Potencial de resposta à adubação para N, P, K, Ca e Mg em cupuaçueiros avaliados por diferentes normas DRIS / Response potential to fertilization response for N, P, K, Ca and Mg in cupuaçueiros evaluated by different DRIS standards

O potencial de resposta à adubação é uma ferramenta utilizada para a interpretação dos valores dos índices DRIS, de forma que pode ser útil para verificar se diferentes grupos de normas resultam em diagnósticos distintos ou semelhantes entre si. Neste sentido, objetivou-se avaliar o comportamento do diagnóstico nutricional, submetidos a cinco grupos de normas DRIS. Para isto, amostras foliares de cupuaçueiros foram coletadas de pomares comerciais, cuja idade das plantas variou de 5 a 18 anos, sob monocultivo e sistemas agroflorestais (SAF's), obtendo-se para cada relação nutricional entre os nutrientes N, P, K, Ca, Mg, as normas DRIS bivariadas, as quais foram obtidas para o conjunto das populações monitoradas e para subpopulações específicas. As diferentes normas DRIS resultaram em diagnósticos semelhantes para N, P e Ca, enquanto que para K e Mg os diagnósticos produzidos distinguiram-se entre as normas resultando em desvios nutricionais.

The response of potential fertilization is a tool used to interpret the values of DRIS indices, so that it may be useful to see if different groups of rules might result in different or similar diagnosis among themselves. In this sense, it we aimed to evaluate the performance of the nutritional diagnosis, submitted to five groups of DRIS norms. For this, leaf samples were collected from commercial cupuaçueiro orchards, whose plant ages ranged from 5 to 18, with cropping or agroforestry (SAF). For each relationship among the nutrition nutrients N, P, K, Ca and Mg, we obtained bivariate DRIS standards for all populations and monitored for specific subpopulations. The different standards resulted in DRIS diagnoses similar for N, P and Ca and distinct for Mg and K the produced diagnoses stood out among the norms resulting in nutritional deviations.

Relações nutricionais log-transformadas para avaliação nutricional de cupuaçueiros comerciais / Log-transformed nutrient ratio for evaluation nutritional of cultivated cupuaçu trees

A transformação logarítmica das relações bivariadas no cálculo das normas e dos índices do sistema integrado de diagnose e recomendação de nutrientes (DRIS) tem sido sugerida como uma forma de melhorar a acurácia do sistema, principalmente por diminuir a inconsistência na distribuição de freqüência entre as formas de expressão direta e inversa de uma mesma relação. Neste sentido, o objetivo deste trabalho foi avaliar o uso de relações log-transformadas entre diferentes populações de referência. Amostras foliares de cupuaçu foram coletadas de 153 pomares comerciais, cuja idade das plantas variou de 5 a 18 anos, cultivados em monocultivo ou sistemas agroflorestais, obtendo-se para cada relação nutricional entre os nutrientes N, P, K, Ca, Mg, Fe, Cu, Zn, e Mn as normas DRIS bivariadas log-transformadas e não transformadas, obtidas para o conjunto da população e para condições específicas. Os resultados mostraram que as relações log-transformadas contribuem para uma maior consistência dos resultados entre as formas direta e inversa entre diferentes normas DRIS.

The logarithmic transformation of the bivariate relationships in the calculation of integrated system of diagnosis and recommendation indices (DRIS) has been suggested as a way to improve the accuracy of the system, mainly by reducing the inconsistency between the frequency distribution of the forms expression of direct and inverse of the same relationship. Accordingly, the objective of this study was to evaluate the use of log-transformed relationship between different populations of reference. Cupuaçu leaf samples were collected at 153 commercial orchards; trees were part of either monoculture or agroforestry systems and ranged from 5 to 18 years old. For each individual, the nutritional relationship was calculated for the nutrients: N, P, K, Ca, Mg, Fe, Cu, Zn and Mn. Log-transformed and no- transformed nutrient ratio were obtained for the entire population and specific conditions.The results showed that the log-transformed relationship contributes to greater consistency of results between the direct and inverse forms between DRIS norms.
