Soil salinization threatens global agriculture, reducing crop productivity and food security. Developing strategies to improve salt tolerance is crucial for sustainable agriculture. This study examines the role of organic fertilizer in mitigating stress rice (Oryza sativa L.) by integrating NDVI metabolomics. Using salt-sensitive (19X) salt-tolerant (HHZ) cultivars, we aimed (1) evaluate changes metabolite content under stress, (2) assess regulatory effects fertilizer, (3) identify key metabolites involved response fertilizer-induced regulation. Under survival rate 19X plants dropped 6%, while HHZ maintained 38%, with increasing 25% 66% HHZ. values declined sharply (from 0.56 <0.25) but remained stable (~0.56), showing a strong correlation (R2 = 0.87, p < 0.01). provided dynamic, non-destructive assessment health, offering faster more precise evaluation than analysis. Metabolomic analysis identified 12 metabolites, including citric acid, which well recognized regulating tolerance. HTPA, pipecolic maleamic myristoleic acid have previously been reported require further study. Additionally, seven novel metabolites—tridecylic propentofylline, octadeca penten-3-one, 14,16-dihydroxy-benzoxacyclotetradecine-dione, cyclopentadecanolide, HpODE, (±)8,9-DiHETE—were discovered, warranting investigation. Organic alleviated through distinct metabolic mechanisms each cultivar. In 19X, it enhanced antioxidant defenses energy metabolism, oxidative damage improving fatty metabolism. contrast, primarily benefitted from improved membrane stability ion homeostasis, lipid peroxidation stress. These findings support identification screening cultivars also highlighting need cultivar-specific fertilization optimize resilience performance. Based on analysis, 26 out 53 differential were significantly correlated NDVI, confirming association between shifts application. By metabolomics, this provides refined method evaluating responses, capturing early salinity biomarkers. approach may prove valuable application variety screening, precision farming, contributing scientific future improvement agricultural resilience.
