Abstract

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 (E_0?.E₁₀₀) each having three replicates were made. E₀ was taken as control in which tap water was used for irrigation of the plants. For E_20, E_40, E_60, 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.
