Abstract

The research is done in forestry laboratorial nursery of Agriculture Faculty of Muhammadiyah University of Malang. This research is started on 15 April up to 10 June 2012. The purpose of this research is to know jabon seedling (A. cadamba, Miq) growth respons as the effect of urea fertilizer dosage and media composition. The research used a factorial random group method (RAK) which is arranged in such factorial by three times repeating including two treatment factor. The first factor is urea fertilizer dosage (S) composed of 5 levels, they are : S0 (urea fertilizer dosage 0 gram/polybag), S1 (urea fertilizer dosage 0.25 gram/polybag), S2 (urea fertilizer dosage 0.50 gram/polybag), S3 (urea fertilizer dosage 0.75 gram/polybag), S4 (urea fertilizer dosage 1 gram/polybag). The second factor is the plant media composition (T) which consist of 4 levels, they are : T0 (soil 100% as controller), T1 (soil 50%, grit 25%, bran charcoal rice plant 25%), T2 (soil 25%, grit 50%, bran charcoal rice plant 25%), T3 (soil 25%, grit 25%, bran charcoal rice plant 50%). Observation does on 14 hst up to 56 hst with frequency 7 day. The research is focused on : high seedling, stick diameter, leave number, root length, dry seedling and wet seedling weight. Statistic analysis result show there are interaction between urea fertilizer dosage and media composition toward jabon seedling growth at several high seedling in the age 28 hst, 35 hst, 42 hst, 48 hst and 56 hst, leave number in the age 35 hst 56 hst, and root length, dry seedling and wet seedling weight in over observation. The best treatment combination is S3T1. Treatment S gives significant influence to almost all of research. Treatment media composition T gives significant influence to high seedling, leave number, root length, dry seedling and wet seedling weight. Conclusion from this research, the best treatment combination to gives significant influence to jabon seedling growth is S3T1 (urea fertilize dosage 0.75 gram/polybag) and media composition (soil 50%, grit 25%, bran charcoal rice plant 25%).
