| Summary: | Nanotechnology has been a source of innovation in various fields in recent years, and its application in agriculture has attracted much attention, particularly for its potential to enhance crop growth and optimize nutritional quality. This study systematically investigated the effects of nickel ferrite nanoparticles (NiFe<sub>2</sub>O<sub>4</sub> NPs) on peanut (<i>Arachis hypogaea</i> L.) growth, nutrient dynamics, and biochemical responses, highlighting their potential as sustainable alternatives to conventional fertilizers. The results showed that an optimum concentration of 50 mg/kg soil significantly improved photosynthetic efficiency, biomass accumulation, seed yield, and nutritional quality, with 1000 seed weight and total yield increasing by 12.3% and 15.6%, respectively. In addition, we hypothesized that NiFe<sub>2</sub>O<sub>4</sub> NPs would activate the antioxidant system and increase plant resistance. According to the risk assessment, the target hazard quotient (THQ = 0.081) is well below the safety threshold of 1. These findings provide strong evidence for the application of NiFe<sub>2</sub>O<sub>4</sub> NPs as next-generation nano-fertilizers, offering a dual advantage of improved agronomic performance and biosafety. However, further research is needed to optimize their application strategies and assess potential long-term environmental impacts. |
