Resumo: | The objective of this work was to assess the agronomic performance of cowpea cultivars depending on sowing seasons in the Cerrado biome. Thus, an experiment was conducted in Uberaba, State of Minas Gerais, Brazil, in a complete randomized block design, in a 6x3 factorial arrangement, using six cowpea cultivars (BRS-Itaim, BRS-Guariba, BRS-Potengi, BRS-Cauamé, BRS-Novaera and BRS-Tumucumaque) and three sowing seasons (Dec 14, 2012; Jan 14, 2013; and Feb 14, 2013), with four replications. The interaction between the cultivars and sowing seasons was assessed regarding the number of days for full flowering, number of days for pod maturation, number of trifoliate leaves, height of the first pod-bearing node, pod length, number of pods per plant, final plant population, 100-grain weight and grain yield. The cowpea cultivars sown in December produced the lowest numbers of pods per plant and grains per pod, resulting in the lowest grain yields. The cultivar BRS-Tumucumaque had the highest grain yield in the January sowing. The highest grain yields were found in the February sowing, especially when the cultivars BRS-Itaim (3,439 kg ha-1), BRS-Novaera (3,435 kg ha-1), BRS-Guariba (3,168 kg ha-1) and BRS-Potengi (3,107 kg ha-1) was used. |

O experimento foi conduzido em Uberaba-MG, no delineamento de blocos casualizados, em arranjo fatorial 6 x 3, correspondendo a seis cultivares de feijão-caupi (BRS Itaim, BRS Guariba, BRS Potengi, BRS Cauamé, BRS Novaera e BRS Tumucumaque) e três épocas de semeadura (14/dez/2012 - E1, 14/jan/2013 - E2 e 14/fev/2013 - E3), com quatro repetições. Verificou-se interação cultivares x épocas de semeadura para o número de dias para o florescimento pleno, dias para a maturação das vagens, número de trifólios, altura de inserção da primeira vagem, comprimento de vagens, número de vagem por planta, população final de plantas, massa de 100 grãos e produtividade de grãos. Quando semeadas em dezembro, as cultivares de feijão- caupi produziram menor número de vagens por planta e de grãos por vagem, resultando em inferior produtividade de grãos. A cultivar BRS Tumucumaque apresentou maior produtividade de grãos quando semeada em janeiro. Produtividades de grãos superiores são obtidas na semeadura de fevereiro, sobressaindo-se as cultivares BRS Itaim, BRS Novaera, BRS Guariba e BRS Potengi, com 3.439, 3.435, 3.168 e 3.107 kg ha-1, respectivamente.Universidade Federal Rural do Semi-Árido2017-01-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/518410.1590/1983-21252017v30n211rcREVISTA CAATINGA; Vol. 30 No. 2 (2017); 361-369Revista Caatinga; v. 30 n. 2 (2017); 361-3691983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/5184/pdfAlmeida, Fernando da SilvaMingotte, Fábio Luis ChecchioLemos, Leandro BorgesSantana, Márcio José deinfo:eu-repo/semantics/openAccess2023-07-20T10:54:05Zoai:ojs.periodicos.ufersa.edu.br:article/5184Revistahttps://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:2024-04-29T09:46:21.346013Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
