Abstract
The influence of vesicular-arbuscular mycorrhiza (VAM) fungi inoculation on growth performance of Senna spectabilis was studied in a screen house experiment. The results obtained indicated the dependence of Senna spectabilis on mycorhizal symbiosis. Inoculation with vesicular-arbuscular mycorrhiza significantly improved the growth performance of Senna spectabilis. The height growth increased significantly by 85% after only three months while the root collar diameter increased by 71%. Shoot production increased by 213% while root biomass increased by 241%. Inoculation with vesicular-arbuscular mycorrhiza increased plant tissue phosphorus, nitrogen and potassium content. The better growth response of mycorrhizal plants were attributed to improvement in nutrient uptake, especially phosphorous, nitrogen and potassium. Vesiculararbuscular mycorrhiza inoculation has a high potential in agroforestry as a bio-fertilizer.
