Abstract

The present experiment was aimed to evaluate the response of sugarcane varieties inoculated with endophytic diazotrophic bacteria. Sixteen sugarcane varieties were used for three kind of treatrnents (no inoculation and inoculation with 120 kg N/hectare). The inoculant was a mixture of five strains of bacterial species isolated from sugarcane. There were significant differences between genotypes (G) and genotype x treatment interaction (GxT) for ali the traits. The variety SP 71-6949, SP 78-4764 and RB 867515 were found responsive to biological nitrogen fixation and can be used in breeding programs which are directed to study and selection of promising genotypes responsible for the biological nitrogen fixation.
