AUTOMATED SYSTEM-COGNITIVE ANALYSIS OF ANTIBIOTICS IN VETERINARY MEDICINE
06.02.00 Veterinary and Husbandry
Description
Antibacterial chemotherapeutic drugs, which include antibiotics and synthetic antimicrobial agents, are widely used in veterinary medicine for the prevention and treatment of diseases caused by microorganisms. Antibacterial agents can be classified by type of action and chemical structure. It is also known that when several drugs are used in combination with each other, they interact within the body with each other, which can lead to strengthening or weakening of their action. For these reasons, it is of scientific and practical interest to develop a classification of antibiotics by their characteristics and principle of action (task 1), as well as by mutual compatibility (task 2). The article solves these problems using a new method of agglomerative cognitive clustering, implemented in automated system-cognitive analysis (ASK-analysis). This method of clustering has a number of advantages over the known traditional methods of clustering. These advantages allow us to obtain clustering results that are understandable to specialists and amenable to meaningful interpretation, which are well consistent with the experts ' assessments, their experience and intuitive expectations, which is often a problem for classical clustering methods. The article provides detailed numerical examples of solving two problems. The universal automated system called "Eidos", which is a tool of ASK-analysis, is in full open access on the author's website: http://lc.kubagro.ru/aidos/_Aidos-X.htm. Numerical examples of solving veterinary problems with the use of artificial intelligence technologies are placed as cloud Eidos-applications and are available to everyone

ANATOMICAL AND MORPHOLOGICAL COMPARISON OF PEPPERMINT (MENTHA PIPERITA)
Description
The article presents experimental data of comparing anatomical and morphological features and properties of two peppermint varieties in the Hyaginsky district of the Adygea Republic. The economic importance of peppermint is very high. The essential oil rich in menthol, obtained from the leaves and mint colors, is widely used in the medical, perfumery, cosmetic and food industries. In this regard, of great value are varieties of a complex purpose - with high leaf productivity and high % essential oil and menthol. Comparative analysis of morphological and anatomical features of peppermint raw material of peppery two varieties harvested in the territory of the Farm Sazonenko NV of Giaginsky district of the Adygea Republic, showed that the external features of plants differ from each other. The Kubanskaya 6 variety leaves have a larger size, with a higher content of essential oils, incl. menthol. In this regard, the yield of this variety was higher than that of Prilukskaya 6, and therefore the economic indicators of cultivation of the Kubanskaya 6 variety were the best

Description
In the conditions of the Northern and Southern foothill zones of the Krasnodar Territory, the soil preparation Reasil® Soil conditioner was tested to study its effect on the water – physical properties and structural state of the chernozem of ordinary and alluvial meadow soils. Field and field experiments were conducted in the Northern Zone when maize was cultivated in irrigation. The preparation was applied before sowing by the spreader "Amazone" under pre-sowing cultivation (to a depth of 12 cm) at a dose of 400 kg / ha. In the South foothill zone, the experiment was conducted on a crop – a seedling tomato. The preparation was applied before planting seedlings in a dose of 200 kg / ha. It was established that the application of meliorant did not significantly change the density and total porosity in the arable and subsoil layers of alluvial meadow soil, which was 1,46–1,47 g / cm3 and 44,3–44,5 %, respectively, with practically no pores occupied air (porosity of aeration). However, the use of ameliorant on this soil contributed to an increase in the content of agronomically valuable aggregates in the arable and subsoil horizons, respectively, by 15,9 and 22 %, and the sum of waterproof aggregates by 8,4 and 1,5 %. In the northern zone, when maize was grown, it was established that the application of meliorant did not significantly change the soil density and total porosity in the arable and subsoil layers of the chernozem plain, where it amounted to 1,29–1,32 g/cm3 and 51,6–51,5 % at rather high aeration porosity. The meliorative method reduced the content of agronomically valuable aggregates in the arable layer of chernozem by 15,4 % and increased their quantity in the subsoil horizon (1,4 %). The number of waterproof aggregates increased on the variant with the use of ameliorant, respectively, by 19,9 and 2,8 %

Description
This article discusses the results of research on the effect of soil treatment on agro-physical performance and productivity of major field crops. The task of the research was to determine the impact of primary tillage (moldboard plowing), surface treatment (minimum) and zero (direct seeding) is factor A, fertilizers – B, and herbicides as factor C for agro-physical properties of soil. We have found that high density led to a significant increase in the proportion of the stone faction in the structural composition of the soil. Deterioration of the agro-physical properties while minimizing soil tillage has negatively affected water, air and food regimes under crops rotation. When all methods of soil tillage are applied, the moisture reserves in the 0-200 cm layer in early spring had the lowest values of moisture-holding capacity (230-272 mm) and were defined by the features of weather conditions and past cultures. At the time of sowing, their number decreased by 12% (203-241 mm). The most economical way of spending moisture was shown by plants on the moldboard tillage. In autumn, fewer weeds (7-11 PCs/m2) there were in the options for ploughing. When the surface and zero ways of soil treatments were applied, their number for 1 m2 was 1.2-1.9 times bigger. We effectively eliminated weeds only when applying herbicides. Different crop cultures reacted differently to minimizing the tillage. The greatest reduction in yield was observed when applied surface and zero tillage in cultivated crops. Thus, studies have shown that in order to obtain maximum yields of field crops of crop rotation, reducing production costs, there must be a rational combination of deep or conventional plough tillage for surface or zero tilled for grain crops

