Application of biofertilizers, especially plant growth promoting rhizobacteria (PGPR) through integrating use by chemichal fertilizers is most important strategy for integrated plant nutrition in sustainable management of agroecosystems and their production increase by Adequate Input Sustainable Agriculture (AISA) system. In order to study the effect of Azotobacter chroococcum, Azospirillum brasilense As. lipoferum and Pseudomonas fluorescens application on late maturity maize (Zea mays L.) single cross hybrids (SC700, SC 704 and a promising single cross B73K18) silage fodder yield a factorial field experiment was conducted. Hybrids seeds single inoculated with one by one bacteria and coinoculated by two and four bacterial combined inoculants and no inoculation as control treatment. In grain milky stage, Plants harvested and then silage fodder yield per hectare, plant fresh weight, dry weight (biomass) per hectare and per plant, plant leaf number and top of ear leaf number, plat height and stem diameter were determined. Results revealed that all studied traites affected by experimental treatments. Interactions of maize hybrids and plant growth promoting rhizobacteria for plant fresh weight and top of ear leaf number were significant (p0.05) and other studied traits highly significant (p0/01). Also this resultes cleared that silage fodder yield per hectare and other studied traits of SC704 when the seeds coinoculated by four bacteria were better than other hybrieds.
