Resumo: | Sweet potato-bioethanol yield was evaluated in response to potassium fertilizer application. Experiments were performed using a 5 × 2 factorial design in which factors included the amount of K2O applied to the soil, with five levels (0, 30, 60, 120, and 240 kg ha-1) and genotype, with two levels (industrial genotype BDGPI #25 and table genotype BDGPM #04). Root yield, root starch and soluble solid contents, bioethanol yield, and economic viability of potassium application for bioethanol production were evaluated. Potassium affected root yield of both genotypes, with the highest yield observed at 140 kg K2O ha-1. Root starch concentration at harvest depended on genotype potential rather than potassium dose. Soluble solid content in fresh roots was lower than that in cooked roots, in which case, maximum conversion efficiency was observed at 109,69 and at 123.75 kg K2O ha-1 for BDGPM#04 and BDGPI#25, respectively. Bioethanol yield reached 10,484 and 9,839 L ha-1 at 151.87 and 136 kg K2O ha-1 for BDGPI#25 and BDGPM#04, respectively. Genotype BDGPI#25 was more efficient than sugarcane in converting potassium to bioethanol at 151.87 kg K2O ha-1, producing 10,484.29 L of bioethanol. In turn, BGDPM#04 showed maximum conversion efficiency relative to sugarcane at 122 kg K2O ha-1. |

Experimentos foram conduzidos em esquema fatorial 5 x 2. O primeiro fator foram 5 doses de potássio aplicado via solo na forma de K2O (0, 30, 60, 120 e 240 kg ha-1 de K2O) e dois genótipos de batata-doce: BDGPI#25 para industria e BDGPM#04 para mesa. Foi avaliado a produtividade de raízes de batata-doce, teor de amido nas raízes, sólidos solúveis, produtividade de bioetanol e viabilidade econômica da aplicação de potássio para produção de bioetanol. O potássio afeta a produtividade de raízes dos genótipos com maior rendimento na dose de 140 kg ha-1 de K2O. A concentração final de amido nas raízes de batata-doce depende do potencial de expressão do genótipo do que da dose de potássio. O teor de sólidos solúvel nas raízes crua é menor do que nas raízes cozidas. Nas raízes cozidas, os pontos de máxima eficiência foi de 109,69 kg ha-1 K2O no genótipo BDGPM#04 e 123,75 kg ha-1 K2O no genótipo BDGPI#25. A produtividade de bioetanol foi de 10.484 L ha-1 na dose de 151,87 kg ha-1 no genótipo BDGPI#25 e 9.839 L ha-1 na dose de 136 kg ha-1 K2O no genótipo BDGPM#04. O genótipo BDGPI#25 foi mais eficiente na conversão de potássio do que a cana-de-açúcar na dose de 151,87 kg ha-1 de potássio produzindo 10.484,29 L de bioetanol. Já o genótipo BDGPM#04 comparado com a cana-de-açúcar teve efeito máximo na dose de 122 kg ha-1.Universidade Federal de Uberlândia2024-01-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/6293310.14393/BJ-v40n0a2024-62933Bioscience Journal ; Vol. 40 (2024): Continuous Publication; e40002Bioscience Journal ; v. 40 (2024): Continuous Publication; e400021981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/62933/37803Brasil; Contemporary Copyright (c) 2024 Renato Sales Coeho, Ildon Rodrigues do Nascimento, João Francisco de Matos Neto, Márcio Antônio da Silveira, Valéria Gomes Momenté, Ádila Pereira de Sousahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCoelho, Renato SalesNascimento, Ildon Rodrigues do Neto, João Francisco de Matos Silveira, Márcio Antônio da Momenté, Valéria GomesSousa, Ádila Pereira de2024-04-03T20:47:42Zoai:ojs.www.seer.ufu.br:article/62933Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2024-04-03T20:47:42Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
