Performance of oyster mushroom species in the summer season using spore culture and vegetative tissue culture methods

Performance of four oyster mushroom species such as Pleurotus ostreatus, PO-2 (S1), P. djmour, Pop-1 (S2), florida, FLO-2 (S3) and ostreatus PO-10 (S4) with two culture methods like spore (C1) vegetative tissue (C2) was investigated. The experiment conducted in Mushroom Development Institute (MDI), Savar, Dhaka from April to June, 2021 CRD method. Considerable variations on different parameters related growth yield attributes were recorded.The least time required (56 days) pure first harvest recorded S2. minimum days for mycelium running completion spawn packet (20.25 observed the treatment combination S2C1 whereas maximum (28.5 S3 C2. From harvest, highest duration (77.75 S1C2 lowest (54.50 S2C1. diameter pilea ranged 6.2 cm 7.3 significant difference.
