The objective of this research was to find out the best type and dose of anorganic fertilizers in order to increase the yield of White Oyster Mushroom. The research was conducted in December 2007 - May 2008, at Lowokwaru, Malang, Indonesia ± 500 m a.s.l and the temperature is 24-32 °C. The research used Randomized Block Design consisting nine treatments and three replications. The treatment were: P0: no application; P1: 0.25 g SP-36; P2: 0.50 g SP-36; P3: 0.75 g SP-36; P4: 1.00 g SP-36; P5: 0.25 g NPK; P6: 0.50 g NPK; P7: 0.75 g NPK and P8: 1.00 g NPK/1000 g medium. The parameters observed are: the first time pinhead appeared, the number of fruit body, the diameter of fruit White body, total fresh weight of fruit body and the frequency of harvest. The result showed that application of NPK Fertilizers at level 0.25 - 0.75 g/100 g medium resulted the earliest first pinhead budding and the highest frequency of harvest. Application of NPK Fertilizers level 0.25g/100 g medium showed also the highest total fresh weight of fruit body production in the period of 155 days after inoculation. There was no significantlydifference of the diameter and the number of fruit body among the treatments.
