Published: September 2021

Abstract
In modern conditions in the agricultural sector, the priority is the training of personnel and the testing of their knowledge using digital technologies, as well as the development of the facilities and timely retraining of personnel. The essence of the digital transformation of agricultural education lies in the effective and flexible use of modern technologies for the transition to a personalized and result-oriented educational process. Digital transformation should not be seen as an end in itself, but as a means used to optimize the existing potential in an innovative way. The main goal of agrarian education is to improve the quality of personnel training for the agro-industrial complex that meets modern requirements. The productivity and profitability of animal husbandry is largely determined by the conditions of animal feeding, the herd management system and other technological aspects developed and implemented by specialists in the field of animal husbandry. In the field of training these specialists, there is an active search for new approaches. The article reveals the organizational and pedagogical conditions that determine the implementation of additional professional programs in the field of animal science based on professional standards. An important role in the formation and improvement of professional competencies belongs to additional professional education. In this study, considerable attention is paid to the theoretical component of the topic, namely, the importance of agricultural personnel as a strategic resource for the development of agricultural production is substantiated, and the characteristics of the key issues of digital transformation of agricultural education that determine human potential are given. The analytical research is based on the results of work on training personnel for the agro-industrial complex of the Novgorod region and its changes under the influence of the existing regional policy. The relevance of research carried out in this direction is confirmed by the result of joint work of agricultural universities and employers, thereby having a positive effect on personnel training, providing production with modern managers.

Abstract
The study is devoted to the analysis of the financial stability of companies in the third sector of the agro-industrial complex (AIC) using the models of Du Pont, Altman, Lis and Sayfullin-Kadykov on the example of enterprises in the Novgorod region. Bankruptcy is a situation in which a legal entity or individual is unable to pay off its existing debt. The relevance of this topic is determined by the fact that due to the complex epidemiological situation, the threat of bankruptcy has now become a reality for a large number of companies around the world. That is why an important task is to maintain the company’s solvency and strengthen its financial independence, which will ensure long-term sustainable growth of the company in the market and avoid its liquidation. To solve this problem, the authors carry out modeling of the financial stability and solvency of companies. At the end of the analysis, there are reserves for increasing and ways to improve the financial condition of companies in the third sector of the agro-industrial complex in the region.

Published: September 2021

Abstract
The tree-ring analysis makes it possible to carry out a retrospective assessment of the influence of various environmental parameters on the growth and development of woody vegetation, as well as to determine their contribution to changes in radial growth in the context of the life cycle. Based on the study of tree rings, the absolute and relative dating of the layers of wood growth is made, and it is also possible to reconstruct the events occurring in a given ecosystem and having an impact on a specific tree or plantation. Various methods and tools based on computer data processing are currently used to measure the width of annual layers, which allow measurements to be carried out in a semi-automatic mode, while saving time and increasing the accuracy of measurements. The article discusses one of such methods for studying wood cores based on digitizing the pattern of tree rings and a program for positioning points, which makes it possible to exclude the use of expensive laboratory equipment, while maintaining the necessary measurement accuracy.

Published: September 2021

Abstract
Local breeding tomato varieties released for cultivation in Armenia in the protected ground conditions have a relatively weak resistance towards disease and stress conditions, despite good taste and quality fruits indicators. This factor, among others, is the reason for the unprofitability of growing tomatoes in greenhouses, which in turn leads to an even greater intensification of production in terms of–pesticides use. The vegetative grafting of vegetable plants can be the problem solution, which helps to increase the disease resistance, yield and improve the fruits quality indicators. The effectiveness of grafted plants depends on the genetic rootstock potential. Collection accessions of tomato and eggplant lines have been evaluated for resistance to fusarium wilt using real-time PCR diagnostics. A preliminary phytosanitary assessment of collection accessions has made it possible to recommend the most disease-resistant samples for using as a rootstock for vegetative grafting. The grafted plants assessment according to a complex of agronomic characters has shown the advantage of using eggplant rootstocks comparing with tomato rootstocks.

