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.
