Resumo: | Soil compaction is commonly observed in cultivated no-tillage soils, and may cause reductions in crop yields due to limited root growth. This study aimed to evaluate the influence of different levels of soil compaction on wheat yield grown in an Oxisol (Nitossolo Vermelho distroférrico - Brazilian Soil Classification System). The experiment was conducted at the Experimental Station of the Federal Technological University of Paraná (UTFPR), Campus Dois Vizinhos, PR, Brazil. The treatments consisted of: no-tillage (PD), tillage with additional compression (PDA) and tillage with mechanical scarification (PDE). We evaluated the density, porosity and resistance to penetration at every 0.05 m to 0.25 m in depth, as well as the productivity of wheat, grain weight and hectoliter weight. It was found that in the topsoil are the lowest soil densities (Ds), greater macroporosity and total porosity at the three situations, where in the layers below 0.05 m the treatments PD and PDA exceeded the critical value of 1.30 kg dm-3 for clayey soils. Additional compaction to the no-tillage system adversely affected the physical properties of the soil in the topsoil above 0.05m, where increases in the soil density, penetration resistance and reduced macroporosity and total porosity were observed. The mechanical scarification improved the physical properties of the soil to a depth of 0.1 m after thirteen months of intervention, outperforming the other systems. However, the use of a subsoiler to reduce soil compaction did not contribute to increased productivity and quality of wheat grain. |

O estudo objetivou avaliar a influência de níveis de compactação do solo, na produtividade de trigo cultivado em um Nitossolo Vermelho distroférrico úmbrico. O experimento foi realizado na Estação Experimental da Universidade Tecnológica Federal do Paraná (UTFPR), Campus Dois Vizinhos, PR, Brasil. Os tratamentos consistiram: sistema do plantio direto (PD), plantio direto com compactação adicional (PDA) e plantio direto com escarificação mecânica (PDE). Avaliou-se a densidade, a porosidade e a resistência do solo a penetração a cada 0,05 m até a profundidade de 0,25 m, bem como a produtividade do trigo, a massa de grãos e o peso hectolitro. Constatou-se que na camada superficial do solo ocorreram as menores densidades de solo (Ds), maior macroporosidade e porosidade total nas três situações, sendo que nas camadas inferiores a 0,05 m os tratamentos PD e PDA, superaram o valor crítico 1,30 kg dm-3 para solos muito argilosos. A compactação adicional ao sistema plantio direto afetou negativamente as propriedades físicas do solo, na sua camada superficial, acima de 0,05 m, sendo observados incrementos de densidade do solo, na resistência à penetração e redução da macroporosidade e porosidade total. A escarificação mecânica melhorou as propriedades físicas do solo até a profundidade de 0,1 m, após treze meses de intervenção, superando os demais sistemas avaliados. Entretanto, o uso do implemento subsolador, como forma de reduzir a compactação do solo, não contribuiu para o aumento da produtividade e a qualidade dos grãos de trigo.Universidade Federal de Viçosa - UFV2015-02-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/46710.13083/reveng.v23i1.516Engineering in Agriculture; Vol. 23 No. 1 (2015); 19-28Revista Engenharia na Agricultura - REVENG; v. 23 n. 1 (2015); 19-282175-68131414-398410.13083/reveng.v23i1reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/467/329Toigo, SoniaBraida, João AlfredoPossenti, Jean CarloBrandelero, Evandro MartinBaesso, Murilo Mesquitainfo:eu-repo/semantics/openAccess2023-01-19T13:22:29Zoai:ojs.periodicos.ufv.br:article/467Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:22:29Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false |
