Abstract
The present paper deals with the physico-chemical characteristics of Doon Distillery, Doiwala effluent and its in-vitro effect on seed germination of four agricultural crops i.e. Solanum melongena (Brinjal), Cicer arientinum (Black gram), Glycine max (Soyabean) and Lycopersicon esculentum (Tomato). The physico-chemical characteristics showed high degree of pollution load in the effuent as it is evident by high degree of BOD (35375mg/l), COD (81000 mg/l), MPN/100 ml (30.56x105) and SPC (72.33x106). The effect of effluent treatment on seed germination in-vitro showed a significant negative co-relation between different concentration of the effluent (5 to 100%) and in percentage of seed gemination of S.melongena, C. arietinum, G.max & L. esculentum. In all these four crops maximum percentage of seed germination was observed at 5% concentration of effluent. Germination of seeds treated with different doses was only recorded up to 25% concentration. Effluent showed deleterious effect at 50% and above that no seed germination was found.
