The work is devoted to studying the nature of the influence of individual abiotic factors of the southern territories of Russia on the features of the formation of an economic apple yield in adjacent years and the justification of the possibility of adjusting the course of this process in adverse environmental conditions. The studies were carried out in 2018-2019, which are distinguished by the manifestation of weather anomalies in the summer-autumn period. Field experiments were performed at the farms of the Kuban horticultural zone on soils suitable for planting fruit stands: leached and typical chernozems. The features of the development of plants of apple trees of winter varieties Kuban crimson and Fuji on the stock M9 were studied. In the experiments, an option is provided using foliar treatment of plants with Pomaset fertilizer. The effectiveness of the formation of the economic apple crop depends on the biological characteristics of the used pomological variety, as well as the temperature and moisture conditions during the growing season of the plants. Soil conditions do not significantly affect the course of this process. The probability of losing the potential apple crop at the XII stage of organogenesis (pre-harvest decay) under the influence of abiotic summer stressors: high air temperatures and water deficiency is noted. With the manifestation of extremely high air temperatures in late summer and during the autumn months, a significant increase in the duration of vegetation of various (especially strong-growing) apple varieties was recorded, causing a shift in the process of differentiation of generative buds (stages III-IV of organogenesis) to a later date, and, as a result, - decrease in potential plant productivity in the next season. With the manifestation of abnormal weather conditions, the prospects of foliar treatment of trees in the second half of the growing season with Pomaset fertilizer, which optimizes the fruiting of the apple tree in adjacent years, are shown. At the same time, the fruit yield in the current year is increasing by 9-14%, and in the next season - by 7-10% in comparison with the control values
Common lilac (Syringa vulgaris L.), is one of the most essential landscape plants throughout the whole cool and temperate region and also in Finland very popular and traditional ornamental. The diversity of the lilacs available for research use and growth in Finland could be broadened by introducing Russian winter hardy cultivars to Finland. Their winter hardiness and survival in the Finnish climate has to be studied in order to proceed to using Russian cultivars in the Finnish climate. Lilacs that grow at the Central Siberian Botanical Garden Siberian Branche of the Russian Academy of Sciences at Novosibirsk were introduced to Finland within the framework of the collaborative project in 2012. Currently, the collection of Syringa vulgaris in CSBG SB RAS has 26 cultivars of 116 tested ones, most resistant to the conditions of Novosibirsk city. In project “Syreenimaja” (2016-2018) small scale plantations with Russian lilac cultivars were made at several locations in Finland and the freezing tolerance of the cultivars was tested. The survival and growth of the lilac plants in these plantings in landscape gardening areas in old gardens is being observed. The lilac plants are still young and have not been flowering broadly. The preliminary results have shown that the Russian lilacs have potential to grow in Finland, but at least cultivar ‘Daphna’ has suffered from winter injuries. Descriptions of 10 tested lilac cultivars from the collection of the CSBG SB RAS are given
The study was carried out with the financial support of the RHNF as part of the research project of the RFBR 17-02-00475-OGN "Application of metaheuristic algorithms for solving direct and inverse problems of optimizing the management of spatially distributed complexes"). The article considers the issue of automated selection of specialists for the project. It is proposed to use artificial neural networks as a decisive core of the system. We have considered several solutions to the problem with a basic version based on a cascade of two neural networks
Diseases of the digestive system are one of the huge problems of veterinary medicine and pharmacy. This group of diseases not only affects all age groups of animals, but can occur even in newborn puppies. It is very difficult to talk about the breed predisposition to pancreatitis in animals. Pancreatitis occupies one of the leading places in the structure of digestive diseases in animals. The urgency of this veterinary problem is increasing every year. Acute pancreatitis manifests itself suddenly, most often against the background of gross violations in feeding, with the disease of the duodenum and gallbladder. In this case, there is a violation of the outflow of secretion into the ducts of the pancreas. In the tissues of the pancreas there are diffuse changes up to necrosis. Severe inflammation of the pancreas leads to a sharp deterioration in the general condition of the body, sharply reduced blood pressure. The animal is in great pain, vomiting is observed. The animal needs urgent care. The disease can be chronic. Periods of exacerbation are repeated from time to time. The owners usually do not call veterinary specialists. Since the disease is manifested by symptoms characteristic of many pathologies of the gastrointestinal tract, it is therefore difficult to diagnose. In the history of the animal there are both diarrhea and constipation, the animal has a reduced appetite, in hotel cases there is cachexia. In hematological studies, we can note an increase in sugar levels. Therefore, for the differential diagnosis of the animal, we carry out ultrasound, x-ray diagnostics all together with biochemical methods of blood tests. In the future, when choosing treatment tactics, all diseases that could accompany inflammation of the pancreas are taken into account

To assess the impact of investments on the results of the Agro-industrial complex, we use an adaptive management system for open systems
The article presents results of studies on the intraspecific structure of the population of blast causative agent using sets of tester varieties from International Rice Research Institute - IRRI. The differentiation of the fungus population on tester varieties is the most progressive, since it allows one to determine the virulence genotypes of races of pathogens and identify the resistance genes of rice plants effective for them. The work has studied the diversity of blast causative agent in released rice varieties by morphological and cultural traits. Currently, in the world, the resistance of rice plants to blast is becoming one of the important indicators of the competitiveness of varieties. The basis for the successful rice breeding for resistance to blast is the availability of source material with a fairly wide spectrum and a high level of resistance. Resistance donors are selected based on the identification of genes that control this trait in rice
The main component of agricultural production is machinery, which is a complex technical system (harvesters, agricultural machines, tractors, cars, etc.). The practice of operation of technically complex machines shows that, in general, the process of replacing worn parts and working devices of agricultural machinery with new ones prevails, and the number of restored products is small. However, experience shows that the technological process of restoration of machine parts allows you to get high quality surfaces of such parts and reduce the cost of repair. One of effective methods of restoration of surface layers of details is gas-flame spraying with the subsequent laser reflow. The article presents the results of the study of the zone of thermal influence in steels U8A and St3, as well as the influence of laser reflow regimes on its microhardness in these steels. It is established that the higher the laser power and the lower the speed of movement of the optical head, the larger the size of the thermal influence zone. Conversely, the lower the power of the laser and the higher the speed of movement of the head, the smaller the size of the zone of thermal influence. The power of the laser and the speed of movement of the optical head slightly affect the value of microhardness. It was also noted that promising areas in the field of restoration of parts of agricultural machines laser welding are: a scientific rationale for the selection of powders; the study of regularities of changes of the microstructure parts, regularities of formation of layers; development of modes and justification of regimes of welding; and, ultimately, the development process of restoring the specific parts
