During fieldwork, machines and technical personnel work almost to the limit of their capabilities, while there is an urgent need for comprehensive monitoring of the interaction of the "Human-machine-environment" system and the operating rules for improving the operational reliability of tractors. (Research purpose) The research purpose is in developing a prototype of an electronic digital system that will help the operator to control changes in operational factors for improving the reliability of the entrusted equipment. (Materials and methods) The article presents conducted research on the use of the Galileo Sky+ terminal, which works together with additional programmable contactless sensors. This made it possible improving the system for increasing operational reliability. (Results and discussion) The article present examples and describes the accounting process for the human factor in the Human-machine-environment system. Authors have found that using the monitoring helps the operator and owner in reducing the share of subjective assessments in the efficiency of tractor operation and the readiness to work. (Conclusion) Using the proposed solutions for improving monitoring of the "Human-machine-environment" system will minimize the negative impact and risks of failures caused by the human factor in the operation of equipment. According to preliminary expert estimates, the efficiency of using the system will reduce operating costs and prevent gross errors in the operation of tractors.

An analysis is given and proposals are presented to increase the level of maintenance during the implementation of Federal Law No. 297-FZ by improving the testability and adaptability to diagnosing resource-determining units of domestic energysaturated equipment.

The genetic resources of wild populations of Medicago falcate L. of the Cretaceous South of the Srednerussky Upland in ecotopic conditions of chalky slopes and floodplain meadows in the basins of small rivers Tikhaya Sosna and Manjokha were studied to find the source material for breeding work to create varieties for different cultivation conditions. Evaluation of phytocenotic features, density of cenopopulations, forage and seed species was carried out. The species M. falcata forms, both on meadows in floodplains and on chalk slopes, full-membered normal cenopopulations, which have a continual (continuous) distribution of individuals by age groups, stable in time and in space. The centralized ontogenetic spectrum indicates the stable status of M. falcata cenopopulations in plant communities in various ecotopes of small river basins. The density of individuals of M. falcata was on average 18.9 % higher in cenopopulations of floodplains than in chalk slopes. The density of generative individuals in all studied cenopopulations was on average close and varied within 81.2-83.7 %, which indicates their stability in time and high adaptive potential. The weight of one fruiting model plant of floodplain meadows was 2.28 times higher than on chalky slopes. Seed yield on floodplain meadows was 2.02 times higher than on chalky slopes. Valuable source material for breeding M. falcatum varieties adapted to different ecotopic conditions was obtained.
