ABSTRACT A greenhouse pot experiment was conducted to test the effect of vesicular-arbuscular mycorrhizal (VAM) fungi on growth of corn on a Rangkasbitung Red Yellow Podzolic (RY?) soil. Soil samples were sterilized with formalin 5% and treated with lime (0 and 1,5 Ion CaC04/11a) and P fertilizer (0 and 250 kg TSP/ha). Corn plants inoculated with 2 types of VAM fungi, e.i. the indigenous VAM fungi isolates (Glomus spp.) and the introduced VAM fungus isolate (G. fasciculatum (Thaxter sensu Gerd.) Gerd. & Trappe). Plants were harvested at 42 days after planting. The inoculated VAM fungi significantly increased root fresh weight, shoot dry weight and P uptake of corn on a TYP soil. In case, G. fasciculatum was more effective compared to indigenous Glomus. However, the effectiveness of VAM fungsi was affected by the availability of P in soil_ At 15,90 ppm of available P in soil, namely in an treated soil with 250 kg TSP/ha, the VAM fungi was at the most effective in increasing growth and P uptake of corn. On the other hand, in an untreated soil or in an treated soil with lime alone, the VAM fungi not significantly increased corn growth. The effectiveness of VAM fungi on corn tended to decrease when the available P in soil was higher than 15,90 ppm, Key words : glomus fasciculatum podzolic soil- VA rnycorrhizae.
