Abstract

The effects of arbuscular mycorrhizal (AM) inoculation – Acaulospora muricata – and Araxá rock phosphate levels (0, 100 and 200 kg of P2O5/ha), on dry matter (DM) yield, and nitrogen and phosphorus uptake of Andropogon gayanus cv. Planaltina, were evaluated in a glasshouse trial, utilizing a Yellow Latosol (Oxisol), clayey, previously sterilized. The AM inoculation, alone or combined with rock phosphate fertilization, promoted an increments on DM yields and nitrogen and phosphorus uptake. However, there were significant effects of phosphorus levels. Rock phosphate fertilization improved the efficiency of response to AM inoculation, occurred a synergistic effect. The root colonization did not affected by rock phosphate fertilization.
