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-1
soil and
equilibrated for 60 days at about field capacity. Treatments were comprised of three levels of
FM (0, 20 or 40 g kg-1
soil) 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-1 FM. 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-1 produced statically similar dry matter of maize roots
in sandy clayey loam soil. While in sandy loam soil, 20 g kg-1 FM application resulted in
significantly (p ≤ 0.05) higher dry matter of maize roots than control treatment and 40 g kg-1
FM 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-1 was recorded while in sandy clayey loam, minimum plant available Pb
was observed with the addition of FM at 20 and 40 g kg-1
.
