Abstract

This study aimed to determine the effectiveness of cocopeat growing media combined with rice straw and sawdust, as well as the effect of NPK fertilizer application on the growth and yield of straw mushrooms (Volvariella volvacea) using variations of 15, 25, and 35 grams of NPK fertilizer, a temperature of 35°C, and 87% humidity. Observed parameters included mushroom height, diameter, harvest weight, number of fruiting bodies, water content, and ash content. The results showed that the combination of P6 and P8 growing media (cocopeat and rice straw with 25 grams of NPK fertilizer) produced the best growth, with mushroom height reaching 3.2 cm, a diameter of 3.7 cm, a harvest weight of 170 grams, and a total of 15 fruiting bodies. The highest water content was 89% and the ash content was 31.73%. This study demonstrates that the combination of organic media and the correct fertilizer dosage significantly influences straw mushroom productivity. Keywords: Cocopeat, Straw Mushroom, Rice Straw, NPK Fertilizer, and Sawdust.
