Resumo: | The objetive of of this work was to compare the diagnostics of the nutritional state of a group of 111 commercial soybean plantations, obtained by Diagnosis and Recommendation Integrated System (DRIS) and Compositional Nutrient Diagnosis (CND) methods applying the response potencial to fertilization concept. It was observed that zinc, phosphorus and iron were the nutrients diagnosed by both methods as the more restrictive for lack, and magnesium and manganese the more restrictive for excess. Agreement between DRIS and CND diagnoses was higher for nutrients considered of greater relative deficiency (90.3%) than for those considered of greater relative excess (81.9%). When the classes of nutritional state were evaluated, the frequency of plantations with concordant diagnosis varied from 85.9% for phosphorus to 98.6% for manganese. DRIS and CND methods tend to be consonants about nutritional status diagnoses; classes grouping of potential response to fertilization may result in grouping in one class of nutritional state nutrients with high and low probability of response. |

Nas lavouras analisadas, observou-se que Zn, P e Fe foram os nutrientes diagnosticados por ambos os métodos como os mais limitantes pela ausência, e Mg e Mn os mais limitantes por excesso. A freqüência de lavouras com diagnósticos concordantes, quanto ao potencial de resposta à adubação, foi maior para os nutrientes considerados de maior deficiência relativa (90,3%), em relação aos considerados de maior excesso relativo (81,9%). Quando se avaliaram os diagnósticos concordantes quanto ao estado nutricional, a freqüência variou de 85,9% para o P a 98,6% para o Mn. Os métodos DRIS e CND tendem a ser concordantes quanto ao diagnóstico nutricional; o agrupamento de classes de potencial de resposta à adubação pode resultar no agrupamento, em uma única classe de estado nutricional, os nutrientes com alta e baixa probabilidade de resposta à adubação.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraUrano, Eliane Oshiro MocelinKurihara, Carlos HissaoMaeda, ShizuoVitorino, Antonio Carlos TadeuGonçalves, Manoel CarlosMarchetti, Marlene Estevão2006-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7298Pesquisa Agropecuaria Brasileira; v.41, n.9, set. 2006; 1421-1428Pesquisa Agropecuária Brasileira; v.41, n.9, set. 2006; 1421-14281678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7298/4343info:eu-repo/semantics/openAccess2014-09-30T20:02:28Zoai:ojs.seer.sct.embrapa.br:article/7298Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-30T20:02:28Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
