Resumo: | This study aimed to evaluate the effect of phosphate fertilization, with and without foliar application of zinc for producing iceberg lettuce. The experiment was conducted in the Federal Institute of Triângulo Mineiro (IFTM), campus Uberaba, in the field area. The experimental design was randomized blocks, in a 5 x 2 factorial scheme with 4 replications. Five phosphorus doses were evaluated (50%, 75%, 100%, 150%, 200% of the recommended amount of P2O5) with or without foliar application of zinc (0.5 kg.ha-1). There was a significant effect for the characteristics total fresh mass and commercial fresh mass of the plant only regarding the factor phosphorus levels. We conclude that for iceberg lettuce, Lucy Brown cultivar, grown in the region of Uberaba, Minas Gerais, Brazil, it is not recommended to use a zinc-based foliar fertilizer, since this does not provide significant differences in crop yield and phosphate fertilization must have a 50% increase in the currently recommended dose. |

O objetivo deste estudo foi avaliar o efeito da adubação fosfatada, com e sem aplicação foliar de zinco na produção de alface americana. O experimento foi conduzido no Instituto Federal do Triângulo Mineiro (IFTM), campus Uberaba, em área de campo. O delineamento experimental foi de blocos casualizados, em esquema fatorial 5 x 2, com quatro repetições. Foram avaliadas cinco doses de fósforo (50%, 75%, 100%, 150%, 200% da quantidade recomendada de P2O5) com ou sem aplicação foliar de zinco (0,5 kg.ha-1). Houve efeito significativo para as características massa fresca total e massa fresca comercial da planta apenas em relação ao fator doses de fósforo. Conclui-se que para a alface americana, cultivar Lucy Brown, cultivada na região de Uberaba-MG não se recomenda a utilização de adubo foliar à base de zinco, já que este não proporciona diferenças significativas na produtividade da cultura e deve-se aumentar a adubação fosfatada em 50% da dose atualmente recomendada.Universidade Federal de Santa Catarina2015-01-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2015v28n1p3110.5007/2175-7925.2015v28n1p31Biotemas; v. 28 n. 1 (2015); 31-352175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2015v28n1p31/28846Copyright (c) 2015 Amanda Letícia da Silveira, Antonio Pizolato Neto, Amanda Rosa Custódio de Oliveira, Larissa Nogueira de Souza, Hamilton César de Oliveira Charloinfo:eu-repo/semantics/openAccessda Silveira, Amanda LetíciaNeto, Antonio Pizolatode Oliveira, Amanda Rosa Custódiode Souza, Larissa NogueiraCharlo, Hamilton César de Oliveira2017-10-19T16:47:58Zoai:periodicos.ufsc.br:article/33770Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2017-10-19T16:47:58Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
