The study has been focused on effect of untreated distillery effluent (Devans Breweries Ltd., Jammu) on germination of gobi sarson (Brassica napus. L. var. Punjabi Special). Six treatments (E0....E100) each having three replicates were made. E0 was taken as control in which tap water was used for irrigation of the plants. For E20, E40, E60, E80 and E100, different concentrations i.e. 20, 40, 60, 80 and 100% of effluent were used for irrigation, respectively. The 100% sample of distillery effluent analyzed for various physicochemical parameters showed acidic nature (pH 4.0) and higher values of COD (2496 mg l-1), TDS (799.7 mg l-1) and chlorides (1408 mg l-1). The parameters e.g. percent germination, germination index, speed of germination, and peak value were highest in treatment receiving 20% effluent concentration which also showed minimum values for percent inhibition, germination period, and delay index.
