Nano-fertilizers protect the soil from excessive addition of traditional fertilizers, enhancing efficiency elements and diminishing number additive fertilizers. The effect Fe2O3NPs-Boron (Fe2O3NPs-B), Fe2O3 NP-Humic Acid (Fe2O3NPs-HA) at 100, 150 250 ppm, Fe2O3, control (without any iron fertilizers) on vegetative growth, flowering, photosynthetic pigments, nutrient element content isozymes activity (peroxidase, superoxide dismutase polyphenol oxide) Gardenia jasminoides plants was investigated. Gamma-rays 25 kGy were conducted for promising synthesis Fe2O3NPs-B, Fe2O3NPs-HA. experiment carried out under greenhouse conditions during two successive seasons. results stated that Fe2O3NPs-B Fe2O3NPs-HA highest concentration (250 ppm) had a significant positive in all characteristics, activity. showed optimal result morphological biochemical characteristics. enzymes appeared treated with NPs-B followed by NPs-HA ppm. advantage nano-fertilizer usage may be summarized as saving unreasonable accumulation classic improving use parts reducing different fertilizers consequence their increased surface area nano-size.
