Abstract

The objective of the research to find out the influence of michoriza, enrichmeni organic fertilizer, and wood vinegar combination on growth of G. arboreaseedling. The research was conducted in the. nursery, area of Foresny Research Instiude on November 2006 to January 2007. The research used the Complete Random Design (CRD) with 6 (six) treatments. The research shows that the michoriza, enrichmentorganicfertilizer and wood vinegar combination produces 50.87 cmof the best growth of tree's height. The influence organic fertifizer in treatment combination (M1N0C0vs M1N1C0) has a significant result on growth G. arborea seedling's height. The treatment combination MINICO (44,63 cm) showed a better result than the M1N0C0 (35,55 cm). The influence of wood vinegar treatment combination has not significant result on growth G. arborea seedling's height.

Abstract

Cultivation of albizia as high priority of community forest of West Java in large scale have turned into monoculture stand. These stand has become vulnerable to insect attack such as bagworm. Attack of bagworm took place in the dry season causing growth retardation which in some cases leads to tree death. The aim of this research is to examine the affect of leaf extract of Toona sureni and extract of Beauveria bassiana fungi to kill bagworm and also compare level effectively with organofosfat synthetic insecticides. The result showed that at 7 day after application, highest mortality of bagworm were found on trees treated with T. sureni leaf extract (100%) followed by B. bassiana (92,31%) and organofosfat synthetic insecticides (76,15%).
