Abstract

The area of oil palm plantation in Indonesia is increasing as its crude palm oil demand is also increase not only for vegetable oil but also for biofuel. In order to make the cultivation sustainable and echo friendly, the application of arbuscular mycorrhiza fungi (AMF) is strongly recommended as this fungi can help plant absorb more nutrient and water efficiently from the soil, hence the application of fertilizer can be reduced to at significant level. To get maximum benefit from the fungi, a proper application technique is needed. In these studies, we found that AMF (Glomus sp. and Enthropospora sp.) inoculum application to the germinated seed at the time of planting at prenursery failed to form symbiosis, no AMF infection was detected inside the root until 5 months after inoculation. In the next experiment, 10 fresh AMF spores (Glomus sp. Enthropospora sp. and Gigaspora sp.) were inoculated directly on the radicle of the germinated seed. We also found no infection of AMF until 3 month after inoculation. Another experiment were carried out by inoculating Glomus sp. and Gigaspora sp. to the one month old oil palm seedlings and the root infection was observed every two weeks until 8 weeks after AMF inoculation. The results showed that 6.7 % and 6.6% infection were detected 2 weeks after inoculation for Glomus sp and Gigaspora sp. respectively and the root infection increased by the time, 15.8% for Glomus sp. and 8.4% for Gigaspora sp. at 8 weeks after AMF inoculation.
