Resumo: Intensive corn farming quickly depletes soil organic matter in the nutrient-poor soils of the Brazilian semiarid region. Application of vermicompost, an excellent organic fertilizer, could help solve that problem. This study evaluated the effect of applying Eisenia fetida vermicompost in the seeding furrows, at 0, 2, 4, 6, 8, and 10 Mg.ha-1 application rates, on the green ear yield and grain yield of two corn cultivars. Treatments were replicated five times with split-plots (vermicompost application rates within plots) in a completely randomized block design. The number of mature ears, number of kernels per ear (cultivar BR 106), and 100-kernel weight (cultivar AG 1051) were not affected by vermicompost application rate. However, vermicompost application increased total number and weight of unhusked and husked marketable green ears as well as grain yield. Total number of green ears was higher in cultivar BR 106 than in cultivar AG 1051. Conversely, grain yield and total ear weight and marketable weight of unhusked and husked green ears was higher in cultivar AG 1051, but responses in the latter two traits were dose-dependent.

A aplicação de vermicompostos, considerados excelentes adubos orgânicos, poderia contribuir para a solução desse problema. O objetivo do presente trabalho foi avaliar os efeitos da aplicação, nos sulcos de semeadura, de doses (0, 2, 4, 6, 8 e 10 Mg ha-1) de vermicomposto de Eisenia fetida, obtido a partir de esterco bovino, sobre os rendimentos de espigas verdes e de grãos de cultivares de milho (AG 1051 e BR 106). Utilizou-se o delineamento de blocos ao acaso com cinco repetições e parcelas subdivididas (vermicomposto nas parcelas). A aplicação de doses de vermicomposto não influenciou o número de espigas maduras, número de grãos espiga-1 (na cultivar BR 106) e massa de 100 grãos (na cultivar AG 1051). Mas a aplicação do vermicomposto aumentou os números e as massas de espigas verdes, totais e comercializáveis, empalhadas e despalhadas, e o rendimento de grãos. A cultivar BR 106 foi superior à cultivar AG 1051 quanto ao número total de espigas verdes. O inverso ocorreu nas massas total e de espigas verdes comercializáveis, empalhadas e despalhadas, e no rendimento de grãos. Mas nessas duas últimas características a superioridade da cultivar AG 1051, dependeu da dose do adubo.Universidade Federal Rural do Semi-Árido2017-03-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/467510.1590/1983-21252017v30n302rcREVISTA CAATINGA; Vol. 30 No. 3 (2017); 551-558Revista Caatinga; v. 30 n. 3 (2017); 551-5581983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/4675/pdfSilva, Paulo Sérgio Lima eSilva, Paulo Igor Barbosa eOliveira, Vianney Reinaldo deOliveira, Fábio Henrique Tavares deCosta, Lucas Ramos dainfo:eu-repo/semantics/openAccess2023-07-20T11:10:16Zoai:ojs.periodicos.ufersa.edu.br:article/4675Revistahttps://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:2024-04-29T09:46:18.235409Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
