For high plant growth and efficient production, manufacture of new nano-fertilizers is an important strategy to repair the nutrients shortage. Copper ferrite nanoparticles (CuFe₂O₄ NPs) were manufactured via co-precipitation method with the aim to understand the role of different concentration of them (0.0, 0.04, 0.2, 1, and 5 ppm) on growth, chlorophyll content and antioxidant enzymes activities of cucumber plants grown in hydroponic system. The prepared sample was studied by various mechanisms such as: X-ray diffraction (XRD), Infrared spectroscopy and vibrating sample magnetometer. XRD pattern implies the nanocrystalline nature of the synthesized sample, where the crystallite size is 30.7 nm. Exposure to CuFe₂O₄ NPs caused an increase in the fresh weight and protein content of cucumber plants. Also, superoxide dismutase and peroxidase activities of cucumber shoots and roots were significantly increased. The uptake of Fe and Cu by cucumber tissues was significantly enhanced by application of CuFe₂O₄ NPs.
