Shoot height (A, B) and root length (C, D) of four holy basil varieties from three companies; G-NT, G-TS, R-JT and R-TS treated with difference light treatments under 0% and 0.4% KNO3 concentrations at 15 days after sowing. Different letters above bars indicate significant differences among light treatments on the same brand at P < 0.05. “ns” indicates no significant difference. Data are mean values (n = 4) ± SE.
