This book was released on 2000 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Desde 1980, a pesquisa tem mostrado a inutilidade da prática da adubação nitrogenada na semeadura da soja. Entretanto, com a expansão do plantio direto, na região do Cerrado, novamente surgiram dúvidas, por parte de alguns agricultores, sobre a eficiência do processo de inoculação e sobre a necessidade, ou não, da utilização de doses de "arranque" de adubo nitrogenado na semeadura, para superar possíveis problemas relacionados a imobilização do N e a competição inicial com plantas invasoras. Foram conduzidos, na Embrapa Cerrados, dois experimentos em áreas sob plantio direto (PD) e dois em áreas sob plantio convencional (PC) para avaliar a resposta da soja a pequenas doses de N na semeadura. Os tratamentos consistiram de quatro níveis de N (0, 20, 30, e 40 kg N.ha-1) na forma de uréia, aplicada, na semeadura, no sulco de plantio. Em ambas as áreas, a soja foi cultivada apos o milho. Todos os tratamentos foram inoculados com as estirpes SEMIA 5079 (CPAC 15) e SEMIA 5080 (CPAC 7) na proporção de 1 kg de inoculante para 50 kg de sementes. A adição de pequenas doses de adubo nitrogenado, na semeadura da soja, promoveu reduções significativas de ate 50% na sua nodulação inicial, avaliada aos 15 dias após a emergência. Apesar dessa redução, houve recuperação no número e na massa de nodulos na fase da floração. Independentemente do sistema de manejo, a adição de pequenas doses de N, na semeadura, não promoveu aumentos no rendimento de grãos da soja. Os resultados confirmam que não e necessário adicionar fertilizante nitrogenado na semeadura da soja.

Download or read book Nitrogen Fixation in Agriculture, Forestry, Ecology, and the Environment written by Dietrich Werner and published by Springer Science & Business Media. This book was released on 2006-01-20 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainability has a major part to play in the global challenge of continued development of regions, countries, and continents all around the World and biological nitrogen fixation has a key role in this process. This volume begins with chapters specifically addressing crops of major global importance, such as soybeans, rice, and sugar cane. It continues with a second important focus, agroforestry, and describes the use and promise of both legume trees with their rhizobial symbionts and other nitrogen-fixing trees with their actinorhizal colonization. An over-arching theme of all chapters is the interaction of the plants and trees with microbes and this theme allows other aspects of soil microbiology, such as interactions with arbuscular mycorrhizal fungi and the impact of soil-stress factors on biological nitrogen fixation, to be addressed. Furthermore, a link to basic science occurs through the inclusion of chapters describing the biogeochemically important nitrogen cycle and its key relationships among nitrogen fixation, nitrification, and denitrification. The volume then provides an up-to-date view of the production of microbial inocula, especially those for legume crops.

This book was released on 1974 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neste trabalho, realizado em tres localidades de Minas Gerais, no ano agricola de 1973/74, procurou-se estudar em soja (Glycine max (L.) Merril), inoculada com Rhizobium japonicum, a variacao de nitrogenio e enxofre nas folhas aos 40 e 50 dias apos o plantio, relacionados com os niveis de nitrogenio aplicados ao solo, assim como a possibilidade de suprir as necessidades de nitrogenio da soja a aplicacao de fertilizantes nitrogenados, e ainda verificar a relacao entre producao de graos e os teores de nitrogenio nas folhas. Em Vicosa, o ensaio foi montado em Podzolico Vermelho Amarelo Cambio, fase terraco, usando a variedade "UFV-1". Em Capinopolis e Lavras, a variedade foi a "IAC-2" e os solos se classificaram em Latossol Roxo e Latossol Vermelho Escuro, respectivamente. As adubacoes nitrogenadas formaram os tratamentos. Foram aplicados 4 niveis de sulfato de amonio (0, 90, 180 e 270 kg de N/ha), em duas parcelas: 1/3 no plantio e 2/3 20 dias apos o plantio, recebendo a denominacao de nitrogenio no plantio. Para cada um destes niveis, foi realizada outra adubacao, em cobertura, aos 40 dias apos o plantio, com 3 doses de sulfato de amonio (0, 100 e 200 kg de N/ha), recebendo a deniminacao de nitrogenio em cobertura. Aos 40 e 50 dias apos o plantio foram coletadas em Vicosa e Capinopolis folhas que foram utilizadas para a analise de nitrogenio, fosforo, potassio, calcio, magnesio e enxofre. Na colheita, foram determinadas as producoes de graos de cada parcela, a altura da planta e da insercao da primeira vagem ...
