Comparison of Growth, Yield, and Carbon Dioxide Emission After Cultivation of Five Edible Mushrooms

The increasing problem of carbon dioxide emissions has become a significant concern, with mushroom production identified as one of the contributing factors. This is because the mushroom production process emits carbon dioxide through respiration, and the carbon dioxide emitted by the mushrooms contributes to an increase in greenhouse gases. The carbon dioxide emitted by mushrooms can be utilized in various applications, such as supporting vegetable cultivation in greenhouses. However, the amount of carbon dioxide emitted by mushrooms varies. Thus, this study aimed to investigate the growth, yield, and carbon dioxide emissions in five edible mushrooms, namely Pleurotus pulmonarius, Lentinus squarrosulus, P. ostreatus, P. citrinopileatus, and P. cystidiosus. The experiment found that the fresh weight, dry weight, and biological efficiency percentage of P. ostreatus were the highest at 65.71, 11.18 g, and 28.22 percent, respectively. In contrast, the fresh weight, dry weight, and biological efficiency percentage of L. squarrosulus were the lowest, at 24.90, 3.80 g, and 9.90 percent, respectively. On the other hand, the carbon dioxide emitted from L. squarrosulus was the highest, ranging from 854.00 to 8369.67 ppm, while the carbon dioxide emitted from P. cystidiosus was the lowest, ranging from 606.00 to 861.00 ppm.
