The study investigated the influence of varying concentrations of magnesium nanoparticles on the biochemical and physiological attributes of bambara nut (Vigna subterranea). The experimental set up involved applying different nanoparticle concentrations (measured in parts per million – ppm) to petri dishes containing inoculated seeds with observations recorded on the 7th day after inoculation. Results showed that lower concentrations of magnesium nanoparticles positively affected seed emergence, survival rates, and plantlet growth for both SUAN and TORFAM seeds. Specifically, SUAN seeds exhibited improved emergence and growth up to 25 ppm, while TORFAM seeds showed positive responses up to 100 ppm. However, higher concentrations (50 ppm and 100 ppm) had adverse effects on seed germination and seedling development, indicating a dose-dependent relationship. Further analyses demonstrated that nano treatments influenced plant biomass, moisture content, chlorophyll, protein content, as well as sugar and lipid contents in seeds. Nano-100 treatment significantly enhanced chlorophyll and protein content in plant leaves, while also increasing sugar and lipid contents in seeds compared to other treatments. These findings provide valuable insights into the potential applications of magnesium nanoparticles for crop enhancement, highlighting the importance of dosage considerations in agricultural practice.
