Abstract

Stem rot disease in oil palm seedlings is a serious problem in the oil palm industry which attacks oil palm plants in several regions in Indonesia such as Riau, Lampung and North Sumatra with an attack intensity ranging from 20%-30%. This disease is caused by a fungus, namely Ganoderma boninense. The aim of this research based on the problem formulation above is to determine the effect of growth and development of oil palm seedlings due to attacks by G. boninense which was inoculated with the antagonistic fungus Trichoderma spp. with intercropping of ginger and taro. This research used a completely randomized design (CRD) method consisting of 18 treatments inoculated with the antagonistic fungus Trichoderma spp. and planted in tumpeng sari (5 ginger intercropping treatments, 5 taro intercropping treatments and 9 without intercropping and 1 control) which was repeated 10 times. The 4 antagonist isolates used were A) Ganoderma boninense isolate B) TLTF3 isolate, C) TLTF8 isolate and D) TLRF3 isolate. The results of this study were that inoculation of antagonistic fungi and intercropping of ginger and taro had no significant effect on the percentage of diseased leaves, attack scores and leaf area. However, the stem height and stem diameter experienced significant differences. The conclusion of this research is that treatment with the antagonistic fungus Trichoderma sp. intercropped with ginger and taro, namely the JaF3 and Kel-F8 treatments, can increase the growth of oil palm seedlings although they do not significantly inhibit root rot infection caused by G. boninense.
