Abstract/ Executive Summary:

Performance of 23 varieties of oyster mushroom on two substrates were studied in summer season. The objective of this study was to identify suitable variety and substrate for summer season in Bangladesh. A wide variation was observed in yield and yield attributes in different varieties as well as substrates. Among the varieties, the highest yield (235.0 g/packet), number of fruiting body (50.3), diameter of pileus (5.75 cm) were recorded when Po-10 cultivated on rice straw followed by sawdust. The highest (4.10 cm) diameter of stalk and thickness of pileus was found in Pcys-1 in rice straw substrate. The highest days (33.75) required to complete mycelium running when Po-4 cultivated on sawdust whereas the lowest (13.50days) in Pop-1cultivated on rice straw. The lowest (112.8 g/packet) yield was observed in Po-4 mushroom on sawdust. The lowest (0.30 cm) diameter of stalk was found in Po-1 on sawdust and the lowest (0.26 cm,) thickness of pileus was observed in Po-8 on rice straw substrate. Considering yield and yield attributes, strain Po-10 cultivated on both substrates may be recommended summer season in Bangladesh.

Start Date: 01-06-2011

End Date: 00-09-2011

Program Area: Variety and Species

Commodity: Mushroom

Objectives:

To find out the most suitable oyster mushroom varieties in summer season on saw dust and rice straw substrate.

Methodology:

The present investigation was conducted at culture house of National Mushroom Development and Extension Centre, Savar, Dhaka from June to September 2011. Mushrooms varieties were collected from germplasm centre of Strengthening Mushroom Development Project, National Mushroom Development and Extension Centre (NAMDEC), Sobhhanbag, Savar, Dhaka, Bangladesh. Twenty-three different oyster mushrooms strain such as Pleurotus ostreatus (Po-1 to Po-11), Pleurotus ostreatus var. white snow (Ws), Pleorotus cystidiosus (Pcys1& Pcys2), Pleurotus florida (Flo-1 & Flo-2), Pleurotus djamor (Pop-1 & Pop-2), Pleurotus salmoneostramineus (Pss), Pleurotus cytrinopileatus (Py-1 & Py-2), Pleurotus high king (Hk-51) and pleurotus eous (Peus) were tested on two substrates such as sawdust and rice straw.Spawn packets from sawdust of 500 g size were prepared, inoculated and incubated the procedure that developed and explained. Spawn packets of rice straw of 500 g size were prepared by hot water treatment. After completion of mycelium running, spawn packets were cut by “D” shaped and transferred to the culture house for fruiting body initiation. Room temperature was 30 to 35 ⁰C and relative humidity 85 -90%. Water was sprayed 4-5 times per day to maintain the temperature and relative humidity. The yield was obtained from third flush in the harvest period. The experiment was laid out following completely randomized design (CRD) with four replications. Data on days to mycelium running, days to pinhead initiation, days to first harvest after pinhead initiation, number of fruiting body, yield per packet, diameter and thickness of pileus, diameter and thickness of stalk were recorded and analyzed following standard methods using MSTAT-C computer program. Means were computed following DMRT using the same computer program.

Achievement/Findings:

Among the varieties, the highest yield (235.0 g/packet), number of fruiting body (50.3), diameter of pileus (5.75 cm) were recorded when Po-10 cultivated on rice straw followed by sawdust. The highest (4.10 cm) diameter of stalk and thickness of pileus was found in Pcys-1 in rice straw substrate. m) diameter of stalk and thickness of pileus was found in Pcys-1 in rice straw substrate. The highest days (33.75) required to complete mycelium running when Po-4 cultivated on sawdust whereas the lowest (13.50days) in op-1cultivated on rice straw. The lowest (112.8 g/packet) yield was observed in Po-4 mushroom on sawdust. The lowest (0.30 cm) diameter of stalk was found in Po-1 on sawdust and the lowest (0.26 cm,) thickness of pileus was observed in Po-8 on rice straw substrate. Considering yield and yield attributes, strain Po-10 cultivated on both substrates may be recommended summer season in Bangladesh.
