Abstract EN

A biological experiment has been carried out in the Department of Soil and Water Resources the College of Agriculture-AL-Qasim Green University in summer season (2014) in order to identify the effect of adding different levels of soild sewage sludge (sludge) and Pb and the interaction between them in the pepper plant (Capsicum annuum L.) in two different texture soils clay soil (s1) and sand soil (s2) , a biological experiment involved cultivation in plastic pots included three levels of lead in from of nitrate phase (0 , 234 , 468) mg.kg-1 respectively, and four levels of sludge (0 , 30 , 60 , 90) gm.kg-1 and two soils (clay s1 and sandy s2) and the cultivation of pepper plant (Capsicum annuum L.) , The design CRD was used in the stady, included three levels of pb and four levels of sludge two different texture soils with five replicates bringing the number of experimental units to be (120) unit , results showed: That significant increase when adding the sludge with level (90) gm.kg-1 in the overall total and available concentrations of lead in soils of case-study and the presence of a significant increase when adding the sludge with level (90) gm.kg-1 to contaminated soil with lead in the concentration of total and available element (234, 468) mg.kg-1 .And for the total concentration of element which absorbed by plant the results showed that the highest of lead accumulation in plant was when adding levels (90) gm.kg-1 of heavy element (sludge).
