Abstract: The research experiment was carried out to evaluate the effect of different substrates on the growth and yield of oyster mushroom (Pleurotus florida) to find out the best alternative substrates that support the growth of oyster mushroom, produces the maximum yield with highest biological efficiency and nutritional contents. A total of seven treatments replicated five times were taken under the complete randomize design. The minimum time taken for mycelium run (15 days) was in T₀ Wheat (control) and maximum was observed in T₂ Cardboard (21 days). Primordium initiation was observed on 17^th – 26^th days. The maximum time from primordial stage to harvesting stage was recorded in T₂ cardboard (35 days). Maximum yield was obtained on T₃ Banana leaves (915.23 g) with highest biological efficiency (91 %). Moisture content was found high in T₁ Grass (92 %) and showed maximum protein (30.20 %) in T₆ Cardboard + Banana leaves and highest carbohydrate in T₀ Wheat (4.46 %). The lipid contents were found maximum in T₆ Cardboard + Banana leaves (0.88g). Therefore, it can be concluded that Banana leaves substrates individual as well as in combination proved to be best for cultivation of P. florda.
