Description The present investigation entitled “Studies on Composting of Kitchen Waste through Microbial Decomposers and their effect on Plant Growth Promotion and Biotic Stress Management of Crops” was carried out in the Department of Plant Pathology, College of Agriculture, IGKV, Raipur (C.G.). Total seventeen isolates (eleven fungal isolates and six bacterial strains) were isolated from decomposed kitchen waste procured from residential area of Professor Colony, Krishak Nagar Jora, Raipur (C.G.). Among these only four fungal isolates (F4, F5, F8 and F10) and one bacterial strain (8B) were found to be potential based on their rate of decomposition. In which, isolates F4, F5, F8 were identified as Trichoderma viride, F10 was identified as T. harzianum and bacterial strain 8B was identified as Pseudomonas sp. These five isolates of microbial decomposers and T. viride (TV) isolate of Biocontrol Lab, IGKV, Raipur (CG) were used for further study. For decomposition of vegetable waste, addition of 20% water content and 5 ml of inoculum suspension was recorded best.
Among the solanaceous (S), cruciferous (CF), cucurbitaceous (CB) vegetables, fruits (F) and kitchen waste (KW), cruciferous vegetables (CF) were fast degraded by isolate F4 (T. viride) within 5 days in comparison to other isolates. Seed treated in decomposed extracts collected from solanaceous, cruciferous, cucurbitaceous vegetables, fruits and kitchen waste by microbial decomposers, cucurbitaceous decomposed extracts by F4 and F5 (T. viride) were found best for seed germination and seedling growth of cowpea in comparison to other isolates. All decomposed extracts showed non phytotoxic to cowpea plant. Seed treated for thirty minutes in decomposed extracts of kitchen waste for growth of cowpea was found best. Kitchen waste compost prepared by different isolates of microbial decomposers showed non phytotoxic effect on crops. Kitchen waste compost (KWC) prepared by 8B (Pseudomonas sp) was found best than other microbial composers on plant growth promotion (PGP) of crops. No mortality was recorded by kitchen waste compost prepared by F5 and F8 (T. viride) which was incorporated in rows of crops while minimum mortality was recorded in KWC prepared by 8B incorporated rows of crops.
