Resumo: Correction of soils is a required practice that aims to reduce the harmful effects of soil acidity, promote better development of the plants and ensure the productive potential of agriculture. In this sense, the objective of this work was to evaluate the maize yield in monoculture and / or intercropped and to study the development of Urochloa spp roots according to different combinations of chemical correction of the soil in rainfed conditions. The experiment was developed in an experimental area, Selvíria, MS, Brazil in dystrophic Oxisol. The experimental design used was the randomized blocks with subplots, with three replications.  The soil correction treatments were arranged in the plots (control, gypsum, lime (0 - 0.2 m); lime and gypsum (0 - 0.2 m); lime (0 - 0.4 m); lime and gypsum (0 - 0.4 m)), and the subplots were occupied with maize, maize intercropped with U. ruziziensis or with Mulato II hybrid (Convert HD 364) The two intercrop with forages produced sufficient amounts of straw to start and/or maintain no-tillage system in the Cerrado region and the presence of forage in maize crop did not influence grain yield. The Mulato II hybrid had a larger root diameter, being more indicated for compacted soils, however longest root lengths were obtained by U. ruziziensis.

En este sentido, el objetivo de este trabajo fue evaluar el rendimiento del maíz en monocultivo y/o intercalado y estudiar el desarrollo de las raíces de Urochloa spp. según diferentes combinaciones de corrección química del suelo en condiciones de secano. El experimento se desarrolló en un área experimental, Selvíria, MS, Brasil en Ferrasol. El diseño del experimento se hizo en bloques aleatorios con parcelas subdivididas y tres repeticiones. Los tratamientos de corrección del suelo se dispusieron en las parcelas (control, yeso, cal (0 - 0,2 m); cal y yeso (0 - 0,2 m); cal (0 - 0,4 m); cal y yeso (0 - 0,4 m)), y las subparcelas se ocuparon con maíz, maíz intercalado con U. ruziziensis o con el híbrido Mulato II (Convert HD 364). Los dos cultivos intercalados con forrajes producían cantidades suficientes de paja para iniciar y/o mantener el sistema de siembra directa en la región de la sabana y la presencia de forraje en el cultivo de maíz no influyó en el rendimiento del grano. El híbrido Mulato II tenía un diámetro de raíz más grande, siendo más indicado para suelos compactados, sin embargo las longitudes de raíz más largas fueron obtenidas por U. ruziziensis.A correção dos solos é uma prática obrigatória que visa diminuir os efeitos nocivos da acidez, promover melhor desenvolvimento das plantas garantindo o potencial produtivo agrícola. Neste sentido, o trabalho teve como objetivo avaliar a produtividade do milho em monocultivo e/ou consorciado e estudar o comportamento das raízes de Urochloa spp em função de diferentes combinações de correção química do solo sob condição de sequeiro. O experimento foi conduzido no município de Selvíria, MS, Brasil em LATOSSOLO VERMELHO distrófico. O delineamento do experimento foi em blocos casualizados com parcelas subdivididas e três repetições. Os tratamentos de correção foram dispostos nas parcelas (controle, gesso, calcário (0 - 0,2 m); calcário e gesso (0 - 0,2 m); calcário (0 - 0,4 m); calcário e gesso (0 - 0,4 m)), e as subparcelas foram ocupadas milho solteiro, milho consorciado com U. ruziziensis ou consorciado com híbrido Mulato II (Convert HD 364). Os consórcios produziram quantidades suficientes de palha para iniciar e/ou manter o sistema de plantio direto na região do Cerrado e a presença das forrageiras na cultura do milho não influenciou o rendimento de grãos. O híbrido Mulato II possui maior diâmetro radicular, sendo mais indicado para solos compactados, embora a U. ruziziensis tenha obtido os maiores comprimentos radiculares.Research, Society and Development2020-06-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/477810.33448/rsd-v9i7.4778Research, Society and Development; Vol. 9 No. 7; e798974778Research, Society and Development; Vol. 9 Núm. 7; e798974778Research, Society and Development; v. 9 n. 7; e7989747782525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/4778/4219Copyright (c) 2020 Izabela Rodrigues Sanchesinfo:eu-repo/semantics/openAccessSanches, Izabela RodriguesLazarini, EdsonPechoto, Eduardo Augusto PontesSantos, Fabiana Lopes dosBossolani, João WilliamParra, Lucas FenelonMeneghette, Hugo Henrique Andrade2020-08-20T18:05:03Zoai:ojs.pkp.sfu.ca:article/4778Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:28:30.565257Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
