Abstrakt: Table grape is a crop with a high nutritional value and frequent control is a guarantee of high quality and yields. The application instruments and methods for remote monitoring in obtaining information on the status of the vineyard will allow farmers to respond adequately to changes in plant development and grape quality. The aim of this study is to use non-destructive methods, such as satellite monitoring in the prediction of phenological changes that occur in the vine crop. The object of the study is a commercial table grape vineyard Vitis vinifera cv Velika in the land of village Granit, Stara Zagora district, Bulgaria in the period 2021-2023. NDVI was calculated using data from Sentinel 2 satellite in the main growth stages. The physiological state of the vines and the growth behaviour in the crop were monitored. An analysis was made of the relationship between the dynamics of the growth and NDVI to predict the yields. [ABSTRACT FROM AUTHOR]
