Influence of Magnesium Oxide (MgO) Nanoparticles on Maize (<i>Zea mays</i> L.)

Abstract

An approximate revolution synthesis of magnesium oxide (MgO) nanoparticles has been prepared. For plant growth and development, MgO is essential. The effect and efficiency, respectively, in seed germination, seedling growth, and plant growth were also studied. These analyses examined maize with different concentrations and parameters. The concentration of 500 ppm was tested with extreme results in areas such as plant height, protein contents both in-vivo and in-vitro, and MgO effects shown both in shoot (12.83 ± 0.5 cm) and root (5.37 ± 0.5 cm). Maximum confirmations were fixed with the help of MgO NPs characterization through TEM, SEM, FTIR, zeta potential, and X-ray. The effect of MgO NPs showed a significant increase in root and shoot length, and simultaneous in-vivo studies also showed significant results in plant physiological parameters. In effect, the vital performance in germination rate, potential, and index MgO NPs was higher than the control. Moreover, the performance and absorption of MgO NPs was confirmed by physiological characterization with the help of a UV–Vis spectrophotometer applied to the leaves and roots. It was demonstrated that the influence of MgO NPs is positive and potentially can be used for seedling growth and also for plants. It may bolster farming methods, and help maintain high food quality, quantity, and production.
