Influence of seed priming with different concentrations of nZVI on yield-related traits; a percentage of hollow grains, b grain density, c seed weight per 100 seeds, d.Yield (kg m⁻²). Data represent the mean of five replicates and error bars represent standard error. Means with the same letters are not significantly different (Tukey’s HSD multiple comparisons at p ≤ 0.05). Significant differences between session 2018 and 2019 plants are indicated by symbol ‘*’ as obtained from unpaired t test analysis
