Optimization of Growth and Production of Brown Oyster Mushrooms (Pleurotus cystidiosus) through Additional Nutrients of Rice Washing Water and Rice Groats

Abstract

This study aims to determine the optimization of growth and production of brown oyster mushroom (P. cystidionsus) plants with additional nutrients of rice washing water and to determine the optimization of growth and production of chocolate oyster mushroom (P. cystidionsus) plants through additional nutrients of rice groats. This study used a factorial Complete Randomized Design (RAL) method consisting of two factors, namely, the first factor is rice washing water / leri water (L) and the second factor is rice groats (G). Each treatment is repeated 3 times. Leri water factor consists of 4 levels, namely: A0=0 ml, A1= 30 ml, A2= 50 ml, A3=70 ml. Rice groats factor consists of 4 levels, namely: M0=0 g, M1=60 g, M2= 80 g, M3= 100 g. Data was analyzed using variance analysis (Anova) at 5%. The results showed no effect of rice washing water and rice groats on the growth rate of brown oyster mushroom mycelim, will be at a rice washing water concentration of 70ml / baglog + rice groats 100g / baglog affects the parameters of mushroom stalk height (cm), mushroom hood diameter (cm), mushroom hood thickness (cm), number of mushrooms (clump), and fresh weight of mushrooms / baglog (g).
