“…Regarding root length (RL) (Figure 1C), the highest value obtained was 35.1 cm with the PaB ratio of 38%. Vasconcelos et al (2018) observed the effects of PaB on the substrate when compared to other materials, such as açaí wood, sawdust powder, and black soil. The authors observed that the plants grown in the substrate composed of PaB obtained better results, reaching 8.36 cm of root length.…”
