Rhizobias performance with rhizobacteria growth promoter in plants in the cowpea crop (Vigna unguiculata [L.] Walp.) - DOI: 10.4025/actasciagron.v28i3.964

Abstract

The aim of this work was to verify the cocolonization potential in cowpea bean (Vigna unguiculata [L.] Walp.) for Paenibacillus and Bradyrhizobium, using different inoculation methods to provide growth, seeking a maintainable agriculture. The study was carried out at Empresa Pernambucana de Pesquisa Agropecuária, in Yellow Argisol (Itapirema, Pernambuco State). Two methods of inoculation (seed and soil) in cowpea crop (IPA-205) was used. The following aspects were evaluated: number and dry matter nodule; shoot dry matter (SDM) and root (RDM); relation SDM/RDM; nitrogen accumulated in the SDM and plant height. The rhizobial strains showed low stability in the different inoculation methods. The symbiotic efficiency of the cocolonization for Paenibacillus and the Bradyrhizobium strains in the different inoculation methods were variable. Results showed that the benefits here are evident. And, this literature review can address future studies aiming to explain the behaviors mentioned above under different mechanisms of action of each bacterial cell.
