Any cadmium (Cd) contaminated soil might cause reduction in plants’ yield and increase the hazard of Cd-contaminated plants consumption by both human and animals. The research aimed to investigate the effect of EDTA chelate on Cd uptake in pot marigold (Calendula officinalis L.). A factorial experiment using randomized complete blocks was used in three replications. Treatments included application of 0(C0), 25(C25), and 50(C50) Mg ha-1 cow manure in a Cd polluted soil [ 0(Cd0), 5(Cd5), and 10 (Cd10) mg Cd kg -1 soil] and two rates of EDTA chelate (0 and 2.5 mmol kg-1 soil). Applying 2.5 mmol EDTA chelate caused significant increase in shoot Cd uptake by 21% and 25% in a Cd polluted soil (10 mg Cd kg -1 soil) treated with 25 and 50 Mg ha-1 cow manure, respectively. Also, addition of 2.5 mmol EDTA chelate caused an increase in the root and shoot bio-concentration factor. The results of this experiment showed that applying 2.5 mmol EDTA would increase the Cd availability, which could be considered as a factor that plays an important role in Cd remediation in soils treated with organic amendments.
