Abstract

The use of sewage sludge in agriculture is an alternative strategy to reduce waste production. The goal ofthis study was to evaluate the impact of sewage sludge (SS) from various sewage treatment plants (STPs)on seed germination, growth metrics, and chlorophyll content in Vigna radiata L. var. Samrat. The experimentwas first carried out under controlled conditions, then in the Zaid season at the nursery of forestryDepartment, SHUATS, Prayagraj, a field experiment with seven treatments and three replications wasconducted. Sludge’s initial physico-chemical examination had revealed greater EC, lower pH, and moremacro- and micronutrients as well as heavy metals over control. According to the results of the controlledexperiment, there was less seed germination, shoot length, and seedling vigour index compared to thecontrol. At lower concentrations, data in a field trial indicated good results, but at 45 and 60 days aftersowing, substantial reductions in several growth metrics and chlorophyll content were seen at greaterconcentrations with various sludge applications as compared to the control.
