“…The Butters-Chanery method was a modified by using an aqueous solution of BaCl 2 (instead of solid BaCl 2 ) and a surfactant stabilizer of the suspension formed in the presence of HCl (Bielecki and Kulczycki 2012 ). The results concerning macronutrient content together with the productivity data (dry mass) were used to calculate the accumulation of macronutrients in roots and shoots (Melo et al 2013 ).…”

This study evaluated the possibility of improving the macronutrient status of Cd-stressed white mustard ‘Rota’ using intensive S nutrition. Three S-SO4 (2, 6, 9 mM S) and four CdCl2 doses (0, 0.0002, 0.02, 0.04 mM Cd) in the Hoagland’s nutrient solution were conducted for 14 days. High S supply (6 or 9 mM) appears, to some extent, to affect positively the macronutrient status of Cd-stressed mustard. It increased roots and shoots contents of K and S, without significant changes in P content. Simultaneously, Mg content in shoots and roots remained stable, but Mg bioaccumulation was elevated. Shoot Ca content at the lowest and medium Cd dose decreased, whilst was unaffected at the highest Cd treatment. Intensive S nutrition of Cd-stressed mustard increased root N content and accumulation at the highest Cd concentration, but the N content dropped in above-ground parts. The bioaccumulation of remained macronutrients in general was substantially elevated together with enhanced Cd accumulation. Thus, the intensive S nutrition can enhance mustard tolerance to Cd stress by improvement macronutrients relations in plants, and S supplementation may be recommended for mustard cultivation on the Cd-contaminated areas.

“…Estas informações podem ser obtidas através do estudo da marcha de acumulação de nutrientes, em função dos estádios fenológicos da cultura, pois a capacidade de acumulação e, ou extração de nutrientes depende da produtividade obtida e da acumulação de nutrientes nos frutos e outras partes da planta (Marschner 2012). A extração de nutrientes pelo meloeiro foi pesquisada por Gurgel et al (2010), Damasceno et al (2012) e Melo et al (2013).…”

“…Gurgel et al (2010) realizaram trabalho semelhante com a variedade Goldex e observaram extrações de 134 kg de N, 25 kg de P, 130 kg de K, 150 kg de Ca 8 kg de Mg. As extrações dos micronutrientes Cu, Fe, Mn e Zn, encontradas neste mesmo trabalho, em g/ha foram de 459, 713, 765 e 137, respectivamente. Melo et al (2013) por meio de estudo de marcha de absorção de nutrientes no meloeiro rendilhado 'Fantasy' observaram que a cultura extraiu em um hectare 117 kg de N, 18 kg de P, 58 kg de K, 115 kg de Ca, 13 kg de Mg e12 kg de S. Diante disso, objetivou-se com este trabalho determinar a extração de macro e de micronutrientes pelas partes vegetativas e reprodutivas do melão amarelo 'Goldex'.…”

RESUMONo presente trabalho objetivou-se determinar a marcha de acumulação de macro e de micronutrientes cultivado sob fertirrigação. O experimento foi realizado em área pertencente à Empresa Ecofértil Brazilian Journal of DevelopmentBraz. 12655Agropecuária LTDA localizada no município de Aracati (CE). O experimento foi instalado em delineamento de blocos casualizados com 9 tratamentos, correspondentes a 9 períodos de avaliação 14, 21, 28, 35, 42, 49, 56, 63, 70 dias após transplantio com quatro repetições. Em intervalos de sete em sete dias, as plantas foram coletadas e separadas em folha, caule, fruto e semente para fins da determinação de N, P, K, Ca, Mg, S, Fe, Mn, B, Zn e Cu, para a quantificação dos totais acumulados destes nutrientes. Na ocasião da coleta de planta, uma amostra de solo foi coletada em cada parcela para a determinação dos nutrientes. De acordo com os resultados, o acúmulo de massa seca nas partes reprodutivas foi maior que nas partes vegetativas, sendo os frutos os órgãos de maior acúmulo de massa seca. Já a marcha de acúmulo de nutrientes seguiu a seguinte ordem:K>Ca>N>Mg>P>S>Fe>Cu>B>Zn>Mn. Palavras-chave:Cucumis melo L., nutrição mineral, melão amarelo, acúmulo de massa seca. ABSTRACTThe objective of this study was to determine the progression of macro and micronutrients accumulation of the melon cultivated under fertirrigation. The experiment was carried out in an area belonging to the Company Ecofértil Agropecuária Ltda located in the city of Aracati (CE). The experiment was carried out in a randomized block design with 9 treatments, corresponding to 9 evaluation periods 14, 21, 28, 35, 42, 49, 56, 63, 70 days after transplanting (DAT) with four replications. The useful part for the purpose of collection was constituted of 8 plants becoming the four centers of each row. At intervals of seven days, the plants were collected and separated into leaf, stem, fruit and seed for the determination of N, P, K, Ca, Mg, S, Fe, Mn, B, Zn and Cu, for The quantification of accumulated totals of these nutrients. At the time of plant collection, a soil sample was collected in each plot to determine the nutrients. According to the results, the accumulation of dry mass in the reproductive parts was higher than in the vegetative parts, the fruits being the organs

“…Os nutrientes mais exigidos pelo melão são o N, K e Ca, que, dependendo da variedade, podem ocupar diferentes posições entre si em termos quantidades extraídas pela cultura. Gurgel et al (2010) Melo et al (2013) por meio de estudo de marcha de absorção de nutrientes no meloeiro rendilhado 'Fantasy' observaram que a cultura extraiu em um hectare 117 kg de N, 18 kg de P, 58 kg de K, 115 kg de Ca, 13 kg de Mg e12 kg de S.…”
