Abstract:
The composition of baglog media greatly affects the yield and quality of oyster mushrooms. Then the use of growth regulators in the production of oyster mushrooms is rarely done. This research was to examine the effect of gibberellins concentration and baglog media composition on the growth and yield of oyster mushrooms. The results showed that the interaction between gibberellin concentrations and baglog media composition showed better results than the control treatment at harvest interval, total harvest, and dry weight. Then the concentration of gibberellins had no impact on increasing mycelium growth and biological efficiency. In the composition of baglog media, the use of bagasse and cocopeat can replace sawdust by up to 50%. With bagasse which was only able to give a good response on yield and biological efficiency, namely 42.82% and cocopeat, which only showed a good response on mycelium growth, namely 59.43% at 12 day after inoculation and 99.24% at 22 day after inoculation.
