Performance of seedling and mixed-species planting test of three species of Rubiaceae treated by different seedling media and mycorrhizae application

Seedling growth in the nursery and early field performance of three fast-growing tree species from Rubiaceae family, i.e., white jabon ( Neolamarckia cadamba ), red macrophylla , gempol Nauclea orientalis were tested by using different seedling media arbuscular mycorrhizal fungi (AMF) treatments mixed-species tests. The experiment design test was laid out following a split-split plot randomized complete block with four replications. main factors species, sub-factors media, sub-sub consisted AMF inoculation, mixed planting pattern. White had more dominant both at level until age 2 years, followed jabon. inoculation those strongly influenced characteristics like high fertility levels resulting very low percentage colonization. In trial, all infected mycorrhizae colonization percentages ranging 27.6% to 57.7%, which suspected be an infection native site. application significant effect on diameter 2-year-olds increase 14.4% 8.4%, respectively.
