Resumo: | The interaction of cowpea with efficient strains of rhizobia in biological nitrogen fixation can allow increased yield, which can completely replace nitrogen fertilization and can reduce production costs. The aim of this study was to evaluate the response of cowpea cultivar BRS Guariba to inoculation with six strains of rhizobia (UFLA 03-164, UFLA 03-154, INPA 03-11B, UFLA 03-84, BR 3267 and BR 3262) in a field experiment conducted in the Southwest of Piauí. The experimental design was randomized blocks with eight treatments and four replicates, including the six cited strains and two uninoculated controls, one with mineral nitrogen (70 kg ha-1) and the other without mineral nitrogen. Nodulation, growth, yield, nitrogen accumulation in shoots and in grains and crude protein content in grains were evaluated. Strains under selection (UFLA 03-154 and UFLA 03-164) promoted yields that were higher compared to those obtained by strains authorized as inoculants (INPA 03-11B, BR 3267 and BR 3262). Inoculation with strains UFLA 03-84, UFLA 03-154 and UFLA 03-164 promoted yields equivalent to the control with mineral nitrogen (796.51 kg ha-1) and similar to the yield obtained with the control without mineral nitrogen and without inoculation, indicating efficient symbiosis of the indigenous rhizobia. UFLA 03-154 was better than the other treatments in terms of increased crude protein. |

Objetivou-se avaliar a resposta do feijão-caupi cultivar BRS Guariba à inoculação com seis estirpes de rizóbio (UFLA 03-164, UFLA 03-154, INPA 03-11B, UFLA 03-84, BR 3267 e BR 3262) em experimento conduzido em campo no Sudoeste do Piauí. O delineamento experimental foi em blocos casualizados com oito tratamentos e quatro repetições, sendo as seis estirpes citadas e dois controles não inoculados, um com nitrogênio mineral (70 kg ha-1) e outro sem nitrogênio mineral. Foram avaliados nodulação, crescimento, produtividade, acúmulo de nitrogênio na parte aérea e nos grãos e o teor de proteína bruta nos grãos. As estirpes em fase de seleção (UFLA 03-154 e UFLA 03-164) promoveram rendimento de grãos superiores aos obtidos pelas estirpes autorizadas como inoculantes (INPA 03-11B, BR 3267 e BR 3262). As inoculações com as estirpes UFLA 03-84, UFLA 03-154 e UFLA 03-164 proporcionam rendimento de grãos equivalentes ao controle com nitrogênio mineral (796,51 kg ha-1), porém, semelhantes ao rendimento obtido com o controle sem nitrogênio mineral e sem inoculação, indicando boa eficiência simbiótica das populações nativas de rizóbio. A UFLA 03-154 destacou-se dos demais tratamentos com relação ao aumento de proteína bruta.Universidade Estadual de Londrina2018-03-19T16:28:03Z2018-03-19T16:28:03Z2014-11info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfCOSTA, E.
