Comparison of foxtail millet quantitative, nutritional, and physiological parameters in the zinc oxide nanoparticles (ZnO NPs) foliarly applied variant and the control when harvested after 95 days. This included the standard deviation (±SD) and calculation by Fisher’s least significant difference (LSD) test.
