Infrared thermography as a tool for measuring water stress index in avocado cultivars ( Persea Americana M.)
Avocado cultivation is susceptible to water stress during the flowering stage and early fruit growth. This stress can cause premature fruit drop and exacerbate alternate bearing. Objective. To determine the crop water stress index (CWSI) in three avocado cultivars (Hass, Fuerte, and Zutano) under different irrigation conditions using infrared thermography. Materials and methods. The study was conducted in the fall of 2023 at the Canaán Agricultural Experiment Station, Ayacucho, Peru. One hundred
Production systems of Hass avocado among small-scale Colombian farmers: assessment and strategies for strengthening sustainable integration into export markets
Introduction: Colombia’s Hass avocado sector has grown rapidly, yet smallholders face unequal access to technology, certification, and export channels. Understanding the determinants of sustainable practice adoption is key to inclusive competitiveness and compliance with international standards.Methods: We analyzed a cross-sectional survey of n = 3,867 small-scale Hass avocado producers across 18 departments (2023–2024). Descriptive statistics and correlation analysis were followed by four
Avocado drought stress alleviation through different soil amendments
"
Under the uncertain scenario of water availability for irrigation, plants are often exposed to drought periods, which can negatively impact their vegetative growth and yield potential. To address this issue, various soil amendments including inorganic, organic, and biological treatments, have been investigated as solutions for mitigating water stress. However, comparative studies of different amendments are lacking. The aim of this study was to assess the efficacy of various soil amendments

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
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. Irrig Sci (submitted); Paredes et al.
IS-SAR: an irrigation scheduling web application for Hass avocado orchards based on Sentinel-1 images
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
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
