Abstract: This study was conducted in the greenhouse of Biology Department in the College of Science-University of Salahaddin- Erbil. In this study, the interaction effects of exogenous Silicon (Si) and Pb on peas plant were researched. This experiment consisted of combination treatments of foliar spray with different Silicon(Si) concentrations at doses (0,100, 200, 300ppm) and soil irrigation by two lead (Pb) concentrations (0, 100 mg.Kg-1 soil). The following growth parameters were observed; plant height, number of leaves, number of branches, dry weight of shoot system, water content, and yield characteristics including number of pods per plant, number of seeds per pod, dry weight of 100 seeds and chlorophyll content. The results elucidate that Si significantly decreases the negative effect of Pb on plant height, dry weight of 100 seeds, chlorophyll b and total chlorophyll content.
