Aim: 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 bodies.

Results: 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 %.
