection of optimum:
concentration of ethanol in the extractant, ratios of the
raw materials/ extractant and the best time of insisting, allow to provide on average a 55-60% exit of nutrients
from the studied fruit raw materials
This article notes that agricultural production is not a self-regulating system. The article highlights specific features of agricultural production and forms of ownership of the major productive resource – land, ineffective policies of promoting development and introduction of innovative technologies. It is noted that the system of measures and tools of state regulation of agricultural production have two directions of influence: governmental regulation of the agricultural market mechanism and industrial governmental support for manufacturers. The authors give classification of methods and instruments of state regulation, liberalization of the agricultural sector in the WTO, levels of aggregate support for agriculture; as well as identifies the key growth areas of the governmental support and discusses the basic institutions of governmental regulation: ownership, legal Institute of economic management and the Institute of organization management. It's pointed out that the current dynamics of the development of agricultural production in our country is determined by four major external factors: the Institute of Western sanctions imposed against our country, Russia's integration into the international market by joining the World Trade Organization, the functioning of the Single Economic Space within the Customs Union, and the necessity of solving problems of import substitution and food security of our country. Implementation of these methods requires significant institutional transformation and transition into the new levels of legal, commercial, and economic regulation with observance of equitable international cooperation. In conclusion, the authors discuss an insufficient level of development stimulation in domestic agriculture
The article shows the historically developed situation
and the actual state of the production practice in
chronic mycotoxicosis of a bird. The main feed
problems in poultry farming are shown through the
prism of a review of market proposals for feed
concentrates. An overview of preventive and
compensating agents on the market, as well as a brief
description of feed concentrates based on beta-carotene
for fighting mycotoxicosis. It is shown that the
vitamin-mineral fodder concentrate "Tetra +" is an
alternative to the existing feed concentrates on the
market, the effectiveness of which has been confirmed
in experiments on laboratory animals and in poultry
feeding. Based on the analysis, a conclusion was made
about the relevance of studies to identify the
effectiveness of vitamin-mineral concentrate "Tetra +"
in livestock
Duration of vegetation period is one of the main
adaptive traits for any crop or variety. Reasonability
of cultivation of a variety in a particular soil and
climate zone is determined by the duration of the
vegetative period. One of the aims of breeding is
the creation of the varieties with the main vegetative
phases lasting at more favorable climatic conditions.
The most accurate way to determine maturity
group of a variety is by estimation of starting
of heading phase, which can be defined with the
greatest precision. The article covers the analysis of
the duration of the vegetative period of the lines
and varieties of winter barley of local and foreign
selection in the central zone of Krasnodar region.
All the varieties were divided into three maturity
groups. The vegetative periods of the varieties were
studied during four years. The most favorable and
adverse conditions for yield formation were determined.
The interactions between the productivity of
the varieties depending on maturity group were
identified. The varieties of the early maturity group
which are more productive than the check were
selected, which is most valuable for the breeding of
the crop. The best varieties with the high and stable
yield and the positive traits are regularly involved
in the breeding programs with the porpoise of making
new varieties of the winter barley
For the production of high quality winter wheat grain,
it is necessary to observe the technology of growing
the crop and creating optimal conditions for the growth
and development of plants. An important role in it is
played not only by agrotechnical measures, but also by
effective protection of crops from pests. The
phytosanitary state of winter wheat sowings has
worsened significantly in recent years, however, the
degree of damage to crops and the harmfulness of
fungal diseases can be significantly reduced, and in
some cases completely prevented by treatment of crops
with fungicides. The range of fungicides is improved
annually by incorporating more effective and less
environmentally hazardous preparations. The research is aimed at determining the optimal rates of
consumption, the biological effectiveness of new
fungicides and assessing their effect on the yield of
winter wheat. As a result, it has been established that
treatment with Abucus Ultra with a rate of 1.0 l / ha
has protective properties, but does not treat plants
(72.2%). This further leads to a loss of an average of
about 0.5 tons of grain per hectare. Fungicide Akanto
Plus in the investigated rates of consumption has good
protective and eradicating (healing) properties and
with a decrease in the rate of consumption of less loss
of yield. Thus, the choice of the preparation and its
consumption rate should be based on an understanding
of the phytosanitary situation, taking into account the
condition of crops and the agroclimatic situation
The dependence of the productivity of the Riesling
Rennel vineyards and the quality of table wine from it
under the conditions of the Anapa-Taman Winegrowing
