Cadmium (Cd) is a heavy metal that neutrally occurs in soil. It carcinogenic humans and caused significant decline the plant's growth when up has taken beyond threshold limit. The fertilizers, manure, sewage sludge, aerial deposition are main source of cadmium contamination Furthermore, poor soil organic matter also one allied factors which facilitate development Cd toxicity decomposition resistance nature biochar makes it an effective amendment for remediation. Through crop production, enters food system. Individual studies on compost found literature but combined effect rarely documented especially maize crops. current pot study was conducted Pesticide Quality Control Laboratory, Multan, Pakistan. However, novel by using mixed (CB) against maize. Four application rates CB i.e., 0, 0.50, 0.75 1.00% (1.00CB) were applied under 3 levels 0 (0Cd), 2.5 (2.5Cd) 5 mg kg−1 (5.0Cd). Overall, results indicated 1.00%CB remained significantly best at higher 5.0Cd improvement matter, plant height, root length, number leaves, leaves fresh dry weight, chlorophyll a, b, total carotenoids. A decrease pHs, anthocyanin lycopene validated efficacious functioning over control 5.0Cd. In conclusion, use better approach to harmful effects improve gas exchange attributes, contents Long-term research required co-composted toward mitigation different geographical locations.
