Tambem foram analisados os efeitos da vazao e da declividade dos sulcos sobre a eficiencia de irrigacao, com e sem reducao da vazao inicial. Para estimar os parametros das equacoes de infiltracao e avanco da agua no sulco, foram realizados testes em areas (parcelas de colonos) selecionados no PIB e na Estacao Experimental de Bebedouro. Na selecao das areas observaram-se dois criterior basicos: primeiro, em cada parcela escolhida deveria estar sendo cultivado tomate, melao, melancia, visto serem estas culturas de maior importancia economica do PIB. As parcelas tambem deveriam, conforme o segundo criterio, estar localizadas nas unidades de solo, mais repressentativas do PIB, no casa 37AA, 37AB e 37BB.

Selecionou-se a cultura do feijao caupi (vigna sinensis) por ser uma cultura base neste periodo. Em cada lote, fez-se tres coletas de dados ao longo do ciclo fenologico do feijao, assim descriminadas: a primeira, em outubro(durante o estagio inicial do feijao) a segunda, em novembro(inicio da floracao) e a terceira, em dezembro (final do ciclo). Constatou-se que as vazoes medias obtidas nas unidades 37 AA e 37 BB foram em geral maiores que as maximas nÆo erosivas, porem menores que a maxima nao erosiva na unidade 37 AB. As declividades dos sulcos variam de 0,33 a 1,30%. A maior eficiencia de aplicacao(53,52%) foi alcancada na unidade 37 AB com 0,33% de declividade. Na unidade 37 BB com declividade de 0,9 e 1,3%, as eficiencias de aplicacao foram de 33,10 e 25,68%, respectivamente.

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.

Download or read book Agro-Ecological Intensification of Agricultural Systems in the African Highlands written by Bernard Vanlauwe and published by Routledge. This book was released on 2013-12-17 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is an urgent need to increase agricultural productivity in sub-Saharan Africa in a sustainable and economically-viable manner. Transforming risk-averse smallholders into business-oriented producers that invest in producing surplus food for sale provides a formidable challenge, both from a technological and socio-political perspective. This book addresses the issue of agricultural intensification in the humid highland areas of Africa – regions with relatively good agricultural potential, but where the scarce land resources are increasingly under pressure from the growing population and from climate change. In addition to introductory and synthesis chapters, the book focuses on four themes: system components required for agricultural intensification; the integration of components at the system level; drivers for adoption of technologies towards intensification; and the dissemination of complex knowledge. It provides case studies of improved crop and soil management for staple crops such as cassava and bananas, as well as examples of how the livelihoods of rural people can be improved. The book provides a valuable resource for researchers, development actors, students and policy makers in agricultural systems and economics and in international development. It highlights and addresses key challenges and opportunities that exist for sustainable agricultural intensification in the humid highlands of sub-Saharan Africa.
