Resumo: | The objectives of this study were to evaluate the relationship between the diagnosis and recommendation integrated system (DRIS) indices and foliar nutrient concentrations, to establish optimum foliar nutrient concentrations with DRIS and to validate the DRIS norms for sugarcane crop. Foliar nutrient concentrations from 126 sugarcane commercial fields were analyzed during the 1996/97 season, to calculate DRIS indices. Regression analysis was used to fit a model relating DRIS indices to nutrient concentrations. Experiments were carried out during the 1997/98 season, whose treatments consisted of the addition of the most limiting nutrients according to DRIS. A new diagnosis was performed. At the end of 1997/98 season, the yields of each plot were collected. Analysis of variance and Duncan test (5%) were used for the evaluation of the collected data. There was a positive and significant relationship between sugarcane foliar nutrient concentrations and DRIS indices. The optimum foliar nutrient concentrations for sugarcane are: 13.4 g ha-1 for N, 1.91 g ha-1 for P, 12.2 g ha-1 for K, 2.99 g ha-1 for Ca, 2.15 g ha-1 for Mg, 1.61 g ha-1 for S, 4.48 mg ha-1 for Cu, 67.8 mg ha-1 for Mn and 11.7 mg ha-1 for Zn. DRIS norms evaluated are useful to correct nutritional imbalances and to increase sugarcane yield. |

Teores foliares de nutrientes de 126 lavouras comerciais de cana-de-açúcar foram analisados durante a safra 1996/97, para o cálculo de índices DRIS. Análise de regressão foi utilizada para ajustar modelo relacionando índices DRIS e teores foliares de nutrientes. Os experimentos foram conduzidos na safra 1997/98, e os tratamentos consistiram na adição dos nutrientes mais limitantes de acordo com a diagnose fornecida pelo DRIS. Posteriormente, nova diagnose nutricional foi realizada. No final da safra 1997/98, foram avaliadas as produtividades das parcelas experimentais. Análise de variância e teste de médias (Duncan, 5%) foram utilizados na avaliação dos dados coletados. Houve relação positiva e significativa entre teores foliares e índices DRIS. Os teores foliares adequados de nutrientes estabelecidos foram: 13,4 g ha-1 de N; 1,91 g ha-1 de P; 12,2 g ha-1 de K; 2,99 g ha-1 de Ca; 2,15 g ha-1 de Mg; 1,61 g ha-1 de S; 4,48 mg ha-1 de Cu; 67,8 mg ha-1 de Mn e 11,7 mg ha-1 de Zn. As normas DRIS avaliadas foram úteis na correção dos desequilíbrios nutricionais e no aumento da produtividade da cana-de-açúcar.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraJunior, Roberto dos Anjos ReisMonnerat, Pedro Henrique2003-03-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6586Pesquisa Agropecuaria Brasileira; v.38, n.3, mar. 2003; 379-385Pesquisa Agropecuária Brasileira; v.38, n.3, mar. 2003; 379-3851678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/6586/3643info:eu-repo/semantics/openAccess2014-08-13T16:39:11Zoai:ojs.seer.sct.embrapa.br:article/6586Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-13T16:39:11Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
