Resumo: The increase in plant density, combined with the use of hybrids in onion cultivation, has provided significant gains in yield, with a direct impact on the amount of absorbed macronutrients. The present work aimed to evaluate the yield and quality of two onion cultivars under a densified system as a function of potassium doses supplied via fertirrigation. A randomized complete block design was used in a 2 x 7 factorial scheme with four replications. The treatments consisted of two cultivars (IPA 11 and Rio das Antas) and seven potassium doses (0, 70, 140, 210, 280, 350 and 420 kg ha-1 K2O), provided by fertigation. The potassium doses that provided maximum total and commercial yields were 215 and 216 kg ha-1 of K2O, respectively. The soluble solids and the percentage of bulbs of classes 2, 3 and 4 were not influenced by potassium fertilization. There was a reduction in the percentage of non-commercial bulbs with the increase of potassium doses. The dose with maximum economical efficiency was 210.6 kg ha-1 of K2O, responsible for a commercial yield of 61.8 t ha-1.

Adotou-se o delineamento em blocos casualizados, em esquema fatorial 2 x 7, com quatro repetições. Os tratamentos constituíram-se de duas cultivares (IPA 11 e Rio das Antas) e sete doses de potássio (0, 70, 140, 210, 280, 350 e 420 kg ha-1 de K2O), fornecidas via fertirrigação. As doses de potássio que proporcionaram as máximas produtividades total e comercial de bulbos foram de 215 e 216 kg ha-1 de K2O, respectivamente. Os sólidos solúveis e o percentual de bulbos das classes 2, 3 e 4 não foram influenciados pela adubação potássica. Houve redução do percentual de bulbos não comerciais com o aumento das doses de potássio. A dose de máxima eficiência econômica foi de 210,6 kg ha-1 de K2O, responsável por uma produtividade comercial de 61,8 t ha-1.Universidade Federal Rural do Semi-Árido2019-11-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/839010.1590/1983-21252019v32n404rcREVISTA CAATINGA; Vol. 32 No. 4 (2019); 889-896Revista Caatinga; v. 32 n. 4 (2019); 889-8961983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/8390/10098Copyright (c) 2019 Revista Caatingainfo:eu-repo/semantics/openAccessGonçalves, Francisco das ChagasGrangeiro, Leilson CostaSousa, Valdívia de Fátima Lima deJesus, Priscila Maylana Modesto deSilva, Gerlani Alves da2023-07-20T17:51:49Zoai:ojs.periodicos.ufersa.edu.br:article/8390Revistahttps://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:2024-04-29T09:46:39.471222Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
