Resumo: In Alto Vale do Itajaí region, Santa Catarina State, rice fields are located at elevations ranging between 300 and 600m. This condition predisposes the region to weather phenomena that may interfere on growth and development process of rice crop, reflecting on grain yield. The aim of this study was to evaluate the dose and installment of N application for lowland rice at the altitude zones of that region. The experiments were conducted in Rio do Campo (600 m over the sea), SC, in 2012/13 and 2013/14 growing seasons. The treatments consisted in the combination of the factors dose of N and fertilizer installment. The climate effects on the rice response to nitrogen fertilization were evaluated by incorporating the factor cropping year in the statistical model. Temperature and solar radiation variations that occurred in the reproductive phase have no effect in yield response of rice to N fertilization in the Alto Vale do Itajaí region. The dose and installment of N fertilization in that region, can be 90 kg of N ha-1, carried in two applications, with no prejudice to the agronomical performance of lowland rice.

Esta condição predispõe a região à ocorrência de fenômenos climáticos que podem interferir nos processos de crescimento e desenvolvimento da cultura, com reflexos sobre a produtividade de grãos. O objetivo deste estudo foi avaliar doses e parcelamento da aplicação de N para o arroz irrigado em zonas de altitude desta região. Os experimentos foram conduzidos em Rio do Campo, SC (600m de altitude), nas safras 2012/13 e 2013/14. Os tratamentos consistiram na combinação dos fatores doses de N e parcelamento da adubação. Os efeitos do clima sobre a resposta do arroz ao manejo da adubação nitrogenada foram avaliados por meio da incorporação do fator ano de cultivo ao modelo estatístico. As variações de temperatura e radiação solar ocorridas na fase reprodutiva não têm efeito sobre a resposta produtiva do arroz à adubação nitrogenada na região do Alto Vale do Itajaí. A dose e parcelamento da adubação nitrogenada para lavouras dessa região podem ser 90kg de N ha-1, em duas aplicações em cobertura, sem prejuízos ao desempenho produtivo do arroz irrigado.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2017-12-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/3410.52945/rac.v30i3.34Agropecuária Catarinense Journal; Vol. 30 No. 3 (2017); 72-78Agropecuária Catarinense; v. 30 n. 3 (2017); 72-782525-60760103-0779reponame: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/34/150Copyright (c) 2017 Revista Agropecuária Catarinensehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSchmidt, FabianaVale, Marcos Lima Campos doKnoblauch, RonaldirVerdi, RicieriSchwartz, Dirceu2020-07-03T17:38:23Zoai:ojs.publicacoes.epagri.sc.gov.br:article/34Revistahttps://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:2020-07-03T17:38:23Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
