“…Crop evapotranspiration-ET c is an important variable used for calculating and monitoring water use in different periods. It can be measured by various techniques, such as lysimetry (Peters et al 2017;Xu et al 2018;Silber et al 2019), eddy covariance (Ortega-Farias et al 2010;Prueger et al 2018), soil-water balance (Abdelkhalik et al 2019;Domínguez-Niño et al 2020) and Bowen Ratio-Energy Balance (Souza et al 2016;Chebbi et al 2018).…”

The acai palm (Euterpe oleracea Mart.) is a fruit from the Amazon that is originally found in flooded areas. Over recent years, its marketability has gained significant interest in Brazil and abroad because of its agronomic, nutritional and economic potential. However, there is a lack of technical-scientific information about crop water requirements for irrigation management during the reproductive phase of acai palm. Therefore, the aim of this research was to estimate the water requirements (crop evapotranspiration (ET c ), single (Kc) and dual (Kcb + Ke) crop coefficients) of acai palm in the Eastern Amazon (Brazil) using the Bowen ratio system. A micrometeorological tower was installed in the center of an experimental area to monitor ET c and meteorological variables. Phenological development was monitored during two growing seasons. Soil water evaporation was determined on a daily scale using weighing microlysimeters. Ke and Kcb values were calculated by the ratio of soil surface evaporation and transpiration to reference evapotranspiration (ET o ), respectively. Total water requirements of the acai palms were 1165 mm, with a daily average of 3.49 mm day −1 for the growing season. The average values of Kc, Ke and Kcb for the acai palm were 1.08; 0.21 and 0.84, respectively. The findings will assist the design of irrigation management protocols for acai trees that are better tailored to satisfy crop water requirements. This will allow improved water use efficiency, ensuring tree crop sustainability.

“…The most common plant-based variables tested as potential triggering-irrigation parameters in Hass avocado crop are the maximum daily trunk-diameter variation (MTDV), trunk diameter growth rate (TGR), trunk diameter shrinkage (TDS), stem and leaf water potential (SWP and LWP), leaf stomatal conductance (gs), fruit diameter variation, leaf voltage differences, and photosynthesis rate (Turner et al, 2001;Winer and Zachs, 2007;Gil et al, 2011;Silber et al, 2013Silber et al, , 2019. A detailed list of water stress indicators in tree orchards is provided (Fernández, 2017).…”

“…From the DA approach, technologies that suit the Hass avocado IS (Ćulibrk et al, 2014) can be classified into three categories: proximal sensing (PS), remote sensing (RS), and mobile or web applications. Studies have reported the benefits of using IS in avocado orchards (Holzapfel et al, 2017;Moreno-Ortega et al, 2019;Silber et al, 2019), highlighting a reduction in crop water consumption and yield, and fruit quality improvement.…”

Under tropical conditions, Hass avocado irrigation is a controversial issue due to insufficient scientific evidence. The rapid progression of technological advances and its incorporation in agriculture have expanded options to improve the irrigation scheduling (IS) of Hass avocado. The concept featuring those technological advances in agriculture is digital agriculture (DA). Here, we present a mixture of well-known studies in the Hass avocado irrigation focused on proximal sensing (PS) technologies and recent studies emphasizing the potential of remote sensing (RS), and application technologies to schedule the irrigation. PS takes advantage of the soil or trees' proximity to output reliable measurements with a high temporal resolution, while RS provides a broad set of spectral data in continuous and large areas that can be transformed into crop-related biophysical variables. Applications – a term grouping mobile (smartphone) apps, desktop programs, and web-based platforms – offers portability, high precision, and graphic visualization of variables obtained or estimated by sensors. Integrating RS and PS technologies through user-friendly applications can represent a suitable option to improve Hass avocado irrigation in developing countries. Our review is presented in the following sections: general introduction, DA approach definition, use of proximal sensing, use of remote sensing, and scheduling irrigation applications.

“…Increasing the WW component in mixed irrigation water reduces trunk growth, which is minimal for irrigation with WW. Trunk growth was shown to be strongly related to tree transpiration and yield (Silber et al, 2019(Silber et al, , 2013. The reduction in simulated actual transpiration due to changes in soil hydraulic properties induced by irrigation with WW indicates that such irrigation contributes to a decrease in tree performances and, consequently, to the drop in yield.…”

The use of treated wastewater (WW) for irrigation is steadily increasing worldwide. However, irrigation with WW requires special attention as it may alter soil hydraulic properties and, eventually, affect crop yields. The main goal of this study was to investigate two approaches that could mitigate this adverse impact: (i) mixing WW with local freshwater (FW) and (ii) adjusting the irrigation management and design to the deteriorated soil hydraulic properties. Four water qualities resulting from mixing FW and WW at different ratios for irrigation of an avocado orchard planted on a clayey soil were considered: FW, M 1/3 (2/3 FW-1/3 WW), M 2/3 (1/3 FW-2/3 WW), and WW. Increasing the WW component in the irrigation water reduces the soil's saturated hydraulic conductivity and infiltrability, and this reduction is depth dependent. It also reduces the transpiration of trees and their trunk growth. This is supported by numerical simulations that showed that irrigation with WW produced the reduction in plant transpiration relative to irrigation with FW. Numerical simulations indicated that irrigation management and design could be adjusted to improve plant water uptake and reduce the differences due to water quality. The results indicate that decreasing the irrigation rate and increasing the wetted area per tree could increase the water uptake in WW-irrigated soils to almost equal that in FW-irrigated soils. This can be achieved by using drippers with lower discharge and by using more drippers per dripline, more driplines per tree, and more drippers per tree (concentric loops of driplines around each trunk).
