Resumo: The objective of the work was to evaluate the phenological patterns of the onion cultivar Empasc 352 - Bola Precoce, when submitted to different climatic and photoperiodic conditions of the subtropical climate of Santa Catarina, SC, Brazil. The treatments consisted of 10 sowing times, separated by one week, repeated from 03/15 to 05/17 for four years. From the results, a non-linear relationship was observed between the sowing dates and the duration in days until transplantation, represented by a second-degree polynomial regression. The later sowing dates showed a significant increase in the sowing-transplant duration. As the sowing seasons were postponed, there was a decrease in the period between transplant-harvest. The relationship between the duration of the sowing-transplant and transplant-harvest phase was reversed, that is, a longer duration of the sowing-transplant phase and shorter in the transplant-harvest phase. It is concluded, therefore, that the sowing date is important for the onion cycle duration. Every two days of advance on the sowing date corresponded to three days on the transplant date.

Os tratamentos consistiram de 10 épocas de semeaduras, distanciadas em uma semana, repetidas no período 15/03 à 17/05 em quatro anos. Os resultados revelam que a relação entre as datas de semeadura e a duração em dias até o transplante não é linear, podendo ser representada por um polinômio de segundo grau, onde as últimas datas de semeaduras apresentam um significativo aumento na duração semeadura-transplante. À medida em que as épocas de semeaduras foram postergadas ocorreu uma diminuição do período entre transplante-colheita. A relação entre a duração da fase semeadura-transplante e transplante-colheita foi inversa, ou seja, maiores durações da fase semeadura-transplante menores as fases de transplante-colheita. A data de semeadura foi o principal responsável pela variação da duração do ciclo da cebola. Para cada dois dias de avanço na data de semeadura ocorreu uma postergação na data de transplante em três dias.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2021-04-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/103910.52945/rac.v34i1.1039Agropecuária Catarinense Journal; Vol. 34 No. 1 (2021); 67-71Agropecuária Catarinense; v. 34 n. 1 (2021); 67-712525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/1039/1039Copyright (c) 2021 Hamilton Justino Vieirahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessVieira, Hamilton JustinoJunior, Francisco Olmar Gervini MenezesBlainski, EvertonMiszinski, JoelmaNeto, João Vieira2021-08-20T17:15:08Zoai:ojs.publicacoes.epagri.sc.gov.br:article/1039Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2021-08-20T17:15:08Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
