EFFECT OF SUBSTRATES ON OYSTER MUSHROOM PRODUCTION

Abstract

The experiment was conducted at the Mushroom Development Institute (MDI), Savar, Dhaka, during the period from October 2019 to February 2020 to find out the effect of substrates on oyster mushroom production. The experiment consisted of two substrates viz. S 1 (Straw substrate) and S 2 (Sawdust substrate) and seven varieties, viz. V 1 (PO2), V 2 (POP), V 3 (WS), V 4 (PO10), V 5 ii (Oyster big), V 6 (PSC) and V 7 (HK-51). The experiment was laid out in Completely Randomized Design (CRD) with three replications. In case of substrate performance, the highest number of fruiting body packet -1 (4.91), effective fruiting body packet -1 (2.89), total biological yield (146.63 g), economic yield (142.40) and biological efficiency (73.31) were observed from S 1

(Straw substrate) compared to S 2 (Sawdust substrate). Similarly, in case of variety, V 1

(PO2) gave the highest number of fruiting body packet -1 (9.00), effective fruiting body packet -1 (4.30), total biological yield (212.00 g), economic yield (206.60) and biological efficiency (106.00) compared to other varieties. Regarding combined effect of substrate and variety, S 1 V 1 gave the highest total number of fruiting body packet

(10.00), number of effective fruiting body packet -1 (5.20), total biological yield (215.60 g), economic yield (209.80) and biological efficiency (107.80) compared to other treatment combinations. So, this treatment combination (S 1 can be considered as best compared to other treatment combinations and can be considered for commercial cultivation.
