With the help of constant visual control and spectral during the period 2021-2022, the development of a vineyard was followed, and the dynamics of climatic factors were followed. Monitoring of climatic parameters (air temperature, soil temperature, atmospheric humidity, leaf humidity, sunshine, wind direction, evapotranspiration, rainfall) was carried out throughout the growing season of the vineyard. As a result of the observations and reports, some conclusions were drawn related to the effectiveness of drone monitoring. The BNDVI indices, which range from 0 to 1, were measured, and soil and leaf moisture parameters were recorded throughout the growing season. During the drone survey, the dynamics of the vegetation index of the vine was tracked in the established field experiment. The results of the two-year research on yield and quality of grapes fully correspond and are linked to the influence of climatic factors during the growing season and the dynamics and course of phenophases. A difference was reported between the two years, both in terms of climate and grape and wine quality. Considering the non-uniform site and sloping terrain of the vineyard, it was concluded that remote monitoring data is an excellent tool for control, tracking and forecasting, but when considering a specific local site, professional visual inspection and the application of additional analyzes and performance of measures related to cultivation technology.
