Abstract

Biological nitrogen fixation is of fundamental importance for agricultural sustainability, and the evaluation of the rhizobial diversity contributes to the knowledge of their diversity in collections, as well as for later use in agricultural systems. The objective of this paper was to evaluate phenotype diversity and symbiotic efficiency of rhizobia isolates from Amazonian soils when inoculated on cowpea (Vigna unguiculata L. Walp.). The native isolates presented diversity regarding their morphologic and physiological characteristics. It was verified that the inoculation with isolates of native rhizobia contributed to the increase of the biomass, nodulation on cowpea and symbiotic efficiency.
