The effects of inoculation with arbuscular mycorrhizal (AM) fungi, organic fertilizer (F) applications, and
soil sterilization on maize growth were evaluated in a pot experiment. The experiment was in a completely
randomized factorial design (2 x 4 x 2) with six replicates for each treatment. There were two soil
treatments (sterilized soil, SS and unsterilized soil, US), four organic fertilizer treatments (0.0, 0.5, 1.0 and
2.0 g kg1 soil), and two AM fungi treatments (inoculation with Glomus mosseae, +AM and uninoculated
control, AM). Inoculated plants generally had greater AM colonization, plant height, dry weight and
phosphorus (P) uptake than uninoculated controls, and these parameters were significantly increased
as the organic fertilizer application increased up to 0.5 g kg1 but decreased or had no significant effect
compared to the uninoculated plants at the highest fertilizer rate (2.0 g kg1). Plant growth, P uptake and
AM colonization of root system were significantly higher in sterilized soil compared to the unsterilized
control. Our results indicated that the inoculation of AM fungi in field soil with optimal organic fertilizer
application greatly improved maize growth and nutrient uptake, and the effect was greater under
sterilized soil condition.
