Abstract:
The study was conducted at the Biochemistry laboratory and Mushroom Culture
House (MCH) of the Department of Biochemistry, Sher-e-Bangla Agricultural
University, Dhaka during the period from August to December 2014 to study the
effect of different sawdust on the growth, yield and proximate composition of
white oyster mushroom (Pleurotus ostreatust. Mother culture of white oyster
mushroom was collected in National Mushroom Development and Extension
Center (NAMDEC), Savar, Dhaka. The experiment consists of SLX different type
of sawdust with five replications. The experiment considered the following
treatments: To: Mixture of all sawdust, T,: Mango sawdust; T2: Raintree
sawdust; T3: Segun sawdust; T4: Gamari sawdust and Ts: Mahogony sawdust.
The experiment was laid out in single factor Completely Randomized Design
(CRO). The highest average number of fruiting body per packet (57.20) was
observed in Ts, whereas the lowest (47.00) in T2. The highest average weight of
fruiting body (4.45 g) was observed in Ts While the lowest (3.76 g) in T•. The
highest biological yield (227.68 g) was observed in T5• while the lowest (204.78
g) in T4• The highest economic yield (207.58 g) was observed in Ts, while the
lowest (181.96 g) in T4• The highest BCR (4.25) was observed in Ts. whereas the
lowest (3.62) in T4• The highest moisture content (87.77%) was observed in T,.,
while the lowest (85.84%) in Ts. The highest dry matter content (14.16%) was
observed in Ts, whereas the lowest (12.23%) in T4• The highest protein content
(24.97%) was observed in Ts, while the lowest (24.U%) in T•. The highest lipid
content (6.15%) was observed in Ts. while the lowest (5.72%) in T~. The highest
calcium content (17.33 mg/IOO g) was observed in To, while the lowest (15.72
mg/IOO g) in T•. The highest magnesium content (14.50 mg/IOO g) was observed
in Ts, while the lowest (13.35 mg/IOO g) in T4• The highest iron content (47.46
mg/IOO g) was observed in T .. while the lowest (44.89 mg/lOO g) in T4•
