dc.description.abstractA study was conducted to isolate the efficient microorganisms to hasten the process of silkworm pupal residue degradation and evaluation of silkworm pupal residue compost on growth and yield of french bean and tomato. Among the twelve microbial cultures screened during silkworm pupal degradation, four efficient cultures were selected to prepare the consortium based on their ability to produce enzymes, carbon and nitrogen mineralization efficiency which included two fungi (Aspergillus aculeatus and Penicillium simplicissimum), one bacterium (Bacillus licheniformis) and one actinobacterium (Streptomyces noursei). Composting was carried out by mixing agricultural wastes with silkworm pupal residue in 1:2 ratio treating microbial consortium. Composting using silkworm pupal residue waste with silkworm litter and vermicompost was an ideal substrate combination. The lowest C:N ratio of 10.09 was recorded in the treatment T3 (T2+silkworm litter) with highest per cent N (2.82%). Highest dehydrogenase (198.1 μg TPF g-1 hr-1) and urease activity (448.3 μg NH4+- N g-1hr-1) was observed in the treatment T3 (T2+silkworm litter), whereas maximum acid and alkaline phosphatase activity was recorded in the treatment T7 (T2+vermicompost) and T3 (T2+ silkworm litter) (160.6 and 185.67 μg PNP g-1hr-1 respectively). Application of compost prepared with silkworm pupal residue waste with silkworm litter and vermicompost to french bean and tomato resulted in higher plant growth and yield which was on par with the plants received recommended dose of fertilizer with bio-fertiliizer. Application of compost prepared with silkworm pupal residue waste in combination with silkworm litter and vermicompost enhanced the chemical and biological properties of soil compared to the soil which received inorganic fertilizersen_US
