Identification of root-associated arbuscular mycorrhizal fungi in cassava (Manihot esculenta Crantz) in Manokwari Regency, West Papua, Indonesia

Arbuscular mycorrhizal fungi (AMF) are crucial for plants growing on marginal soils, especially those with a very high dependence AMF; one of them is few roots, such as cassava. This study aimed to identify the AMF associated cassava in six locations Manokwari Regency, West Papua, Indonesia. The research was carried out using an observation method and purposive sampling at 6 locations. Soil samples were taken from rhizosphere 8-month-old plants, 2 kg soil each site. Furthermore, host plant Sorghum bicolor L, trapped three months. spore morphology identification showed that North District 3 genera 7 species, District-Manggoapi obtained Warmare Prafi SP-3 Masni SP-5 SP-8 species. highest colonization rate (94%) found roots (L.) originating composition consisting Acaulospora cf. rehmi, spinosa, gerdemanii, Glomus clarum, Gigaspora margarita, rosea, gigantea.
