Randomized trial examines how manganese oxide nanoparticles improve maize growth under salt stress, suggesting practical agricultural applications.

This research investigates the effects of manganese oxide nanoparticles on maize growth under saline conditions.
Plants of Zea mays were grown in half strength Hoagland solution with salinity levels of 0, 100, and 150 mM NaCl.
The experimental design was completely randomized with 6 replicates per treatment.
Characterization of manganese oxide nanoparticles was performed using FTIR, X-ray diffraction, SEM, and UV-Vis Spectrophotometry.
Application of Mn2O3-NPs resulted in improved fresh and dry biomass at 100 mM NaCl.
Under Mn2O3-NPs treatment, leaf Na+ levels decreased while K+ levels increased, indicating enhanced nutrient balance.
Antioxidant markers and secondary metabolites showed increased levels in saline treatments but decreased in Mn2O3-NPs treated plants, demonstrating efficient ROS scavenging.