Abstract
Alternative energy sources play a significant part in the development of modern electric power, agriculture and forestry. In accordance with the decree of the Government of the Russian Federation of 08.01.2009 1-p “On the main directions of state policy in the field of improving the energy efficiency of the electric power industry based on the use of renewable energy sources for the period up to 2035”, currently, due to the high level of environmental pollution, the use of electricity obtained using alternative sources is relevant. Since alternative energy sources are renewable, there is no need for additional raw materials that are needed to generate energy. Alternative sources of electricity are widely used for consumers who are located in a remote area from power lines and have the need to obtain not only single-phase, but also three-phase electrical energy. For the implementation of power supply to these consumers, a wind turbine is considered, which allows for long-term uninterrupted three-phase power supply. The main difference of this wind turbine is a device for stabilizing the rotor speed of an asynchronous generator, which is a combined synchronous machine with a common inductor.

Abstract
Energy saving in technological processes of agro-industrial complex is an integral part of the development of a market economy, since nowadays there is a total interest of suppliers and consumers in economical energy supply. At present, the concept of electromagnetic compatibility in matters of power quality assurance covers almost any type of interaction between various devices and systems using electromagnetic phenomena, as well as the interaction of these systems with living organisms. There is an increasing need to analyze the impact of energy losses on energy efficiency in general and the need to analyze additionally arising losses caused by a sharp deterioration in the power quality readings. At present stage, more accurate information is required about the state of the electrical networks modes to determine the level of losses and reduce the commercial component of losses. In this situation, power systems require more accurate forecasts of the load of distribution networks in order to achieve excellence in operation, planning the development of networks and optimization of energy resources management, but the process of high-quality compensation remains rather complicated due to the growth of distortions in low-voltage distribution networks. In contrast to the existing solutions, the authors of the article offer to introduce into the method (algorithm) for controlling a compensation device the operation of forecasting the value of active power of non-stationary non-linear load on the forthcoming period of the supply mains voltage according to the results of monitoring the change in the active power of the load during the previous periods and statistical processing of the data obtained.

Abstract
The purpose of the study was to research the activity of nucleolar organizers of blood lymphocytes in large white breed pigs in postnatal ontogenesis and during pregnancy. The prepared blood smears were stained with silver nitrate (AgNO3) and additionally stained with azur and eosin. By measuring the parameters of the nucleus and nucleolar organizers’ activity (AgNORs), the changes in the morphological and functional state of the protein synthesizing apparatus of blood lymphocytes in large white breed pigs in postnatal ontogenesis were evaluated. It was found that the area of lymphocyte nuclei in newborn piglets was 83.72±3.37 mm2. By the age of three months, the area of the lymphocyte nuclei of pigs significantly increased by 13.41% (p⩽0.05) and amounted to 96.69±2.57 mm2, at the age of six months this indicator was 15.78% more than at the age of three months (114.80±3.69), by the age of nine months the number of AgNORs significantly (p⩽0.05) decreased by 11.32% compared to six-month-old animals (101.80±2.97). From 1 to 4 units of AgNORs are detected in the lymphocyte nuclei. By the age of three months, the total area of nucleolar organizers’ zones decreased by 29.30% (p⩽0.05), and by the age of twelve months increased by 16.72% (p⩽0.05) compared to the previous age period. A slight increase in the area of the lymphocyte nucleus was observed in pigs after delivery by 9.15% (p⩽0.05). After delivery, the number of AgNORs in pigs significantly increased by 11.26% (p⩽0.05). During pregnancy, from 1 to 3 AgNORs were detected in pigs with a total area of 4.29±0.27 to 4.33±0.30 microns. Based on the conducted research, it can be concluded that the functional state of lymphocytes undergoes obvious changes in postnatal ontogenesis and during pregnancy, this can be seen in alterations in the area of their nuclei, the number and total area of AgNORs.
