Resumo: New hybrid onions that are more productive are currently being cultivated. Information on growth and nutrient accumulation must thus be updated to assist in the refinement of existing recommendations, enabling the better exploitation of the productive potential of these new genotypes. We determined the growth of plants and the accumulation and export of nutrients of the short-day onion ‘Soberana’ established by direct seeding. The experimental design was a randomized block with four replicates and the treatments were evaluation times. Leaf number, tissue dry weight, nutrient accumulation, and the maximum daily rate of accumulation were evaluated throughout the growing cycle. The order of nutrient accumulation was (g plant-1) K (0.72) > Ca (0.38) > N (0.32) > S (0.14) > P (0.08) > Mg (0.06) and (mg plant-1) Fe (2.26) > Mn (1.43) > Cu (0.93) > Zn (0.91) > B (0.85). Macronutrient demand was highest between 61 and 148 days after sowing (DAS), and micronutrient demand was highest between 70 and 148 DAS.

Assim, informações sobre o crescimento e absorção de nutrientes devem ser atualizadas para auxiliar no refinamento das recomendações existentes, possibilitando melhor explorar o potencial produtivo desses novos genótipos. Objetivou-se com o trabalho determinar o crescimento, acúmulo e exportação de nutrientes do híbrido de cebola Soberana no sistema de semeadura direta. O delineamento experimental foi o de blocos casualizados, com quatro repetições, onde os tratamentos foram épocas de avaliação. Avaliou-se o número de folhas, massa seca, acúmulo de nutrientes e a taxa máxima de acumulo diário. A sequência de acúmulo de nutrientes foi (g planta-1): K (0,72) > Ca (0,38) > N (0,32) > S (0,14) > P (0,08) > Mg (0,06) e (mg planta-1) Fe (2,26) > Mn (1,43) > Cu (0,93) > Zn (0,91) > B (0,85). A exigência máxima dos macronutrientes ocorreu entre 61 e 148 dias após a semeadura (DAS) e dos micronutrientes entre 70 e 148 DAS.Universidade Federal Rural do Semi-Árido2018-10-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/682110.1590/1983-21252018v31n427rcREVISTA CAATINGA; Vol. 31 No. 4 (2018); 1040-1047Revista Caatinga; v. 31 n. 4 (2018); 1040-10471983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/6821/9874Copyright (c) 2018 Revista Caatingainfo:eu-repo/semantics/openAccessMoraes, Carolina Cinto deAraújo, Humberto Sampaio deFactor, Thiago LeandroCalori, Alex HumbertoPurquerio, Luis Felipe Villani2023-07-20T13:56:52Zoai:ojs.periodicos.ufersa.edu.br:article/6821Revistahttps://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:2024-04-29T09:46:31.157172Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
