“…These results are within the range of values reported by Azevedo et al (1993) (440 mm), Bezerra et al (2010) (543 mm), Farahani et al (2008) (878 mm), Howell et al (2004) (757 mm), and Zhou et al (2012) (538 mm). However, comparison of these values with other studies is difficult because the ET values are influenced by numerous local factors such as weather, soil characteristics, crop practices, water management, length of growth season, and strongly responds to the magnitude of incoming solar radiation (Alberto et al, 2011;Bezerra et al, 2012).…”

“…Ordinarily, latent heat flux or ET is the largest consumer of available solar energy especially in irrigated agriculture consuming 60-80% of net radiation in a growing season (Suyker & Verma, 2008). The ET process is controlled by several interacting biophysical and environmental factors including soil moisture, canopy conductance, leaf area, net radiation, temperature, vapor pressure deficit, and wind speed (Alberto et al, 2011).…”

“…Zain et al (2014) found that 15-day water stress cycle reduced rice transpiration rate by 42% and, as it has positive correlation with net photosynthesis rate, reduced grain yield. Rice evapotranspiration also decreases with water stress (Alberto et al, 2011) and is linearly related to grain yield (Cruz & O'Toole, 1982).…”

A B S T R A C TTo achieve an accurate phenotyping for drought tolerance, it is important to control water stress levels and timing. This study aimed to determine water use by upland rice plants during periods of irrigation withholding and its relationship with grain yield in order to increase the efficiency of this phenotyping. Two experiments were carried out in a randomized block design in which six water treatments (irrigation withholding for periods of 2, 4, 6, 8, 10 and 12 days) were compared, with four replicates. In the first experiment, treatments were applied at the R3 stage (panicle exsertion) and, in the second, at the R5 stage (beginning of grain filling). The amount of water evapotranspired was determined by the difference between the soil water storage at the beginning and at the end of irrigation withholding periods, from the surface to 80-cm depth. Evapotranspiration of upland rice from R3 stage was higher compared to that observed from R5 stage, when subjected to similar irrigation withholding periods in both growth stages. Rice grain yield is more sensitive to irrigation withholding imposed from R5 stage than from R3 stage.Evapotranspiração e produtividade do arroz de terras altas afetadas pela deficiência hídrica R E S U M O Para se obter fenotipagem acurada para tolerância à deficiência hídrica, é importante controlar o nível de estresse hídrico e a época de sua aplicação. Este trabalho objetivou determinar o uso de água pelas plantas de arroz de terras altas durante períodos de supressão da irrigação e sua relação com a produtividade de grãos, para aumentar a eficácia desta fenotipagem. Foram conduzidos dois experimentos no delineamento de blocos ao acaso e comparados seis tratamentos hídricos (supressão da irrigação por períodos de 2, 4, 6, 8, 10 e 12 dias) com quatro repetições. No primeiro experimento os tratamentos foram aplicados no estádio R3 (emissão das panículas) e no segundo, no estádio R5 (início do enchimento de grãos). A água evapotranspirada foi determinada pela diferença entre o armazenamento de água no solo no início e no fim dos períodos de supressão da irrigação, da superfície até 80 cm de profundidade. A evapotranspiração do arroz no estádio R3 foi mais alta comparada com a observada no estádio R5, quando submetida a período similar de supressão da irrigação em ambos os estádios. A produtividade do arroz foi mais sensível à supressão da irrigação imposta a partir do estádio R5 do que do estádio R3.
