Effect compost and biochar on the total anthocyanin (TAC) and total flavonol (TF). BIC1 and BIC2 = biochar at rates of 1 and 2% (w/w), COM1 and COM2 = compost at rates of 1 and 2% (w/w), and BIC1 + COM1 = mixture of the two amendments at 1% (w/w) of each. Means (± SD, n = 5) denoted by the same letter indicate no significant difference according to Tukey’s multiple range tests at p < 0.05.
