Abstract
Artificial contamination with lead nitrate (Pb(NO3)2) for three doses of Lead- 10, 20 & 50 ppm was given to soil. The results showed that maximum concentration of Pb was 6.49 ug/g in 60 DAS root in LS (late sowing) at 50 ppm and minimum concentration of Lead was 0.05ug/g in control in timely sowing (TS) in 60 DAS root. EDTA showed less effect at younger stage of plants (40 DAS) and was reported more effective in leaf (5.73 ug/g) at 20 ppm in 60 DAS in LS.
