comparative study on cultivation and yelid preformance of oyster mushroom (Pleurotus floridanus) by using different supplements to sorghum apswn and rice straw

Popularity of oyster mushroom is increasing for its ease of cultivation, high yelid potential as well as high nutritional and medicinal values. This investigation was carried out to evaluate the effect of some supplementto spawn (sorghum grains) and also spawn level on Pleurotus floridanus yelid and biological effeciency. The highest average yelid (721g/500g straw) and biological efficiency (144%) were achived with sorghum supplemented with milled cotton seeds. The range of 5-7% spawn level was the best. In addition Pleurotus floridanus was cultivated on rice straw alone or in combinations with some selected agro wastes viz., cotton stalk, broad bean grain husks, rice bran. The highest yelid and intracellular protiens were achived in rice straw amended with broad been grain husks followed by the cotton stalks
