Resumo: The objective of this work was to evaluate the soil physical properties and the yield of flooded rice under no‑tillage, in the west border of Rio Grande do Sul, Brazil, compared with the conventional tillage system. The experimental design was completely randomized, with three experiments (E) and ten replicates: E1, no‑tillage after leveling (E1PDR) and conventional tillage with two harrowings at 0.0–0.07 m layer after leveling (E1C), after seven years of fallow of rice tillage, with sowing of rye grass in winter and grazing; E2, no‑tillage (E2PD) and conventional tillage (E2C), after native field; E3, no‑tillage (E3PD), no‑tillage after leveling (E3PDR), and conventional tillage (E3C) after rice under conventional tillage, during one year under native field. The soil physical properties differed little between the no‑tillage system and conventional tillage. Continued Oryza sativa tillage with irrigated rice caused soil compaction in the 0.07–0.10 m layers. The rice yield did not differ between the no‑tillage system and conventional tillage, in the experiments 1 and 2. In experiment 3, with greater amount of remaining rice straw, the yield was greater in the conventional tillage system.

Utilizou-se o delineamento experimental inteiramente casualizado, com três experimentos e dez repetições: E1, sistema plantio direto após nivelamento do terreno (E1PDR) e sistema convencional com duas gradagens a 0,0–0,07 m após nivelamento do terreno (E1C), sete anos de pousio do cultivo de arroz, com semeadura de azevém no inverno e pastejo animal; E2, sistema plantio direto (E2PD) e sistema convencional (E2C), após campo nativo; E3, sistema plantio direto (E3PD), sistema plantio direto após nivelamento do terreno com remaplan (E3PDR) e sistema convencional (E3C), após arroz irrigado em sistema convencional, durante um ano sob campo nativo. As propriedades físicas do solo diferiram pouco entre os sistemas de plantio direto e o sistema convencional. O cultivo continu do com arroz irrigado causou compactação do solo na camada 0,07–0,10 m. A produtividade de arroz não diferiu nos sistemas plantio direto e convencional, nos experimentos 1 e 2. No experimento 3, com maior quantidade de restos culturais de arroz, a produtividade foi superior no sistema convencional.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPqMunareto, Janete DenardiBeutler, Amauri NelsonRamão, Cleiton JoséDias, Naimã PintoRamos, Priscila VogeleiPozzebon, Bruna CanabarroAlberto, Cleber MausHernandes, Gustavo Cantori2011-02-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/9094Pesquisa Agropecuaria Brasileira; v.45, n.12, dez. 2010; 1499-1506Pesquisa Agropecuária Brasileira; v.45, n.12, dez. 2010; 1499-15061678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/9094/6172https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/9094/4466info:eu-repo/semantics/openAccess2014-11-17T16:11:23Zoai:ojs.seer.sct.embrapa.br:article/9094Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-17T16:11:23Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
