Resumo: Soil moisture determination is essential for a good use of available water resources. In this regard, the use of frequency domain reflectometry (FDR) probes has as advantages mobility and practicality in relation to lysimeters. The experiment was carried out between April and June 2016 at the Luiz de Queiroz College of Agriculture (ESALQ/USP), located in Piracicaba, SP at the geographical coordinates 22°42?14.6? S and 47°37?24.1? W and altitude of 546 m. This study aimed to assess these FDR probes to estimate water consumption in comparison to measurements by weighing lysimeters (ETcLys) and reference evapotranspiration (ETo) in Mombaça and Bermuda grass pastures under single cultivation and overseeded with oat and ryegrass. Soil moisture was assessed daily by FDR probes by estimating crop evapotranspiration (ETcFDR probe) from soil water balance calculation, which was correlated with ETcLys and ETo (Penman-Monteith, FAO 56). For all treatments, FDR probes presented the highest water consumptions when compared to the other two evapotranspiration methods, with accumulations of 126.5 and 125.6 mm for single and overseeded Mombaça grass, respectively. For Bermuda grass, water consumption was 123.4 mm in the single cultivation and 128.5 mm when overseeded. The method of estimating evapotranspiration by FDR probes showed good correlations with ETo and ETcLys.

Neste aspecto, as sondas de Reflectometria no Domínio da Frequência (FDR) tem a vantagem da mobilidade e praticidade em relação aos lisímetros. O experimento foi conduzido entre abril e junho de 2016 na Escola Superior de Agricultura “Luiz de Queiroz” (ESALQ/USP), localizada em Piracicaba, SP nas coordenadas geográficas 22°42?14.6? S e 47°37?24.1? O e altitude de 546 m. O objetivo desse trabalho foi avaliar o uso de sonda FDR para estimativa do consumo de água em relação a medidas obtidas através de lisímetros de pesagem (ETcLis) e da evapotranspiração de referência (ETo) em pastagens de capim Mombaça e Cynodon em cultivos exclusivos e sobressemeados com aveia e azevém. A umidade de solo foi diariamente avaliada pela sonda FDR estimando a evapotranspiração de cultura (ETcsonda FDR), a partir do cálculo de balanço hídrico no solo, que foi correlacionada com a ETcLis e a ETo (Penman-Monteith - FAO 56). A sonda FDR apresentou para todos os tratamentos os maiores consumos em relação aos outros dois métodos de evapotranspiração, com acúmulos durante o ciclo de 126,5 mm e 125,6 mm, no Mombaça exclusivo e sobressemeado, respectivamente. No Cynodon spp., o consumo foi de 123,4 mm no cultivo exclusivo e 128,5 mm no sobressemeado. O método de estimativa de evapotranspiração pela sonda FDR apresentou boas correlações com a ETo e ETcLis.UEL2019-05-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionfield experimentapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3344510.5433/1679-0359.2019v40n3p1115Semina: Ciências Agrárias; Vol. 40 No. 3 (2019); 1115-1126Semina: Ciências Agrárias; v. 40 n. 3 (2019); 1115-11261679-03591676-546Xreponame:Semina.
