Use of phytoremidation technique in reclamation of soils contaminated with some heavy metals (C0, Cu, Pb) by cultivating Canna generalis plant

A pot experiment was carried out in the wooden canopy of Musayyib Technical College / Department of Soil and Water Techniques located in Musayyib project using soil with a loam texture brought from Musayyib project field from surface layer (0-30 cm), to study the bioremediation of soil contaminated with some heavy metals (Co,Cu,Pb) using Canna  generalis plant, to evaluate efficiency of this plant in bioremediation process of contaminated soil , accumulation of Lead, Copper and Cobalt in soil accordance with international standards for soil pollution. Young Canna  generalis plant  seedlings (one week old) were planted at a rate of two plants in 25 kg  plastic pots in winter on 14/11/2021  for a period of three months, they were then reduced to one plant. Factorial experiment was carried out according to a complete randomized  design (CRD) using Canna  generalis plant, five different levels of heavy metals (CO, Cu, Pb) and three replications, bringing number of experimental units to 45 experimental units .Tretments are To, T1, T2, T3, and T4, including adding elements CO, Cu, and Pb separately at levels 0.0, 10, 20, 40, 60 mg kg-1
