Impact of Different Substrates and Mother Cultures on Yield and Yield Attributes of Oyster Mushroom

The goal of this study was to compare the yield and yield parameters of oyster mushrooms grown on various substrates and mother culture materials (Pleurotus ostreatus).

This is an experimental study with a Complete Randomized Design (CRD) (CRD).

From January 2019 to February 2020, the trials were carried out in the Laboratory, Department of Plant Pathology, Sher-e-Bangla Agricultural University, Dhaka, and the Mushroom Development Institute, Savar, Dhaka.

Methodology: For oyster mushroom cultivation, three substrates (sawdust, rice straw, sawdust + rice straw (1:1)) and three mother cultures (rice, maize, sawdust) were utilised.

The longest length of stipe was recorded utilising rice straw and sawdust mother spawn among the substrates and mother culture components (23.27 mm and 24.29 mm, respectively). The peak diameter of the stipe was calculated using sawdust + rice straw (1:1) and maize mother spawn (9.90 mm and 10.01 mm, respectively). In sawdust + rice straw (1:1) and rice mother spawn, the maximum diameter of pileus was observed (72.90 mm and 67.57mm, respectively). The thickest pileus was seen after the application of rice straw and maize mother spawn (5.60 mm and 5.47mm respectively). The sawdust and sawdust mother spawn delivered peak number of fruiting body (6.67 and 7.33, respectively). Among the substrates, rice straw gave the highest biological yield (44.40 g/packet) and sawdust gave the lowest (41.73 g/packet). Among the mother spawn, sawdust mother spawn presented the highest biological yield (45.47 g/packet) and maize mother spawn gave the lowest (39.16 g/packet). In a comparison of the combined effects of substrates and mother spawn, sawdust mother spawn had the highest biological yield (50.80 g/packet) when rice straw was used as the substrate material, while maize mother spawn had a lower biological yield (37.60 g/packet) when both sawdust and rice straw were used.

Conclusion: Rice straw and sawdust mother spawn can be recommended for oyster mushroom (Pleurotus ostreatus) production because of its appropriateness.
