【 摘 要 】

The aim of the present work was to evaluate the inoculation effects of Azospirillum sp. RAM-7 strain, in seeds of wheat, barley and oats cultures on yield and total nitrogen content of the grains in greenhouse experiments. Seeds inoculation with Azospirillum sp. RAM-7 strain enhanced grain yields, even so, the responses vary among the evaluated cultures. For wheat, significant increases were obtained when the inoculation was associated to 100% of the recommended nitrogen, although the treatment that received only inoculation produced 7.4% above the control, however this difference wasn't significant. For barley, the presence of the inoculant substituted 20% the recommended nitrogen fertilization. For oats the inoculation with Azospirillum sp. RAM-7 didn't provide a significant increase in grain yields. In relation to the total nitrogen content of the grains, for all studied cultures, significant differences were not observed among the evaluated treatments (p < 0.05).
