Resumo:  The objective of this work was to indicate possible sowing and transplanting dates for the onion variety Empasc 352 - Bola Precoce cultivated in the Alto Vale do Itajaí region in Ituporanga, Santa Catarina, based on thermal availability per Degree-days above 15°C and photoperiod. Ten sowing dates were used at weekly intervals during four agricultural years,determining the intervals in days for 40 periods between sowing-transplant, sowing-harvest and transplant-harvest at the Epagri Experimental Staton in Ituporanga-SC. The thermal availability did not make transplantng and harvesting unfeasiblethroughout the cultivaton period used. For the sowing-to-transplant phase, there was a decrease in accumulated Degreedays from the first sowing date. There was a trend of compensaton of the average daily Degree-days between the sowing-to transplant phase and the transplant-to-harvest phase. The intermediate sowing tmes showed a trend of equivalence of the average daily thermal availability between the three phases, with the seasons of 12/04 the greatest equality. Based on the results, sowing can be recommended between April 15th and the frst half of May with transplants until August 24th, to meet the thermal needs of the cultivar Empasc 352 - Bola Precoce in the Ituporanga region.

Utilizaram-se 10 datas de semeaduras com intervalos semanais durante quatro anos agrícolas, determinando-se os intervalos em dias para 40 períodos entre semeadura-transplante, semeadura-colheita e transplante-colheita na Estação Experimental de Ituporanga (Epagri/EEItu), em SC. A disponibilidade térmica não inviabilizou o transplante e a colheita ao longo do período de cultvo utilizado. Para a fase semeadura ao transplante, ocorreu uma diminuição dos Graus-dias acumulados a partr da primeira época de semeadura. Ocorreu uma tendência de compensação dos Graus-dias médios diários entre as fases semeadura ao transplante e a fase de transplante à colheita. As épocas de semeadura intermediárias mostraram uma tendência de equivalência da disponibilidade térmica média diária entre as três fases, tendo as épocas de 12/04 a maior igualdade. Baseado nos resultados, podem-se recomendar as semeaduras entre 15 de abril e a primeira quinzena de maio com os transplantes até 24 de agosto, para atender a necessidade térmica do cultvar Empasc 352 - Bola Precoce na região de Ituporanga.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2021-12-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/104710.52945/rac.v34i3.1047Agropecuária Catarinense Journal; Vol. 34 No. 3 (2021); 37-42Agropecuária Catarinense; v. 34 n. 3 (2021); 37-422525-60760103-0779reponame: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/1047/1219Copyright (c) 2021 Hamilton Justino Vieirahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessVieira, Hamilton Justinode Menezes Junior, Francisco Olmar Gervini Blainski, Everton Miszinski, Joelma2022-06-22T11:42:32Zoai:ojs.publicacoes.epagri.sc.gov.br:article/1047Revistahttps://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:2022-06-22T11:42:32Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