Zone was studied. It is established that the
vineyards of the Riesling Rhine variety are planted
with the highest yield, planted according to the
scheme of 3.5x1 m. In this embodiment, at a density
planting shrubs 2857 pcs. / Ha, the yield of grapes was
the highest - 131.4 c / ha. Maximum accumulation of
sugars in the grapes observed in the variants with a
width of 2.5 m aisle highest extract content from
different wine stocks options with row spacing of 2.5
m where the amount of extractables amounted to 17.1
- 19.2 g / dm3
. The increase in the total concentration
of aromatic compounds of up to 540 mg / dm 3
helps
to improve the quality of white table wine, and further
growth of aromatics to 1090 mg / dm3
- it reduces the
organoleptic evaluation. High tasting marks (7.88-8.29
points) received wine materials from sites having a
spacing of 3.5 m. Thus, considering the quality of the
wine, the cost of planting material, laying and care of
vineyards, it is worth considering the 3.5x1 planting
scheme , 5 m more suitable for the production of
quality table wines in the Black Sea agroecological
zone of viticulture in the south of Russia
Elements of the cultivation technology of winter wheat variety called ‘Antonina’ with the application of different backgrounds of soil fertility, norms of fertilizers, system of plant protection from weeds, pests and diseases were studied. The studies are conducted in a polyfactorial stationary experiment: factor A - soil fertility; factor B - system of fertilizers; factor C - plant protection system; factor D - methods of basic soil cultivation. In the experiment four models of soil fertility levels were studied: А0 - the initial (natural background); А1 - average (200 kg / ha Р2О5 and 200 t / ha of litter manure); А2 - increased (doses are doubled); when А3 - high (tripled). Based on the studies it has been established that to obtain a stable yield of winter wheat, an increased dose of mineral fertilizers should be used, which also ensures high grain quality indicators. The maximum yield increase of 37% was achieved on varieties in comparison with extensive technology. A significant increase of the protein content in the grain from 12.8 to 15.3% and gluten from 22.0 to 27.8% was found in the intensive technology - triple doses of fertilizers (NPK) and the use of integrated protection against diseases, pests and weeds. The introduction of high doses of mineral fertilizers contributes to the accumulation in the soil and grain of nitrogen, and also reduces the content of copper and zinc
In recent years, many pigs of specialized breeds,
characterized by increased meat qualities, have been
brought to Russia from Canada and a number of
European countries. The article presents the results of
the assessment of slaughter and meat qualities of pigs
of different genotypes. Danish pig meat was used as
research objects: purebred landrace (CHL), benthic
hybrid Landrasx yorkshire (LxY), three-breed hybrid
landrace hyorkshire x dyurok (LxXxD), removed from
control fattening, and developed prototypes of delicacy
products. The commission evaluation of meat and
broth showed that the boiled meat from the three breed
animals received the highest score, and the quality of
the broth significantly exceeded the samples of
purebred landrace and two-breed animals. As a result
of the tasting evaluation of the Voronezh ham, it was
established that the samples of meat from threebreeded
pigs, in comparison with the samples from
purebred meat, show the most pronounced flavor,
aroma and soft consistency
Excess body weight is a serious problem, involving a
set of diseases presently. For this reason, taking into
account demands of science there was a development
of production of food with the lowered energy value
for the people having first of all obesity that led to
production of substitutes. Even more often producers
resort to use of nutritional supplements, which
generally receive in synthetic way. In this article, we
analyzed multiple references and summarized the
material regarding beet fibers. As a result of numerous
researches it has been proved that food fibers make
favorable impact both on the separate systems of a
human body, and on all organism. The use of the
minor products of processing of the plant raw material
is also critical; they allow improving the preventive
properties of products and enriching them with dietary
fibers, protein, and mineral elements and also
development of food development of curative and
preventive action. Citri-Fi food fibers which are
received from dried-up orange pulp are well-known,
they can keep a large amount of water throughout
technological process. They exert positive impact on
structure of fat that gives the chance to create a
product with the lowered content of fat
The article presents the results of the study of the
effect of the size of the explant clonal rootstocks for
stone fruit crops of the Krymskaya OSS VIR VSL-1,
VSL-2, LC-52, RVL-1, RVL-7, VVA-1, AP-1 injected
in vitro and concentration vitamins and
phytohormones in a nutrient medium on the efficiency
of introducing in vitro of these rootstocks. The optimal
size of the injected in vitro explant was determined and
nutrient medium in the first stage of micropropagation
was optimized. The optimal size of the dissected
meristem, which provides the maximum percentage of
explant initiation is 0.4 mm. The modified version of
the nutrient medium based on the Murashige and Skug
prescriptions with a reduced content of vitamins B1 0.1
mg / l, B6 0.4 mg / l, PP- 0.4 mg / l, and phytohormone
6-BAP - 0.3 mg / l. at the first stage of cultivation of
explants of clonal rootstocks for stone fruit crops is
optimal. The survival rate of explants in all tested
samples of clonal rootstocks on this modified nutrient
medium was in the range of 92.5-97.5%
