p RESULT AND DISCUSSION 1 Seedling Survival

Bogor, 21-22 October 2015 623 Figure 2: Seedling survival of four local plant species using agroforestry system plantation in forest and homegarden within one year plantation. A. excelsa is the best seedling survival of both plantations in forest and in home-garden. We suggested this species to promote establishment of local species in agroforestry plantation in Gede Pangrango Mountain site. After the best seedling survival, there is M. champaca as the second best of seedling survival and could also be the second priority species. 1.2 Growth Response Result of analysis of variance for height growth of four native species within one year plantation shows no significant different of both sites forest and home-garden. Table 2 shows that species E. angustifolius is the highest height mean growth in forest 65.71 cm and species S. sigun is the lowest height mean growth in forest 45.67 cm. It indicates that E. angustifolius can adapt well in this study on height parameter but overall four local plant species on this study shows similar height growth. Thomas et al 2014 said that local species are expected to be easier adapted by local conditions and to restore self-sustaining ecosystem function than non-native species.

There is no significant difference in forest plantation. Eventhough, species of E. angustifolius is the greater diameter mean growth 11.12 mm but data analysis shows that there is no significant difference in group of other species diameter growth. S. sigun is the lowest diameter mean growth 3.79 mm followed by A. excelsa 7.79 mm. Contrary result of ANOVA for homegarden plantation, E. angustifolius shows significant different than others p=0.071. Species S. sigun 2.30 mm and A. excelsa 6.64 mm also were represented the two species lowest on diameter growth. Among four local species on this study, overall species E. angustifolius shows the better on height and diameter growth.
