Abstract: The biological experiment was conducted from 25/11/2015 to 11/5/2016 in the experimental farm of the Agriculture College, University of Salahaddin at the Grdarasha field 3.5 km, south of Arbil governorate, 36 ̊ 07 N, 44 ̊ 01E, 0411359, 03997002 UTM. 411m above the sea level, during growing season 2015-2016 in order to determine the effect of triple super phosphate in different levels of phosphorus (0, 20, 40,60 and 80 mg kg^-1) on heavy metals concentration in plant and uptakes of faba bean plant (Vicia faba). Soil samples were collected under the polluted location in the landfills which were located between Bnaslawa district and Daratoo county, using factorial complete randomize design with three replicates. The increase of applied P caused a significant increase (p ≤ 0.05) of the dry matter weight of plant and caused a significant decrease of heavy metal concentration. A negative correlation coefficient between P and Fe, Zn and Pb concentrations in pods of field bean were (- 0.93, – 0.97 and – 0.92) respectively.
