The objective of the research was to study the effect of mycorrhiza inoculation, rockphosphate and organic matters in three locations of dry land area. This research was conducted in three months. Gnetum gnemon was selected for this research due to the multipurpose and the resistance of this species to the dry land. One year old seedlings of G.gnemon were planted in three dry locations and then rockphosphate of 0,50 and 100 g were applied for treatment. Three levels of organic matter application were applied in combination with mycorrhiza inoculation. Organic matters for treatment were collected from decomposed cow dung . Mycorrhiza inoculation for this treatment was soil inoculum collected from topsoil ( 0-20 cm) under G.gnemon trees. The results showed that location had significant effect to the growth of G. gnemon. Mycorrhiza inoculation significantly affected to diameter growth in the field but not in height growth. On the contrary decomposed cow dung treatment affected significantly to the height growth but not the diameter growth. Rock-phosphate fertilizer did not show significant effect to growth. However there were interaction among location, inoculation, decomposed cowdung, rockphosphate in both parameter growths. Key words: Gnetum gnemon, mycorrhiza, cowdung, rockphosphate