Description
The article deals with the realization of the re-productive potential of wheat with the use of multi-flower formation as a model object of winter soft wheat plants. The essence of the concept of "reproductive potential" is disclosed, as well as the significance of this concept for research aimed at increasing the productivity of wheat plants. The data obtained during the study and analysis of varieties of winter soft wheat with the sign of multi-flower formation are given. The reproductive potential of winter soft wheat plants was determined by counting flowers at the VI stage of organogenesis. The examined multi-flower forms of soft winter wheat compared with Krasnodar breeding varieties showed increased reproductive potential, as well as an increased number of grains with the ear, but with a reduced mass of 1000 grains. According to the data obtained, the degree of the reproductive potential of multi-flower forms of winter soft wheat varied significantly, depending on the weather and climate conditions of the year of the study. In conclusion, the choice of multi-flower formation of winter soft wheat as a model object for investigating the reproductive potential of wheat, as well as the factors that influence its implementation and the extent of such influence is justified

MORPHOLOGICAL FEATURES AND SOWING QUALITIES OF SILYBUM MARIANUM (L.) GAERTN. VARIETY
Description
Distinctive features of seeds of Silybum marianum two varieties – the ‘Start’ and the ‘Debut’ on morphology are presented in the article and also data on influence of storage conditions on sowing qualities of seeds are submitted. Seeds of two varieties differ among themselves on coloring, a form and mass of 1000 seeds. The ‘Debut’ is characteristic sign of a variety existence of dark strips on a surface of seeds. Results of two years of tests have shown that during 1 year from the moment of collecting seeds energy of germination and viability gradually increases and reaches the maximum values in 12 months independently of storage conditions. The viability of seeds of the Silybum stored at the room temperature within 18 months decreases by 8,5-12,5%. As a result of an experiment it has been established that in the conditions of not heated room successful storage of seeds is possible not longer than one year, after that sowing qualities of seeds sharply decrease

DEVELOPMENT OF SIGNIFICANT PHENOTYPICAL TRAIT MODELS OF TABLE GRAPE
Description
Intensive viticulture as a sub-branch of the grape-wine industry of agriculture is developing due to the introduction of modern scientific developments. The intensification of production consists of laying vineyards with planting material of higher biological categories, highly productive clones of traditional and long-established selection varieties; advanced agrotechnological techniques and mechanized operations, etc. For import substitution of table grapevine in our country, it is especially important to introduce new big-berry varieties from early to late maturity, providing a continuous 100-day conveyor for harvesting, with a bunch of grapes, various colors and the shape of berries. In many countries of the world with developed viticulture, breeding programs are being conducted to create competitive table varieties. As a result, there were obtained Muscat of Italy (Italy), Cardinal, Red Globe (USA), Moldova (Moldova), widely spread all over the world. But the world market does not stand still and breeders are working on new varieties. In recent years, there has been a trend of enlargement of berries from 8 to 24 grams, preference is given to varieties with pink and red berries. So, for example, created in Ukraine - a very early variety of Livia; in Russia - the variety clones of Livia K and Rochefort K, the early varieties of the Memory of the Teacher, the Gift of the Nesvetay, the Preobraghenie and the Jubilee of Novocherkassk, and others. These varieties are bred according to the developed model, which shows the genetic regularities of the formation of maximum expression in transgressive recombinants in quantitative (mass of berries and bunches) and qualitative (shape and color of berries) traits associated with maturation

Description
Chromium in soils is represented by the following forms of connections: 1) stationary; 2) strongly bound in the composition of primary and partially secondary clay minerals, with one and a half aluminum and iron hydroxides; 3) exchange bound on the surface of one-and-a-half oxides and clay minerals; 4) associated with organic matter of soils; 5) water-soluble compounds. The gross chromium content (70.1-78.3 mg/kg) in leached chernozem is well below clark soils of the world (100 mg/kg). The share of mobile, acid-soluble and acid-insoluble forms of the element compounds is 0.01, respectively; 7.09 and 92.9 % of its gross content. After three rotations of 11-full grain-grass-tillage crop rotation without mineral fertilizers, the chromium content in leached chernozem has not undergone significant changes, even to some extent there is a tendency of its reduction. This indicates the absence of serious natural sources of chromium in the soil. Scientifically-based system of fertilizers for agricultural crops does not lead to anthropogenic pollution of leached chernozem with chromium. The removal of this element with crop yields is compensated by its receipt in the form of ballast with mineral fertilizers
