Available in PDF, EPUB and Kindle. Book excerpt: A expansão da cultura da soja nas regiões de baixa latitude do Brasil estimulam estudos para estabelecer tecnologias e manejo adequado para seu cultivo. As recomendações de adubação devem ser relacionadas com a resposta da variedade utilizada à adubação, visando à meta do máximo retorno por área, de tal maneira a atingir o máximo retorno econômico. No Estado do Pará, a área plantada com a cultura vem crescendo, principalmente nas regiões sul, sudeste, nordeste e oeste paraense. As pesquisas com fertilidade do solo e nutrição mineral da soja são incipientes e as recomendações técnicas são adaptadas de informações obtidas em outras regiões. Desse modo o presente trabalho teve como objetivo estabelecer curvas de respostas do fósforo e potássio para a cultlura da soja. Os experimentos foram conduzidos no campo experimental da Embrapa Amazônia Oriental, nos municípios de Paragominas e Belterra, PA. Foi usada a cultivar Sambaíba como planta indicadora com espaçamento de 50 cm entre fileiras, com a densidade de 20 sementes/metro linear, num delineamento de blocos ao acaso com os tratamentos dispostos num esquema fatorial 4 x 4, com quatro repetições, correspondendo a doses de fósforo (0,80, 160,240 kg ha-1 de P2O5), na forma de superfosfato simples e quatro doses de potássio (0, 60, 120, 180 kg ha-1 de K2O), na forma de cloreto de potássio. A necessidade de calagem foi baseada na elevação da saturação por bases. A cal agem foi realizada para elevação da saturação por bases a 60%, sendo realizada 60 dias de antecedência do plantio. A adubação fosfàtada foi realizada de uma única vez no sulco de V plantio. A adubação potássica foi parcelada em duas vezes, 1/3 no plantio, 2/3 em cobertuta na época do florescimento, de acordo com os tratamentos. Foram avaliadas a produtividade, altura das plantas, peso de 100 sementes, inserção da 1 a vagem, grau de acamamento, número de dias de florescimento, umidade de grãos na época da colheita e anotações de aparecimento de pragas e doenças, além das análises química de solo e planta. A aplicação anual de 80 kg ha-1 de P2O5 e 60 kg ha-1 de K2O foi suficiente para atender à demanda da cultura da soja e manter os teores de fósforo e potássio no solo próximo do nível crítico. O aumento dos teores de potássio no solo resultam em queda na concentração de cálcio e magnésio na matéria seca da soja. O conteúdo de fósforo e potássio nas tolhas de soja cultivada em Belterra foi maior do que em Paragominas. Os nutri entes absorvidos em maiores quantidades pela soja foram o N e o K, seguindo-se, pela ordem decrescente: Ca, Mg, P e S. Em Latossolo Amarelo textura argilosa, com baixo teor de fósforo e potássio a soja cv. Sambaíba produziu 3.600 kg ha-1 de grãos, acima da média nacional, com aplicações de 80 kg ha-1 de P2O5 e 60 kg ha-1 de K2O.

No ano agricola 1978/79 (1o cultivo) os tratamentos foram instalados a partir de tres fontes fosfatadas (superfosfato triplo, termofosfato Mg-Yoorin e fosfato de Araxa) e quatro niveis (considerando-se os fatores 0,5 - 1,0 - 1,5 - 2,0 vezes o valor X, calculado pelo processo de WAUGH e FITTS, modificado por FERREIRA, aplicados a lanco e incorporados a uma profundidade de 0-20 cm. No ano agricula 1979/80 (2o cultivo) os tratamentos foram formados pelos tratamentos do primeiro cultivo (efeito residual) mais cinco niveis de adubacao fosfatada (soperfosfato triplo) em manutencao no sulco de plantio. Para avaliacao, realizou-se amostragem de solo em diferentes periodos (outubro e novembro de 1978; marco e novembro de 1979; marco de 1980) determinando-se pH, Al+3 trocavel, Ca++ + Mg++ trocaveis e P soluvel em NH4F 0,03N + Hcl 0,025N (Bray-1) e producao de graos no ano agricola de 1978/79 e ano agricola de 1979/80.

Book Synopsis Proximal Soil Sensing by : Raphael A. Viscarra Rossel
Download or read book Proximal Soil Sensing written by Raphael A. Viscarra Rossel and published by Springer Science & Business Media. This book was released on 2010-07-25 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reports on developments in Proximal Soil Sensing (PSS) and high resolution digital soil mapping. PSS has become a multidisciplinary area of study that aims to develop field-based techniques for collecting information on the soil from close by, or within, the soil. Amongst others, PSS involves the use of optical, geophysical, electrochemical, mathematical and statistical methods. This volume, suitable for undergraduate course material and postgraduate research, brings together ideas and examples from those developing and using proximal sensors and high resolution digital soil maps for applications such as precision agriculture, soil contamination, archaeology, peri-urban design and high land-value applications, where there is a particular need for high spatial resolution information. The book in particular covers soil sensor sampling, proximal soil sensor development and use, sensor calibrations, prediction methods for large data sets, applications of proximal soil sensing, and high-resolution digital soil mapping. Key themes: soil sensor sampling – soil sensor calibrations – spatial prediction methods – reflectance spectroscopy – electromagnetic induction and electrical resistivity – radar and gamma radiometrics – multi-sensor platforms – high resolution digital soil mapping - applications Raphael A.

Download or read book Lectins and Cancer written by Hans-Joachim Gabius and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular recognition undoubtedly governs any aspect of cellular interaction. To understand tumor cell growth regulation and spread, analysisof protein carbohydrate interactions can contribute to lead to the establishment of rational methods for diagnosis and therapy. Chemically and biochemically optimized preparation of adequate tools, their application for localization of receptor (tissue lectin) and ligand (cellular glycoconjugate) pairs in tumor cells and tumor sections and the usefulness of a lectin from a plant extract as potent immunomodulator indicate the prospect for a place of such techniques in pathology and oncology.

Book Synopsis Osmolytes and Plants Acclimation to Changing Environment: Emerging Omics Technologies by : Noushina Iqbal
Download or read book Osmolytes and Plants Acclimation to Changing Environment: Emerging Omics Technologies written by Noushina Iqbal and published by Springer. This book was released on 2015-12-16 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continual change in climatic conditions induces a series of adaptations in plants to suit the unfavorable conditions for sustainable agriculture. For sustainable agriculture, it is important to unravel the precise mechanism(s) that disturb the homeostatic equilibrium at cellular and molecular level and also to enhance understanding to build strategies for the tolerance of plants. Osmolytes have long been identified as pivotal abiotic stress busters because of their role in plants in overcoming extremely harsh environmental conditions. This edited compilation attempts to put forth the scattered knowledge on osmolytes and their role in abiotic stress tolerance together and disseminate as a package to deal with the problems of lower productivity under stressful environment. It will enhance the understanding on osmolytes function and bioengineering of plants for abiotic stress tolerance. The book covers very interesting topics dealing with various osmolytes and the mechanistic approach for abiotic stress tolerance to pave the path of agricultural scientists, breeders for developing high yielding sustainable transgenic crops.
