“…De maneira semelhante, Parent et al (1994), ao avaliar desequilíbrios nutricionais em plantios de batata, observaram alta correlação entre os índices DRIS e CND; e Raghupathi & Bhargava (1998) verificaram alta correlação entre os índices de equilíbrio nutricional, produzidos para diagnósticos de romãzeiros, pelos métodos DRIS e CND, que indicaram, também, boa concordância no diagnóstico do desequilíbrio geral de nutrientes por ambos os métodos.…”

Resumo -O objetivo deste trabalho foi comparar os diagnósticos do estado nutricional de um conjunto de 111 lavouras comerciais de soja, pelos métodos: Sistema Integrado de Diagnose e Recomendação (DRIS) e Diagnose da Composição Nutricional (CND), com uso do conceito de potencial de resposta à adubação. 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.Termos para indexação: Glycine max, diagnose foliar, deficiência nutricional. Soybean nutritional status evaluationAbstract -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.

Nutrition and fertilization are important factors in determining fruit yield and fruit quality. There are several methods for plant nutritional status diagnosis, among them, two are relevant and named as Sufficiency Range Approach (SRA) and Diagnosis and Recommendation Integrated System (DRIS). This research reports the main concepts and applications of DRIS in nutritional diagnosis of fruit crops, comparing it with current nutritional diagnosis methods, indicating advantages and disadvantages, and possible limitations to be investigated. Key words: foliar analysis, fruit crops, mineral nutrition DRIS: CONCEITOS E APLICAÇÕES NA DIAGNOSE NUTRICIONAL EM PLANTAS FRUTÍFERASRESUMO: A nutrição e a adubação são fatores determinantes na produtividade dos pomares e na qualidade de frutos. Dentre os diversos métodos de diagnose nutricional das plantas, destacam-se o critério de faixas de suficiência (CFS) e o sistema integrado de diagnose e recomendação (DRIS -"Diagnosis and Recommendation Integrated System"). São relatados neste trabalho os principais conceitos e aplicações do método DRIS na diagnose nutricional em fruteiras, comparando-o com os sistemas atuais de diagnose nutricional, apontando vantagens e desvantagens, e possíveis limitações a serem investigadas. Palavras-chave: análise foliar, fruticultura, nutrição mineral

“…DRIS has shown its application in both annual crops, viz., lettuce (Sanchez et al 1991 ) , tomato (Caron and Parent 1989 ) , potato (Parent et al 1994a) , onion (Caldwell et al 1994, cucumber (May fi eld et al 2002 ) , and carrot (Parent et al 1994b ) as well as perennial crops, viz., apple (Goh and Malakouti 1992 ) , grapes (Bhargava and Raghupathi 1995 ) , pecan (Beverly and Worley 1992 ) , peach (Sanz 1999 ) , mango (Schaffer et al 1988 ) , mango (Raghupathi and Bhargava 1999 ) , pomegranate (Raghupathi and Bhargava 1998 ) , banana (Angeles et al 1993 ) , sapota (Appa Rao et al 2006 ) , litchi (Hundal and Arora 1996 ) , and papaya (Bowen 1992 ) with equally reproducing results. To overcome perceived weakness in the traditional DRIS approach to tissue nutrient analysis interpretation, three revisions and two new methods were applied to data for oranges cv Valencia.…”
