INFLUENCE OF MYCORRHIZA ON SELECTED TREE SPECIES: Gliricidia sepium, Acacia auriculiformis, Leucaena leucocephala
ABSTRACT
The influence of mycorrhiza fungi inoculation on growth performance of Gliricidia sepium, Acacia auriculiformis, and Leucaena leucocephala was studied in a nursery experiment. The results obtained indicated the dependence of Gliricidia sepium, Acacia auriculiformis, and Leucaena leucocephala on mycorhizal symbiosis. Inoculation with mycorrhiza significantly improved the growth performance of Gliricidia sepium, Acacia auriculiformis, and Leucaena leucocephala. The height growth increased significantly by 65% after only three months while the nodulation and rootability increased by 70% and 50% respectively. Inoculation with mycorrhiza did not however cause an increase in nitrogen concentration in the plant tissues (stem, root and leaves).
