We have studied the effect of presowing enrichment
with copper on the seed yield of rice. We have found
optimum concentration of water solution of copper,
which provides higher yields of seeds and evaluated
the impact of the enrichment with copper on the
growth processes in the plants of rice. The studies
were conducted in elite seed-growing enterprise
"Krasnoe" of All-Russian Research Institute of rice.
It was found that for rice-growing farms of the
Kuban region with the aim of increasing the quantity
and quality of grain yield it is necessary to make
sowing of rice seeds enriched with copper. This
application should be carried out by wetting the rice
seeds with 0,5 % water solution of the microelement
with a semi-dry method, i.e. the rate of 10 liter
working solution of copper in 1 ton of seed. The
article proves the economic feasibility of enrichment
of rice seeds with copper
To develop the novel herbicide antidotes for the
sunflower vegetative plants, the group of chemical
compounds, belonging to the derivatives of 2-
alkylthionicotinonitrile was synthesized and their
antidote activity both in the laboratory and field
experiments was studied. The compounds with a high
antidote effect were found
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
The article considers the current state of production
of grain crops in the Republic of Sakha (Yakutia).
The analysis of gross collection, structural shifts,
sowing area and yield of grain crops over the past
five years is being carried out. Also, the application
of mineral and organic fertilizers to crops of cereals
is being investigated, since their application is of
great importance for obtaining high and stable
harvests of grain crops. Based on the results of the
analysis, conclusions were drawn and ways of
development of grain production in the republic were
outlined
