Abstract

To investigate the effect of inorganic nutrient supplement in oyster mushroom (Pleurotus ostreatus), we have conducted some study on cultural and growth characteristics of fruitbody formation and chemical composition of media and fruitbody. When supplemented with slow releasing fertilizer, contamination rate was not different from non-supplemented medium, days for incubation time and first pinhead were faster than non-supplemented medium. And fruitbody yield and biological efficiency were increased 10∼28%, 7∼20% respectively, but biological efficiency was decreased when increased supplement ratio. The chemical compositions (total carbon, total nitrogen, ammonia nitrogen, nitrate nitrogen, potassium and phosphate) of slow releasing fertilizer supplemented medium and fruitbody were compared with non-supplemented.
