Book Synopsis Controle Integrado de Plantas Infestantes Na Cultura Do Milho by : L. H. Martins
Download or read book Controle Integrado de Plantas Infestantes Na Cultura Do Milho written by L. H. Martins and published by . This book was released on 2000 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dentre os fatores que contribuem para a baixa produtividade da cultura do milho no Brasil, destaca-se a competição exercida pelas plantas daninhas, que reduz a produção econômica, aumenta os custos de produção, reduzindo a lucratividade. Os objetivos deste trabalho foram: i) determinar o sistema de controle de plantas daninhas mais adequado; ii) quantificar a interferência das plantas daninhas na cultura do milho; iii) avaliar a eficácia agronômica e praticabilidade de herbicidas, para uso nos sistemas de produção de milho; iv) obter subsídios para oferecer recomendações de novas tecnologias para o controle das plantas daninhas. Os experimentos, em delineamento de blocos ao acaso, foram constituídos de dez tratamentos com quatro repetições, conduzidos na Estação Experimental da Empam em Ipanguaçu-RN, nos anos de 1997 e 1998. Foram testados quatro tratamentos com herbicidas de pós-emergência: dois em área total e dois em faixa de 40 cm complementados com cultivo de tração animal, sendo dois com atrazine + metolachlor + óleo e dois com nicosulfuron. Dois tratamentos de pré-emergência com atrazine + metolachlor: um em área total e um em faixa de 40 cm complementado com cultivo de tração animal. Dois tratamentos de cultivo com tração animal com e sem repasse de enxada e duas testemunhas, com capina e sem capina Os herbicidas foram aplicados com aparelho de pulverização pressurizado com CO2, com barra de quatro bicos e volume de aplicação de 250 l/ha. Foi usada a cultivar de milho Cruzeta (BR 5037) na densidade de 55.000 plantas por hectare. Os tratamentos com a mistura atrazine + metolachlor apresentaram boa eficiência no controle das plantas daninhas. Os métodos tradicionais de controle, como o cultivo mecânico com repasse, ainda são perfeitamente viáveis. A integração dos sistemas de controles químico e mecânico se constitui numa alternativa vantajosa para o controle das plantas daninhas, por aumentar a eficiência de controle, diminuir o volume de herbicidas aplicado reduzindo os custos e também os riscos de contaminação do meio ambiente. Nenhum dos tratamentos foi eficaz no controle da espécie Cyperus rotundus devido a sua grande ocorrência e resistência a herbicidas. A interferência das plantas daninhas no rendimento da cultura do milho foi de 68,5 %.

Book Synopsis Pest Management in Soybean by : L.G. Copping
Download or read book Pest Management in Soybean written by L.G. Copping and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the third in a series of volumes on major tropical and sub-tropical crops. These books aim to review the current state of the art in management of the total spectrum of pests and diseases which affect these crops in each major growing area using a multi-disciplinary approach. Soybean is economically the most important legume in the world. It is nutritious and easily digested, and is one of the richest and cheapest sources of protein. It is currently vital for the sustenance of many people and it will play an integral role in any future attempts to relieve world hunger. Soybean seed contains about 17% of oil and about 63% of meal, half of which is protein. Modern research has developed a variety of uses for soybean oil. It is processed into margarine, shortening, mayonnaise, salad creams and vegetarian cheeses. Industrially it is used in resins, plastics, paints, adhesives, fertilisers, sizing for cloth, linoleum backing, fire extinguishing materials, printing inks and a variety of other products. Soybean meal is a high-protein meat substitute and is used in the developed countries in many processed foods, including baby foods, but mainly as a feed for livestock. Soybean (Glycine max), which evolved from Glycine ussuriensis, a wild legume native to northern China, has been known and used in China since the eleventh century Be. It was introduced into Europe in the eighteenth century and into the United States in 1804 as an ornamental garden plant in Philadelphia.

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.
