Resumo: | The objective of this experiment was to evaluate the effect of the water deficit on leaf rolling and expansion of corn cultivated in soils of different textures. The experiment was installed in an area of the Agricultural Engineering Department of the Federal University of Santa Maria. A set of 12 drainage lysimeters with dimensions of 1.56 m length, 1.00 m width and 0.80 m depth was used. A rain shelter was used to avoid precipitation on the experimental area. A completely randomized design, factorial (2x3), was used with two replications. Treatments consisted of two water management regimes (irrigated and terminal soil water deficit imposed during vegetative growth at 15 days after emergency (DAE) of maize plants of and three soil textural classes (clayey, loamy and sandy). Larger leaf rolling of corn plants submitted to water deficit was observed in clayey soil texture. A lesser reduction in leaf expansion was observed in corn plants cultivated in sandy soil and submitted to water deficit. |

O experimento foi instalado em área do Departamento de Engenharia Rural da Universidade Federal de Santa Maria. Utilizou-se um conjunto de 12 lisímetros de drenagem, com dimensões de 1,56 m de comprimento, 1,00 m de largura e 0,80 m de profundidade, protegidos das precipitações através de uma cobertura móvel de plástico transparente. Os tratamentos consistiram de dois níveis de manejo da água no solo (irrigado e aplicação de déficit hídrico durante a fase de crescimento vegetativo das plantas, aos 15 dias após a emergência (DAE) das plantas) e de três classes de textura de solo (argiloso, franco e arenoso). O delineamento experimental foi o inteiramente casualizado, fatorial, com duas repetições. Os resultados demonstraram que o maior enrolamento das folhas ocorre nas plantas de milho cultivadas em solo de textura argilosa e submetidas a déficit hídrico, enquanto a menor redução na expansão dessas folhas de milho foi observada em plantas cultivadas em solo de textura arenosa, submetidas a déficit hídricoUNESP, FCAUFSM, CCRUNESP, FCADepartamento de Engenharia Agrícola - UFCGUniversidade Estadual Paulista (Unesp)UFSMSantos, Reginaldo Ferreira [UNESP]Carlesso, Reimar2021-07-14T10:27:02Z2021-07-14T10:27:02Z1999info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article1-6application/pdfhttp://dx.doi.org/10.1590/1807-1929/agriambi.v3n1p01-06Revista Brasileira de Engenharia Agrícola e Ambiental.
