DIVERSITY OF THE INDIGENOUS ARBUSCULAR MYCORRHIZAE FUNGI (AMF) IN THE RHIZOSPHERE OF CITRONELLA (ANDROPOGON NARDUS L.) IN THE DRY LAND REGIONS IN WEST SUMATRA PROVINCE, INDONESIA

Arbuscular mycorrhizal fungi (AMF), are soil microbes that have the potential to increase yield and low productivity agricultural inputs. Independent AMF exploration will provide preliminary information about the diversity of species of spores from these fungi in crop rhizosphere. This information is very important to know that the use of AMF in the crop is more effective and efficient. Nearly 96% of crops are able to symbiosis with AMF. The aim of this study was to determine the diversity of indigenous AMF in the citronella rhizosphere. Soil samples were taken from 3 citronella crop locations randomly. The results of the study found 7 species of AMF indigenous, namely Glomus sp 1, Glomus sp 2, Acaulospora sp 1, Acaulospora sp 2, Acaulospora sp 3, Gigaspora sp 1 and Sclerocystis sp 1.
