Oyster Mushroom (Pleurotus ostreatus) Growth and Production On Straw and Brands Substrate Supplied with Nasa Liquid Organic Fertilizer (POC)

This study aims to analyze the effect of adding NASA Liquid Organic Fertilizer (POC) supplements substrate on oyster mushroom (Pleurotus ostreatus) growth and production. The research design used in this was a completely randomized (CRD), with four levels treatment addition POC. doses were 0% POC as control (A), 2.5% (B), 3% (C), 3.5% (D). Each repeated times obtain 16 units. unit consisted 5 Baglogs, so total sample observed 80 Baglogs. Based parameters study, including length mycelium spread (LPM), beginning emergence pinheads (AMP), number (JP), diameter hood (DTJT), weight (BBJT), substrate. Growth has no significant production mushrooms ostreatus).
