STUDYING A DISK SOWING DEVICE AND JUSTIFICATION OF ITS PARAMETERS
05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
Description
In recent years, in the conditions of the Tambov region, thanks to the widespread introduction of innovative technologies, the yield of root crops of this culture has significantly increased. The scheme of sowing is the basis of technology of cultivation of any crops depend on the productivity and quality of products, material and monetary and energy costs, density of sowing, supply area and design features used cars. According to academician V. I. Edelstein, the optimal sowing scheme is able to provide an increase in crop yields up to 40%. It was noted that the most optimal scheme of sowing is a tape, with the use of which it is possible to achieve a reasonable compromise between the possibility of rational thickening of plants in order to increase yields and improve the working conditions of agricultural machines. The relevance of the research lies in the modernization of the sowing apparatus of the beet seeder SST-12B, under the belt scheme of sowing with a staggered arrangement of plants in two adjacent lines of the tape and the study of its design parameters. The analysis shows that with an increase in the angle of installation of the scraper over 60 degrees, there is an increase in the percentage of occupancy of the disk cells with seeds in all studied hybrids. Studies have found that the hybrid RMS-120 at the angle of installation of the scraper 70 degrees is 100 percent filling cells with seeds, while hybrids XM-1820 and Troika cells filled only 93.3%. This is due to the fact that the seeds of the domestic hybrid were more aligned in diameter compared to the seeds of foreign firms. It should also be noted that the hybrid RMS-120 with a scraper angle of 70 degrees was marked by the lowest damage dragees-0.67%, while hybrids XM-1820 and Troika values of this indicator were 0.83 and 0.73%, respectively. By increasing the angle of installation of the scraper over 80 degrees, the percentage of damaged seeds increased from 0.4 to 0.66%

05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
Description
As a result of the analysis of the scientific question, there is a steady trend of growth in food consumption, especially of plant origin. To this issue, it is also necessary to add the provision of food security of the country and the exclusion of dependence on foreign producers. Thus, before science and production is a serious question of a significant increase in the production of crop products with a slight increase in the cost of these types of work and the main thing is to ensure the preservation of soil fertility. This can be achieved by reducing the use of chemical means of protection, less intensive impact on the treated environment by the running systems of power facilities and the working bodies of machines, but in compliance with the primary requirements for the treated surface. The proposed design of a horizontally arranged spherical disk working body can be used in various tillage machines for shallow and surface tillage. The design of the working body allows reducing the passes of the unit to perform the necessary agricultural requirements for equalization and ridges of the soil. And these indicators have a significant impact on the quality of sowing, which will necessarily affect the yield in the end. Comparative studies of the proposed working body and the same devices used in production show a clear advantage of the new scheme

Description
The article presents the results of studies on the influence of the conditions of the Piedmont horticulture zone of the Krasnodar region and the shape of the crown on the productivity of apple trees. Objects of study were trees of winter apple varieties Idared and Renet Simirenko grafted on MM 106 rootstock. The trees were planted according to the 5 × 3 m pattern. In the eighth year, the rounded crowns were transformed into flattened across the row (from the eastern and western sides of the tree) to crown width 2.0 ... 2.5 m. Orientation of rows was from east to west. The garden is located on the northern slope with a slope of 3 degrees. Scheme of experiment: option 1 - sparse-tier crown (control); option 2 - flattened crown. In the experiment, 2 variants; in each variant, 10 typical trees were taken. Repetition tree plot. The place of the experiment is Abinsky district of the Krasnodar region. Agrocounts of indicators of fruiting of apple trees were carried out according to generally accepted methods, statistical processing of research results was carried out by the method of analysis of variance described by B.A. Dospekhov. The results of our studies showed that flattening the crown of apple trees contributes to an increase in the number of fruits formed on them per unit volume of the crown in the variety Idared to 10.1 kg or 1.87 times, and per m2 of the projection of the crown to 15.5 kg or 1.72 times more than crowns without flattening. In the variety Renet Simirenko, the number of fruits according to the same indicators increases by 1.86 and 1.74 times. Also, when flattening crowns, the yield of apples from one tree in the Idared variety increases by 9.6%, and in the Renet Simirenko variety decreases by 7.7% compared with the control

Description
The article studies the effect of various agricultural practices on the yield of two sunflower hybrids (Fortimi and N4LM 408) in the experiment. The studies were carried out in the central zone of the Krasnodar Region on the experimental fields of the JSC "Agrocomplex", Vyselkovsky district in 2018-2019. The experience was laid down according to the triple experience scheme (factor A - the primary soil cultivation techniques; factor B - sunflower hybrids; factor C - herbicides). It was found that with the change of technology (the method of soil preparation and the use of herbicides), the weed infestation of crops changed and a minimum number of them was noted on the variants where postemergent herbicides were used (Euro-Laytning and Hermes). The maximum yield was obtained using chisel and disk plowing with the treatment of sunflower crops with the herbicides Euro-Light and Hermes. There was an increase in yield compared with plowing and these changes are mathematically valid

