Abstract :
This research aims to know the effect of composition of media and dossage of
dekastar plus fertilizer on the growth of adenium. The result of this experiment was
expected to grue contribution obout information of using the composition of media
and dossage of dekastar plus fertilizer toward the the process of growing the
vegetative of adenium. The hypothesis was estimated be found the effect of
significant interaction between the composition of media and dossage of dekastar plus
fertilizer on growth of adenium. The Assumption of the composition of media or
dossage dekastar plus of fertilizer toward on vegetatif growth of adenium. The
research was conducted in Mulyoagung Dau Malang between Agustus until Novenber
2006. The elevated place about 560 m dpl. The equipment used in this research
included plastic pot, analytical weighs, ruler, jangka sorong, beaker glass, sprayer,
palstic, book and balpoint. The materials used were seedling of adenium, sand, sekam
charcoal, deskastar plus, insecticide and fungiside.
This research used the factorial randomized blok design (RBD) with tree
replication. The first faktor is composition of media consisted of three levels: M1
composition of media (sand: sekam charcoal:organic fertilizer=1:1:1), M2 (sand:
sekam charcoal:organic fertilizer=2:1:1), M3 (sand:sekam charcoal:organic fertilizer
=3:1:1), and the second factor was dossage of dekastar plus fertilizer with four levels:
D0: no fertilizer (control), D1 : dossage 1g/plant , D2: dossage 2g/plant, and D3:
dossage 3 g/plant of dekastar plus fertilizer.
Result of the research showed that there were significant interaction between
the treatment variable at increase the plant height and the leaf number. The
combination this good treatment was M3D3 for plant height and M1D3 for leaf
number. The composition of media there were significant on the bonggol diameter
and leaf number. The best composition of media was M1 (sand:sekam
charcoal:organic fertilizer=1:1:1). The treatment dossage of dekastar plus had
significant on the bonggol diameter and leaf number. Dossage 3g/plant of dekastar
plus show the result is better.
