Abstract

Nitrogen fixation by efficient native rhizobia strains may contribute to increase grain yield and to promote economy of nitrogen fertilizers in Brazilian semi-arid region. A greenhouse experiment was carried out in order to evaluate the nitrogen fixation efficiency of four peanut genotypes inoculated with rhizobia isolated from northeastern Brazil. The IAC Tatu cultivar established the most efficient symbiosis, while BR1 depended of N fertilizers application and showed high levels of total N in shoots only with S11 isolate. The majority of the rhizobia isolates established efficient symbiosis and N accumulation with IAC Tatu, Sertão and Embrapa 142-L7 genotypes, when compared to N mineral treatment. The results showed that native rhizobia can promote good nodulation, total N and dry matter yield, and may be used as specific inoculant for peanut in soils of Brazilian semi-arid region.
