Sugar Mill Effluent Toxicity In Crop Plants

The laboratory experiments were conducted to know the effect of different concentrations of sugar mill effluent on seed germination, biochemical content of crops. The experiment was conducted with the both crops at different concentrations of sugar mill effluent. The growth parameters such as germination percentage, seedling length, lateral roots, dry weight, were measured at 7 th DAS. After sowing (DAS) the pigment content viz., chlorophyll a, chlorophyll b, total chlorophyll, carotene, sugar, starch, amino acid, protein contents were analysed at       7 th day. All morphological growth parameters, biochemical contents, were found to increase at 5% effluent concentration and it decreased from 10% effluent concentration onwards. So these results reflect   that the sugar mill effluent is toxic to crop and it can be used for irrigation purpose after a proper treatment with appropriate dilution.
