| dc.description.abstract | Mushroom is a heterotrophic-group organism with no chlorophyll that can
grow on media that have a high cellulose content, one of which is agricultural
waste. In addition to usual straw used as a medium, mushroom can also be grown
on various media including banana leaves, coffee skins, reeds and so on. This
research used straw as medium combined with reeds (Imperata cylindrica) which
are still included in Poaceae family. As a media mix for the availability of
nutrients in the media, rice bran was used, and the addition of plant growth
regulator (PGR). The composition of media and PGR was assumed to be able to
determine the growth and yield of mushroom.
The objective of this research was to identify the composition of media types and
concentrations of PGR that could enhance the growth and yield of mushroom. The
research was conducted in factorial with the basic pattern of Randomized Group
Design (RGD), which consisted of 2 factors with 3 replications. The first factor
was the composition of medium and the second factor was the concentration of
PGR.
The research results showed that, (1) there was no interaction between the
composition of media type with the concentration of PGR on the growth and yield
of mushroom, (2) the composition of the media provided insignificant effect on all
parameters of observation except the parameter of total number of mushroom
body, where M2 was straw treatment: reeds (1:1) gave the best results with the
number of mushrooms of 65, and (3) the treatment of PGR concentration did not
provide significant effect on growth and production of mushroom. To obtain
maximum results, the thing that needs consideration is the composting medium.
Medium composting was tailored with the type of media, like reeds that have
harder textures should be given longer composting time or the addition of
decomposing microorganisms so that composting can be perfect. | en_US |
