L. e SILVA and published by . This book was released on 1976 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Em ensaio experimental, realizado na Universidade Federal de Vicosa, Minas Gerais, estudou-se o comportamento de variedades e selecoes de arroz, de diferentes tipos de planta, sob condicoes de irrigacao por submersao, e em diferentes niveis de nitrogenio. Utilizou-se esquema de parcelas subdivididas disposto no delineamento experimental de blocos casualizados, aplicando-se os niveis de 0,45 e 90 kg de N/ha nas parcelas e distribuindo-se, nas subparcelas, as seguintes variedades e selecoes: IAC-435, de porte alto, pouco perfilhamento, e folhas relativamente curtas; De Abril, porto alto, elevado perfilhamento, e folhas longas e pendentes; CICA 4, IR634-9-5-4, IR661-1-140-3 e IR665-4-1 todas com baixa estatura, perfilhamento abundante e folhas curtas e eretas. Umterco do nitrogenio foi aplicado por ocasiao do transplante e a quantidade restante, em cobertura, no inicio da diferenciacao floral. Verificou-se que, com excecao da variedade De Abril, todas as variedades e selecoes responderam, ao nitrogenio, em termos de producao de graos. Entre as variedades que apresentaram aumentos de producao de graos nao houve diferenca, quanto a esta caracteristica, em nenhum dos niveis estudados. Todas estas variedades e selecoes, todavia, diferiram da variedade De Abril, quando foram aplicados ao solo 90 kg de N/ha ...

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.

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 Animal Suffering by : Marian Dawkins
Download or read book Animal Suffering written by Marian Dawkins and published by Springer. This book was released on 1980-11-20 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: I wrote this book because I believe that the welfare of animals is a very important subject but one about which there is a of confusion and muddled thinking. I wanted to great deal write a book which straightened out some of the confusion by looking in detail at one particular problem: how to recognize animal suffering. The book is written for anyone interested in animals and the controversies over how human beings should treat them. I have tried to convince people who might otherwise feel that science had only a rather sinister connection with animal welfare that the scientific study of animal suffering has, in fact, a major and positive contribution to make. It can give us an insight into what animals experience and this, in tum, may help us to alleviate their suffering. At the same time, I have tried to write a book that will be of at least some use to scientists. The chapters which follow pro vide an outline of the biological approach to animal welfare. I have also attempted to show sceptics that it is possible to study animal suffering without sacrificing standards of scien tific procedure. Perhaps some may even come to share my belief that the study of the subjective experiences of animals is one of the most fascinating areas in the whole of biology, as well as being of great practical and ethical importance.
