“…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. Boman (1994) reported that the K c values for 5-year-old orange trees grown in lysimeters increased from 0.6 during December-February to 1.1 during June-July.…”

“…Previous studies reported similar citrus water use averages under different environmental conditions. For example, estimated ET c values for citrus ranged from 1.3 to 5 mmÁd -1 in Sao Paulo, Brazil (Alves et al, 2007), from 1.7 to 5 mmÁd -1 in flatwoods citrus (Rogers et al, 1983), or from 1.8 to 4.4 mmÁd -1 for ridge citrus, soils with unconfined coarse sand (Boman, 1994;Jia et al, 2007;Romero et al, 2009). Furthermore, Morgan et al (2006) represented citrus ET c values ranged between 1.1 and 6.5 mmÁd -1 in Florida sandy soils.…”

“…Various studies indicated that citrus water use averaged between 1.1 and 6.5 mmÁd -1 (Morgan et al, 2006;Rogers et al, 1983). Thus, estimates of water use coefficient (K c ) for citrus show a wide range of variations from 0.4 to 1.2 (Alves et al, 2007;Jia et al, 2007;Morgan et al, 2006). Decreasing available soil water content resulted in lower plant soil water uptake and thus lower K c values (Morgan et al, 2006).…”

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.

“…Concerning the citrus the obtained ETc was 1367 mm year -1 . The estimated value compares well with different studies ranging from 1257 mm year -1 in Sao Paulo, Brazil (Alves, et al 2006) to 1390 mm year -1 in California, USA (Snyder et O'Connell 2007). The green peas crop water requirement was also correctly estimated with an ETc of 412 mm year -1 when (Saha 2011) found 489 mm year -1 in Neh Region, India.…”

In the agriculture sector, combining physically based soil water balance and simulation models with GIS tools is of a considerable interest to manage the available water amount. Indeed, this combination can enhance water supply management, optimize agricultural catchments management and study impact of management intervention from small scale (plot) to a larger one, such as irrigated district and/or region.This work presents the case of Nebhana Dam System in the region of Kairoun (central Tunisia). The main objectives were to: (1) create a specific GIS database for the six irrigated districts of the area Ain Boumorra 1, 2 & 3, Fadhloun, Dar Jameya and Sisseb 1 based on the characteristics of cultivated crops, soils types and used irrigation systems;(2) assess spatial and temporal variation of soil water budget terms from plot and farm levels to irrigated district and regional scales; (3) map results for different time steps.The achievement of these objectives was made possible using the WEAP-MABIA Model. Thus, daily Penman-Monteith reference evapotranspiration (ETo), effective precipitation (PE), crop water requirement (CWR) and irrigation water requirement (IWR) were estimated for the six irrigated districts and their related farms and plot using spatially distributed parameters on climate, crop, soil characteristics, irrigation system and basic irrigation management practice during the cropping season 2014/2015.

The irrigated perimeter of Jaíba‐MG is located in a semi‐arid region of Brazil, which makes irrigation practices necessary in order to guarantee agricultural production. This need occurs in the context of limited water resources and, therefore, it is necessary to study ways to optimize water use efficiency (WUE). For this, it is necessary to obtain local and precise estimates of the crop coefficient (Kc) and the reference evapotranspiration (ET0). The objective of this study was to evaluate the water requirements and WUE of banana, lemon and mango crops in the irrigated perimeter region of Jaíba using satellite images and meteorological data. Landsat 8 satellite images from 2020 and 2021 were used to estimate the local Kc of these crops. Three methodologies for estimating local Kc were adopted: METRIC, NDVI and NDVI 2. The Kc NDVI method stood out when compared with the standard method (FAO Bulletin 56), with RMSEs of 0.11, 0.16 and 0.20 for banana, lemon and mango, respectively, showing the potential of this methodology. The overall average WUE values for banana, lemon and mango crops were 2.19, 1.58 and 1.58 kg m−3, respectively. The results could allow important advances in water management for fruit crops under semi‐arid conditions.
