The study was carried out by using local organic wastes to investigates the growth of mycelium Ganoderma lucidum Mushroom, produce the spawn and prepare a substrate and their effect on the duration and Production efficiency. The experimental results of mycelium growth on a different set of local organic waste show that the minimum growth-period was 13.34 days with the substrate B, such that the mycelium was diffused on the substrate in cottony compact. On the other hand, the mycelium growth continues to 21.34 and 21.67 days with the substrate D and C, respectively, with a significant negative variation (P>0.05) and cottony non compact mycelia growth on the substrate parts. The source of the produced spawn was adopted for mycelium growth results. The results of the substrates characteristics during the stages of substrates preparation have been demonstrated that the highest value of pH was achieved by 6.93 with the substrate A. Moreover, the results show that the maximum moisture content of the substrates was obtained with the substrate B about 67.36%, and that the minimum time period for duration of the crop by two time harvested Done during 107.16 days and 107.33 days on substrates B and E respectively. While The difference was significant (P>0.05) with substrates C and D The second harvest ended after 108.66 days and 108.83 days from substrates Spawning respectively. It was not recorded significant with different source spawn. The best bio-efficiency has been achieved an average of 6.55 % with substrate B. the average substrates efficiency that spawned it by spawn- which its source is the Barley grains achieved 3.88 % Significantly superior (P>0.05) on substrates efficiency that spawned it by spawn- which its source is the Palm trunk sawdust.
