Abstract: Oyster mushroom cultivation is a sustainable practice that converts agricultural waste into valuable resources, enhancing food security and economic stability. This research examined oyster mushroom growth and production using peanut hulls and nuts as substrate supplements. The study assessed growth parameters (stipe length and diameter, pileus diameter and thickness) and production parameters (number of mushrooms per cluster, number of clusters harvested, and weight per cluster) on different substrate formulations: sawdust-molasses-limestone (S1), sawdust-molasses-limestone with 2% peanut hull (S2), sawdust-molasses-limestone with 2% nut (S3), and sawdust-molasses-limestone with 2% molasses (S4). Substrates were prepared using a completely randomized design through drying, mixing, and fermentation. The sawdust and molasses substrate produced the longest stipe and largest pileus diameter, while the sawdust and nuts substrate resulted in the largest pileus diameter, highest number of mushrooms per cluster, and greatest cluster weight. ANOVA analysis indicated no statistically significant differences between substrates, suggesting similar effects among the combinations. The study recommends using sawdust and nuts for optimal growth and production, avoiding molasses due to its inhibitory effects on cluster formation. Further research should investigate the nutrient contributions and pH levels of each substrate component to refine recommendations. Mushroom cultivators should monitor substrate pH and incorporate nuts to enhance production, with agricultural extension services providing training on effective substrate optimization.
