Physico-Chemical Analysis of Sugar Industry Effluent and Its Effect on Seed Germination of Vigna angularis, Vigna cylindrical and Sorghum cernum

Abstract

We assessed physico-chemical parameters of treated waste water effluents from a sugar industry and determined the effect of various concentrations (0%, 20%, 40%, 60%, 80 % and 100%) of effluent on seed germination, germination speed, peak value and the germination value of mung ( Vigna angularis ), chavali ( Vigna cylindrical ) and jowar ( Sorghum cernum ) seeds. The low effluent pH (4.35), total dissolved solids, (TDS, 720 mg/L) and chemical oxygen demand, (COD, 1330 mg/L) indicate the high inorganic and organic content with an acidic load. Germination percentages and germination values decrease with increasing concentration of effluent in all the seeds tested. Permanent URL: http://hdl.handle.net/2047/d20000978
