BIOTECHNOLOGY OF IMPROVEMENT AND PRESERVATION OF NATIVE DON GRAPE VARIETIES
06.01.01 General agriculture, crop production (agricultural sciences)
DescriptionThe article presents the results of microclonal reproduction and recovery of native grape varieties, the creation of basic nursery. In addition to the culture of apical meristems, we have developed a chemotherapy using salicylic acid. A method of decontamination of plants from mycoplasma infection has also been developed, which includes the introduction of the antibiotic Cefotaxim in the nutrient environment at a concentration of 50 to 450 mg/L, depending on the degree of infection of plants. Adding to the nutrient medium of the drug Emistim reduces the death of meristems from infection by 3-5 times, improves their differentiation. The use of the drug Melafen helps to improve morphogenesis and quality characteristics of plants. The high survival rate of meristems during adaptation to non-sterile conditions has been noted. Biological testing on herbaceous indicators showed no chronic diseases. Plants after adapting to non-sterile conditions are planted, in the form of vegetative seedlings with a closed rootsystem, on the basic nursery. The survival rate of plants was 70-80%, in some varieties it is higher: 96.4% (Sypun black) - 98.6% (Krestovsky). It has been proved that in vitro clonal microbreeding there is no change at the genetic level even after 8 years of cultivation, which confirms the reliability of the developed technology of reproduction and recovery of native grape varieties in vitro

FATTENING QUALITIES AND MEAT PRODUCTIVITY OF SALSKAYA SHEEP BREED OF IMPROVED GENOTYPES
DescriptionImprovement of domestic breeds of Merino sheep remains an important task. The reorientation of the industry to wool-meat and meat-wool direction of productivity can contribute to the restoration of domestic sheep breeding. An example of such conversion is a relatively young breed called Dzhalginsky Merino, created in the Stavropol region on the basis of the Stavropol breed with the involvement of resources of domestic and world breeding. In the current situation, it seems relevant to use Dzhalginsky Merino, in order to improve the meat and wool qualities of sheep of domestic fine-wool breeds. Obtaining a new genetic combination of animals, formed by combining the genotypes of breeds Salsky, Stavropol and Dzhalginsky Merino will increase the efficiency of the industry in a market economy and will provide a more complete use of the productive potential of the breed. The results of studies on obtaining and use of animals, new genetic combinations of a wool – meat direction of productivity, with high energy of growth, meat and wool productivity, improves the efficiency of Merino sheep are an important theoretical justification for making a contribution to zootechnical science, with the aim of improving fine-wool breeds of sheep and can be used in practical work in the production of high quality lamb

SCORING SYSTEM BASED ON INFORMATION-COGNITIVE MODELING
08.00.13 Mathematical and instrumental methods of Economics
DescriptionOne of the key problems facing the credit institution is the late payment of the loan. Firstly, it is a deeper analysis - in order to be carried out “manually” it is not even required several days, but weeks. Secondly, it allows you to work with clients much faster. And most importantly scoring allows you to negate the influence of the human factor. An automated system, no matter how you look, cannot be liked or not. Data analysis is only based on facts. Scoring is beneficial to all. The bank is able to work faster and reduce the risk of loan defaults. Clients, in turn, can apply for a loan on terms that are more favorable

ALGOLOGICAL MONITORING OF VARIOUS TECHNOLOGIES OF MAIZE CROPS PRODUCTION
06.01.01 General agriculture, crop production (agricultural sciences)
DescriptionThe article studies species composition and abundance of soil algae under hybrid Krasnodar 292 AMB cultivated with various technologies. 7 species of cyanobacteria and 11 soil algae were revealed. It was revealed that the highest total amount of algae was observed in variants of environmentally acceptable and intensive technology, which is associated with the positive effect of mineral fertilizers and the consequent application of organic matter on soil algal flora. However, in these variants a decrease was observed both in the number of species and in the abundance of green and yellow-green algae. The species Botrydiopsis arhiza Borzi was absent or found in insignificant amounts. The species composition was less diverse, which can be attributed to the negative effect of the herbicide used in these technologies. The method of tillage had practically no effect on green, yellow-green and diatoms. An increase in the intensity of soil cultivation had a significant negative effect on both the species composition and the number of cyanobacteria

MAINTENANCE AND USE OF BREEDING COWS OF THE HOLSTEIN BREED IN THE CONDITIONS OF INTENSIVE TECHNOLOGY
DescriptionConsidering the fact that in Russia the development of dairy cattle breeding is based on increasing milk production in terms of providing this product, the further increase in milk yield and quality of cow's milk remains important. Some farms in Russia, including the Krasnodar region, have reached high milk production rates in whole herds of up to 12-13 thousand kg of milk per cow. Today it is important to “propagate” such farms. To achieve this goal, it is necessary to study their livestock breeders experience, approaches to the selection of cattle (calves, heifers, cows), to form herds of animals that can get high milk yield under the conditions created for them. The farm in which we conducted our scientific research is distinguished by the fact that much attention is paid to maintaining a high level of breeding and breeding, as well as to creating optimal factors for keeping, feeding and caring for animals. Agroholding Step includes 5 farms in divisions: one in the Kuban Step, two in public company of shareholders “Rodina” and two in shareholder company “Novoplastunovskaya” Three farms are located in the village of Chelbasskaya, where the cowsheds were reconstructed and equipped with new equipment. In the village of Novoplastunovskaya, new buildings were built in the territory of the old farm, and the 4th farm was built in 2018 in the new territory. All farms contain highly productive breeding cows of the Holstein breed. The Russian information programs “Selex-Dairy Cattle” and Israeli program “AfiFarm” were introduced. We have studied zoohygienic conditions in various buildings of dairy farms in the spring, where animals are constantly kept. The results obtained indicate that the cows are kept in comfortable conditions, allowing them to eat a balanced diet in accordance with their needs and to avoid many stresses what is important for the secretion of milk. Indicators of genetic potential for milk production of cows and the effectiveness of its manifestation are also determined

Description
The article discusses the relevance of the use of protected amino acids (lysine and methionine) in animal husbandry of the Krasnodar region, using the example of the farm "Krasnodar". The highest milk yield was obtained from cows with the combined addition of lysine and methionine in their diet. In relation to control (CR), the average daily milk yield in the group with combined additives (CR+L+M) was 38.4 kg/day. In addition, there was a positive effect of lysine and the combined additive (CR+L+M) on protein and fat in milk. Protected methionine (CRM) had no effect on the yield of fat and protein in milk. It was noted that additives of protected amino acids in groups with lysine and combined amino acids reduced the cost of dry matter (DM) and metabolizable energy (ME) per kg of milk. The results of our studies have shown that the productive milk response and its components are affected by the amount of the first limiting amino acid in the diet. Also, the supply of protected lysine changed the plasma concentration of animals and improved the availability of amino acids for milk protein synthesis

DescriptionThe 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
