The results revealed that a highly significant difference in C: N ratio between the treatment groups and between different stages of decomposition. The C: N ratio is the indicator of the level of decomposition of the manure. The decomposition process is considered complete when the C: N ratio < 20:1. The required C: N ratio was achieved at a significantly shorter duration (60 days) in treatment 1, followed by treatment 2 (75 days), treatment 3 (90 days), treatment 4 (105days) and treatment 5 (135 days). It was concluded that addition of urine, feed refusal and Trichoderma viridae & Pleurotus fioridae along with fortnightly turning of manure resulted in significantly reduced period of decomposition and manure was ready for field application.en-USVeterinary ScienceLivestock Production and ManagementArticle
