Jabon tree(Anthocephalus cadamba Miq.) is a native and fast growing species in Indonesiathat is preferred by the local community because of its good adaptability and economicprofitability. However, information on this tree and its appropriate silvicultural practices are stilllacking. Therefore, the aims of this study were to (1) document the existing silviculturalpractices used by local communities, (2) investigate tree growth performance among differentsites, and (3) examine the linkage between silvicultural practices and soil fertility and theireffects on stand quality in West Java. The results obtained from interviews indicated that mostof the jabon plantations are owned by outsiders from Jakarta or other cities. In addition, thereare three types of management: partnership, hiring employees and direct management. There areonly a few practitioners with silvicultural training; however, all practitioners have implementedbasic silvicultural practices. Jabon plantations in West Java were inventoried and 53 plots wereestablished across 19 sites. This species was introduced into Java in 2008; therefore, tree ageranges from 0.5 to 3.5years. The mean diameter ranges from 2.45 to 14.57cm with a maximumof 29.3cm, and the mean height ranges from 1.29 to 12.62m with a maximum of 18.68m inSitugede. Regression modeling was performed using dominant height, and the Chapman modelwas selected to generate a site index curve: Hd=10.6982(1-exp(-0.8915t))1.3078, with an R2 valueof 0.6513. This model divided the 19sites into three categories, i.e., good, medium and poor. Based on these results, there are 2 good, 11 medium and 6 poor sites. Three DBH-ageequations were generated based on site classification. A comparison between good and poorsites suggests that site conditions and soil fertility have more significant effects on the growthof jabon than silvicultural practices such as fertilization and site maintenance.
