Automatic measurement of rice tiller angle from unmanned aerial vehicle images

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Rice (Oryza sativa L.) tiller angle is an important trait that influences plant architecture, canopy light interception, and yield potential. In this study, we proposed a deep learning‐based pipeline for automated measurement of rice tiller angle and plant base width using unmanned aerial vehicle (UAV) imagery.

Bayesian optimized color filter: A fast method for segmentation of plant phenotypes from 3D point cloud images

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Multispectral three‐dimensional (3D) imaging offers substantial potential for plant phenotyping, yet manual segmentation of plant organs remains a bottleneck in breeding programs. We developed a color‐based filtering workflow for faba bean (Vicia faba L.) point clouds that optimizes lower and upper thresholds of spectral indices and broadband ...

High‐throughput assessment of plant stand establishment, seedling vigor, and light interception in peanut using UAV‐based RGB and multispectral imagery

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract In peanut (Arachis hypogaea L.), plant stand establishment, seedling vigor, and canopy growth are key determinants of crop performance; yet traditional ground‐based assessment methods can be destructive, labor‐intensive, and limited in throughput.

The impact of public drop‐off boxes and autonomous delivery robots in last‐mile delivery

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 6, Page 3825-3854, November 2026.
Abstract The growing concern over emissions from last‐mile logistics is motivating the development of innovative delivery models aimed at reducing environmental impact and traffic congestion. To this end, we propose a last‐mile delivery scheme based on both public drop‐off boxes and autonomous delivery robots.

Climate change impacts on global wheat (Triticum aestivum L.) production: A comprehensive meta‐analysis of stressors, risks, and adaptation strategies

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Climate change is exerting profound and multidimensional pressures on global wheat (Triticum aestivum L.) production. Rising temperatures, higher vapor pressure deficit, and more frequent heatwaves reduce yields through strong, phenology‐dependent effects, with flowering and grain filling identified as the most vulnerable stages. Compound heat–
