The substrates viz., Paddy straw, coir pith and jatropha husk alone and mixtures of these were used for the cultivation of Hypsozygous ulmarius mushroom. The maximum Hypsozygous ulmarius mushroom yield (558 g/bag) with bio-efficiency of (115.09%) was recorded with the substrate combination of paddy straw + jatropha husk, followed by paddy straw (541.67g/bag yield and bio-efficiency of 111.66%) alone, which is on par to each other. Significantly least yield (237g/bag) and bio-efficiency (48.83%) was recorded in coir pith alone compared to paddy straw and paddy straw in combination of jatropha husk.