PRÉVALENCE ET IMPACT ÉCONOMIQUE DES STRONGLES GASTRO-INTESTINAUX DES CAPRINS AU NORD DU BURUNDI
Description
Une enquête et une étude parasitaire des caprins ont été réalisées dans les trois provinces du Nord du Burundi appartenant aux régions naturelles de Bweru, Bugesera, Buyenzi et Mugamba. L’étude montre que le système extensif combinant le gardiennage et l’attachement au piquet vient en première positon (44%) par rapport au pâturage au piquet (28%). Les résultats montrent que 75,84% des éleveurs font l’élevage des caprins spécialement pour les vendre, 22,15 % pour la production du fumier et 2,01% pour l’autoconsommation. L’enquête sur 424 chèvres pendant la saison pluvieuse et sur 538 chèvres pendant la saison sèche effectuée sur 150 ménages montre une dominance des caprins de race locale (78,4%) par rapport aux races exotiques et croisées (21,6%). L’analyse coprologique a montré la présence des strongles gastro-intestinaux de genres Ostertagia, Chabertia, Haemoncus, Paramphistomum, Nematodirus, Bunostomum, Dictyocaulus, Oesophagostomum, Trichostrongulus, Cooperia, Diclocoelus et le genre Toxocola. Les genres Ostertagia et Chabertia étant dominants avec 20.10% et 18.76% respectivement. Les jeunes chèvres de moins d’une année étant significativement plus infestées par les strongles gastro-intestinaux que les chèvres adultes (p< 0.05). Ce parasitisme gastro-intestinal affecte négativement l’économie des éleveurs par des dépenses liées aux traitements. Il se traduit aussi par une réduction de leur croissance voire une mortalité lors d’infestation forte et influence négativement sur le gain du poids de l’animale et sa croissance en générale (p=0.001)

MORPHOLOGICAL AND CHEMICAL PARAMETERS OF OSTRICH EGGS
Description
The article carries out an analysis of morpho-chemical parameters of ostrich eggs when l-carnitine is included in the diet. Studies were conducted on two groups of ostriches: I-received a standard diet, II-to the standard diet received L-carnitine at a rate of 300 mg per 1 kg of feed. From April to August we were studying the ostrich egg production, morphological composition of eggs, chemical composition of albumen and yolk, the amino acid composition of egg yolk, the level of cholesterol, fatty acids including saturated, unsaturated and polyunsaturated. It has been determined, that L-carnitine increases the egg production of ostriches by 24%. The weight of protein in the groups was 56.9-56.2%; yolk-27.6-26.7%; shell-16.4 -16.2%. The amount of cholesterol in the egg yolk of the 1st group ostriches was 12.2 mg, in the 2nd one it decreased by 7.4% (P>0.95) and amounted to 11.3 mg per gram of yolk. The level of amino acids in the egg yolk of the 1st and 2nd groups was approximately equal. The number of fatty acids in the 1st and 2nd groups was: saturated 39.5 and 39.7%, monounsaturated 49.99 and 49.80%, polyunsaturated 10.37 and 10.47% respectively. The sum of unsaturated and polyunsaturated fatty acids in ostrich eggs was 60.36 - 60.27%. The sum of ω3 and ω6 fatty acids is 10.18 and 10.25%. Ratio ω3: ω6-1: 3,3. The ratio of polyunsaturated to saturated acids was approximately 1:3, and polyunsaturated + monounsaturated to saturated-1.52 units (approximately 1.5 : 1).

08.00.13 Mathematical and instrumental methods of Economics
Description
The article provides a comparative analysis of assessments of the socio-economic development of the Krasnodar region from such well-known rating agencies as Standard & Poors, Moody’s, Fitch Ratings, which belong to the United States of America. The studied ratings are compared with the ratings of the national agency of the Russian Federation called “Expert RA”. The values of the established ratings are examined, as well as number of possible reasons why the ratings of the United States of America differ from the ratings of the Russian Federation, for example, economic and political reasons, and, subsequently, how these ratings affect the investment attractiveness of the Krasnodar region. The article explains positive and negative aspects of the integrated methodology used by international rating agencies, consisting of software and expert opinion, the level of access to it for study and analysis. We study another (local) source of information on the investment attractiveness of the Krasnodar region, which is a state institution, namely the Department of Investments and Development of Small and Medium Enterprises of the Krasnodar region. Options are proposed for improving the system of analysis of statistical data through methods that are based on a clear mathematical approach to provide an adequate assessment of the region and municipalities without the influence of subjective expert opinion
