Abstract:
The present study was carried out during the period of February to July, 2009 to
investigate the performance of different levels of wheat bran as supplement with
sugarcane bagasse on the production of oyster mushroom and analysis of their
proximate composition. The highest mycelium running rate was observed due to
sugarcane bagasse supplemented with wheat bran @ 40% (T
) (0.96 cm). The
highest time from stimulation to primordia initiation was observed in T
5
days). The lowest time from primordia initiation to harvest was in the treatment of
T4 (3.23 days). The highest average number of primordia/packet (70.67), average
number of fruiting body/packet (61.00) was observed in the treatment of T
. The
highest average weight of individual fruiting body was observed in the treatment
of T
(3.69 g). The highest biological yield (254.7 g), economic yield (243.3 g),
dry matter (23.40 g), biological efficiency (87.82%) and cost benefit ratio (8.29)
was counted under treatment of T
4
. The highest moisture content (90.45 %) was
observed in T
5
4
where as the highest dry matter percentage of (10.07 %) was found
in the fruiting body of T
. The highest content protein (30.31 %), ash (9.15 %) and
crud fiber (24.07 %) and the lowest lipid (3.90 %) and carbohydrate (32.57 %) was
found in the treatment of T
2
4
. The highest percentage of nitrogen
1
(11.5
5
(4.85), potassium (1.39g/mg), calcium (22.08mg), magnesium (20.21mg), sulfur (0.042g/mg), iron
(43.11mg) was counted under T
but the highest percentage of phosphorus was
counted under treatment of T
4
(0.92). Therefore, it can be concluded that
sugarcane bagasse supplemented with 30% wheat bran can be further used as a
better substrate for oyster mushroom production reducing cost and increasing the
yield and nutritional quality.
