The physico-chemical characteristics of distillery effluent was toxic as it contained high values of EC, TDS, TS, cations, sulphate, sodium, potassium, calcium, magnesium and nitrate. A high value of BOD and COD was noted and it is devoid of DO. The impact of distillery effluent on the morphometric, biochemical and enzymatic characteristics of the vegetable crop was analyzed after 90 days. The reduction in all the growth characteristics and biomass accumulation was parallel with reduction in carbohydrate and pigment content. The protein content and nitrate reductase also decreased with increasing concentration of distillery effluent. An increased leaf nitrate, free amino acids, L-proline, peroxidase and catalase indicated the stress nature of the plant. Applications of low cost environment friendly bioadsorbent (Azolla) ameliorate the stress caused due to toxicity of distillery effluent. A significant increase in germination percentage, growth, biochemical and enzymatic characteristics was noted in the bioadsorbent treated experimental plant than when they were treated with various concentration of distillery effluent alone.
