. Sumiati, E. 2009. The Application of Substrate Supplement to Increase the Productivity of ThreeEar Mushroom Strains. The yield of ear mushroom (Auricularia spp.) was necessary to be improved. The goal ofthis experiment was to find out the proper supplements for substrate of ear mushrooms. A split plot design with 3replications was set up. The main plot was 3 strains of ear mushrooms, viz. Auricularia sp-7, Auricularia sp-11, andAuricularia sp-12. While the subplot was supplements, comprised of 12 kinds of supplements, viz. rice bran 10%,corn flour 10%, cassava flour 10%, extract of mungbean sprouts, mungbean flour 10%, beef extract, fresh coconutwater, NPK (15-15-15) 0.1 g/l, humic acid/bionature 0.1 ml/l, PGR Atonik 0.1 ml/l, essential microelements solution0.1 ml/l , rice hulls 10%, and control (without supplement). Research activity was carried out at Indonesian VegetableResearch Institute in Lembang (1,250 m asl) West Java, from December 2004 to July 2005. Research results revealedthat in general the application of those supplements mentioned could increase ear mushroom productivity. The highestyield was gained from Auricularia sp-11 cultivated on substrate + NPK (15-15-15) 0.1 g/l (827.0 g/kg substrate), orsubstrate+essential microelements Multitonic of 0.1 ml/l (899.9 g/kg substrate), and from Auricularia sp-12 cultivatedon substrate + beef extract (872.3 g/kg substrate). These highest yield was collected within a productive period from124 to 146 days with total harvesting times of 21 to 23
