PERFORMANCE OF OYSTER MUSHROOM (Pleurotus ostreatus) ON DIFFERENT PRETREATED SUBSTRATES (Pages : 16 - 24)

The experiment was conducted from April 20 to June 28, 2010 at Microbial Biotechnology Laboratory of Genetic Engineering and Biotechnology Department, Khulna University, Khulna, Bangladesh. Twelve different treatments with lime were evaluated to find out the growth and yield of mushroom. The mycelium running time and days required completion of full running of mycelium. Time required for the initiation of premordia to harvesting and number of premordia and number of effective premordia, Biological yield of mushroom were greatly influenced by different pretreated substrates. The highest yield (119gm) and return (12.85Tk) were obtained from the treatment of rice straw + 10% poultry litter + 1% lime. The highest mycelium running rate was observed in the treatment of banana leaf mid ribs + 10% horse dung + 1% lime. The minimum duration of mushroom production found in banana leaf mid ribs + 10% cow dung + 1% lime. However, the rice straw + 10% poultry litter + 1% lime and rice straw + 10% horse dung + 1% lime were the best treatments for the growing of oyster (Pleurotus ostreatus) mushroom and they are economically viable.
