Abstract

An experiment has been conducted to investigates the mycelium mushroom growth on 4 types of local organic wastes as well as Barley grains for comparison purpose. Also, the experiment was conducted to prepare 6 types of substrates as well as a comparison substrate (80% of Oak sawdust + 20% of wheat bran) for cultivation Ganoderma lucidum mushroom. The experimental results of mycelium growth on a different set of local organic wastes show that the minimum growth-period was 13.34 days with the substrate SP (80% of Palm trunk sawdust + 20% of wheat bran) such that the mycelium was diffused on the substrate in cottony compact, while the mycelium growth continue to 32 days with the PN substrate (80% of date nuclei + 20% wheat bran) with a significant negative variation (P>0.05) with poor growth. The Palm trunk sawdust and Barley grains were used as a source to produces a spawn based on the mycelium growth results. The best production of the fresh fruiting bodies was 65.53 g Kg-1 dry substrate with the substrate B (80% of Palm trunk sawdust + 20% of wheat bran) for two times of harvesting, while the production has reduced significantly (P>0.05) and the lowest production was achieved 17.9 g Kg-1 with the substrate C (80% reeds straw + 20% wheat bran). It should be noted that the production of substrates that spawned with the spawn-which its source is the Barley grains- has achieved a superior production (P>0.05) with an average 38.85 g Kg-1 substrate as compared to the production of the substrates that spawned with the spawn the one that its source is the Palm trunk sawdust.
