Effect of Type and Dose of Arbuscular Mycorrhizal Fungi to Growth and Yield of Citronella Grass (Cymbopogon nardus L.) in Former Mining Area Land in Sawahlunto

Aims: The study aimed to determine the type and dose of arbuscular mycorrhizal fungi (AMF) to growth and yield of citronella grass (Cymbopogon nardus L.) in former mining area land in Sawahlunto, West Sumatera, Indonesia.

Study Design: Factorial completely randomized design.

Place and Duration of Study: The research was conducted in shade net house of Faculty of Agriculture, Andalas University, Padang, West Sumatera, Indonesia from September 2021-January 2022.

Methodology: Two factors were used in the study. First factor was types of Arbuscular mychorrhizal fungi (AMF), Glomus sp., Gigapora sp. dan multispores (Glomus sp. + Gigaspora sp.) and the second factor was AMF doses that consisted of four degrees, 5 g, 10 g, 15 g and 20 g/plant. The experiment result was analyzed by using Analysis of variance (ANOVA) in 5% and continued by using Duncan’s New Multople Range Test (DNMRT) in 5%.

Results: Type of AMF multispores in 20 g/ plant could number of tiller. Dose 20 g/plant could plant height and number of leaves. AMF multispores only increased number of tiller and net assimilation rate.

Conclusion: Type and dose of AMF affected the agronomy parameter of citronella grass in former mining area land.
