Abstract:
A pot experiment was conducted at the Agronomy research field, Sher-e-Bangla
Agricultural University, Dhaka from November 2018 to February 2019, to mollify the
toxic effect of Cd on potato

soil. The result
revealed that all growth and yield contributing parameters positively responded with
increasing MSE levels except days to emergence and days to maturity. Quality
parameters like tuber peel and flesh also increased gradually with the increasing levels
of this treatment. The effect of Si levels were also significant on growth, yield and
quality contributing parameters viz., quality of potato peel and flesh, dry matter
content, specific gravity of tuber were increased gradually. Yield of potato increased
with increasing Si levels. Cd content of potato tuber flesh and peel gradually
decreased with increasing both MSE and Si levels. M
