| This research focused on evaluating the usefulness of an arbuscular mycorrhizal fungus (Glomus intraradices) and a plant growth-promoting rhizobacterium (Pseudomonas fluorescens) to maize growth under water deficit stress. Field experiment was conducted at Soil and water research institute, Karaj Station, Iran, during 2006 growing season. Biological positive effects of the micro organisms on plant growth, nutrient uptake, grain yield and yield components in maize plants was recorded in the treatment receiving mixed inoculums of G. intraradices and P. fluorescens. Maize shoot P content, grain yield, yield components, harvest index, grain N and P, soil available P, root colonization percentage and water use efficiency increased significantly with the G.... |
