The use of microorganisms to improve the availability of nutrients to plants is of great importance to agriculture. This study aimed to evaluate the effect of triple inoculation of cowpea with arbuscular mycorrhizal fungi (AMF), plant growth-promoting bacteria (PGPB) and rhizobia to maximize biological nitrogen fixation (BNF) and promote plant growth.

The polymerase chain reaction coupled with restriction fragment length polymorphism analysis (PCR/RFLP) was applied to distinguish arbuscular mycorrhizal fungi (AMF) species from an impacted semiarid soil. The ITS1-5.8S-ITS2 region was amplified with the primers ITS1 and ITS4 and the products of amplification were digested with the restriction enzymes(More)
The work was carried out to investigate the effects of different concentrations of NaCl on Brachiaria humidicola Rendle in the presence and absence of Glomus etunicatum Becker and Gerdemann, as well as to evaluate some growth parameters and the accumulation of free proline in the plant leaves. The soil used was a Neosoil Fluvic Eutrophic with pH of 6.5,(More)
The genetic variety of the Rhizobium isolates from acid and alkaline soils in the semiarid zone of Pernambuco state was evaluated through the use of 17 primers of arbitrary sequence. Amplified products were separated by electrophoresis in agarose gel at 1.4% and visualized by ethidium bromide coloration. The results obtained suggest a high genetic variety(More)
