Abstract:
The experiment was conducted at the Mushroom Development Institute,
Shabhanbag, Savar, Dhaka during January to July, 2014. The experiment consists
of two factors viz.: factor A: different media; M
1
= Paddy, M
2
= Millet and M
=
Wheat and factor B: spawn rate; S
1
= 1:1 ratio (Media : Sawdust), S
= 2: 1 ratio
(Media : Sawdust), S
3
= 3: 1 ratio (Media : Sawdust) and S
= 4: 1 ratio (Media :
Sawdust). The experiment was laid out in two factors Completely Randomized
Design with three replications. In case of different media, the highest mycelium
running rate (0.76 cm), number of fruiting per packet (70.54), number of effective
fruiting body per packet (62.61), single weight of fruiting body
4
(5.06 g),
biological yield (241.50 g), economic yield (227.00 g) and dry yield (21.83 g) was
observed from M
treatment. In case of spawn rate, the highest mycelium running
rate (0.77 cm), number of fruiting body (71.08),
1
number of effective fruiting body
(64.27),
single weight of fruiting body (4.94 g), biological yield (231.40 g),
economic yield (217.40 g) and dry yield (20.50 g) was recorded from S
treatment.
In case of combined effect, the mycelium running rate (0.83 cm), number of
fruiting body (75.63), number of effective fruiting body (71.38), single weight of
fruiting body (5.61 g), biological yield (255.90 g), economic yield (241.30 g) and
dry yield (25.10 g) was recorded from M
1
S
. Among the treatments paddy media
with mixed 4:1 ratio paddy and sawdust was found suitable for growth and yield
of oyster mushroom.
