Abstract: A field experiment was conducted in the two summer successive seasons 2012and 2013 at Sahl- El-Tainia (North Sinia)to study the effect of foliar application Humic and Ascorbic acids and Azospirllim brasilense fertilizer on yield components, germination , seedling vigor and chemical analysis of maize grains. The two acids were applied according to factory recommendation (1.5 and 3.0 g per/ lit) seeds were inoculation with Azospirllim brasilense (200g/1kg seeds) before planting. The experimental design was randomized completely block design with three replications. The maize (Zea mays L) cultivar Triple hybrid 310 was used. The results showed that yield components , germination percentage ,shoot length, seedling fresh weight were increased under the application ascorbic acid 1.5g/l + Azospirllim brasilense, while the increase in radical length of seedling was under the application of humic acid 3.0g/l + Azospirllim brasilense. High reduction in accelerated ageing germination %, protein percentage in seeds were increased under ascorbic acid 1.5g/l and humic acid 1.5g/l with Azospirllim brasilense and seed oil percentage increased under ascorbic acid 1.5g/l with Azospirlliu brasilense .It was found the foliar application of ascorbic and humic acid combined with bio fertilizer increased macro- micronutrients concentration in maize grains compared with bio-fertilizer alone or control. From previous results we could recommend that the utilization of organic acids(ascorbic and humic acids combined with Azospirllim brasilense NO40 containing PGPR group) which gave the best results and improve of maize cultivar triple hybrid 310 productivity and quality under saline soil conditions in the North Sinai .
