The research carried out in Santa Ana, Ecuador, seeks to correlate the Normalized Difference Vegetation Index (NDVI) with the Green Chlorophyll Index (GCI) in different phenological stages of corn, taking advantage of remote sensing through photogrammetric flights using the eBee drone. The results show a positive relationship between GCI and NDVI in all evaluated phases of crop growth, with outstanding coefficients of determination (R²): 0.9138 in the V5 state, 0.8912 in the V11 state, and 0.8461 in the VT stage (flowering). These values support the efficacy of the GCI as a reliable indicator of health and chlorophyll content in maize, despite slight variations by stage of development. These findings enrich scientific knowledge and provide valuable insights for implementing remote sensing in sustainable agricultural management and informed decision-making in agricultural production.
