This book was released on 2001 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Com o intuito de avaliar a possibilidade de realizacao do plantio direto com a cultura do arroz de sequeiro, bem como verificar se ha resposta diferenciada das novas cultivares a esse sistema de plantio, experimentos foram conduzidos no municipio de Santa Helena de Goias (GO), Brasil, em um Latossolo vermelho escuro, de uso continuo de plantio direto ha 14 anos. Foram testadas 20 cultivares de arroz de terras altas no ano agricola 1998/99 e 25 em 1999/2000, (sendo 14 delas comuns aos dois anos), sob Plantio Direto (PD) e Plantio Convencional (PC). Utilizou-se o delineamento experimental de blocos casualizados, com quatro repeticoes. As parcelas constituiram-se de quatro linhas de 5m de comprimento, espacadas de 0,4m entre si. As variaveis avaliadas foram: produtividade de graos, altura de plantas, florescimento, acamamento e incidencia de doencas. Os resultados obtidos revelaram altas produtividades medias de graos das cultivares, que foram estatisticamente similares nos dois sistemas de plantio, nao se detectando interacao significativa entre cultivares e sistemas. A altura media das plantas das 14 cultivares, comuns aos dois anos de avaliacao, foi estatisticamente superior no PC (101,0 cm) em comparacao com o PD (98,8 cm), ou seja, o PD foi menos favoravel ao desenvolvimento das plantas, o que induziu tambem, um atraso aproximado de cinco dias no florescimento. Por outro lado, houve uma tendencia de maior incidencia de doencas nas plantas cultivadas sob PC. Observou-se ainda, que os sistemas de plantio nao influiram na ocorrencia de acamamento. Os resultados obtidos permitem concluir que o sistema de plantio direto e viavel para o arroz de terras altas, cultivar nao e fator limitante e que as cultivares atualmente disponiveis comportam-se de modo semelhante quanto a produtividade de graos nos dois sistemas de plantio.

Book Synopsis The Physiology of Vegetable Crops, 2nd Edition by : Hans Christian Wien
Download or read book The Physiology of Vegetable Crops, 2nd Edition written by Hans Christian Wien and published by CABI. This book was released on 2020-05-01 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Completely updated and revised, this bestselling book continues to explain the growth and developmental processes involved in the formation of vegetables. Since the publication of the successful first edition significant discoveries, particularly in the area of molecular biology, have deepened and broadened our knowledge and understanding of these processes. This new edition brings the topic up-to-date and is presented over two sections: the first provides general knowledge on germination, transplanting, flowering, the effects of stress and modelling, whilst the second section details the physiology of specific crops or crop groups.

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.

This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phytomass and Primary Production of the Various Vegetational Zones and of the Entire Biosphere The biosphere is that thin layer at the earth's surface in which living organisms exist and biological cycling takes place. It includes the upper horizons of the soil in which plants root, the atmosphere near the ground, (insofar as organisms penetrate this space), and all the surface waters. More than 99% of the earth's biomass is phytomass, to which we shall limit our discussion. Amounts of phytomass are distinctly related to vegeta tional zones. Because accurate determination of phytomass and primary production is difficult, only gross estimates have been available until recently. However, in 1970, Bazilevich et al. published (in Russian) more accurate calculations, based on the rapidly accumulating literature, for the various thermal zones and bioclimatic regions of the earth. These authors calculated mean phyto mass and mean annual primary production for the various regions as dry mass (in tons) per hectare. On the basis of measurements of the areas covered by the individual regions, excluding rivers, lakes, glaciers, and permanent snow, total phytomass and total annual primary production for the various regions were obtained (see table). The sum of these figures is the phytomass and annual production of the land surface of the earth. In addition, the table gives corresponding data for the waters of the earth. The values involved are potential i. e. , they are based on natural vegetation uninfluenced by man.
Book Synopsis Climate Dynamics of the Tropics by : S. Hastenrath
Download or read book Climate Dynamics of the Tropics written by S. Hastenrath and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of my book "Climate and Circulation of the Tropics" was reasonably up to date to the middle of 1985. In a second printing in 1988 it was possible to complete a few literature references and to correct some misprints. However, vigorous research has taken place over the past five years in various areas of tropical climate dynamics, especially in the atmosphere-ocean mechanisms of climate anomalies, climate prediction, ocean circulation, and paleoclimates. Promising progress has also been made in the application of general circulation modelling to tropical climate problems. In the present second edition, named "Climate Dynamics of the Tropics", I have attempted to incorporate much of the recent work to late 1990. Chapters 8 and 9 have been essentially re-written, and major additions have been made to Chapters 4 and 12 in particular. I would like to acknowledge the continued support by the U.S. National Science Foundation over the past five years. B. Parthasarathy, Poona, and H. Lessmann, San Salvador, sent me updates of data series not easily accessible. I have benefitted from discussions with numerous colleagues in the United States and overseas. In the preparation of this second edition, Marilyn Wolff patiently transferred my illegible hand-written drafts onto word processor. Dierk Polzin and Dan Skemp assisted me with the creation of the page masters and the subject index and Christopher Collimore with the author index.
