abstract
Present study was conducted in the laboratory as well as in mushroom house to determine the effect of different agricultural wastes (wheat straw, rice straw, sugarcane bagasse, maize straw and sorghum straw) on growth, production and quality of oyster mushroom (Pleurotus florida). The culture was maintained on Malt Extract Agar medium. Spawn was prepared on wheat grains. Spawn running took less time i.e. 20 days on wheat straw as compared to other substrates. The appearance of pinhead and their maturity also took less time i.e. 29 days and 30 days, respectively on wheat straw. Maximum yield i.e. 1360 gram was recorded on wheat straw. The first flush gave the maximum yield in all treatments and there was a progressive decrease in the yield of successive flushes. The maximum biological efficiency of 136% was observed in case of wheat straw. The maximum moisture (93.44%) and ash (1.006%) were recorded in oyster mushroom obtained from sorghum straw. Percent protein content (8.75 gram), crude fat (10%) and crude fiber (3.5%) were maximum in oyster mushroom grown on sugarcane bagasse, maize straw and wheat straw respectively.
