Resumo
This study investigates the effects of Fe3O4 nanoparticles (NPs) on nodulation, nitrogen
fixation, and growth of common bean plants. Plants were exposed to Fe3O4 NPs, Rhizobium
inoculation, and Fe3O4 NPs + Rhizobium inoculation. Results showed that treated plants
exhibited improved symbiotic performance, with increased nitrogenase activity, nodule
leghaemoglobin, and iron content. Additionally, the number of active nodules per plant and
nodule dry weight significantly increased. Symbiotic nitrogen fixation was enhanced,
leading to higher shoot and root total nitrogen content. Treatment combining Fe3O4 NPs and
Rhizobium inoculation yielded the best results. Fe3O4 NPs were taken up by plants,
accumulating in organs including nodules. Moreover, treated plants displayed increased
root and shoot lengths, leaf area, and dry weights. Magnetization curves indicated the
accumulation of Fe3O4 NPs in nodules, enhancing symbiotic performance. The study
suggests a novel strategy for improving common bean growth through Fe3O4 NPs and
Rhizobium inoculation, offering potential benefits for sustainable agriculture, and reducing
nitrogen fertilizer use. These findings contribute to a non-genetic approach in legume
research, emphasizing long-term improvements in common bean growth and symbiosis
[1-2].
