The present study was formulated with an aim to evaluate different locally
available residues from trees such as mixed saw dust, saw dust of coconut
wood log, coconut leaf stalks/petiole, coconut coir waste, saw dust of areca
nut wood log for cultivation of medicinal mushroom Ganoderma lucidum.
Methodology: Locally available agro residues viz., mixed saw
dust, saw dust of coconut wood log, chopped coconut leaf stalks/petiole,
coconut coir waste, saw dust of areca nut wood log were mixed with 20% wheat
bran as supplement and packed in bags at 175 g/bag, autoclaved and
aseptically inoculated with grain spawn of G. lucidum and provided with
different temperature and humidity conditions for production of fruiting
Among the substrates, coconut wood log saw dust supported early spawn run
within 46.5 days and early pinhead production on day 54 followed by pinhead
expansion in 62.3 days and first harvest within 70.5 days. The average number
of fruiting bodies were also higher (5.75 numbers/bag) with an average weight
of 13.5 g/fruiting body that gave significantly higher yield of 77.5 g/175 g
substrate with bioefficiency of 44.3% in a cropping cycle of 100.5 days
compared to other substrates.
Interpretation: The results show that coconut wood log
saw dust substrate offers great scope for artificial cultivation of G.
lucidum with a significant bioefficiency of 44.3 %.
