EFFECT OF RAW AND TREATED PAPER MILL EFFLUENT IRRIGATION ON VIGOUR INDICES OF CERTAIN CROP PLANTS

Abstract

                                Irrigation with the combined raw effluent from paper and pulp mill reduced the germination and vigour indices of crop plants. The combined effluents after dilution did not significantly affect the germination and growth. The combined effluent after aerobic treatment in a benchscale activated sludge system, when used for irrigation without any dilution favoured the growth of crop plants.

Key words : Effluent irrigation, Paper mill effluent, vigour indices.
