Resumo: The objective of this study was to evaluate the symbiotic efficiency of three novel nitrogen-fixing bacterial strains with cowpea cv. BRS Guariba as forage. Two experiments were carried out in the field in Balsas and São Raimundo das Mangabeiras, MA, in a randomized block design with seven treatments and four replications: three novel strains efficient in symbiotic nitrogen fixation with cowpea (UFLA 3 -153, UFLA 3-154 and UFLA 3-164), two strains already approved as inoculants by MAPA (UFLA 3-84/SEMIA 6461 and INPA 3-11B/SEMIA 6462), and two controls without inoculation, with and without mineral N. Symbiotic efficiency of strains was determined by the number of nodules, nodules dry matter, shoot dry matter, relative efficiency, crude protein content and shoot N content. Strains UFLA 3-154 and UFLA 3-164 were the most efficient in Balsas, whereas UFLA 3-153 and UFLA 3-164 were the most efficient in São Raimundo das Mangabeiras. Strains UFLA 3-153, UFLA 3-154 and UFLA 3-164 were more efficient in symbiotic nitrogen fixation with cowpea than the strains already approved as inoculants UFLA 3-84 and INPA 3-11B in the climatic and edaphic conditions of southern Maranhão. UFLA 3-164 is the most efficient strain in this region.

BRS Guariba como forrageira. Foram conduzidos dois experimentos em campo, em Balsas e São Raimundo das Mangabeiras, MA, em delineamento em blocos casualizados com sete tratamentos e quatro repetições, sendo: três novas estirpes eficientes em feijão-caupi (UFLA 3-153, UFLA 3-154 e UFLA 3-164), duas estirpes já aprovadas como inoculantes pelo MAPA (UFLA 3-84/SEMIA 6461 e INPA 3-11B/SEMIA 6462) e dois controles sem inoculação, com e sem N mineral. A eficiência simbiótica das estirpes foi determinada pelo número e massa seca de nódulos, produção de matéria seca da parte aérea, eficiência relativa, teor e acúmulo de proteína bruta e nitrogênio na parte aérea. As estirpes UFLA 03 -154 e UFLA 3-164 destacaram-se na eficiência simbiótica de N2 em Balsas e a UFLA 3-153 e UFLA 3-164 em São Raimundo das Mangabeiras. As estirpes UFLA 3-153, UFLA 3-154 e UFLA 3-164 são mais eficientes em fixar nitrogênio do que as estirpes aprovadas como inoculantes UFLA 3-84 e INPA 3-11B nas condições edafoclimáticas do sul do Maranhão. A UFLA 3-164 é a estirpe mais eficiente em fixar nitrogênio na região estudada.Universidade Federal Rural do Semi-Árido2018-08-31T10:29:24Z2018-08-31T10:29:24Z2016-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfFARIAS, T.
