The investigation aimed to evaluate the performance of two UAV-based systems for measuring solar-induced chlorophyll fluorescence (SIF) across different crop species, varieties, and developmental stages under field conditions. Measurements were acquired repeatedly throughout the growing season to assess temporal and crop-specific variability in SIF and to compare UAV-derived observations with complementary reference measurements.
