Inoculation and Evaluation of Hemileia vastatrix Under Laboratory Conditions

, 2023
AbstractThe coffee leaf rust, a disease caused by the biotrophic fungusHemileia vastatrix, is one of the main limitations in coffee production today as it causes significant economic losses to the coffee production sector. Genetic improvement is an option to solve these problems.

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 ...
