Resumo: | Poultry litter biochar has shown to be promising in crop development and production. On this basis, this study was developed to investigate the influence of increasing rates of poultry litter biochar on the growth and production of maize hybrid BRS 2022. The experiment was laid out in a completely randomized design with six biochar rates (0, 2.0, 4.0, 6.1, 8.1 and 10.1 t ha-1) and four replicates. Plots consisted of pots with a volume of 20 dm3, with one plant each. The following variables were evaluated at 83 days after sowing: plant height; first-ear insertion height; stem diameter; number of leaves; leaf area; internode length and number; stem, leaf and total dry weights; ear weight; grain weight per plant; 1000-grain weight; and ear length and diameter. Biochar application influenced plant height; first-ear insertion height; stem diameter; leaf area; internode length; and stem, leaf and total dry weights, having a positive impact in increasing in ear weight, grain weight per plant, 1000-grain weight and ear length and diameter. For the conditions in which the experiment was conducted, the recommended biochar rate to obtain the best results is 6.4 t ha-1. |

Dessa forma, o objetivo com esse trabalho foi o de avaliar a influência de doses crescentes de biocarvão de cama de aviário no crescimento e na produção do milho híbrido BRS 2022. O experimento foi conduzido em delineamento inteiramente casualizado, com quatro repetições, sendo seis doses de biocarvão (0; 2,0; 4,0; 6,1; 8,1 e 10,1 t ha-1) e as parcelas constituídas por uma planta por vaso com volume de 20 dm3. Aos 83 dias após a semeadura do milho foram avaliadas as seguintes variáveis: alturas da planta e da inserção da primeira espiga, diâmetro do colmo, número de folhas, área foliar, comprimento e número de internódios, fitomassa seca de colmos, de folhas e total, massa de espiga, de grãos por planta e de 1000 grãos e comprimento e diâmetro de espigas. A aplicação do biocarvão influenciou na altura da planta e da inserção da primeira espiga, diâmetro do colmo, área foliar, comprimento de internódios, fitomassa seca de colmo, de folhas e total, refletindo positivamente no aumento das massas de espiga, de grãos por planta, de 1000 grãos, comprimento e diâmetro de espigas. Para as condições em que o experimento foi conduzido a dose de biocarvão recomendada para obtenção dos melhores resultados é de 6,4 t ha-1.UEL2021-10-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa cientificaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4393910.5433/1679-0359.2021v42n6SUPL2p3707Semina: Ciências Agrárias; Vol. 42 No. 6SUPL2 (2021); 3707-3720Semina: Ciências Agrárias; v. 42 n. 6SUPL2 (2021); 3707-37201679-03591676-546Xreponame:Semina.
