Physico-chemical Analysis of Sugar Mill effluents and their effects on Leguminous Plant growing in North Bihar

In India, North Bihar is primarily known for agricultural activities. It is specially recognized as sugarcane growing area that led to the growth of large number of sugar mills. Narkatiaganj sugar mill is one of them. It is discharging effluents in open drains through which it is directly connected to rivers. The adjoining areas of the factory are famous for their Pea (PisumsativumL.) growing region. This led to the selection of pea plant as atest species of this research project. Two well-known varieties of PisumsativumL. named asArkel and Azad-1 were selected to study the effect of effluents discharging from sugar mill. Physico-chemical analysis of sugar mill effluent, collected from Narkatiaganj were analyzed to ascertain the composition, particularly with reference to pH, Temperature, Conductivity, Turbidity, DO, BOD, COD, Phosphate, Total Solids, Nitrogen, Alkalinity, Free CO‚ and Potassium.All the parameters were observed to be higher than the usual limit. The effect of the effluents on the PisumsativumL. was studied for their germination, growth and reproductive behavior of the plant. It was marked that sugar mill effluents are very much responsible for low productivity of Pisumsativum L.
