Evaluation of white oyster mushroom production under different substrate types: a completely randomized design vs. simulation experiment
Main Article Content
Abstract
The cultivation of white oyster mushrooms has gained relevance for its economic, nutritional and ecological benefits. This study aims to identify the most efficient substrate to maximize mushroom production using a Completely Randomized Design. Three substrates (straw, sawdust and peanut shells) were evaluated with two replicates per treatment. Data analysis included analysis of variance, testing of assumptions, post-hoc tests for significant differences and analyzed the possibility of simulating this experiment under a certain distribution. The results of the exploratory analysis indicated that straw presented the highest average yield of 212.33 g, while peanut shells showed the lowest variability, ensuring greater stability in production. Statistical tests confirmed compliance with the assumptions of normality, constant variance and independence. Tukey's test revealed significant differences between substrates, highlighting that straw and sawdust maximize the production of white oyster mushrooms. This study highlights the importance of substrate selection in the optimization of mushroom cultivation and suggests simulation under normal distribution as a tool to reduce experimental costs and improve efficiency.
