Abstract :

This study was undertaken to evaluate the effect of sugar industry effluent on locally cultivated variety of green gram LGG 460. The physicochemical parameters like pH, TDS(510mg/l), BOD(550mg/l), COD(680mg/l), EC(1.056), chloride(162mg/l), sulphate(12) were analysed. The chemical parameters indicate that there is high organic and inorganic content, high amount of suspended solids and acidic load. Regular use of this effluent adversely affect the soil and crop yield. A study was conducted to know the effects of different concentrations ( 20, 40, 60, 80, 100) of sugar industry effluent on seed germination of green gram LGG 460. The study reveals that the germination efficiency is reduced due to low pH 6.5 and other chemical parameters of effluent water. In low concentrations the seeds thrive better and at high concentrations the seeds are affected. Germination rate decreased with increasing concentration of effluent.
