Effects of Relative Humidity on the Moisture Content of Substrate Culturing Bhutan Oyster Mushroom (Pleurotus pulmonarius)
Main Article Content
Abstract
The study examines how relative humidity affects the moisture content of the substrate used for culturing Bhutan oyster mushrooms (Pleurotus pulmonarius). The experiment was planned in a Completely Randomized Design (CRD) consisting of 3 levels of experimental units with 5 repetitions per level. The first treatment had a relative humidity of 76–80%. The second treatment had a relative humidity of 81–85%. The third treatment had a relative humidity of 86–90%. Control the relative humidity within the experimental unit by turning the water sprayer on and off (by spraying water starting at 8:00 a.m. to 5:00 p.m.) for 15 days. An analyzed of the moisture content of substrate culturing Bhutan oyster mushrooms, found that the first treatment had an average of 58.23±0.20%, the second treatment had an average of 58.33±0.18%, and the third treatment had an average value of 58.15±0.23%. When considering the 3 levels of experimental units, there was no statistically significant difference at the 95 percent confidence level (p>0.05). Increasing the relative humidity at various levels has no direct effect on the moisture content of the substrate culturing Bhutan oyster mushrooms.
