Abstract

This paper evaluates the physico-chemical properties of effluents of Kisan Sahkari Chini Mills Limited Satha, Aligarh (UP) India (KSCML) and Panniji Sugar and General Mills, Bulandshahr (UP) India (PSGM), and the effects of PSGM effluent on soil and crop plants. The effluents were high in various solids, COD, BOD, chlorides, sulphates, and had low dissolved oxygen and moderately alkaline pH. The effluents disturbed the pH, N, P, CaCO 3 and organic matter, the greatest perturbance being observed in the potassium of the soil when effluent was used for irrigation. The effluent was applied to kidney bean Phaseolus aureus and millet Pennisetum typhoides seeds in four concentrations (100%, 75%, 50% and 25%). Germination in the water-irrigated soil was 100% whereas it ranged between 99% and 91% in other concentrations of the effluent. The water-irrigated soil and the soil irrigated with 25% effluent were found most suitable for germination. It is suggested that the sugar factory effluents be used for irrigation after dilution.
