Total amount of Vesicular Arbuskular Mycorrhiza Fungi Spores in the Rhizosphere of Oil Palm (Elaeis guineensis Jacq.)

Vesicular arbuscular mycorrhizae (VAM) are obligate mutualistic symbionts in plant roots cortex and help the absorption of nutrients needed for plants to growth. The research was aimed calculate the spores of VAM and identification to the genus of level. This research has been carried out laboratory analysis in February 2015 to June 2015. The research was conducted by field survey. The purposive sampling area was an oil palm plantation field difference in plant ages. The sampling area was determined purposively on a sample area in palm oil plantations with the different ages of 1 year (Main Nursery), 3 years, 8 years, 14 years and 19 years. The result showed the amount of VAM spores significantly carelated to C-organic in the soil. VAM spore dominated by size 105-53?m. There were 2 genus consisting of 14 morfotipe, genus Acaulospora shows 7 morfotipe and genus Glomus 7 morfotipe, it found in the Sampling area. Keywords
