Association of Agro‐Morphological Traits With Cup Quality in Accessions of Coffea arabica L. From the INIA Germplasm Bank, Peru

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT In recent years, Peruvian coffee production has increasingly focused on specialty coffees, with cup quality (CQ) as a key criterion. While previous studies have characterized the Coffee Germplasm Collection of the National Institute of Agrarian Innovation (CGC‐INIA), few studies have analyzed coffee cup quality.

Thermal sensitivity and yield of Arabica coffee under climatic variability

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Coffee yield is influenced by climatic factors, with temperature and water availability being key determinants. This study aimed to evaluate the effects of climate variability on the yield of Arabica coffee (Coffea arabica L.) cultivars across phenological phases and to validate an agrometeorological model at local and regional scales using ...

Nano‐Encapsulated Cinnamomum cassia Essential Oil in Combination With Fluconazole Exhibits Synergistic Activity Against Fluconazole‐Resistant Nakaseomyces glabratus and Pichia kudriavzevii

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Nano‐encapsulated Cinnamomum cassia essential oil (nano‐CC‐EO) showed in vitro antifungal activity against fluconazole‐resistant Nakaseomyces glabratus and Pichia kudriavzevii clinical isolates. Checkerboard assays revealed synergistic or additive interactions between nano‐CC‐EO and fluconazole in several isolates, without evidence of antagonism. These

First Occurrence of Coffee Leaf Rust Caused by Hemileia vastatrix on Coffee in Saudi Arabia

Microbiology Research
Coffee leaf rust (CLR) is a major disease of Arabica coffee caused by the biotrophic fungus Hemileia vastatrix. Jazan region in Saudi Arabia has long been one of the last coffee-producing regions in the world free of this disease. In August 2023, CLR was

Foundation Model‐Assisted Segmentation Enables Robust Field‐Based Severity Estimation: A Case‐Study of Coffee Leaf Rust

Plant Pathology, Volume 75, Issue 3, May–June 2026.
Foundation model‐assisted segmentation enables accurate field estimation of coffee leaf rust severity. Using 1285 images and curated lesion masks, we compared SAM3, SAM2, DeepLabV3+ and classical threshold methods. SAM3 achieved the highest segmentation accuracy and best agreement with reference severity, demonstrating reliable, scalable disease ...

Soil organic matter and F1 hybrid cultivar influence Coffea arabica yields in south‐central Guatemala

Agronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract Smallholders produce 60% of global coffee (Coffea arabica) supply but lack recommendations on nutrient management. We tested hypothesized N‐ and K‐driven yield gaps using on‐farm omission trials established across 21 fields in Guatemala. The effects of a single and combined application of N (285 kg ha−1) and K (350 kg ha−1) were evaluated for ...
