FIGURE 2.
Impact of compost, biochar, and co-composted biochar on physiological parameters of Brassica. (A) Photosynthetic rate, (B) transpiration rate, (C) stomatal conductance, (D) chlorophyll content, (E) relative water content, and (F) electrolyte leakage. The values are presented as mean ± standard error (n = 3). The values sharing the same letter(s) in bars are statistically non-significant with each other at p < 0.05.
