In order to the optimization of biological nitrogen fixation (BNF) associated with cowpea in Cerrado areas in the Northeast region of Brazil , this work aimed to analyze the diversity of rhizobial populations in eight areas of Cerrado, during a soybeam and rice-cowpea rotation . morphological traits (mucous productions and colony morphology), genotypic analyzes (ARDRA 16S) and intrinsic resistance to antibiotics were determined for a collection of isolates captured using cowpea as host-plant. The morphological data showed a inverse correlation (p> 0.05) bettween the number of legume (soybean and cowpea) crops, according to the history of each area, and rhizobium diversity, estimated by the Shannon-Weaver index. ARDRA data showed that native Cerrado... |

Nodulating bacteria from the famaly Rhizobiaceae are common in the semi-arid tropics around the world. The brazilian semi-arid region extends over 95 million hectares of which only 3% is suitable for irrigation, therefore leaving an immense dryland area to be exploited by peasant farmers, who often lack appropriate technologies for sustainable management. Cowpea is an impoertant crop in this area, representing the staple protein source for human nutrition. This work aimed to identify rhizobial strains capable of guaranteeint sufficient nitrogen derived from biological fixation fpr cowpea cultivated in dryland areas, evaluating not just efficiecy but also the ecological parameters of competitiveness and survival in the soil. Grain yield and nodulation... |
