Bg = biochar grass; Bc = biochar chat; If = inorganic fertilizer; Wfb =  control plot (free from biochar and fertilizer); PHI = plant height at the initial stage; PHII = plant height at mid-stage; PHIII = plant height at the development stage; PHIV = plant height at a late stage. Treatments with the same letters were not significantly different at .
