The article considers the crop rotation with different saturation of rice and measures of struggle against the cereal and wetland weed
Intensification of agriculture during the twentieth
century was accompanied by an increase in
international trade, resulting in the resettlement of
many species across continents. As a result of these
processes, many adventives species have become
economically significant and dangerous plants in agro
and urban biosensors. One such plant is Ambrosia
artemisiifolia L., imported from North America to
Russia. The use of chemical means of suppression of
A. artemisiifolia L. often does not give positive results
in agrocenoses, because of its biomorphological
features. In urban areas, within the boundaries of
sanitary zones, the use of chemicals is prohibited.
Therefore, the most promising direction in the
suppression of ragweed ambrosia is the ecologies
method. The article discusses the possibility of using
an ambrosia leaf beetle in the feeding of ragweed in
the territory of Russia
The article reflects suggestions about creation of legislative base for rabbit-breeding development at region level. It proposes concrete actions that can promote development of rabbit-breeding production and need a state support. The author gives description of phased strategy of the rabbit-breeding business development in Krasnodar region
The essential new approach to soil processing taking into account its origin as a geologically disperse body is offered. The soil should be processed not only using its natural dispersion, but also optimizing this geological deposit taking into account decrease in its dispersion in process of a geological and biological sedimentation in the field of weight of Earth. The new technical solution is proposed for rotational intra soil cultivation. The problem is solved to transfer a torque to the tool being inside the processed geological body
In order to find compounds that increase sugar beet
resistance to the adverse effects of herbicides, a
series of pyridylhydrazone derivatives have been
synthesized. The protective effect of new
compounds for the herbicide mixture Betanal,
Lontrel and Super Zeleke was studied in field
conditions. The effect of pyridylhydrazones on the
synthesis of photosynthetic pigments in leaves was
investigated. Substances with a high protective
effect were found
The article studies the influence of the interaction of two technologies of plant protection: breeding- immunological and chemical. The studies were conducted on the varieties and lines of soft winter, durum wheat and triticale, established in Krasnodar research institute named after P. P. Lukyanenko, and also, on varieties of an alien and foreign selection. When considering the correlations in the group of genotypes, forming a necrotic type of reaction to the introduction of the pathogen (the first group of varieties), the significant negative correlation (r - 0,76) between the change in the mass of 1000 grains and the number of unproductive stems formed by one plan was established. The model of the severity of brown rust pathogen in sparse crops of wheat has been collaborated. According to the model, the development of the pathogen in the tissues of the leaves of the host plant leads initially to a change in the relations of the productive and unproductive stems. The change of these parameters significantly affects on the variability of indicators such as the mass of grains from one ear, number of grains per ear and 1000 grain weight. Negligible volatility of weight for 1000 grains suggests that the major losses of productivity in the flowering stage are due to abortive flowers. This model can explain the increase in the mass of 1000 grains in some varieties for tolerance change experiments with the defeat of plants of P. Triticina on micro-plots
The article presents: the stabilization system of soil acidity, which allows subsoil irrigation tomato plants catholyte to compensate the negative effects of acidic fertilizer, and additionally to prevent plant diseases anolyte solution; transfer function of the stabilization system of soil acidity and the results of its tests
The article presents the results of studies of 92
indigenous varieties and 15 wild genotypes by 24
microsatellite markers. As a result a locus database about
germplasm in the collection stored at the Russian
ampelographical collection AZOSViV (Anapa Zone
Experimental Station of Viticulture and winemaking)
was created. During the research of varietal breeding
populations confirmed the validity in the production of
the cultivar of Krasnostop anapsky with obvious changes
in microsatellite sequences as a clone of famous indigenous
Don cultivar Krasnostop Zolotovskii. This clone
was selected in 1953 by prominent agrotechnologist
Zotkin Ivan Ivanovich which is propagated by the
author and his followers, and after a formal registration
submitted to state testing in 2007 in GSK RF, zoned in
the North Caucasus region (number 6) in 2014 year. Sort
-clone Krasnostop anapsky only in the Kuban today
cultivating in 35 hectares. By using molecular genetic
techniques, now clonal selection of vine grapes is reasonably
improving. Recent data collected by us in the
work process, were analyzed a comprehensive manner,
making it possible to draw conclusions about distinctness
of grape varieties. Some clones were studied by DNA
primers, based on retrotransposon sequences
The peculiarities of development of “phragmites australis” are analyzed at this article. The reed effect on the covering materials is investigated. The laboratory experiments are executed. The sizes of pressure, with characteristic of the generation period, are determined
The process of the presowing seed treatment with alternating electromagnet field of the commercial frequency (EMF CF) 50 Hz is economically efficient. The use of the EMF CF 50 Hz in the unit with ring pole pieces allows increasing the germinating energy and power. The electromagnet seed treatment in the units with ring pole pieces is the perspective process of the presowing treatment which does not make unhealthy influence on the operating personnel. At the presowing treatment we have to take into account three factors, they are the arrangement of seeds in the working chamber, the time of treatment and the seed humidity. In this article the authors recommend to promote the unit consisting of a magnetic circuit with ring pole pieces of the rectangular cross-section, a magnetizing coil and an embedding of the non-magnetic material in the working chamber which allows increasing the germinating energy of spring barley by 10% and the germination by 7%. As field experiences have shown the highest seed germination and good crop capacity take place in the work chamber zone with boundaries R1=0,012 m and R2=0,035 m at seed humidity from 12% till 18% and the time of seed treatment is 0,9-2,75 s. The addition to crop capacity has run to 7% as a result of the spring barley treatment
