Abstract :
The impact of applied farm manure (FM) on growth of maize and tissue Pb concentration in maize grown on saline-sodic sandy loam and sandy clayey loam textured Pb-toxic soils was evaluated in present pot study. The soils were spiked with Pb at 200 kg ha-1soil and equilibrated for 60 days at about field capacity. Treatments were comprised of three levels of FM (0, 20 or 40 g kg-1soil) arranged in completely randomized design each replicated thrice. The highest dry matter of maize shoots from sandy loam soil was recorded with the applied 40 g kg-1FM. From sandy loam soil, maximum dry matter of shoots was noted with FM at 20 and 40 g kg-1. Applied FM at 20 and 40 g kg-1produced statically similar dry matter of maize roots in sandy clayey loam soil. While in sandy loam soil, 20 g kg-1FM application resulted in significantly (p ≤ 0.05) higher dry matter of maize roots than control treatment and 40 g kg-1FM application. The applied FM at 20 and 40 g kg-1 consequence in statically similar shoot and root Pb concentration grown on both textured Pb-toxic soils but lower compared to that of the control soils. For post-experiment soils, minimum plant available Pb in sandy loam soil with FM at 40 g kg-1was recorded while in sandy clayey loam, minimum plant available Pb was observed with the addition of FM at 20 and 40 g kg-1.
