“…K c values concurred with those measured by other researchers (Alves et al, 2007;Yang et al, 2003). For example, Alves et al (2007) reported monthly K c average for citrus trees ranged from 0.9 to 1.11.…”

“…However, ET o during our study did not vary significantly (P = 0.45) between the greenhouse and the field station (FAWN). An early greenhouse study reported that measured ET o varied significantly from 0.6 mmÁd -1 in a cold weather to 7.0 mmÁd -1 in a warm weather (Yang et al, 2003). In this study, measured ET o ranged from 2.3 in Jan. 2014 to 4.8 mmÁd -1 in Aug. 2014.…”

“…Average air temperature inside the greenhouse was always higher than outside by 2.9°C. Yang et al (2003) reported similar observation where air temperature in the greenhouse was greater than outside by an average of 3.5°C. In agreement with our observations, they also found that the RH fluctuated inside and outside the greenhouse.…”

Understanding the role of Huanglongbing (HLB) caused by Candidatus Liberibacter asiaticus on citrus (Citrus sp.) water use is critical for determining if changes in water management of commercial citrus orchards affected by this disease is necessary. Reference evapotranspiration (ETo) is the most used methodology for irrigation scheduling, particularly in light of reports that indicate the lack of water for irrigation will become a major problem in many places around the world including Florida. The objectives of this study were to determine citrus tree water relationship [water use, sap flow, and stem water potential (Ψ)] as affected by ETo and HLB. The study was initiated on Jan. 2014 on two sweet orange (Citrus sinensis) cultivars included Hamlin and Valencia grown in a fine sandy soil texture (sandy, siliceous, and hyberthermic Arenic Alaquods) in a greenhouse. Twelve weighing lysimeters of each cultivar (six HLB-affected and six nonaffected trees) were used to determine selected water relation parameters. Results indicated a significant reduction in water use, Ψ, and sap flow for affected trees when compared with nonaffected trees. Citrus water use of healthy trees during the 2-year study was 31% and 27% greater than HLB-affected trees for ‘Hamlin’ and ‘Valencia’, respectively. Lower water use of HLB-affected trees resulted in 10% and 15% greater available soil water content than healthy ‘Hamlin’ and ‘Valencia’ trees, respectively. Therefore, reducing the water supply for HLB-affected trees than healthy trees may be a desirable practice that would lead to significant water savings.

“…This ensured automated and controlled irrigation of the lysimeters. Disturbed soil lysimeters for experimental purposes are allowed as long as the horizon distributions represent those of the original soil (Francaviglia et al, 2000;McFarland et al, 1983;Yang et al, 2003).…”

Weighing lysimeters differ in shape and size and are well established in measuring soil water balance components, such as evaporation, transpiration and drainage. This study addresses the development, calibration and testing of low‐cost small lysimeters for measuring evaporation and transpiration of barley in a glasshouse for three consecutive winter seasons (2011–2013). Forty‐one small lysimeters were developed and used during the study. The lysimeters were made from plastic materials mounted on Tedea‐Huntleigh model 1260 load cells. The temperature effect on the final mass reading from the load cells was corrected by deducing temperature correction factors for all the lysimeters. During calibration, the lysimeters had high linearity and no hysteresis. Sensitivities of the lysimeters ranged between 0.1 and 0.35 mm. The small lysimeters developed, installed and calibrated were able to measure evaporation and transpiration separately at high accuracy, sensitivity and precision. These lysimeters measured on hourly and daily bases, and were able to measure all the soil water balance components. Apart from the simplicity of these lysimeters, the water content of the whole soil profile could be easily monitored due to the deeper depth of the lysimeter. These small lysimeters were cheap to construct, and installation was easy compared to other lysimeters. Copyright © 2016 John Wiley & Sons, Ltd.

“…No entanto, diversos autores reportam o uso de lisímetros de pesagem como ferramenta padrão em estudos de perda de água das culturas, seja na determinação da evapotranspiração, como também na calibração de modelos agrometeorológicos de estimativa (Campeche, 2002;Silva Et Al., 1999;Howell et al, 1991) A grande maioria das informações quanto ao consumo hídrico das plantas cítricas, via lisimetria, provêem da literatura internacional (Green ;Bruwer, 1979;Boman,1994;Ginestar ;Castel, 1994;Castel, 1997;González-Altozano Et Al. 1999, 2000Yang et al 2003).…”

VARIAÇÃO SAZONAL NA EVAPOTRANSPIRAÇÃO DE PLANTAS JOVENS DE LIMA ÁCIDA ‘TAHITI’ Cláudio Ricardo da Silva1; José Alves Júnior1; Tonny José Araújo da Silva1; Marcos Vinícius Folegatti1; Luis Fernando de Souza Magno Campeche21Departamento de Engenharia Rural, Escola Superior de Agricultura Luiz de Queiróz, Universidade de São Paulo, Piracicaba-SP, csilva@esalq.usp.br2Departamento de Engenharia Agronômica, Universidade Federal de Sergipe 1 RESUMO O objetivo deste trabalho foi estudar a variação sazonal diária e horária na evapotranspiração de plantas jovens de lima ácida ‘Tahiti’ sob condições de campo. O estudo foi conduzido em Piracicaba, durante o inverno de 2003 e verão de 2004. Utilizou-se um lisímetro de pesagem eletrônica de 2,7 mde diâmetro e 0,8 mde profundidade com uma planta de dois anos de idade, localizado no centro da área experimental com 322 plantas. Todas as plantas do pomar foram irrigadas por quatro gotejadores autocompensantes, inclusive a do lisímetro. Os resultados permitiram verificar que no período de verão a média da evapotranspiração da cultura (ETc) foi de 1,50 mm dia-1 decrescendo a 0,66 mm dia-1 nos meses de inverno. O coeficiente de cultivo (Kc) médio obtido foi de 0,36 e 0,22 durante o período de verão e inverno, respectivamente. A ETc máxima para o período de inverno ocorreu às 14:00 h enquanto que no verão foi às 12:00 h. Além disso, ocorreram perdas por evaporação diária noturna de 17,4 % e 13,4% da ETc para o período de inverno e verão respectivamente. A curva de evaporação do solo (Ke) foi semelhante em ambos os períodos estudados. UNITERMOS: citros, lisímetro, coeficiente de cultivo, demanda hídrica SILVA, C. R. da; ALVES JÚNIOR, J.; SILVA, T. J. A. da; FOLEGATTI, M. V.; CAMPECHE, L. F. de S. M.; SEASONAL VARIATION IN EVAPOTRANSPIRATION OF YOUNG ‘TAHITI’ACID LIME TREES 2 ABSTRACT The objective of this study was to investigate seasonal variations in hourly and daily evapotranspiration (ETc) of acid lime ‘Tahiti’ trees under field conditions, defining values of crop coefficients. The study was carried out in Piracicaba, Brazil, during the winter of 2003 and the summer of 2004. Aweighing lysimeter of 2.7 mdiameter and 0.8 mdepth was planted with a two-year-old tree that was located at the center of an experimental area with 322 trees. The lysimeter tree was irrigated, like others in the plot, by four pressure compensated emitters. The average ETc was 1.50 mmday-1 in the summer and dropped to 0.66 mm day-1 in winter months. The average seasonal crop coefficient (Kc) was 0.36 and 0.22 for summer and winter, respectively. The maximum Etc time was at noon in the summer and at 2 pm in the winter. Moreover, night soil evaporation represented 17.4% and 13.4% of daily ETc in winter and summer. The soil evaporation curve (Ke) in both seasons showed similar results.
