Effect of biochar and various levels of NaHS on the enzymatic antioxidants activity of maize grown under drought stress. MDS = moderate drought stress; SDS = severe drought stress; To = control, T1 = 3% biochar mixed with pot soil, T2 = 0.05 mmol L− 1 NaHS application, T3 = 0.1 mmol L− 1 NaHS application, T4 = biochar mixed with pot soil + 0.05 mmol L− 1 NaHS application and T5 = biochar mixed with pot soil + 0.1 mmol L− 1 NaHS application.
