An orthogonal experimental design L₉ (3⁴) with 10 repetitions was used to investigate the effect of Glomus claroideum (0, 1 or 2g⁻¹ plant), G. fasciculatum (0, 1 or 2g plant⁻¹), native diazotrophic bacteria (0, 10³ and 10⁵ UFC ml⁻¹) and sheep manure vermicompost (0%, 5% and 10% v/v) on maize plant growth, N and P in leaves and mycorrhization percent. Vermicompost explained most of the variation found for leaf number, wet weight, stem height, and diameter. Both mycorrhizas increased the plant wet weight but G. fasciculatum the most. Mycorrhization increased the P content, but not the N content. Mycorrhizal colonization increased when diazotrophic bacteria and vermicompost were added. It was found that weight of maize plants cultivated in peat moss amended with vermicompost increased when supplemented with G. fasciculatum and diazotrophic bacteria.
