Resumo: The objective of this research was to evaluate the effects of rates and sources of potassium in top dressing on yield of cabbage hybrid Kenzan. Two experiments were conducted (15/07 to 22/11/2010 and 28/09/2010 to 27/01/2011) and nine treatments, resulted from a factorial 4 rates (0; 45; 90; 135 and 180 kg ha-1 of K2O) x 2 sources (KCl and K2SO4) + 1 control (without K in top dressing) were evaluated at randomized block design, with 4 replicates. After the harvest, fresh and dry weight of cabbage head and of external leaves; leaf number (from cabbage and external); diameter and height of cabbage head were evaluated. It was evaluated soil chemical characteristics at the end of first experiment and content of macro and micronutrients in plants. It was observed that potassium rates and sources did not influence most of evaluated characteristics. K content in plant increased linearly with KCl application. Results obtained show that, probably, it is not necessary application of K in top dressing when base fertilization is done with this nutrient, besides existing recommendations for this crop.

Foram conduzidos dois experimentos (15/07 a 22/11/2010 e 28/09/2010 a 27/01/2011) e avaliados 9 tratamentos, resultantes do fatorial 4 doses (45; 90; 135 e 180 kg ha-1 de K2O) x 2 fontes (cloreto e sulfato de potássio) + 1 testemunha (sem potássio em cobertura), no delineamento experimental de blocos casualizados, com 4 repetições. Após a colheita, foram avaliados a massa fresca e seca da cabeça e das folhas externas, número de folhas, diâmetro e altura da cabeça. Apenas no primeiro experimento foram avaliadas características químicas do solo ao final do ciclo e teores de macro e micronutrientes na planta. Observou-se que as doses e fontes de potássio em cobertura não influenciaram a maioria das características avaliadas. Os teores de potássio na planta aumentaram linearmente com as doses de cloreto de potássio. Os resultados obtidos demonstram que, provavelmente, não é necessária a aplicação de potássio em cobertura quando já se faz a adubação de plantio com este nutriente, apesar das recomendações existentes para a cultura.UEL2013-10-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de CampoPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1109110.5433/1679-0359.2013v34n5p2129Semina: Ciências Agrárias; Vol. 34 No. 5 (2013); 2129-2138Semina: Ciências Agrárias; v. 34 n. 5 (2013); 2129-21381679-03591676-546Xreponame:Semina.
