Abstract
An experiment was conducted on the impact of dying effluents on germination and seedling stage for the production of country bean (Lablab niger var. typicus). Seven stages of Dyeing effluents were used as treatment variables and compare their effect on germination attributes and early growth stage of country bean. The treatment of neutralization stage ( D5) to 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) & mixed effluent from ETP were showed poor germination (73.33 %) . Second wash after scouring and bleaching treatment (D2) also showed good result. All results has been taken by considering other germination oriented parameters, such as germination energy, relative germination rate, effluent injury rate and germination velocity. On the contrary, outstanding result was showed at seedling growth stage from the treatment of D5 except others. But D4 treatment performed very poor among all parameters. So, it can be suggested that, D5 stage of textile effluent might be applied as irrigation water for the purpose of crop production as well as country bean cultivation and sustainable environment.
