PERTUMBUHAN BULBIL ILES-ILES (Amorphophallus muelleri Blume) BERBAGAI UKURAN PADA BEBERAPA JENIS MEDIA TANAM

Iles-iles or porang produces various sizes of bulbils, and farmers usually use only large ones. In this study, all sizes of bulbil: small, medium and large were grown on several planting media types. The purpose of this experiment is to obtain the best bulbil growth and the most suitable media for the initial growth of plant material in the form ofbulbil. In addition, this study aims to test the interaction of both factors, bulbil size and type of planting media on bulbils produced. The experiment was done in the Faculty of Agriculture UPN "Veteran" Yogyakarta experimental field in Condongcatur, at 115 m asl, at the beginning of rainy season of 2010/2011. The experiment was done with two-factors and three replications constructed in Randomized Block Design. The first factor was the size of the bulbil (U) consisting of three levels: UJ small (± 1.5 gram), U&#832
