“…In contrast, higher accuracy with the use of specific norms considering different ages or plant stages was observed for crops such as eucalypt (Eucalyptus spp.) (Wadt et al, 1999) and passion fruit (Passiflora edulis) (Carvalho et al, 2011). Diverging results in the literature reinforce the need to evaluate DRIS norms according to plant development stages before applying these standard relationships to commercial diagnostics.…”

ABSTRACT:The oil palm crop has expanded significantly in the state of Pará, which has not been followed in a proportional manner by studies aiming at increasing yield through plant nutrition. The objective of this study was to evaluate general and specific norms of the Diagnosis and Recommendation Integrated System (DRIS) for genetic materials of oil palm (African and interspecific hybrid) at two ages (young and adult plants) and evaluate possible deficiencies in fertilization and soil correction practices. The DRIS norms were composed of means, standard deviations, and coefficients of variation of bivariate, specific, and general relationships among nutrients of 144 leaf samples. The DRIS norms specific for genetic material did not differ from the general norms; however, a large number of differences were found between specific bivariate relationships for age groups, among themselves, and in relation to the general norms. The regression analysis between the nutritional balance index and yield were better explained when age groups were discriminated. In the young plants, the number of cases of stands with deficiencies followed the order Ca > Fe > B > S > Mn > K > Mg = Cu > Zn > N > P; and for adults, this order was Ca > Mn > Zn > Fe > S = B > N = Cu > K > Mg > P. The DRIS norms can be utilized in diagnostics regardless of genetic material; however, they must be specified for the age of the plant. Most of the stands showed deficiency in Ca and micronutrients, coinciding with the least used nutrients in oil palm crops in the state of Pará, as well as emphasizing the need for soil liming.

“…The DRIS theory was developed with a universal character to make accurate diagnoses, regardless of the growing region, plant part, or phenological stage of the plant (Jones Jr, 1993) and cultivar (Reis Jr and Monerat, 2002), but the studies have diverged from these premises (Silva et al, 2005;Carvalho et al, 2011;. Martín et al, 2013).…”

“…Portanto, a fim de validar os resultados apresentados, ou aumentar a precisão dos métodos ChM, DRIS e CND, é importante que outras avaliações sejam realizadas, para aumentar o banco de dados e testar o efeito de amostragens em várias épocas do ano. Nesse sentido, tanto o DRIS, na cultura do maracujá (Carvalho et al, 2011), como o CND, na de arroz de sequeiro (Tomio et al, 2015), tiveram seus padrões nutricionais alterados, quando a amostragem foi feita em período próximo da época de colheita.…”

Resumo -O objetivo deste trabalho foi determinar níveis críticos e faixas de suficiência de nutrientes para a palma-de-óleo (Elaeis spp.), a partir de métodos de avaliação do estado nutricional das plantas. Utilizaram-se os métodos chance matemática (ChM), sistema integrado de diagnose e recomendação (DRIS) e diagnose da composição nutricional (CND), além da avaliação do nível crítico obtido pela distribuição normal reduzida (DNR) em dados de produtividade e do teor de nutrientes de 144 amostras foliares de plantios no Pará. As regressões dos índices DRIS e CND com os teores foliares foram todas significativas, e o menor coeficiente de determinação foi encontrado para N. Os intervalos das faixas de suficiência obtidos com os métodos ChM, DRIS e CND nos talhões nutricionalmente equilibrados foram, em geral, mais estreitos do que os reportados na literatura, com poucos diagnósticos concordantes, sobretudo para K. Os níveis críticos obtidos pela DNR situaram-se dentro do intervalo das faixas nutricionais obtidas com os outros métodos. Os métodos ChM, DRIS, CND e DNR são adequados para a obtenção de valores de referência nutricionais e indicaram N, Ca, S, Mn e Zn como os nutrientes com maior frequência de deficiência nos talhões de palma-de-óleo avaliados.Termos para indexação: Elaeis guineensis, Elaeis oleifera, chance matemática, diagnose da composição nutricional, DRIS, nutrição de plantas. Critical levels and nutrient sufficiency ranges derived from methods for assessing the nutritional status of oil palmAbstract -The objective of this work was to determine critical levels and nutrient sufficiency ranges for oil palm (Elaeis spp.), using methods for assessing the nutritional status of the plants. The methods of mathematical chance (ChM), diagnosis and recommendation integrated system (DRIS), and compositional nutrient diagnosis (CND), besides the critical level obtained by the reduced normal distribution (DNR), were used in productivity data and in nutrient content of 144 leaf samples of oil palm plantations in the state of Pará, Brazil. The regressions of the DRIS and CND indexes with leaf nutrient contents were all significant, and the lowest coefficient of determination was found for N. The sufficiency range intervals obtained with the ChM, DRIS, and CND methods in the nutritionally balanced stands were, in general, narrower than the ones reported in the literature, with few concordant diagnostics, mainly for K. The critical levels obtained with DNR were within the nutritional range intervals obtained with the other methods. ChM, DRIS, CND, and DNR are suited methods for obtaining nutritional reference values, and they indicated N, Ca, S, Mn, and Zn as the nutrients with the highest frequency of deficiency in the evaluated oil palm orchards.

“…Foliar concentrations of N, P and K were relatively low in all hybrids of yellow passion fruit at 300 DAP (Table 3), while for the other nutrients the concentrations observed are in the range considered adequate for the culture (Carvalho et al, 2001(Carvalho et al, , 2011Menzel et al, 1993). The low concentrations in leaves, particularly of N, P and K, were expected, since this was the first crop in a deforested area with a soil with naturally low fertility and with no application of soluble and concentrated fertilizers.…”

The objective of this work was to evaluate 14 hybrids intraspecific of yellow passion fruit aiming to select those with higher performance in an organic production system in Lençóis, Bahia, Brazil. The following variables were evaluated: Plant growth rate index, segregation for peel color, accumulated productivity, fruit physical-chemical attributes, severity of virus disease in plants and fruits, scabs in fruits and overall state of health of plants. Hybrids HFOP-05, BRS Sol do Cerrado and BRS Gigante Amarelo presented highest plant vigor with no direct relation to the percentage of flowering and fruitification of plants. Some hybrids presented yellow, light purple and dark purple peel color. Fruits with dark purple peel presented interesting chemical characteristics, such as lower acidity and greater ratio, providing sweeter flavor of the fruits. There was no differentiated response of the hybrids as to severity of the diseases evaluated. Leaf analysis showed relatively low concentration only for N, P and K. The hybrids selected, BRS Gigante Amarelo, BRS Sol do Cerrado, HFOP-08, HFOP-09, HFOP-11 and HFOP-12 are highlighted for productivity, physical characteristics of fruits and preference of the consumer market being considered an alternative for passion fruit producers that opt for a more environmental friendly production with greater market value.
