In order to determine the benefit cost ratio analysis of Pleurotus ostreatus mushroom cultivation using different substrates an experiment was conducted in the field of Campus of Live Sciences, Tulsipur, Dang. Different substrates such as straw, khar, banana leaves and tree leaves were used for mushroom cultivation. On 30th day, the mycelium completely colonized the different substrate and reached pinhead stage of mushroom. After one week of mycelium colonization first harvesting was done and yield of 755gm,130gm,211gm and 300gm were obtained on rice straw,banana leaves,tree leaves and khar respectively. Then,second harvesting was carried out on 44th day and yield of 475gm,100gm,0gm and 180gm were obtained on rice straw, banana leaves, tree leaves and khar respectively. Total yield of 1230gm, 230gm, 211gm and 480gm were found on straw, banana leaves, tree leaves and khar respectively. Cost of cultivation under different substrates was almost similar and by anlaysing benefit obtained from mushroom cultivation under different substrates, benefit cost ratio was analysed and found to be 2.47,0.46,0.42 and 0.96 under straw,banana leaves, tree leaves and khar respectively. From this research it is clarified that it is benefical to grow Pleurotus mushroom using rice straw substrate as the benefit cost ratio is higher when rice straw was used as substrate than in any other substrates.
