Paddy straw, ragi husk, ragi straw, groundnut shell, lawn grass and shredded paper were used as substrates for the cultivation of Hypsozygous ulmarius mushroom. After the cultivation of mushroom, the spent substrates application with NPK was used to know the effect on growth of finger millet. The green house experiment showed significantly higher microbial population viz., bacteria, fungi, actinomycetes, Azotobacter, phosphate solubilizers and Arbascular mycorrhiza spores. Use of Hypsozygous ulmarius mushroom spent ragi husk exhibited significantly higher growth in finger millet, which recorded significantly higher plant height (90.25 cm), total fresh weight (97.33 g/ plant), root dry weight (7.75 g/ plant), shoot dry weight (23.75 g/ plant) and total dry weight (31.25 g/ plant) followed by in Hypsozygous ulmarius mushroom spent paddy straw. Application of spent mushroom substrates to soil with recommended NPK enhances the growth of finger millet.
