Abstract/ Executive Summary:

Ten different species of oyster mushroom have been cultivated on rice straw and the yield and yield related attributes were compared. The minimum days required from stimulation to primordia initiation (DRSPI) (3.50) was recorded in Pleurotus ostreatus (whitesnow), Pleurotus geesteranus and Pleurotus citrinopileatus and the maximum DRSPI (10.25) was recorded in Pleurotus erryngi and Pleurotus sajor-caju. The minimum days required from stimulation to first harvesting (DRSFH) was found in Pleurotus citrinopileatus (5.50) and the maximum DRSFH (15.25) was found in Pleurotus erryngi closely followed by Pleurotus sajor-caju (14.25). The number of effective fruiting bodies was highest (47.00) in Pleurotus citrinopileatus and it was lowest (1.00) in Pleurotus erryngi. The length of stipe ranged from 3.45 to 6.80 cm. The highest length of stipe (6.80cm) was found in Pleurotus erryngi followed by Pleurotus ostreatus (5.50cm) and the lowest length of stipe was found in Pleurotus sajor-caju (3.45cm). The diameter of stipe, pileus and thickness of pileus ranged from 0.35 to 4.60cm; 4.00 to 11.00cm and 0.35 to 1.40cm respectively. The highest diameter of stipe (4.60cm) and pileus (11.00cm) were found in Pleurotus erryngi. The biological and economic yields and biological efficiency were the highest, 191.00g and 183.5g and 127.30% respectively, in Pleurotus ostreatus (whitesnow).

Program Area: Variety and Species

Commodity: Mushroom

Objectives:

1. To evaluate the performance of different species of oyster mushroom on rice straw and

2. To find out the best species of oyster mushroom for cultivation on rice straw.

Methodology:

The experiment was conducted in the culture house of National Mushroom Development and Extention Centre, Sobhanbag, Savar, Dhaka, Bangladesh from January to April 2010. In this experiment rice straw was used as substrate for the cultivation of 10 different species of oyster mushrooms. The straw was chopped to 3-4 inch length and then poured in water at 60°C for one hour and then drained out the water and kept it to get cool slowly. After about 20 hours the straw was spread over floor to reduce the moisture level at 65%. The polypropylene bags of 9"x12" size was filled with pasteurized straw inoculating the mother culture of 10 different species of oyster mushroom, Pleurotus ostreatus, Pleurotus geesteranus, Pleurotus high king-51, Pleurotus florida, Pleurotus ostreatus (whitesnow) Pleurotus citrinopileatus, Pleurotus erryngi, Pleurotus cystidiosus, Pleurotus sajor-caju, Pleurotus sapidus and their mouths were plugged by inserting absorbent cotton with the help of plastic necks. The packets were kept in a dark room at 25°C for incubation. When colonization of mycelium was completed, the spawn packets were taken to a culture house and were opened by ‘D’ shaped cut on the shoulder and removed the sheet. The relative humidity and temperature of the culture house were maintained at 80-90% and 20-25°C respectively by spraying water. Diffused light, about 200 lux and proper ventilation in culture house were maintained. After harvesting of mushroom, the residues were removed from the packet and temperature and relative humidity were maintained as before. The experiment was laid out following completely randomized design (CRD) with 4 replications. Yield and yield parameters were taken on the basis of two flushes except in Pleurotus erryngi where only one flush was obtained. Data on days required from stimulation to primordia initiation and first harvest, number of primordia and effective fruiting body, length of stipe, diameter of stipe and pileus, thickness of pileus, biological and economic yield (g/packet) were recorded. Data were analyzed using MSTAT-C computer program. Means separation were computed following Duncan’s Multiple Range Test (DMRT) using the same computer program.

Achievement/Findings:

The number of effective fruiting bodies was highest (47.00) in Pleurotus citrinopileatus and it was lowest (1.00) in Pleurotus erryngi. The length of stipe ranged from 3.45 to 6.80 cm. The highest length of stipe (6.80cm) was found in Pleurotus erryngi followed by Pleurotus ostreatus (5.50cm) and the lowest length of stipe was found in Pleurotus sajor-caju (3.45cm). The diameter of stipe, pileus and thickness of pileus ranged from 0.35 to 4.60cm; 4.00 to 11.00cm and 0.35 to 1.40cm respectively. The highest diameter of stipe (4.60cm) and pileus (11.00cm) were found in Pleurotus erryngi. The biological and economic yields and biological efficiency were the highest, 191.00g and 183.5g and 127.30% respectively, in Pleurotus ostreatus (whitesnow). Considering all the parameters, Pleurotus ostreatus (whitesnow) performed best among the species on rice straw.
