PERFORMANCE OF DIFFERENT MEDIA FOR MOTHER CULTURE PRODUCTION OF DIFFERENT MUSHROOM SPP.

Abstract

The experiment was conducted at Mushroom Development Institute, Savar, Dhaka, Bangladesh during the period from June, 2019 to May, 2020. The experiment was laid out following completely randomized design with four replications. Three mushrooms species viz, oyster mushroom, straw mushroom and button mushroom were grown for mother culture production on three different media of rice grain, wheat grain and sawdust respectively. All parameters were significantly influenced by different media with different mushroom variety except length of stalk and diameter of pileus of straw mushroom. Combined effect of straw mushroom and wheat grain media gave the highest potential result in mycelium run rate (0.72cm/day), total number of effective fruiting body (72.8), biological yield (940.10g), economic yield (935.47g), length of stalk (3.20cm), diameter of stalk (1.96cm), and thickness of pileus (1.68cm). In wheat grain media, button mushroom also gave the highest biological yield (830.20g). Oyster mushroom, button mushroom and straw mushroom grown separately in three different media, among these oyster mushroom gave the highest biological yield with rice grain media which was 144.33g and 140.43g, respectively. In wheat grain media, straw mushroom and button mushroom gave the highest biological yield which were 940.10g and 830.20g respectively. All the three mushroom spp. showed lowest biological and economic yield in sawdust media. In case of oyster mushroom the highest biological efficiency was found in rice grain media 72.2% but straw and button mushroom, the highest biological efficiency was found in wheat grain media which was 23.5% and 37.7% respectively. The lowest biological efficiency for oyster, straw and button mushroom was found in sawdust media which were 57.2, 13.7% and 25.2% respectively. According to this result, it was clearly indicated that oyster mushroom gave higher production in rice grain media, straw and button mushroom both gave higher production in wheat grain media and it was more economic than other media substrate.
