Single and basal crop coefficients for estimation of water use of tree and vine woody crops with consideration of fraction of ground cover, height, and training system for Mediterranean and warm temperate fruit and leaf crops

Authors: Pereira, L. S.,; Paredes, Paula; Oliveira, C. M.; Montoya, Francisco; López-Urrea, Ramón; Salman

This paper reviews the research on the FAO56 single and basal crop coefficients of fruit trees and vines performed over the past twenty-five years and focus on Mediterranean and warm temperate trees and vines. Two companion papers (López-Urrea et al., (2023) Single and basal crop coefficients for estimation of water use of tree and vine woody crops with consideration of fraction of ground cover, height, and training system for temperate climate fruit crops.

IS-SAR: an irrigation scheduling web application for Hass avocado orchards based on Sentinel-1 images

Authors: Erazo-Mesa, Edwin; Murillo-Sandoval, Paulo J.; Ramírez-Gil, Joaquín Guillermo; Benavides, Kevin Quiroga; Sánchez, Andrés Echeverri

As the Hass avocado crop expands exponentially in Colombia, concern about its increasing water use is on the rise. This research aimed to develop IS-SAR, a free-access web application to schedule irrigation for Valle del Cauca’s Hass growers. We calibrated the water cloud (WCM) and artificial neural network (ANN) models using field data measurements from Hass avocado orchard plots in Valle del Cauca (Colombia) and Sentinel 1 (S1) satellite imagery measurements and evaluated their performance

Water stress tolerance is coordinated with water use capacity and growth under water deficit across six fruit tree species

Authors: Opazo, Ismael; Pimentel, Paula; Salvatierra, Ariel; Ortiz, Mauricio; Toro, Guillermo; Garrido-Salinas, Marco

To compare water stress tolerance traits between different fruit tree species under the same experimental conditions can provide valuable information for understanding the mechanisms underlying water stress tolerance in a broader sense. This work aimed to determine and compare the water stress tolerance of six fruit tree species typically cultivated in Mediterranean regions, i.e., pomegranate, fig, mandarin, avocado, and two Prunus species ('R40' and 'R20') and evaluate its association with water use

Towards use of life cycle–based indicators to support continuous improvement in the environmental performance of avocado orchards in New Zealand

Authors: Majumdar, Shreyasi; McLaren, Sarah J.

PURPOSE: A life cycle assessment (LCA) study was undertaken for the orchard stage of the NZ avocado value chain, to guide the development of indicators for facilitating continuous improvement in its environmental profile. METHODS: The functional unit (FU) was 1 kg Hass avocados produced in NZ, up to the orchard gate. The baseline model assessed avocados produced in fully productive orchards, using input data collected from 49 orchards across 281 ha in the three main avocado growing regions of

The impact of tree phenology on the response of irrigated avocado: The hysteretic nature of the maximum trunk daily shrinkage

Authors: Assouline, S.; Hochberg, U.; Silber, A.

The goal of this study was to check the feasibility of the use of dendrometers to monitor water stress levels in avocado trees (Persea americana Mill, cv. Hass) during the period of 2015–2017. This water stress was generated naturally during events of high vapor pressure deficit (VPD) that normally take place during the Israeli spring (May) and late autumn (September). It was also generated artificially by considering two irrigation regimes, one providing the crop water needs estimated using lysimeter

Soil erosion, runoff and nutrient losses in an avocado (Persea americana Mill) hillside orchard under different groundcover management systems

Authors: Atucha, A.; Merwin, i.; Brown, M.; Gardiazabal, F.; Mena, F.; Adriazola, C.; Lehmann, J.

Assess the influence of different groundcover management systems on erosion and runoff processes associated with extremely steep hillside avocado (Persea americana Mill) orchards, in a Mediterranean climate with high rainfall variability. We compared several groundcover management systems at a steep hillside avocado planting in a three-year study: 1) Bare soil (BS), pre- and post-emergence herbicides; 2) Vegetation strip (VS), post-emergence herbicide applied in a 1-m wide strip on the tree row plus
