Green nanomaterials are increasingly used to improve plant growth and phytochemical traits. This study employed Eucalyptus globulus leaf extract, a medicinal plant, as bio-reductant capping agent synthesize copper oxide nanoparticles (CuO-NPs), which were applied seed primers for Lactuca sativa (lettuce), an annual species prized its short germination time rich bioactive compounds. Characterization of CuO-NPs using FTIR, XRD, SEM, EDX confirmed their purity, crystalline structure, average particle size 74.66 nm. The at concentrations 0.01 mg/ml, 0.02 0.03 0.04 mg/ml. At the highest concentration (0.04 mg/ml), significant reductions in physical parameters observed, with length, height, width measuring 7.85 cm, 5.50 3.48 respectively, compared 13.70 11.52 11.18 cm control plants. Phytochemical analysis identified tannins, alkaloids, phytosterols, saponins, flavonoids, glycosides all methanolic extracts, while carotenoids absent higher (0.03 mg/ml mg/ml) due phytotoxicity. FTIR revealed prominent peak 858 cm⁻¹ indicating presence antioxidant-rich aromatic phenyl In conclusion, demonstrates that synthesized extract enhance constituents optimal but inhibit reduce key phytochemicals doses. Future research should optimize nanoparticle minimize phytotoxicity maximizing beneficial effects on
