Study of influence of genus and mycorrhizae dosage on the growth of patchouli (Pogostemon cablin Benth.) in the seedling and post-seedling phases in inceptisols soil

Abstract

Pogostemon cablin Benth. (Lamiaceae) is the source of patchouli essential oil, which is an important and unique commodity in the fragrance industry. Patchouli plants are also cultivated on inceptisol with low nutrient content and CEC exchange. The use of mycorrhiza is expected to increase nutrient absorption, and plant performance of patchouli. This research is divided into 2 phases, namely the seedling and post-seedling phases. This study applies a Randomized Block Design (RBD) with 3 x 3 factorial and 3 replications. The observed factors were genus mycorrhizae; namely M1 (Glomus mossae), M2 (Gigaspora cf gigantea), and M3 (Glomus mossae + Gigaspora cf gigantea); and mycorrhizal dose; namely D1 (5 g), D2 (10 g), and D3 (15 g). Data were subjected to analysis of ANOVA using SPSS ver. 21.0 with Tukey’s test. In the seedling and post-seedling phases, the initiation of Glomus mossae had a significant impact on the growth of patchouli and mycorrhiza colonization. The best mycorrhizae dose is 5g which has a significant effect on the number of leaves at 135 and 150 DAP. The interaction of Glomus mossae at a dose of 10 g mycorrhizae has a significant effect on the stem diameter 135 and 150 DAP.
