An experiment was conducted at the college of sericulture, chintamani, chickkaballapur district, karnataka, india. the insect species used for the enrichment of composting in the experiment are silkworm pupae, silkworm moth, uzifly and fruit fly, the compost was prepared for 90 days and used to study their influence on post-harvest soil of finger millet. In the field experiment conducted, with 11 treatments which are replicated thrice, all the treatments with enriched insect biomass compost performed well. In the field experiment the higher test weight (3.04) was noticed in treatment T4 (100 % N equivalent of FYM through silkworm pupae compost) and the higher grain and straw yield (28.91 q ha-1 and 38.01 q ha-1) was observed in T4 treatment. In finger millet grain and straw, nitrogen, phosphorous, potassium, calcium, magnesium, and iron content varied significantly due to different treatments. Significantly higher concentrations were found due to 100 % N equivalent FYM through silkworm pupae compost (T4) followed by T6 which received 100 % N equivalent of FYM through silkworm moth compost. Higher B: C ratio of 2.42 was recorded in T4 (100 % N equivalent of FYM through silkworm pupae enriched compost) followed by T6 (2.40), T10 (2.26) and T8 (1.95). Lower B: C ratio of 1.29 was obtained in the absolute control.
