| 520 | _ | _ | |a Detection of stress effects in crops is crucial for sustainable agriculturalpractices. Sun-induced fluorescence is a promising tool for monitoring thephotosynthetic activity of plants and crop health and has advantages overtraditional vegetation indices to be sensitive to plant changes. In this study,we use high-resolution spectral data from the Hyplant airborne sensor to detectwater stress in arable crops and compare SIF over the vegetation indices- NDVI and PRI to determine sensitivity to changes in plant environmentalconditions. We analyzed SIF variations across different crop varieties andtreatments spatially and diurnally to detect water stress among plots. Weobserved higher SIF values in the summer wheat crop compared to winterwheat and beans wheat mixture, indicating better crop health and photosyntheticactivity. Lower SIF values are associated with stress conditions. Diurnalanalysis of SIF showed that the peak values are at midday relating to lightintensity and rising temperature and decreasing in the afternoon. ComparingSIF with NDVI and PRI showed that SIF is more sensitive to plant responsesthan vegetation indices. This study highlights the potential of using SIF as atool for the detection of water stress. In future research, integrating validationdata to characterize stress in plants would be more effective in monitoring andmanagement in agriculture. |
