Resumo: Splitting nitrogen (N) fertilizer application can be an efficient nutrient management technique to improve productivity and plant quality, as well as to reduce the negative environmental impact caused by N losses. In this context, the present study investigated how the management of N affects the agronomic characteristics of field-grown arugula plants. Nine treatments were assessed in a randomized complete block design, in a 4 x 2 + 1 factorial scheme, with three replicates. The evaluated factors were doses of N (60, 120, 180 and 240 kg N ha-1), split N fertilizer applications at side-dress (two and three times) and an additional treatment without a N supply. Maximum height was obtained with the application of 198 kg N ha-1. Nitrate content, fresh mass and productivity increased with increasing N doses. There was no effect of split N fertilizer applications on the characteristics evaluated. Therefore, the supply of 240 kg N ha-1 divided into two portions was considered as the best management strategy.

Foram avaliados nove tratamentos, em delineamento experimental de blocos ao acaso, em esquema fatorial 4 x 2 + 1, com três repetições. Os fatores avaliados foram doses de N (60, 120, 180 e 240 kg ha-1 de N),  parcelamento da adubação nitrogenada em cobertura (duas e três vezes) e um tratamento adicional sem a aplicação  de N. Máxima altura foi obtida com a aplicação de 198 kg ha-1 de N. O aumento das doses de N promoveu o aumento do teor de nitrato, da massa fresca e da produtividade da rúcula. Não houve efeito do parcelamento da adubação nitrogenada em cobertura nas características avaliadas. Assim, o fornecimento de 240 kg ha-1 de N, aplicado em duas parcelas foi considerado como o melhor manejo.  Universidade Federal Rural do Semi-Árido2021-09-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/993210.1590/1983-21252021v34n409rcREVISTA CAATINGA; Vol. 34 No. 4 (2021); 824-829Revista Caatinga; v. 34 n. 4 (2021); 824-8291983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/9932/10744Copyright (c) 2021 Revista Caatingainfo:eu-repo/semantics/openAccessNascimento, Camila SenoNascimento, Carolina SenoCecílio Filho, Arthur Bernardes2023-07-04T13:34:16Zoai:ojs.periodicos.ufersa.edu.br:article/9932Revistahttps://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:2024-04-29T09:46:54.166714Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
