The effect of different levels of biomethanated distillery spentwash and pressmud biocompost application on soil microbial and enzymatic activity was examined through a field experiment. The field experiment was conducted using Groundnut (Arachis hypogaea L.) as a test crop at farms of M/S. Bhavani distilleries and chemicals Ltd., T.Pudur, Thimiri, Vellore District. The results of the study showed that the microbial population and enzymatic activities of the soil were substantially increased throughout the crop growth period due to spentwash and bio-compost application. The highestmicrobial population and enzyme activitieswere recorded with presown application of BDS at the rate of 100 m3ha-1 alongwith RDF-NP. The utilization of spentwash at an optimumlevel of 100 m3ha-1 soilwill increase the activities of soil microbes and enzymes thus enhancing the fertility status besides paving an eco-friendly approach for the disposal of the spentwash.
