Centella asiatica was one of the wild plants that widely exploited from nature. The objective of this study was to obtain potential plant material that could be used as seeds with high centelloside content and obtain plant responses to biomass and centellocide production on application of phosphorus fertilizer. This research conducted at experimental field was used Non Factorial Randomized Block design, single factor, with six levels of P2O5fertilizer (0, 10, 20, 30, 40, 50 kg P2O5/ha) with 5 replication to determine the treatment effect on the content of centelloside, with harvest time 84 DAP (day after planting). If the treatment showed a significant effect on the observed variables then continued with the DMRT test. The plant material was used Pegagan Deli Serdang accession. Previous research found that the centelloside pattern (asiaticoside, madecassoside and asiatic acid) influenced by the condition of media and phosphorus content of media. The results show that at lowland of North Sumatra, phosphorus fertilizer dose level did not affect significantly on vegetative growth ofCentella asiaticabut affect the pattern of centelloside.Phosphorus treatment gave the highest production of asiticoside in leaves was on the phosphorus treatment of 50 kg/ha.
