MOLLIFICATION OF CADMIUM TOXICITY IN POTATO TUBER GROWING IN TREATED SOIL BY USING MORINGA SEED EXTRACT AND SILICON

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 : Control soil, M 2 : 6% solution in 50 ml water kg -1 -1 soil soil and M soil; Factor B :Levels of Si as Sodium Silicate x 1 : 3% solution in 50 ml water kg 3 : 9% solution in 50 ml water kg 0 : Control soil 1 : 100 mg kg -1 soil, Si 2 : 200 mg kg -1 soil and Si 3 : 300 mg kg -1 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
