Biophysical Constraints to Robusta Coffee Productivity in Low, Moderate, and High Rainfall Areas

International Journal of Agronomy, Volume 2024, Issue 1, 2024.
Globally, coffee (Coffea spp.) is a major commodity in terms of production and trade. Although Uganda is seventh among the major producing countries, yields remain low at 500 kg/ha. Understanding the biophysical constraining factors is vital to inform efforts toward closing the yield gap.

Reação de genótipos de cafeeiro à Hemileia vastatrix e à Cercospora coffeicola [PDF]

, 2020
Coffee plants were introduced in Brazil in the Northern State of Para around 1727. Two major diseases have affected coffee trees in the country. One is rust, caused by fungus Hemileia vastatrix and accountable for production losses up to 50%. The other one is Cercospora leaf spot, caused by fungus Cercospora coffeicola endemic to all Brazilian coffee ...

Climatic conditions in the cercosporiosis (Cercospora coffeicola) incidence and leaf-miner (Leucoptera coffeella) in coffee cultivars in Monte Carmelo, Minas Gerais, Brazil

, 2021
The genetic material adapted to the Cerrado Mineiro conditions and the monitoring can be a determining factor for the efficient management of coffee pests and diseases. In this context, the objective was to evaluate the climatic conditions in the cercosporiosis incidence and leaf-miner in coffee cultivars in Monte Carmelo, Minas Gerais.

Citronella essential oil in the control and activation of coffee plants defense response against rust and brown eye spot Óleo essencial de citronela no controle e na ativação de respostas de defesa do cafeeiro contra a ferrugem e cercosporiose

Ciência e Agrotecnologia, 2012
The rust and brown eye spot are the main coffee diseases. The losses are due to intense defoliation of plants, which has reduced its production and longevity. The brown eye spot also occurs in fruits, with negative effects on the beverage quality.
