Abstract
Agriculture, being a labor-intensive sector, plays a crucial role in ensuring food security. Scientific advancements have rapidly influenced various fields, including agriculture, with significant impacts on genetics, plant science, environmental studies, climate research, land management, machinery, technology, and remote sensing. These advancements have resulted in improved resource management, leading to a reduction in food crises and famines. The focus of the study was on utilizing satellites images to monitor changes in vegetative growth grapevines, specifically using Sentinel-1 and Satellites-2. The study confirmed the effectiveness of these satellites data in accurately monitoring leaf changes by analyzing the VH and VV bands of Sentinel-1, as well as the NDVI bands 8-4, 5-6, 5-7, and 5-8a of Sentinel-2. The relationships between these bands and leaf changes showed significant values of 0.72, 0.42, 0.51, 0.51, and 0.52, respectively. However, lower accuracy was observed for chlorophyll. These findings highlight the high precision of satellites in monitoring changes in vegetative growth of grapevines and underscore the importance of developing improved techniques for monitoring and analyzing chlorophyll. That leads in future, to apply pressing Agriculture.
