Silva, Valéria Nogueira da; Silva, Luiz Eduardo de Souza Fernades da; Martínez, Cosme Rafael; Burity, Hélio Almeida; Figueiredo, Márcia do Vale BarretoThe effect of Paenibacillus and Bacillus (Plant Growth Promoting Rhizobacteria - PGPR) strains on the symbiosis of the caupi [Vigna unguiculataM (L.) Walp.] with Bradyrhizobium sp. was studied in vases of Leonard. The caupi cultivar used was IPA-205. The plants were irrigated with an N-Free nutrient solution. The inoculations with PGPR promoted a better growth of the root in relation to the co-inoculations, as ...
