Book Synopsis Cultura antecessora e adubação nitrogenada na produção do milho em um sistema de plantio direto by : D. A. da SILVA
Download or read book Cultura antecessora e adubação nitrogenada na produção do milho em um sistema de plantio direto written by D. A. da SILVA and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A utilização de espécies antecessoras ao milho com capacidade de fixação simbiótica de nitrogênio e/ou reciclagem deste nutriente é de grande importância para a manutenção da produtividade e redução de custos. Com o objetivo de avaliar o efeito de culturas antecessoras associadas a doses de nitrogênio no desempenho agronômico do milho, desenvolveu-se este trabalho no município de Dourados-MS no ano agrícola de 2001/02, nas dependências do Núcleo de Ciências Agrárias da Universidade Federal de Mato Grosso do Sul. O delineamento experimetal utilizado foi blocos casualisados com seis repetições em parcela sub-dividida. A parcela principal foi composta por três culturas antecessoras ao milho: aveia preta (Avena strigosa), nabo forrageiro (Raphanus sativus var. oleiferus) e ervilhaca peluda (Vicia villosa). A subparcela foi composta por seis doses de nitrogênio em cobertura - zero, 50, 100, 150, 200 e 250 kg ha a menos um. O milho cultivado após aveia preta responde positivamente à adubação nitrogenada, com máxima eficiência técnica e econômica nas doses de 205 e 150 kg ha a menos um respectivamente. Após nabo forrageiro também há respostas à adubação nitrogenada, porém pode-se utilizar menores doses para obter-se a máxima eficiência técnica e econômica (175 e 40 kg ha a menos um respectivamente). Milho cultivado após ervilhaca peluda em plantio direto não responde à adubação nitrogenada, porém, tem produtividade maior do que nas sucessões aveia preta/milho e nabo forrageiro/milho, quando a adubação nitrogenada não é utilizada.

This book was released on 1971 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: O presente trabalho foi realizado no ano agricola de 1970/71, em terrenos da Universidade Federal de Vicosa. Seu objetivo foi verificar os efeitos de diferentes fontes, doses e epocas de aplicacao de adubos nitrogenados, na cultura do feijao, nas duas epocas normais de plantio. Em solo franco-argiloso-arenoso de fertilidade media, com 0,16% de N total, foi instalado, em cada epoca normal de plantio, um experimento para estudar os efeitos de fontes e epocas de aplicacao dos fertilizantes azotados. Foram aplicados os adubos sulfato de amonio, salitre-do-Chile e ureia, na dosagem de 60 kg/ha de nitrogenio. A area experimental recebera, cerca de um mes antes do plantio, 1 t/ha de calcario dolomitico e, por ocasiao do plantio, uma adubacao uniforme de 500 kg/ha de superfosfato simples e 60 gk de cloreto de potassio. Os adubos nitrogenados foram aplicados de tres modos: metade da dose no plantio e metade 10 dias apos a emergencia dos feijoeiros;1/3 no plantio, 1/3 10 dias apos a emergencia e 1/3 25 dias apos a emergencia; nada no plantio, metade 10 dias depois da emergencia e metade 25 dias depois. Em solos franco-argilosos de fertilidade media, com 0,12 a 0,16% de N, foram instalados outros dois experimentos para estudar os efeitos de fontes e doses dos fertilizantes azotados, na cultura do feijao. Foram empregados os adubos sulfato de amonio, salitre-do-Chile, ureia, cloreto de amonio e fosfato diamonico. A calagem foi efetuada apenas no experimento do plantio da "seca", na base de 1 t/ha de calcario dolomitico. (...).

Em dois experimentos o N foi aplicado na semeadura, nas doses 0 e 60 kg ha-1 de N, e em cobertura, e em doses que complementassem um total de 0,60, 120 e 180 kg ha-1 de N. Em dez experimentos estudou-se a pliação do N em quatro doses de cobertura (0 a 180 kg ha-1) subdivididas em duas vezes. (continua).
Book Synopsis Efeito residual do calcário para o milho sob plantio direto e convencional em solo de Cerrado by : Leo Nobre de Miranda
Download or read book Efeito residual do calcário para o milho sob plantio direto e convencional em solo de Cerrado written by Leo Nobre de Miranda and published by . This book was released on 2007 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Os solos de Cerrado caracterizam-se pela alta acidez e pela presença de alumínio em níveis tóxicos, por isso é necessário aplicar calcário para que se possa obter boas produtividades das culturas nos sistemas de plantio convencional e direto. Têm sido obtidas respostas acentuadas de várias culturas à calagem, que pode ser efetuada incorporando o calcário ao solo, ou deixando-o na superfície. Observou-se que, nas doses recomendadas, o calcário incorporado pode ter efeito residual prolongando no solo, mantendo as condições adequadas para crescimento de plantas sob plantio convencional, or um período mínimo de 4 a 5 anos de cultivos sucessivos. Entretanto, essa informação ainda é escassa para o cultivo de plantas sob plantio direto.

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.

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.

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.

Download or read book Plant Nematology, 3rd Edition written by Roland N. Perry and published by CABI. This book was released on 2024-07-12 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant-parasitic nematodes are a major threat to crop production in all countries, and identification of nematodes and knowledge of their biology is of paramount importance. Providing a broad introduction to nematodes as plant parasites, this book begins by describing nematodes by genera, and then builds on this foundation to detail nematode biology and pest management, including resistance, and biological and chemical control. This 3rd edition is updated to address advances in our knowledge of plant-parasitic nematodes, particularly concerning the molecular aspects of host-parasite relationships, including the application of genomics to nematode biology. Changes in control and management strategies are also covered. The influence of climate change on plant-parasitic nematodes is addressed in a new chapter on ecology. Primarily aimed at students (MSc and PhD), this book is also invaluable for researchers and lecturers in nematology, plant pathology and parasitology, advisory and quarantine services, and crop protection scientists.

Book Synopsis Soil Quality for Crop Production and Ecosystem Health by : E.G. Gregorich
Download or read book Soil Quality for Crop Production and Ecosystem Health written by E.G. Gregorich and published by Elsevier. This book was released on 1997-11-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.
