ABSTRACT
The study was conducted to estimate the characteristics food industrial effluents, well and canal water for irrigation and to assess the possible impacts on soil and crop during the year of 2011-12 . Mixture of treated and untreated effluents of namkin, milk and rasgulla industries, water quality class comes under C2S1 to C3S1 which is moderately high salinity to low sodium hazards. The RSC of the effluent except milk industry and lake effluent was higher in range i.e. 2.63 to 3.54 indicating unsuitable for irrigation, due to as it may develop sodicity in soil by its continuous use. The RSC of milk industry, canal , lake and well water was observed in the range of 1.11 to 2.31 me L-1 , which comes under marginally suitable class for irrigation. The micronutrients (Fe, Mn, Cu and Zn) in effluent was within the permissible limit of NEQS. Soils receiving effluent irrigation and crops grown were containing higher proportion of micronutrients as compared to soils and crops receiving well water and canal water irrigation. The soils receiving mixed industrial effluent irrigation were found rich in available N, P, K and organic carbon as compared to soils receiving well water and canal water irrigation.
