Available in PDF, EPUB and Kindle. Book excerpt: O presente trabalho revisa os sistemas tradicionais de plantio, resultados experimentais e possibilidades para melhorar os sistemas de consorcio com os algodoes arboreo (moco e hercaceo. O algodao arboreo e consorciado no primeiro ano com culturas anuais, como milho e/ou caupi, com palma durante todo i ciclo, ou com culturas forrageiras. Embora as producoes de algodao tenham sido prejudicadas com o consorcio, a produtividade como um todo e o retorno total, exceto com gramineas forrageiras, foram maiores do que aqueles provenientes do plantio isolado. A producao de algodao arboreo nao e afetada pelo aumento do espacamento entre fileiras em ate quatro metros, ou em fileiras duplas distanciadas de tres a quatro metros. O espaco proporcionado pelo maior distanciamento entre fileiras oferece condicoes para o consorcio nao so no primeiro ano como tambem nos anos subsequentes. Portanto, sao necessarios estudos para que se conhecam as condicoes ambientais nas quais esta pratica poderia ser vantajosa. O algodao herbaceo e consorciado com milho, feijao ou com dois ao mesmo tempo. A vantagem do algodao herbaceo no plantio consorciado em relacao ao plantio isolado variou de 20 a 37%. As futuras pesquisas com a consorciacao do algodao poderiam incluir estudos sobre: a) identificacao de genotipos compativeis para o consorcio; b) definicao de niveis e metodos eficientes de adubacao, principalmente nos sistemas de plantio consorciados envolvendo o algodao herbaceo plantado em areas que tem maior precipitacao pluviometrica; (...).

This book was released on 1978 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: O algodao arboreo constitui umas das principais fontes de renda do Estado do Piaui. Seu rendimento medio e de 2l3 kg/ha e a principal area de producao esta situada na regiao centro-leste do Estado. O cultivo doalgodao arboreo consorciado com milho ou feijao, ou com essas duas culturas simultaneamente, e pratica comum entre os cotinocultores, objetivando diminuir o gastos de implantacao de algodao, que, no primeiro ano, apresenta baixo rendimento. O consorcio de algodao arboreo com culturas alimentares nao desfavorece a producao de algodao nos anos subsequentes e o rendimento economico do primeiro ano e superior a 26%, quando comparado com o da cultura algodoeira isolada. Com este trabalho objetiva-se atraves da introducao de um sistema de consorcio mais adequada elevar a receita bruta do produtor de algodao no primeiro ano de implantacao da cultura.

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.

Download or read book Nematode Interactions written by M. Wajid Khan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nematode interactions are important biological phenomena and of great significance in agriculture. It is a fascinating subject which is multidisciplinary by nature, and concerns any scientist involved with plant health. There have been marked advances in our knowledge of various aspects of the subject in the last two decades. This study area has been the subject of several reviews, but there was no exclusive text on the subject. This has stressed the need to document the information, developing a unifying theme which treated nematode interactions in a holistic manner. This book is about the inter action of plant-parasitic nematodes with other plant pathogens or root symbionts, the nature of their associations, their impact on the host and con sequential interactive effects on the involved organisms. Since nematodes are at the centre of the theme, the responsibility of understanding of other plant pathogens dealt with in this book is largely delegated to the reader. I have limited the book content to interactions with biotic pathogens and root symbionts only, for various reasons. The book embodies 16 chapters, and attempts to present balanced infor mation on various aspects of nematode interactions with other plant pathogens and root symbionts. Some chapters describe general aspects of the subject. Interactions of nematodes with specific groups of organisms are addressed in the remaining chapters.

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.

The contributors are an international group that includes 50 peanut experts from the United States, India, The Peoples Republic of China, Malawi, Australia, Israel, and South Africa. They offer advice on diseases and disorders found in each of the world's major peanut-growing regions.Detailed descriptions of 55 peanut diseases are the core of the book. Covering diseases caused by fungi, bacteria, nematodes, and viruses, these descriptions present detailed information on symptoms, causal organisms, disease cycle, control, host range, transmission, detection, and epidemiology. In addition to diseases, the compendium also describes peanut disorders caused by environmental stress, insects and arthropods, and parasitic flowering plants. Other sections of the compendium cover beneficial organisms, organisms with an undetermined relationship to peanuts, disease management strategies, genetic modification, and a listing of disease and insect resistant cultivars currently available for use by growers and breeders.
