Pertumbuhan Bulbil Iles-Iles (Amorphophallus muelleri Blume) Berbagai Ukuran pada Beberapa Jenis Media Tanam
Abstract: 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 of bulbil. 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: U1
small (± 1.5 gram), U2 medium (± 5 gram), and U3 large (± 10 gram). The second
factor is the type of planting media which consists of three levels: M1 (soil +
litter), M2 (soil + cow manure), and M3 (soil + chicken manure).The results
showed that medium size and large size bulbil are good to be used as seeds,
while the small one can be used as seed only if it has been maintained in
special treatment. M3 planting medium (soil + chicken manure) has given the
best result compared to the other 2 treatments. Results of interaction test
showed that there were interactions of both factors on some parameters
including diameter leaf canopy, pseudo-stem diameter, root diameter and fresh
weight of bulb.
