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. A diagnostic study was conducted in 150 coffee fields to determine the most yield-limiting factors under varying rainfall thresholds, categorized as low ≤ 1100 mm/year, moderate ≥ 1100 to 1200 mm/year, and high ≥ 1200 mm/year. Robusta yield, soil parameters, pest and disease proportions, and tree and banana intercrop densities were measured under the thresholds. Parametric methods and the boundary line approach were used to analyze limiting factors and yield gaps. The results indicated that yields were significantly (p |
