Soil and climatic conditions determine the rhizobia in association with Phaseolus vulgaris in southern Brazil.

ABSTRACT: The common bean (Phaseolus vulgaris L.) plays a significant economic and social role in Brazil. However, the national average yield remains relatively low, largely because most bean cultivation is undertaken by small-scale farmers. In this context, biological nitrogen fixation (BNF) is an effective strategy for improving crop yield. Therefore, it is important to identify novel rhizobial strains well suited to local climatic conditions. This study used Phaseolus vulgaris as a trap plant in soils from three distinct conservation areas (Ponta Grossa, Ortigueira, and Londrina) within Paraná State, Brazil. The soil chemical analysis revealed that the pH values in the Ponta Grossa and Ortigueira regions were low, whereas the Ortigueira region exhibited elevated aluminum levels. A total of 94 str
