Resumo: | Among the various forage species used in ruminant feeding, elephant grass (Pennisetum purpureum Schum.) is notable as it is a perennial plant and has a high potential for dry matter production. The present study evaluated the performance of elephant grass cultivars and soil chemical characteristics under different biochar addition levels and at different evaluation times under irrigation in the dry season. The treatments were arranged in a factorial randomized complete block design (CBD) and analyzed in a split-plot design according to cultivar (BRS Capiaçu and BRS Kurumi) x biochar dose (0, 8, 16 and 24 t ha-1); the subplots consisted of four evaluation times (71, 225, 335 and 447 days after application of biochar), with four replicates. The soil chemical characteristics were evaluated without inclusion of the time factor according to a CBD in a 2 x 4 factorial scheme, with 4 replications. The attributes analyzed were soil fertility, morphometry and elephant grass yield. The performance of the cultivars improved at 225 days (2nd evaluation) and 335 days (3rd evaluation) after biochar application. The biochar doses did not significantly increase morphometric attributes, cultivar productivity or soil fertility. The application of biochar did not improve the yield attributes or crude protein of elephant grass cultivars under the conditions of this study. |

Objetivou-se com o presente trabalho avaliar o desempenho de cultivares de capim elefante e características químicas do solo sob diferentes níveis de biochar e épocas de avaliação sob irrigação na época da seca. Os tratamentos foram dispostos em delineamento em blocos casualizados (DBC) em esquema fatorial, e analisado em parcelas subdivididas, sendo as parcelas, as cultivares BRS Capiaçu e BRS Kurumi x doses de biochar (0, 8, 16 e 24 t ha-1), e as subparcelas, quatro épocas de avaliação (71, 225, 335 e 447 dias após aplicação do biochar), com quatro repetições. Para avaliação de características químicas do solo o delineamento não teve o fator épocas, sendo analisado em DBC em fatorial 2 x 4, com 4 repetições. Os atributos analisados foram a fertilidade de solo, a morfometria e o rendimento de capim elefante. Nas avaliações aos 225 (2ª) e 335 (3ª) dias após aplicação de biochar houve melhor desempenho das cultivares. As doses de biochar não aumentaram significativamente atributos morfométricos, de produtividade das cultivares e fertilidade do solo. A aplicação de biochar não melhora os atributos de produtividade e proteína bruta das cultivares de capim elefante nas condições deste estudo.Universidade Federal Rural do Semi-Árido2023-12-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1178610.1590/1983-21252024v3711786rcREVISTA CAATINGA; Vol. 37 (2024); e11786Revista Caatinga; v. 37 (2024); e117861983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/11786/11403Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccessPacheco, Laiane BatistaMachado, Roriz LucianoSoares, Frederico Antonio LoureiroSilva, Pedro Santhyago Ferreira daRabelo, Kassia Cristina de CaldasLima, Ângelo Adão de2024-04-22T17:59:21Zoai:ojs.periodicos.ufersa.edu.br:article/11786Revistahttps://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:2024-04-29T09:47:05.412350Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
