Time efficient co-composting of distillery and paint sludge industrial wastes with 2:1:1 ratio of water hyacinth, cow-dung and saw-dust in combination with Trichoderma viride, Phanerochaete chrysosporium, Bacillus cereus and earthworms was done. The decrease in MC, TOC and C:N ratio and increase in temperature, TKN, pH, TK, TP was significant. Out of five treatments, DS3 (60% distillery sludge) and DS4 (80% distillery sludge) treatments were stable and matured with C:N ratio of 18.68 ± 1.1 and 14.73 ± 1.12 respectively. Maximum earthworm numbers (26) were obtained in DS1 substrate and maximum cocoons (10) were counted in PS1 substrate. 20% (w/w) vermicompost mixed soil induced the growth in root length (4.6 ± 0.21), shoot length (5.4 ± 0.10) and 90% GI while >20% (w/w) have inhibitory effects on plant growth. Therefore these treatments can be applied in agronomic field as a soil amendment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
