Effect of Adding Banana Peel Biochar on the Growth of Vignaradiata in Heavy Metal Contaminated Soil

Rohit Kalale | Serene Hepzibha

Abstract: We investigated the potential application of banana peel biochar (BPB) for the adsorption of heavy metals (Ba, Cd, Cu, Pb) in contaminated soil. The study proved that banana peel biochar is effective in neutralizing lead and copper toxicity in contaminated soil. The percentage increase in height with BPB was Copper (28.56%) > Lead (15.51%) > No Chemical (13.70%) > Barium (5.24%) > Cadmium (3.87%). This study revealed that when copper and lead - treated V. radiata plants are supplemented with banana peel biochar, they show better growth, yield and survival percentage as compared to untreated, metal ion - contaminated plants. Therefore, banana peel biochar can serve as an eco - friendly, low - cost, and efficient adsorbent to immobilize heavy metals in contaminated soils.
