Abstract

The mycorrhizosphere is the zone of soil influenced by roots colonized by mycorrhizal fungi and contains many microorganisms. This study aims to analyze mycorrhizal and bacterial populations in the mycorrhizosphere of mahogany (Swietenia macrophylla King.) seedlings growing in silica sand post-mining media by using organic pot as container growth media. The experimental design used was a Completely Randomized Design (CRD) consisting of two treatments, namely the composition and size of organic pot materials. The results showed that the composition of the organic pot could affect the presence of AMF spores. The organic pots composition of 50% newspaper, 35% compost, and 15% cocopeat showed the best results for the development of AMF spores and bacterial colonies, the development of AMF spores and bacterial colony populations in growing media was better than the development of AMF spores and bacterial colonies in organic pots. There are seven different morphological characters of bacterial colonies which are dominated by round, thready, flat, and white.
