Paddy straw, ragi husk, ragi straw, groundnut shell, lawn grass and shredded paper were used as substrates for the cultivation of Hypsozygous ulmarius mushroom. Use of paddy straw + lawn grass showed significantly higher mushroom yield (538.33 g/bag) and bio efficiency (111.81 %). Chemical analysis of N, P and K of substrates, viz., ragi husk, groundnut shell, lawn grass, shredded paper, ragi straw and paddy straw was carried out before and after growing mushroom. Before growing mushroom maximum nitrogen (0.84), phosphorus (0.49), potassium (1.72 %) content were recorded in paddy straw. After growing mushrooms the maximum nitrogen (1.64%) in ragi husk, phosphorus (0.49 %) in paddy straw, potassium (2.72 %) in ragi husk.
