This study presents the remedial ability of maize on lead(Pb)contaminated *** samples were collected randomly from the site and subjected to physico-chemical tests before *** samples were contaminated artificially at six different concentration levels of lead nitrate(Pb(NO_(3))_(2)).Experimental design was 4-factorial combination(6×6×2×1).The study duration was 10 weeks,and during this period,Pb contents of the soil were analyzed in intervals of two *** physico-chemical properties of the soil showed that the soil was loamy with pH 6.82,electrical conductivity 1.62 dS/m and adequate macro nutrient *** av-erage percentage removal of Pb from the soil was 2.25%and 3.67%for potted and non-potted experiments,***,the average percentage of Pb in the roots was 1.10%and 1.68%for potted and non-potted experiments,*** result of this study indicated that extraction of Pb by the plant system increased with the increase of lead concentration in the soil as well as in the extent of vegetation attained by the *** also clearly showed that the non-potted experiments demonstrated greater influence on removal of Pb from the soil system than the potted experiments.
