Conteúdo: 	We report studies on the possible effects of fertilisation with high level of N (300 kg of N ha-l ) on the occurrence and numbers of the diazotrophic bacteria Herbaspirillum spp. and Acetobacter diazotrophicus in sugar cane plants. In the sugar cane genotype SP79-2312, the N fertilised plants generally showed higher concentrations of this element. These same plants also had lower numbers of A. diazotrophicus, while the population of Herbaspirillum spp. was not affected by N application. These differences in the concentration of N and the numbers of A. diazotrophicus due to N application were not shown in the variety SP70-1143. The numbers of A. diazotrophicus were also shown to be influenced by the harvest time, becoming reduced in the harvests that coincided with dry periods of the year.
