Summary: | The objective of this work was to evaluate the adaptability of different lettuce (Lactuca sativa) cultivars grown in no-tillage on straw of ruzi grass (Urochloa ruziziensis), as well as its effects on soil temperature and weed control, in successive cultivations in the summer. The treatments were carried out in a randomized complete block design, with four replicates, in a split-plot arrangement (2x4), in which soil management (no-tillage on ruzi grass and convention tillage) was the main plot, and the different crisphead lettuce cultivars (Amanda, Solaris, Vanda, and Vera), the subplots. No difference was observed between cultivars for soil management. No-tillage reduced the soil temperature by up to 3.7°C and weed density by 3.7 times, in comparison with conventional tillage. Ruzi grass promoted a greater bed conservation. In comparison to with conventional tillage, the no-tillage management of lettuce cultivated on ruzi grass straw resulted in a lower yield in the first crop due to excess straw; in a similar yield in the second crop; and in a greater yield in the third crop. Lettuce cultivated on ruzi grass straw in no-tillage management results in a greater sustainability, in comparison with conventional tillage, in three successive plantings. |

Os tratamentos foram dispostos no delineamento experimental de blocos ao acaso, com quatro repetições, em arranjo de parcelas subdivididas (2x4), em que os manejos do solo (plantio direto sobre capim-congo e plantio convencional) constituíram a parcela principal, e as diferentes cultivares de alface tipo crespa (Amanda, Solaris, Vanda e Vera), as subparcelas. As cultivares não diferiram entre si quanto ao manejo do solo. O plantio direto reduziu a temperatura do solo em até 3,7ºC, e a densidade de plantas daninhas em 3,7 vezes, em comparação ao plantio convencional. O capim-congo promoveu a maior conservação dos canteiros. Em comparação ao plantio convencional, o plantio direto de alface sobre palhada de capim-congo resultou em produtividade menor no primeiro cultivo, em razão do excesso de palha; em produtividade semelhante, no segundo cultivo; e produtividade superior, no terceiro cultivo. O cultivo de alface em plantio direto sobre palhada de capim-congo resulta em maior sustentabilidade, em comparação ao plantio convencional, ao longo de três cultivos sucessivos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFundação de Amparo à Pesquisa do Estado de São Paulo (Fapesp)Hirata, Andréia Cristina SilvaHirata, Edson KiyoharuCamara, João Augusto Rizzo2018-10-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/25868Pesquisa Agropecuaria Brasileira; v.53, n.7, jul. 2018; 824-832Pesquisa Agropecuária Brasileira; v.53, n.7, jul. 2018; 824-8321678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/25868/14248https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/25868/17564Direitos autorais 2018 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2018-10-09T16:25:54Zoai:ojs.seer.sct.embrapa.br:article/25868Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2018-10-09T16:25:54Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
