摘要：A field experiment was conducted with different irrigation doses of distillery spent wash along with inorganicN and P fertilizer without K using maize variety COH (M)-5 as test crop and groundnut as residual crop. Inorder to assess the quality of groundwater due to distillery spent wash application, piezometers of 1 m depthwere installed in five treatments viz., 25, 50, 75,100 kL/ha and in the control. Piezometer water samples werecollected at regular intervals and analysed for various water quality parameters. The leachate study withpiezometer of 1m depth indicated that the pH, EC, cations, anions, BOD, TDS, SAR and RSC of theleachate were slightly increased in distillery spent wash applied treatments, compared to control. However,in the leachate collected after fourth and fifth leachings, the levels of cations, anions, BOD, TDS, SAR andRSC were decreased.
