| Summary: | Acehnese patchouli (Pogostemon cablin Benth.) is a plant used as a raw material in patchouli oil production. The quality of Indonesian patchouli oil is still below the standard as well as its yield, which ranged between 2,5%-5%. This research was conducted to determine the effect of phosphate fertilizer on PA content and the oil yield of the Sidikalang variety of Acehnese patchouli. Patchouli cultivation was done in polybags for 12 weeks with a mixed medium comprising of soil, compost fertilizer, and sand with a ratio of 2:2:1, with total volume of 8,7 L. Phosphate fertilizer was applied in 4 variations (0 g/polybag; 0,2 g/polybag; 0,4 g/polybag; dan 0,6 g/polybag) with 4 replications. Patchouli growth analysis was done based on the difference in plant height through time as well as initial and final fresh weight biomass. Patchouli oil was obtained by steam distillation, while its chemical composition was determined by Gas Chromatography-Mass Spectroscopy (GC-MS). Results showed that phosphate fertilizer significantly affected growth rate and doubling time based on plant height, fresh weight, especially root weight, and also oil yield, with the highest yield (5,28%) obtained when the plants were treated with fertilizer at 0,4 g/polybag. Fresh weight biomass increased along with the increase of phosphate fertilizer, but decreased when treated with 0,6 g/polybag. PA content increased along with the increase of phosphate fertilizer addition, with the highest content at 25,80%. It could be concluded that optimal application of phosphate fertilizer (0,4 g/polybag) enhanced growth, oil yield, and PA content. |
