Abstract:

    Effects of chicken manure content, composting process, spawn running time and depth of casing on the fruiting characteristics of the wood blewit, Lepista nuda, were investigated in this study. The mushroom was grown on the compost prepared by indoor composting and two strains LA82 and LA84 were used throughout the experiment. For both the two strains, the compost containing 20% of chicken manure (on dry basis) before composting was found to be significantly more productive and had a higher biological efficiency than the one containing 40% of the same manure, however the time for fruiting between the two composts was not significantly different for both the two strains. The average yield, biological efficiency and days from casing to fruiting were not significantly different for each of the two strains grown on the compost prepared by indoor composting with either double phase high temperature process or single phase medium high temperature process. Days from casing to fruiting for the strain LA84 were increased with spawn running time. It took the least time for the strain LA82 when the spawn running time was 28 days, while the strain LA84 when the spawn running time was 21 days. As to the depth of casing, both the two strains gave the lowest yield and took the longest time for fruiting when the compost was not cased, however , they took the least time for fruiting when the compost cased 1 cm depth with brown peat. The suggested optimum casing depth was 1-2 cm for both the two strains.
