Remediation of phytotoxic effect of chromium by different amendments in berseem crop grown in sewage and tubewell water irrigated soils

Abstract

A screen house experiment was carried out to study the direct effect of chromium(Cr) application in the presence and absence of amendments in berseem crop grown on sewage and tube well water irrigated soils with three replications under factorial completely randomized block design. The results indicated that berseem dry matter yield (DMY) decreased significantly due to direct effect of Cr application but the presence of amendments increased the dry matter yield up to 80 mg/Kg of applied Cr. No harvestable yield was obtained at higher levels of chromium application. The chromium content and chromium uptake also increased significantly with increase in levels of applied chromium. The application of amendments decreased the chromium content and uptake. The toxic effect of Cr on crop could be mitigated more effectively with FYM application than lime and reduce risk of health hazards for human beings and animals.
