RESUMODiferentes procedimentos referentes do método do sistema integrado de diagnose e recomendação podem influenciar a acurácia da diagnose foliar da mangueira. Assim, o objetivo deste estudo foi comparar diagnósticos do estado nutricional da mangueira obtidos através de diferentes métodos de avaliação do estado nutricional, comparando-se relações multivariadas (método CND) com relações bivariadas (método DRIS), ou seja, com variações quanto ao uso de normas específicas ou preliminares e à transformação logarítmica dos dados. Foram utilizados resultados de análises de teores foliares de macro e micronutrientes de 63 pomares de mangueira do Vale do Submédio São Francisco. Para a interpretação dos índices nutricionais através do critério do Potencial de Resposta à Adubação. Os métodos CND e DRIS, com e sem transformação logarítmica e se usando normas específicas ou preliminares, as quais apresentaram desempenho semelhante na avaliação do estado nutricional da mangueira no Submédio São Francisco. Nos pomares de manga do semiárido nordestino as deficiências de micronutrientes (Zn, Fe e Cu) foram mais frequentes que a deficiência de macronutrientes. Palavras-chave: Mangifera indica, diagnose foliar, equilíbrio nutricionalNutritional status of mango determined by DRIS and CND methods ABSTRACT Different procedures for the integrated method of diagnosis and recommendation may influence the accuracy of foliar diagnosis of mango. Thus, the objective of this study was to compare the diagnosis of nutritional status of mango obtained by different methods of assessing nutritional status, comparing multivariate relations (method CND) with bivariate relationships (DRIS) i.e., variations in the use of specific or preliminary standards and a logarithmic transformation of the data. The macro and micronutrient leaf analysis results of 63 mango orchards of Lower-middle São Francisco River Valley, Brazil, were used. To interpret nutritional status the Potential Response to Fertilization (PRA) criteria was used. The CND and DRIS methods, with and without logarithmic transformation and using specific or preliminary standards, which showed similar performance in assessing the nutritional status of the mango in Lower-middle San Francisco. Mango orchards in the semiarid region of northeast Brazil, the micronutrient deficiencies (Zn, Fe and Cu) were more frequent than macronutrient deficiency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
