Abstract:
The present study was carried out at the Biochemistry laboratory and Mushroom
Culture House (MCH)of Biochemistry Department, Sher-e-Bangla Agricultural
University, Dhaka, during the month of January to May ’09 to investigate the yield
performance of oyster mushroom supplemented with different levels of liquid
minerals. All the treatments performed significantly over the control. The lowest
time from stimulation to primordia initiation (5.2 days) and primordia initiation to
harvest (3.9 days) was observed in T
4
(Wuxal Super @ 0.3%). The highest number
of primordia/packet (66.33) was observed in the T
and the highest number of
fruiting body/packet was observed in T
3
2
(70.00) while the highest weight of
individual fruiting body was observed in T
(2.25g). The highest biological yield
(129.0 g/packet), economic yield (123.7 g/packet) dry yield (12.73 g/packet) and
biological efficiency (44.48%) was recorded in the T
4
(Wuxal Super @ 0.3%).
The study also investigate the effect of liquid mineral supplements on nutritional
status the highest moisture percent was observed in T
4
(90.44%) the highest dry
matter percent was observed in T
4
3
(10.30%). Among the biochemical attributes the
highest content of protein was found in T
(23.60%), lowest lipid percentage was
counted under T
3
4
(5.16%), the highest percentage of ash was observed in T
(9.60%), the highest percentage of carbohydrate was recorded in T
highest percentage of crud fiber was recorded in T
(29.70 %). Therefore there was
not much effect of the treatments on biochemical properties of produced
mushroom. In case of elemental composition the highest percentage of nitrogen
was recorded in the T
4
4
(3.78) while highest percentage of phosphorus (0.96),
potassium (1.44) and iron (43.67) was recorded in T
and the the highest amount
(mg) of manganese (2.80) and zinc (14.17) was counted under T
3
There fore it can
be concluded that wuxal super @ 0.3% is found as a efficient supplement for
mushroom production lowering the cost increasing yield.
