Application of Vesicular Arbuscular Mycorrhiza to the Growth and Essential Oil Content of Rosemary (Rosmarinus officinalis L.)

Abstract

Vesicular arbuscular mycorrhiza (VAM) is one of the fungi groups that lives in soil. VAM plays a major role to increase nutrition and water absorption, and the production of plant growth substances. This research was conducted to determine the optimal dose of vesicular arbuscular mycorrhiza (VAM) on the growth and essential oil content of rosemary (Rosmarinus officinalis L.). The experimental design used in this study was a set of randomized complete block design (RCBD) with four replications. The factor was dose of VAM 0, 5, 10, 15, 20 g/plant. Data were analysed using of variance (ANOVA), variables indicating the significant different were analysed by orthogonal polynomial. The result showed the dose of VAM significantly affected stem diameter (mm) and affected highly significant on plant heigh (cm) and essential oil content of rosemary (%). Application VAM 20 g/plant was recommended to cultivate of rosemary.
