Experiments were conducted at the Agricultural Research Center in Aleppo on the date of 2020, the effectiveness of these isolates was tested in fixing atmospheric nitrogen by inoculating them on nitrogen-free liquid environments, with a witness that was not inoculated with bacteria. The results showed the superiority of three isolates with atmospheric nitrogen fixation, where the percentage of atmospheric nitrogen fixation for the sixth, fourth and third three isolates, respectively, reached (12.4) (8.7) (6.2) mg N\/g, while the characterization results showed that the sixth bacteria is <em>Azospirillum brasilense<\/em>, and the fourth <em>is Azospirillum lipoferum<\/em>, the third is <em>Azospirillum amazonense.<\/em><\/span><\/p>\n<p><span style=\"font-family: 'Times New Roman', Times; font-size: 17px;\"><strong>Key words:<\/strong> nitrogen-fixing bacteria, Azospirillum, intimate soil, nitrogen.<\/span><\/p>\n<p><span style=\"font-family: 'Times New Roman', Times; font-size: 17px;\"><strong>Full paper in Arabic: <a href=\"http:\/\/agri-research-journal.net\/SjarEn\/wp-content\/uploads\/v10n4p22.pdf\">pdf<\/a><\/strong><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ghufran Hujaira* (1), Omiema Nasser (1), and Nabila Kreidi (2) (1).
