The paper studies the reliability of transmission lines of Michurinsk district electric lines in Tambov Region. It evaluates the quality of overhead power transmission lines in the support-insulator-wire system and determines the reliability factor of overhead lines. The paper proposes methodological approaches to the survey of power transmission lines using unmanned aerial vehicles. Their use seems quite promising and profitable, since the cost of such work is an order of magnitude lower.

The authors analyze the results of tree taxation of different apple trees varieties on the territory of I V Budagovsky research and development center at Michurinsk State Agrarian University. The plantation valuation and the establishment of locality class were carried out using the methodology of Michurinsk State Agrarian University. Studies have shown that class quality of the garden can be characterized as high – from 85 to 100 points, which corresponds to the first class of quality. Thus, all graft-rootstock combinations are normally developed, while it was found that within the studied population for a number of graft-rootstock combinations the percentage of normally developed trees is on the verge of transition to a lower quality class. The authors proposed a method for developing a program to automatically determine the state of each tree based on using digital recognition technology, the proposed technology will significantly reduce time and labor costs and exclude the subjective assessment factor.

The article discusses the impact of radiation treatment of agricultural products on their chemical composition, which determines the nutritional value of products, as well as on the main properties of products. The main advantages of agricultural products that have undergone radiation treatment are given, related, inter alia, to an increase in their shelf life, prevention of diseases and insect damage. The world experience of increasing the volume of radiation processing products by type in comparison with the 2010 level is considered. The main criteria for radiation processing of food products and the levels of radiation doses required for absorption by products to achieve certain technological goals are presented. The influence of radiation doses of radiation on proteins, fats, carbohydrates and vitamins in agricultural products is indicated. The influence of radiation exposure on the growth and maturation of some crops is estimated. The possibility of the influence of changes in the structure and composition of irradiated food products on the human body is emphasized. The factors that ensure the profitability of farms that use the practice of radiation processing of agricultural products when supplying them to international markets are also given. The calculations are carried out on a model of a small farm specializing in the cultivation of cucumbers and tomatoes.
