Download or read book Nitrogen fertilization in bean plant cv. BRS-MG Talismã in no tillage and conventional crop system written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: O nitrogênio é o nutriente mais exigido pelo feijoeiro e, considerando-se altas produtividades, são necessárias quantidades expressivas de N, o que torna a adubação nitrogenada indispensável. O objetivo deste trabalho foi avaliar, a campo, a resposta do feijoeiro cv. BRS-MG Talismã, a doses crescentes de nitrogênio por ocasião da semeadura e/ou cobertura. Para estudo da adubação nitrogenada de plantio foram conduzidos sete experimentos em plantio convencional, um em plantio direto, em diferentes safras de 2002 e 2003. O delineamento estatístico foi blocos casualizados com cinco repetições e seis tratamentos (0, 30, 60, 90, 120 e 150 kg.ha-1 de N, fonte uréia) aplicados em dose única por ocasião da semeadura. Para estudo da adubação nitrogenada de cobertura foram instalados quatro experimentos de campo em Madre de Deus de Minas e São Vicente de Minas. Na seca 2004, o delineamento estatístico utilizado foi blocos casualizados, com dez repetições e cinco doses de N em cobertura, aplicados aos 20 DAE (0, 30, 60, 90 e 130 kg ha-1). Nos demais ensaios foi utilizado o mesmo delineamento com seis repetições e 4 doses de N em cobertura (0, 40, 80 e 120 kg ha-1). Para o estudo da interação adubação nitrogenada de plantio x cobertura foram conduzidos dois experimentos (plantio direto e convencional), na safra das águas 2004/05. O delineamento estatístico foi blocos casualizados com três repetições e esquema fatorial 4x4 envolvendo 4 doses de N no plantio (0, 40, 80 e 120 kg.ha-1) e 4 doses de N em cobertura (0, 40, 80 e 120 kg.ha-1) aos 20 DAE. Cada parcela foi constituída por quatro linhas de 5 m de comprimento, com espaçamento de 0,5 m e densidade de 15 sementes.m-1. O primeiro grupo de experimentos permitiu constatar que em ambientes mais favoráveis para o feijoeiro, como no inverno irrigado, o incremento da dose de N no plantio eleva o número de vagens por planta e, consequentemente, o rendimento de grãos do feijoeiro, até um ponto máximo, em torno de 57 kg.ha-1 de N.A partir deste ponto, a contínua redução da população de plantas pelo efeito salino do fertilizante nitrogenado reduz a produtividade, limitando a possibilidade do emprego de doses elevadas de N no plantio. Em condições de excessiva precipitação pluvial, como na safra das águas, ou de outro fator limitante, o efeito das doses crescentes de N no plantio sobre estande final e rendimento de grãos é reduzido. O segundo grupo de experimentos permitiu concluir que no plantio convencional a resposta à aplicação de N em cobertura foi quadrática e a dose correspondente à máxima produtividade variou com o ambiente. O plantio convencional apresentou menor amplitude de rendimento de grãos entre os ambientes e maior estande final, entretanto, no plantio direto o rendimento de grãos foi superior. No plantio direto não houve resposta à aplicação de N em cobertura (seca 2004) ou essa resposta foi linear crescente. No terceiro grupo de experimentos concluiu-se que, em ambos os sistemas de plantio, o incremento do fertilizante nitrogenado de plantio reduziu o estande de plantas. De maneira geral, no plantio direto a resposta à aplicação de N no plantio foi quadrática e a dose correspondente à máxima produtividade variou com as doses de cobertura. No plantio convencional essa resposta foi linear decrescente, devido ao maior efeito do N de plantio sobre o estande. A resposta à aplicação de N em cobertura foi quadrática, em ambos s sistemas de plantio e as maiores respostas do rendimento de grãos foram observadas com o emprego da dose de 40 kg.ha-1 de N no plantio.

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.

Book Synopsis Biochar for Environmental Management by : Dr. Johannes Lehmann
Download or read book Biochar for Environmental Management written by Dr. Johannes Lehmann and published by Earthscan. This book was released on 2009 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Biochar is the carbon-rich product when biomass (such as wood, manure, or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process.This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines"--Provided by publisher.
