A model scheme for cultivation of Oyster mushroom (Pleurotus sajor caju) with commercial viability has been prepared keeping in view the agro-climatic conditions and other related aspects for successful cultivation of the mushroom and its subsequent marketing. The effect of different substrates on yield and nutritional values of Pleurotus sajor-caju was investigated in this study. The sawdust of Triplochiton scleroxylon, coconut-husk and corn-cob were used as substrates for mushroom cultivation. Each treatment was replicated five times. Each of the sample consisted of 400g weight of substrate per bag. The produce of the mushroom, mycelia growth, diameter of the pileus, length of stipe, mushroom height as well as proximate analysis of the mushroom were analyzed. The result obtained showed that protein content (%) were found to be higher in coconut-husk followed by corn-cob and sawdust with values of 40.10%, 30.12% and 29.61% respectively. The results indicated that the mean yield (g) produced from corn-cob substrates were found to be higher followed by yield produced from sawdust and coconut husk with their yield values of 108.74±7.87, 60.76±4.62 and 56.66±3.48 respectively. The biological efficiency (%) obtained is an indication that the P.sajorcaju utilizes the given substrates effectively. The highest B.E was found in corn-cob followed by sawdust and coconut husk with value of 85.40, 67.50 and 65.25% respectively. The length of stipe, diameter of pileus and mushroom height showed that the mushroom produced from all the substrates used were of good sizeable stage and were found to be marketable despite the differences in nutritional composition of mushroom samples. Hence, the overall nutritional values of the mushroom were good.
