Resumo: | The objective of this work was to evaluate the relative agronomic effectiveness of the application of broadcasted and banded phosphorus rates, testing a standard source (triple superphosphate) and Arad phosphate rock in a soybean crop, in the Balsas, MA, Brazil. The experiment was carried out in October 2004, on a Typic Hapludox, clayey texture and very low available phosphorus, conducted with soybean [Glycine max (L.) Merrill.], cultivar BRS Sambaíba], for three consecutive harvests (2004/2005 to 2006/2007). The third harvest was carried out on residual effect of the previous applications. In general, it was not observed any differences related to the localization of the standard source. In contrast, Arad phosphate rock localization reduced the relative agronomic effectiveness significantly. In the first two harvests, broadcasted Arad phosphate rock resulted in approximately 76% of relative agronomic effectiveness, showing medium agronomic viability. Under residual effect, banded triple superphosphate resulted in similar response to that obtained with annual application of triple superphosphate, however, the increase in relative agronomic effectiveness was greater when broadcasting both phosphorus sources. |

Merrill.]. O superfosfato triplo foi a fonte-padrão, e o fosfato natural reativo Arad foi a fonte testada, ambos aplicados em diferentes doses, em área total ou no sulco de semeadura. Em outubro de 2004, o experimento foi instalado em Balsas, MA, em Latossolo Vermelho-Amarelo distrófico, textura argilosa e baixa disponibilidade de fósforo, conduzido com soja cultivar BRS Sambaíba por três safras (2004/2005 a 2006/2007); a terceira safra foi conduzida sob efeito residual das aplicações anteriores. De forma geral, não foram observadas diferenças quanto à localização da fonte-padrão, ao passo que a localização do fosfato natural reativo Arad reduziu significativamente a eficiência. Quando aplicado a lanço, nos dois primeiros cultivos, o fosfato natural reativo Arad resultou em aproximadamente 76% de eficiência agronômica relativa, o que demonstra média viabilidade agronômica. Sob efeito residual, a aplicação localizada do superfosfato triplo resultou em resposta semelhante à verificada com a aplicação anual desta fonte, entretanto, o aumento na eficiência agronômica relativa foi mais acentuado, quando ambas as fontes foram aplicadas a lanço.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraJunior, Adilson de OliveiraProchnow, Luís IgnácioKlepker, Dirceu2008-08-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/177Pesquisa Agropecuaria Brasileira; v.43, n.5, maio 2008; 623-631Pesquisa Agropecuária Brasileira; v.43, n.5, maio 2008; 623-6311678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/177/5430https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/177/171info:eu-repo/semantics/openAccess2014-06-09T17:22:36Zoai:ojs.seer.sct.embrapa.br:article/177Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-06-09T17:22:36Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
