“…Das noventa relações consideradas entre as concentrações de nutrientes nas folhas, sessenta e duas foram significativas pelo teste F. Entre as relações da subamostra de plantas de alta produtividade cuja significância da relação entre variâncias foi estatisticamente superior, foram selecionadas quarenta e quatro relações: P/N, N/K, N/Ca, N/Mg, N/B, N/Zn, N/Mn, Fe/N, Cu/N, P/K, Ca/P, B/P, P/Zn, P/Mn, Fe/P, Cu/P, Ca/K, Mg/K, K/B, K/Zn, K/Mn, Fe/K, Cu/K, Ca/Mg, Ca/B, Ca/Zn, Ca/Mn, Ca/Fe, Cu/Ca, Mg/B, Mg/Zn, Mn/Mg, Fe/Mg, Cu/Mg, B/Zn, Mn/B, Fe/B, Cu/B, Fe/Zn, Cu/Zn, Mn/Zn, Mn/Fe, Cu/Mn e Cu/Fe (Quadro 3), cujos valores das normas estão no Quadro 4. Raghupathi et al (2004), para a manga, cv. Totapuri selecionaram quarenta e cinco expressões de nutrientes como normas de diagnose.…”

“…O maior desequilíbrio de nutrientes resultou em menor produção de frutos. Aplicou-se Análise dos Componentes Principais (PCA) para extrair a estrutura de correlação entre os nutrientes em plantas de baixa e de alta produtividade e dos índices DRIS (Raghupathi et al,2004). Hundal et al (2005) utilizaram o DRIS para identificar o 'status' de nutrients em frutos de mangueiras em Punjab, India.…”

Este trabalho teve por objetivo estabelecer as normas do sistema integrado de diagnose e recomendação (DRIS) para manga, variedade Tommy Atkins. Foram avaliados sessenta e três pomares comerciais representativos do Submédio do Vale do Rio São Francisco, no Nordeste do Brasil. A região não dispõe de um conjunto de normas de diagnose de tecidos foliares para o cultivo, sendo o diagnóstico do estado nutricional e as recomendações de fertilização baseados em faixas de teores de nutrientes em folhas de mangueira cultivadas em diferentes regiões. Foram coletadas amostras de folhas para análise química, antes da aplicação de quebradores de dormência de brotos. As normas DRIS para nutrição das plantas foram estabelecidas com base em um banco de dados criado nesta pesquisa, envolvendo os nutrientes N, P, K, Ca, Mg, B, Cu, Fe, Mn e Zn. Essas normas foram estabelecidas considerando uma subpopulação de plantas com produção igual ou superior a 250 kg/planta, produção essa representativa para as condições ambientais da principal zona produtora de manga do país. Das noventa relações consideradas entre nutrientes, sessenta e duas foram significativas pelo teste F, das quais, quarenta e quatro foram selecionadas como normas para a cultura.

“…The DRIS is an example of an attempt to include elemental interactions in a diagnosis system using ratios between elemental concentrations and, in its most advanced form, even including interactions with and between soil composition, farming practices and other yield influencing variables ( Sumner and Beaufils, 1975 ). The vast data collection, however, makes DRIS relevant only for high value crops, such as tree fruits, or other perennial cropping systems, e.g., sugar cane, where a crop is cultivated for several years in the same field ( Sumner and Beaufils, 1975 ; Raghupathi et al, 2004 ; Raj and Rao, 2006 ; Srivastava and Singh, 2008 ).…”

Ideal fertilizer management to optimize plant productivity and quality is more relevant than ever, as global food demands increase along with the rapidly growing world population. At the same time, sub-optimal or excessive use of fertilizers leads to severe environmental damage in areas of intensive crop production. The approaches of soil and plant mineral analysis are briefly compared and discussed here, and the new techniques using fast spectroscopy that offer cheap, rapid, and easy-to-use analysis of plant nutritional status are reviewed. The majority of these methods use vibrational spectroscopy, such as visual-near infrared and to a lesser extent ultraviolet and mid-infrared spectroscopy. Advantages of and problems with application of these techniques are thoroughly discussed. Spectroscopic techniques considered having major potential for plant mineral analysis, such as chlorophyll a fluorescence, X-ray fluorescence, and laser-induced breakdown spectroscopy are also described.

“…Yousef et al (2013) reported that the effectiveness of yield-limiting nutrients application was Mg <K <Ca <Fe <Zn <P < N <S <B using CND method. PCA is used on row-centered log ratios and derived nutrient indices in CND method for describing the interaction between the nutrients (Parent et al, 1994;Raghuptahi et al, 2005).…”

Plant nutrient composition of can be used as an evaluation criterion for optimum plant growth. The objectives of present study were to (a) derive critical compositional nutrient (CND) norms for survived wheat fields and sufficiency ranges as CND nutrient index for validation samples, (b) provide a squared CND threshold nutrient imbalance index (CND r2) and compare with DRIS nutrient imbalance indices, (c) determine balanced nutrients concentration with CND indices. The yield cutoff value was 4,232 kg.ha-1. The CND indexes results indicate that Zn is the most deficient nutrient in wheat, followed by Cu, Fe, Mn and B, whereas N is the most excessive nutrient, followed by K, Ca, Mg and P. In the validation trials, the yield cutoff value were reported 5.023 kg.ha-1. The calculated CND r2 in the validation population was lower than that of the survey wheat fields, indicating a more balanced concentration of nutrients due to the application of fertilizer treatments. Significant principal component (PC) loadings were obtained after the varimax rotation. The first three PCs in high- and low-yielding subgroups and whole data set indicated 52.8, 54.6 and 48.8 % total variance, respectively. This study revealed that the decline in the wheat yield was due to the nutrient imbalance associated with multi nutrient deficiency (Zn, Cu, Fe, Mn and B) and multi nutrient excess (N, K, Ca, Mg and P).
