A pot experiment was laid out to investigate the impact of different levels of Lead and FYM on phosphorus uptake by plant components and total phosphorus uptake by the crop in texturally different soil. Treatments were comprised of five level of Pb (0, 5, 10 20 and 40 ppm) applied as Pb (NO3)2 and two levels of FYM (0 and 10 t ha-1) applied on two texturally different soils (Loamy sand and Clayey soils). The Result revealed that phosphorus uptake by plant components and total P uptake was significantly decreased with increased Pb levels (0 to 40 ppm). This might be due to with increasing dose of Pb reducing the uptake of phosphorus through raising the level of toxicity. When organic matter with reactive groups such as hydroxyl, phenoxy and carboxyl effectively controls the adsorption and complexation of Pb and the activity of Pb in the soil, the application of FYM @ 10 t ha-1 gave significantly higher uptake of phosphorus as compared to no FYM explicated plot. In addition, applied FYM has not increased the removal of P by plant along with increasing doses of Pb but its reduced the toxicity of this metal meanwhile reducing trend of P uptake with increasing doses of Pb was same as no FYM treated plot.
