Relative water content (a), proline content (b) and seed yield (c) in soybean affected by water status and zinc concentrations. Zn concentrations 0-200 mg Zn/L are for ZnO-NPs, and 400 mg Zn/L is for ZnSO4 used for comparison as conventional fertilizer. Bars with similar letter are not significantly different, according to Tukey’s post hoc test (p < 0.05). Error bars represent ± SD.
