- Intention of this research was to know influence of exploiting of fungi of ectomycorrhiza attributed to level of P to growth plant £ grandis. This research was executed at glass house, Faculty of Agriculture, University North Sumatra, since September to December 2004. By using complete randomized design (CRD) factorial with 2 factor that was fungi of ectomycorrhiza and fertilize of phosfor. Result of research indicate that treatment of interaction among inoculation of ectomycorrhiza fungi and fertilizer of phosfor to planting E grandis, giving real influence to high increase of crop, increase of leaf amount and increase of diameter, where treatment of A4B2 or 3 tablet of mycorrhiza and 0.5 mg fertilize Phosfor (P) represent best treatment to growth E grandis. Giving of mycorrhiza inoculation to crop £ grandis give influence to high increase, increase of leaf amount, increase of diameter and P content, where best dose was treatment of A2 or 3 tablet of mycorrhiza. Giving fertilize of P to planting £ grandis give influence to high increase and increase of leaf amount, where best dose was treatment of B4 or dose fertilize 0.5 mg. High increase value of crop was highest to be got at treatment of A4B2 (3 tablet of mycorrhiza and 0.5 mg fertilize P) equal to 64.95 cm and lowered at treatment of A2B1 (1 tablet of mycorrhiza and without fertilize P) that was 14,47 cm. increase of leaf amount was highest to be got at treatment of A4B2 (3 tablet of mycorrhiza and 0.5 mg fertilize P) equal to 67 piece of and was lowered at treatment of A2B3 (1 tablet of mycorrhiza and 0.15 mg fertilize P) that was 14,33 piece of. Highest treatment for the increase of diameter got by treatment of A4B2 (3 tablet of mycorrhiza and 0.5 mg fertilize P) equal to 0.48 cm and was lowered for the treatment of A2B2 (1 tablet of mycorrhiza and 0.5 gr fertilize P) and A3B2 (2 tablet of mycorrhiza and 0.5 mg fertilize P) with value 0.24 cm. Highest coronet root ratio equal to 3.32 gr at treatment of A2B1 (1 tablet of mycorrhiza and without fertilize P) and the lowered at treatment of A2B4 (1 tablet of mycorrhiza and 0.25 mg fertilize P). Heavy run dry to totalize was highest to be got by treatment of A3B2 (2 tablet of mycorrhiza and 0.5 mg fertilize P) equal to 9.71 gr and lowered for the treatment of A1B4 (without tablet of mycorrhiza and 0.25 mg fertilize P). For the parameter of colonization, treatment of A4B2 (3 tablet of mycorrhiza and 0.5 mg fertilize P) representing highest treatment with value equal to 30.13% and lowered at treatment of A1B1 (without tablet of mycorrhiza and without fertilize P). For the parameter of P content, full marks at treatment of A4B2 (3 tablet of mycorrhiza and 0.5 mg fertilize P) equal to 1.89 mg/crop plant and the lowered equal to 0.83 mg/crop plant at treatment of A1B1 (without tablet of mycorrhiza and without fertilize P)
