FIGURE 1

Effect of combined application of TU and BC on (A) shoot fresh weight, (B) shoot dry weight, (C) leaf area, and (D) shoot length grown under cadmium (Cd) contamination. Values are averages ± SD (n = 3). Different statistical letters represent significant differences in values between treatments (using Tukey’s multiple range test, p < 0.05). TU, thiourea; BC, biochar; T0 = 0 mg L–1 thiourea; T1 = 600 mg L–1 thiourea; T2 = 600 mg L–1 thiourea; B0 = 0% w/w BC; B1 = 2.5% w/w BC; B2 = 5.0% w/w BC.
