Resumo: Abstract: The objective of this study was to evaluate the influence of N doses on yield and quality of tomato fruits in a notill system. The research was carried out at field conditions in Epagri - Experimental Station of Caçador, SC, Brazil, during the growing seasons 2006/07 and 2007/08. The treatments were set in a CRB design, with four replications. Treatments were six doses of N, as ammonium nitrate, being 0, 125, 250, 375, 500 and 625 kg ha-1 in 2006/07 and for 2007/08 to 0, 150, 300, 450, 600 e 750 kg ha-1 in 2007/08. The total, commercial, extra AA and extra A, tomato yields followed a quadratic model in response to N rates in the 2006/07 crop. However in 2007/08 there was a linear effect. The maximum technical efficiency (MTE) and maximum economic efficiency (MEE) for commercial fruit yield in 2006/07 crop were obtained with N rates of 555 and 546 kg ha-1. For the average mass of extra AA fruits; commercial fruit production in relation to total production and; production of extra AA fruits in relation to commercial production in 2006/07 crop, there was a quadratic fit with increased levels of N applied, and their maximum points with 478, 486 and 557 kg ha-1 N, respectively, that is, next to the doses of MTE and MEE for commercial fruit yield.

Dois experimentos foram realizados em campo na Epagri/Estação Experimental de Caçador durante as safras 2006/07 e 2007/08. Utilizou-se o delineamento blocos ao acaso com quatro repetições. Os tratamentos foram seis doses de N, como nitrato de amônio, sendo aplicados 0, 125, 250, 375, 500 e 625kg ha-1 para a safra 2006/07 e 0, 150, 300, 450, 600 e 750kg ha-1 na safra 2007/08. Na safra 2006/07, houve ajuste quadrático em resposta às doses de N para as produtividades de frutos de tomate total, comercial, extra AA e extra A. Entretanto, na safra 2007/08 houve efeito linear. Na safra 2006/07, as máximas eficiências técnica (MET) e econômica (MEE) para produtividade comercial de frutos foram obtidas com doses de N de 555 e 546kg ha-1. Para massa média dos frutos extra AA, produção de frutos comerciais em relação à total e produção de frutos extra AA em relação à produção comercial, safra 2006/07, houve ajuste quadrático com o aumento dos níveis de N aplicados, sendo seus pontos de máxima com 478, 486 e 557kg ha-1 de N respectivamente, isto é, próximos às doses de MET e MEE para a produtividade comercial de frutos. Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2017-10-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/186Agropecuária Catarinense Journal; Vol. 28 No. 1 (2015); 87-91Agropecuária Catarinense; v. 28 n. 1 (2015); 87-912525-60760103-0779reponame: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/186/94Copyright (c) 2017 Revista Agropecuária Catarinenseinfo:eu-repo/semantics/openAccessMueller, SiegfriedWamser, Anderson FernandoSuzuki, Atsuo2020-07-07T04:58:15Zoai:ojs.publicacoes.epagri.sc.gov.br:article/186Revistahttps://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:2020-07-07T04:58:15Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
