Resumo: | This work aimed to evaluate the agronomic efficiency of cowpea cultivars inoculated with rhizobia strains recommended for cowpea in a semiarid environment. Experiments were carried out in Mossoró, Rio Grande do Norte, in two agricultural cycles: the first from January to April 2019, and the second from June to August of the same year. The experimental design adopted was randomized blocks with four replications arranged in a 4 × 4 x 2 factorial scheme, with treatments consisting of four cowpea cultivars: ‘BRS Imponente’, ‘BRS Itaim’, ‘BRS Novaera’, and ‘BRS Tumucumaque’ as well as three sources of N, two strains of Bradyrhizobium spp. registered for cowpea (BR 3262 and BR 3267) and, the application of mineral N (50 kg ha-1), beyond an absolute control, without inoculation or application of mineral N. In addition to two planting seasons. The cultivar ‘BRS Tumucumaque’ showed greater productive potential. The inoculation of cowpea seeds with Bradyrhizobium strains BR 3262 and BR 3267 provided grain yields similar to those obtained with the application of mineral N. |

Os experimentos foram conduzidos em Mossoró, Rio Grande do Norte, em duas safras agrícolas: o primeiro de janeiro a abril de 2019, e o segundo de junho a agosto do mesmo ano. O delineamento experimental adotado foi de blocos ao acaso com quatro repetições em esquema fatorial 4 × 4 x 2, com tratamentos constituídos por quatro cultivares de feijão-caupi: 'BRS Imponente', 'BRS Itaim', 'BRS Novaera' e 'BRS Tumucumaque' e três fontes de N, duas linhagens de Bradyrhizobium spp. registradas para o feijão-caupi (BR 3262 e BR 3267), aplicação de N mineral (50 kg ha-1), além de uma testemunha absoluta, sem inoculação ou aplicação de N mineral. Além de duas épocas de plantio. A cultivar 'BRS Tumucumaque' apresentou maior potencial produtivo. A inoculação de sementes de feijão-caupi com as linhagens de Bradyrhizobium BR 3262 e BR 3267 proporcionou rendimentos de grãos semelhantes aos obtidos com a aplicação de N mineral.Universidade Federal Rural do Semi-Árido2023-09-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1198410.1590/1983-21252023v36n406rcREVISTA CAATINGA; Vol. 36 No. 4 (2023); 785-793Revista Caatinga; v. 36 n. 4 (2023); 785-7931983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/11984/11320Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccessOliveira, Pedro Ramon Holanda deLopes, Welder de Araújo RangelSilveira, Flávio Pereira da MotaSantos, Manoel Galdino dosSantos, Gisele Lopes dosSilva, Silvana Fraga daSilveira, Lindomar Maria daBarros Júnior, Aurélio Paes2023-09-28T13:11:52Zoai:ojs.periodicos.ufersa.edu.br:article/11984Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:47:06.622814Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
