Role of sole and combined application of BR and BC on photosynthetic pigments contents of wheat under 35 WHC and 75 WHC. Bars show means of three replicates. Different error bars represent SE. Different letters indicate significant difference at p ≤ 0.05; LSD Test (75 WHC well-watered, 35 WHC drought stress, C control, BR1 1 μmol foliar applied 24-epibrassinolide, BR2 3 μmol foliar applied 24-epibrassinolide, BC timber waste biochar).
