Resumo: The Diagnosis and Recommendation System (DRIS) was applied to eucalypt trees (hybrids of Eucalyptus grandis x E. urophylla) with different ages and growing under different environmental conditions for three different clones. The basic data were obtained from 1,986 trees of commercial stands cultivated in the states of Espírito Santo and south Bahia, Brazil. The DRIS indices were calculated using the Beaufils' Range formula and grouped according to the Nutrient Application Potential Response method. The objective of this paper was to evaluate the N, P and Ca status in eucalypt trees, regarding the tree ages and genetic materials. The DRIS indices discriminated differences in the nutritional status of the trees, both in relation to age and the genetic materials (clones). The results indicated that the deficiency of N and Ca tended to decrease with tree age, whereas the P deficiency tended to increase. Furthermore, of the three evaluated clones, those numbered 00014 and 00034 showed opposite trends regarding to N, P, and Ca nutrition, and the clone numbered 00021, in general, presented the highest degree of unbalanced nutrition of N, P and Ca.

Foram usadas informações de 1.986 árvores, híbridos de Eucalyptus grandis x E. urophylla, de talhões comerciais cultivados nos estados do Espírito Santo e sul da Bahia. Os índices DRIS foram calculados pela fórmula das Faixas de Beaufils e interpretados pelo método do Potencial de Resposta à Adubação, avaliando-se o estado nutricional quanto ao N, P e Ca nas árvores de eucalipto em relação à idade da árvore e ao material genético. Os índices DRIS obtidos nessas condições mostraram-se capazes de reconhecer diferenças no estado nutricional das árvores, tanto em relação à idade quanto ao tipo de material genético. Os resultados indicaram que a deficiência de N e de Ca diminuem com a idade da árvore, enquanto aumenta a deficiência de P. Além disso, dos três clones estudados, os de número 00014 e 00034 apresentaram tendências opostas quanto à nutrição com N, P e Ca, e o clone 00021 foi o que apresentou, de modo geral, maior grau de desequilíbrios nutricionais de N, P e Ca.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraWadt, Paulo Guilherme SalvadorNovais, Roberto Ferreira deAlvarez, Victor HugoBarros, Nairam Félix deDias, Luiz Eduardo1999-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5511Pesquisa Agropecuaria Brasileira; v.34, n.10, out. 1999; 1797-1803Pesquisa Agropecuária Brasileira; v.34, n.10, out. 1999; 1797-18031678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5511/2702info:eu-repo/semantics/openAccess2012-02-13T11:38:31Zoai:ojs.seer.sct.embrapa.br:article/5511Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-02-13T11:38:31Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
