The successful cultivation of vines must be aware of the phenological phases during the growing season. However, conventional phenological measurements on the ground are limited due to their spatial coverage. The use of Sentinel-2 imagery has led to an increased interest in its application to viticulture, with the data providing access to global spatial coverage and the potential for high temporal resolution. The present study was conducted during the period 2021-2022 in the experimental vineyard of the Agricultural University of Plovdiv, with the aim of studying the phenological phases of the wine grape varieties Merlot, Mavrud and Chardonnay. The results will enhance the interpretation of the spatiotemporal dynamics between meteorological data, vegetation indices (Normalized Difference Vegetation Index Normalized Difference Vegetation Index - NDVI), and phenological stages in vine cultivation. This study highlights the effectiveness of remote sensing for monitoring vineyard phenology, both retrospectively and in real time, as a valuable tool for maintaining high-quality standards in precision viticulture.
