Abstract

This research provides a better understanding of the various types of Arbuscular Mycorrhizal Fungi (AMF) associated with agroforestry pattern rubber plantations. By knowing these types, the most suitable AMF species can be processed and selected to increase the productivity of rubber plants. This study aims to explore, identify, and inventory AMF in the rhizosphere of rubber plantations in agroforestry patterns. This research was conducted in March 2023. Soil sampling was carried out in Jojjolo Village, Ballasaraja Village, Bulukumpa District, Bulukumba Regency. Sampling of soil and roots using the method International Centre Research in Agroforestry (ICRAF). Then for the extraction of spores using the wet filter pouring technique and centrifugation technique. The filter results that have been transferred to the petri dish. Spores were observed and counted under a dissecting microscope with 4x magnification. Then transfer the spores based on their morphotype onto filter paper with vertical and horizontal lines in a 0.5 cm x 0.5 cm cup to facilitate observation. The results showed 9 spore morphotypes at 3 density levels. Among them, at rare densities, 954 spores were found with an average of 64 spores per plot. Then at medium density, 952 spores were obtained with an average of 63 spores per plot, and at a dense density, 766 spores were obtained with an average of 51 spores per plot.
