Resumo: The objective of this work was to evaluate the relationship between the draft power (FT) in the fertilizer furrow-opener and the volume of mobilized soil in the sowing line as affected by the amount of residues, tractor traffic and furrow-opening working depth, and its influence on soybean agronomic performance. Treatments consisted of six residue dosages (DR), two fertilizer furrow-opener working depths (PT) and two soil traffic conditions – with and without tractor traffic – carried out in a randomized block design, in a split-split-plot scheme. The treatments were applied with or without irrigation under no-tillage on a Rhodic Paleudult soil. The different PT and tractor traffic conditions influenced FT significantly. Regardless of the irrigation conditions, DR treatments did not affect soybean grain yield and shoot dry matter weight. In the absence of irrigation, soybean productivity increased by 180 kg ha-1 when PT was changed from 0,064 to 0,10 m, which indicates fertilizer furrow-opener at greater depths as a viable practice to decrease the effects of drought on crop.

Os tratamentos englobaram seis doses de resíduos culturais (DR), duas profundidades de trabalho das hastes sulcadoras (PT) e duas condições de tráfego – com e sem tráfego de rodados de trator –, em blocos ao acaso e parcelas subsubdivididas. Os tratamentos foram aplicados com e sem irrigação, em Argissolo Vermelho, sob plantio direto. As diferentes PT e condições de tráfego influenciaram significativamente a FT. Independentemente da condição de irrigação, as DR não influenciaram a produtividade de grãos e a massa seca da parte aérea da soja. Sem irrigação, a produtividade da soja aumentou em 180 kg ha-1 quando a PT passou de 0,064 para 0,10 m, o que demonstra que a aplicação do fertilizante a profundidades maiores é uma prática viável para diminuir os efeitos da seca sobre a cultura.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraConte, OsmarLevien, RenatoTrein, Carlos RicardoXavier, Antônio Alexandre PetersenDebiasi, Henrique2010-12-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/2073Pesquisa Agropecuaria Brasileira; v.44, n.10, out. 2009; 1254-1261Pesquisa Agropecuária Brasileira; v.44, n.10, out. 2009; 1254-12611678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/2073/5837https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/2073/1521info:eu-repo/semantics/openAccess2012-06-17T11:53:41Zoai:ojs.seer.sct.embrapa.br:article/2073Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:53:41Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
