Abstract

The utilization of single arbuscular mycorrhizal fungi (AMF) is constrained by the propagation of the single spore and usually depends on the host plant. This study aims to examine the effectiveness of single culture propagation of several genera of AMF from the rhizosphere of cocoa and the concentration of NPK on the host Pueraria javanica. The study was designed with a completely randomized design with two factors. The first factor was the genus FMA which consisted of Acaulospora sp1 (M1), Acaolospora sp2 (M2), Glomos sp1 (M3), Glomous sp2 (M4), Glomous sp 3 (M5). The second factor was that the concentration of liquid fertilizer was five levels: control (P0), 0.5g/l water (P1), 1g/l water (P2), 1.5g/l water (P3), 2g/l water (P4), and repeated four times. Parameters observed: root infection, spore number, main stem length, root length. The study showed that the highest number of spores resulted from the interaction of Acauspora sp.1 with 0.5 g/l NPK. The most extended stem and root lengths were produced at 1 g/l NPK with Acauspora sp 2, 27.40 cm, and 2 g NPK fertilizer with Acauspora sp.2, which had a root length of 8.8 cm. The highest colonization rate was found in plants not given NPK and infected with Glomous sp.1. This study showed that Pueraria javanicum was effective as a host plant for developing AMF in a single culture.
