This study was investigated to evaluate the effect of humic acid on cadmium uptake in Gazania rigens at the Islamic Azad University, Science and Research Branch. The experiment was carried out in a completely randomized design (CRD) with 2 factors humic acid at 2 levels (100,200) and cadmium at 2 levels (3 and 5 mg/L) in three replications. Several traits such as Uptake of Pb and Cd roots and stems, proline, anthocyanins, chlorophyll was measured. The results showed that 200 mg/L Humic acid had a significant difference compared to the control. Increasing humic acid improves biochemical parameters such as proline, chlorophyll.
