In order to study the effect of Plant Growth Promoting Bacteria and Mycorrhizae Fungi application as seed coinoculation on three late maturity maize single cross hybrids seed germinability and seedling vigour a laboratory research conducted. 

Experiment conducted as 18 treatments (3 single crosses × 6 seed inoculations) two factorial based on complet randomized blocks design by four rplications. Studied Plant Growth Promoting Bacteria were Azotobacter chroococcum, Azospirillum lipoferum, Azospirillum brasilence and Pseudomonas fluorescens and studied arbascular mycorrhizae fungi were Funneliformis mosseae and Simiglomus hoi. Also studied late maturity maize single cross hybrids were SC700, SC704 and a new promising late maturity maize single cross hybrid B73×K18. Effect of coinoculation of seeds by studied Plant Growth Promoting Bacteria and Mycorrhizae Fungi on germination ability and seedling vigour of studied late maturity maize single cross hybrids evaluated by germinability, mean germination time, coefficient of velocity of germination, mean daily germination, daily germination speed, seedling length, primary shoot length, primary root length, seedling dry weight, primary shoot dry weight, primary root dry weight and  seedling vigour Index measurement.  

The results revealed that except of mean daily germination and coefficient of velocity of germination, other studied traits affected by intractions of hybrids and coinoculation. Likewise,  revealed that application of an inoculant of  three bacteria combination and Glomus mossae have highest growth promoting effect on germinability and traits related to seedling vigour of all hybrieds and Azotobacter chroococcum and Azotobacter chroococcum+ Pseudomonas fluorescens and Glomus mossae seed co inoculation by those bacteria  have most growth promoting effect respectively. Also, revealed that studied characters of SC704 more than other hybrids affected by growth promoting effect of studied bacteria and mycorhizae and respectively B73×K18 and SC700 affected by studied Plant Growth Promoting Rhizobacteria and mycorhizae fungi stimulating effect and studied characters have high correlation among them. 

Based on this research results application of studied Plant Growth Promoting Rhizobacteria and mycorhizae fungi as seed coinoculation had considerable effect on studied late maturity maize single cross hybrids seed germination enhancement and seedling improvement. Therefore, application of them as commercial biofertilizer maybe possible through seed coating for maize cultivation development.
