Impact of Textile Dyeing Effluents on Germination and Seedlings of Country Beans (Lablab niger var. typicus)

Abstract

An experiment has been completed on the impact of dying effluents on germination and
seedlings of country beans (Lablab niger var. typicus Medikus, Fabaceae). Seven types of
dyeing effluents have been taken as treatment variables, and their effects on the germination of
country beans at the early growth stage compared The treatment of neutralized effluent water
(D5) enhanced the germination percentage remarkably (100%) as well as statistically identical
with the result of underground water (D1) whereas the treatments of effluent from 2nd wash
after Bath (D4) and mixed effluent from ETP showed poor germination (73.33%). Second wash
after scouring and bleaching treatment (D2) showed a good result. All results have been
considered on the basis of germination energy, relative germination rate, effluents injury rate
and germination velocity. Neutralized effluent water (D5) performed better at the seedling
growth period of country bean plants. But D4 treatment performed very poorly among all
parameters. So, it can be suggested that, neutralized effluent water should be applied as
irrigation water for the purpose of crop production as well as country bean cultivation and a
sustainable environment.
