Abstract: Beneficial soil micro-organisms are essential in crop production for positive influence on soil fertility and for a friendly ecological association. In line with this, a factorial pot experiment of A 2×3 completely randomised design (RCD) and replicated three times was conducted at the Department af Agronomy, University of Ibadan, Oyo state in Nigeria. The factors involved in the experiment are: two levels of Arbuscular mycorrhiza (Glomus mossae) inoculation (with and without inoculation) and three early maturing cultivars of maize, ACR 9922.DMRSR, ACR.9928. DMRSR and ACR99. 31. DMRSR. The experiment was set up in 2006 and lasted for twelve weeks. The results showed differences in the response of the maize cultivars to the influence of mycorrhiza inoculation. The response of cultivar ACR. 9931.DMRSR vegetative performance MAS Sİgnificantly reduced (Pr<0.05) at 2, 5 and 7 weeks after sowing (WAS); showing that there were competition advantage of mycorrhiza inoculation from 2 to 7 WAS. The grain yield under mycorrhiza inoculation followed a pattern: A CR. 9922. DMRSR> ACR. 9928. DMRSR>ACR. 9931. DMRSR, with grain yields of 37.5, 1 7.6 and 12.7g, respectively. Under non-inoculation of mycorrhiza (without) the pattern was ACR 9928. DMRSR> ACR.9922. DMRSR >ACR. 9931. DMRSR with grain yields of 48.6, 28.6 and 7. 6g, respectively. It can be deduced, therefore, that the association between the three maize cultivars and Arbuscular mycorrhiza positively influenced the vegetative and grain yield of these maize cultivars. The study concluded that maize cultivar ACR. 9922. DMRSR and ACR. 9928. DMRSR are promising cultivars of higher yield suitable for nutrient-depleted soil if mycorrhizal association is encouraged.
