Resumo: Gypsum is widely used in agriculture to supply nutrients to the soil-plant system. However, the excessive use of gypsum may lead to a reduction of cationic soil nutrients such as potassium in the most superficial soil layer. Thus, the objective of this study was to evaluate the feasibility of using gypsum and potassium for cauliflower crop nutritional status and commercial production. The experiment was conducted in 5x5 factorial scheme, corresponding to five K doses (0, 100, 180, 240, 360 kg ha-1 of K2O) and five gypsum doses (0, 500, 1000, 2000, 4000 kg ha-1) in dystrophic Red Latosol. Leaf N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn contents, commercial head mass, diameter and height and peduncle diameter were evaluated. The application of 360 kg ha-1 of K2O resulted in 29.69% more K in cauliflower leaf and 18.94% more commercial head mass compared to the non-application of K. The application of 4000 kg ha-1 of gypsum resulted in reductions of leaf S and Mn and increase in leaf Cu. Based on the results observed, 4000 kg ha-1 of gypsum and 360 kg ha-1 K2O could be required for high cauliflower production.

No entanto, seu uso indiscriminado pode levar à redução do conteúdo de nutrientes catiônicos da superfície do solo, principalmente o potássio. Assim, o objetivo deste estudo foi avaliar a viabilidade da utilização de gesso, associado à aplicação de potássio, no cultivo de couve-flor, cultivar Sharon. O experimento foi conduzido em esquema fatorial 5x5, sendo avaliadas cinco doses de K (0, 100, 180, 240 e 360 kg ha-1 de K2O) e cinco doses de gesso (0, 500, 1.000, 2.000 e 4.000 kg ha-1) no delineamento em blocos completos casualizados, com três repetições. Foram determinados os teores foliares de N, P, K, Ca, S, Mg, B, Cu, Fe, Mn e Zn e a massa comercial da cabeça, o diâmetro da cabeça, o diâmetro do pedúnculo e a altura da cabeça. A aplicação de 360 kg ha-1 de K2O resultou no aumento de 29,69% no teor foliar de K e 18,94% na massa comercial da cabeça, em relação à dose de 0 kg ha-1 de K2O. A aplicação da dose máxima de gesso, resultou na redução dos teores foliares de enxofre (14,71%) e manganês (25,11%) e, aumento dos teores foliares de cobre (16,97%). Com base nos resultados observados, conclui-se que para a cultura da couve-flor, as doses de gesso e K2O recomendadas são de, respectivamente, 4.000 e 360 kg ha-1.  Universidade Federal Rural do Semi-Árido2021-05-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/992310.1590/1983-21252021v34n213rcREVISTA CAATINGA; Vol. 34 No. 2 (2021); 370-379Revista Caatinga; v. 34 n. 2 (2021); 370-3791983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/9923/10618Copyright (c) 2021 Revista Caatingainfo:eu-repo/semantics/openAccessCharlo, Hamilton César de OliveiraAlmeida, Juliano da Silva Martins de Moreira, Édimo Fernando AlvesCastoldi, RenataLuz, José Magno QueirozLemes, Ernane Miranda 2023-07-19T12:10:49Zoai:ojs.periodicos.ufersa.edu.br:article/9923Revistahttps://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:2024-04-29T09:46:54.035245Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
