  Background and Objective: Due to the ability of Pleurotus species to convert crop residues into food protein, oyster mushrooms are least expensive commercial mushrooms and also easy to grow at various temperature ranges from 20-26°C with 75-85% relative humidity. With respect to these facts the present study was undertaken to assess the influence of different inorganic additives (0.075%) viz., salicylic acid, potassium di-hydrogen orthophosphate, magnesium sulphate, zinc sulphate, potassium chloride, ferrous sulphate and copper sulphate on the yield of two Pleurotus species i.e., P. florida and P. flabellatus. Materials and Methods: The experiment was carried out by using seven inorganic additives in wheat straw for cultivation of Pleurotus species (P. florida and P. flabellatus). Observations were recorded and biological efficiency was calculated for cropping period, days for spawn run, days of pin head initiation, number of loab, number of fruiting body, average weight of fruiting body (g/FB) and yield (g kg–1 dry substrate). Results: Data revealed that 0.075% concentration of different inorganic additives was significantly increased the yield compared to control. Maximum yield (g kg–1 dry substrate) was observed in magnesium sulphate 695.00 g followed by potassium di-hydrogen orthophosphate 660.00 g while minimum yield was found in zinc sulphate 505.00 g of P. florida. In case of P. flabellatus maximum yield observed in potassium di-hydrogen orthophosphate was 665.00 g followed by magnesium sulphate 625.00 g while minimum yield was found in zinc sulphate 517.00 g. Conclusion: It was concluded from the above findings that the magnesium sulphate and potassium di-hydrogen orthophosphate were proved as potential inorganic additives followed by zinc sulphate causing significant increase in spawn run, cropping period and yield of the two test species of oyster mushroom viz., P. florida and P. flabellatus. These chemical additives were also very cost effective and having no residual effect on the quality and taste of mushroom.
