White oyster mushroom (Pleurotus ostreatus) is an edible mushroom widely cultivated due to its nutritional and economic value. This study aimed to evaluate the effect of different substrate compositions of sawdust, corn cobs, and rice husks on the growth and yield of white oyster mushrooms. The experiment was conducted using a Completely Randomized Design (CRD) with four treatments and five replications, resulting in 20 experimental units. Growth parameters observed included stipe length, pileus diameter, fruiting body mass, and the number of fruiting bodies. The results showed that substrate composition significantly affected mushroom growth and productivity. The K2 treatment, consisting of 30% sawdust, 40% corn cobs, and 30% rice husks, produced the best performance in all observed parameters. The higher proportion of corn cobs in the substrate likely provided favorable conditions for mushroom development and yield. In conclusion, a substrate composed of 30% sawdust, 40% corn cobs, and 30% rice husks is recommended for the cultivation of white oyster mushrooms because it promotes optimal growth and productivity.

Marginal soils are characterized by low nutrient availability, which adversely affects crop productivity. The incorporation of organic materials and cultivation techniques plays an important role in maintaining soil health and crop yield. This study aimed to evaluate the effects of photosynthetic bacterial fertilizers and the push-pull system cultivation technique. The research was conducted in Banjaran Village, Purbalingga Regency, utilizing a completely randomized block design. Treatments tested included S0 (control), S1 (50 mL/2L), and S2 (100 mL/2L), as well as P0 (control), P1 (lemongrass), and P2 (peanuts). Each treatment was replicated three times and analyzed using ANOVA, with Duncan's Multiple Range Test (DMRT) (α=5%) applied for significant differences. The observed variables included fresh plant weight, leaf area, fresh root weight, age of male flowers, and chlorophyll a levels. The results indicate that the application of photosynthetic bacteria significantly affects the fresh weight of the plants and the age of male flowers. However, there is no significant effect on leaf area, fresh root weight, and chlorophyll a levels. The push-pull system cultivation technique significantly affects chlorophyll a levels, although no significant differences were found in fresh plant weight, leaf area, fresh root weight, and age of male flowers.
