Book Synopsis Períodos de controle de plantas daninhas na cultura do milho (Zea mays L.). Efeito do número de repetições sobre a precisão experimental by : V. de PALMA

Efeito do número de repetições sobre a precisão experimental written by V. de PALMA and published by . This book was released on 2000 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foi conduzido um experimento com o objetivo de determinar o minimo de repeticoes para que niveis pre-estabelecidos de precisao sejam alcancados; e avaliar a matointerferencia na cultura do milho determinando a duracao do periodo que antecede a interferencia e do periodo total de prevencao de interferencia da comunidade infestante sobre a produtividade da cultura. A cultura do milho foi mantida na presenca ou na ausencia das plantas daninhas ate 0, 10, 20, 30, 40, 50, 60 e 120 dias apos a emergencia. O experimento foi conduzido no periodo de dezembro de 1997 a abril de 1998, correspondendo a safra de verao, na Fazenda Experimental "Marcelo Mesquita Serva" na Universidade de Marilia-UNIMAR, localizada no municipio de Marilia, Estado de Sao Paulo-Brasil. A precisao das combinacoes de repeticoes, avaliada pela diferenca minima significativa (dms), mostrou-se continuamente crescente com a adicao de novas repeticoes, observando-se, contrudo, reducoes menores acima de seis repeticoes. Os valores medios do quadrado medio do residuo (QMR), coeficiente de variacao (CV) e o F dos tratamentos nao foram alterados pelo aumento do numero de repeticoes. Nos trtamentos com periodos inicais sem controle, o maximo crescimento da comunidade infestante foi observado entre 20 e 30 dias apos a emergencia da cultura. O controle de plantas daninhas no periodo de 0-40 dias apos a emergencia da cultura, foi suficiente para minimizar a porcentagem de cobertura de plantas daninhas presentes na avaliacao realizada no final do ciclo do milho. Os valores obtidos para o periodo que antecede a interferencia (PAI) e para o periodo total de prevencao de interferencias (PTPI) foram influenciados pelo tipo de analise estatistica e pelo rigor adotados, na sua determinacao. A duracao do periodo de total de prevencao de interferencia (PTPI) foi 37 dias contados a partir da emergencia do milho. A duracao do periodo que antecede as interferencias (PAI) foi de 21 dias contados a partir da emergencia do milho. A duracao do periodo critico de prevencao de interferencia (PCPI) que corresponde a fase em que as praticas de controle deveriam ser efetivamente adotadas foi no periodo de 21 a 37 dias. O peso medio da espiga foi o componente da producao mais sensivel a matointerferencia.

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. Viscarra Rossel is a scientist at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) of Australia. Alex McBratney is Pro-Dean and Professor of Soil Science in the Faculty of Agriculture Food & Natural Resources at the University of Sydney in Australia.

Book Synopsis The Ritual Process by : Victor Turner
Download or read book The Ritual Process written by Victor Turner and published by Routledge. This book was released on 2017-07-05 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Ritual Process: Structure and Anti-Structure, Victor Turner examines rituals of the Ndembu in Zambia and develops his now-famous concept of "Communitas." He characterizes it as an absolute inter-human relation beyond any form of structure.The Ritual Process has acquired the status of a small classic since these lectures were first published in 1969. Turner demonstrates how the analysis of ritual behavior and symbolism may be used as a key to understanding social structure and processes. He extends Van Gennep's notion of the "liminal phase" of rites of passage to a more general level, and applies it to gain understanding of a wide range of social phenomena. Once thought to be the "vestigial" organs of social conservatism, rituals are now seen as arenas in which social change may emerge and be absorbed into social practice.As Roger Abrahams writes in his foreword to the revised edition: "Turner argued from specific field data. His special eloquence resided in his ability to lay open a sub-Saharan African system of belief and practice in terms that took the reader beyond the exotic features of the group among whom he carried out his fieldwork, translating his experience into the terms of contemporary Western perceptions. Reflecting Turner's range of intellectual interests, the book emerged as exceptional and eccentric in many ways: yet it achieved its place within the intellectual world because it so successfully synthesized continental theory with the practices of ethnographic reports."

Book Synopsis Agriculture and Industry in Brazil by : Albert Fishlow
Download or read book Agriculture and Industry in Brazil written by Albert Fishlow and published by Columbia University Press. This book was released on 2020-08-04 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture and Industry in Brazil is a study of the economics of Brazilian agriculture and industry, with a special focus on the importance of innovation to productivity growth. Albert Fishlow and José Eustáquio Ribeiro Vieira Filho examine technological change in Brazil, highlighting the role of public policy in building institutions and creating an innovation-oriented environment. Fishlow and Vieira Filho tackle the theme of innovation from various angles. They contrast the relationship between state involvement and the private sector in key parts of the Brazilian economy and compare agricultural expansion with growth in the oil and aviation sectors. Fishlow and Vieira Filho argue that modern agriculture is a knowledge-intensive industry and its success in Brazil stems from public institution building. They demonstrate how research has played a key role in productivity growth, showing how prudent innovation policies can leverage knowledge not only within a particular company but also across whole sectors of the economy. The book discusses whether and how Brazil can serve as a model for other middle-income countries eager to achieve higher growth and a more egalitarian distribution of income. An important contribution to comparative, international, and development economics, Agriculture and Industry in Brazil shows how the public success in agriculture became a prototype for advance elsewhere.
Book Synopsis The Root Causes of Biodiversity Loss by : Alexander Wood
Download or read book The Root Causes of Biodiversity Loss written by Alexander Wood and published by Routledge. This book was released on 2013-11-05 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world is losing species and biodiversity at an unprecedented rate. The causes go deep and the losses are driven by a complex array of social, economic, political and biological factors at different levels. Immediate causes such as over-harvesting, pollution and habitat change have been well studied, but the socioeconomic factors driving people to degrade their environment are less well understood. This book examines the underlying causes. It provides analyses of a range of case studies from Brazil, Cameroon, China, Danube River Basin, India, Mexico, Pakistan, Philippines, Tanzania and Vietnam, and integrates them into a new and interdisciplinary framework for understanding what is happening. From these results, the editors are able to derive policy conclusions and recommendations for operational and institutional approaches to address the root causes and reverse the current trends. It makes a contribution to the understanding of all those - from ecologists and conservationists to economists and policy makers - working on one of the major challenges we face.
