Agricultural Systems

The three broad agroclimatic zones (humid, subhumid, and semi-arid) in Uganda are characterized by different agricultural systems. The humid agroclimatic zone is found mainly in the highlands (Mt. Elgon in the east and Mt. Muhavura in the southwest). Mt. Elgon is a banana-coffee (arabica) agricultural system, while Mt. Muhavura is under the Irish (Idaho) potato-sorghum (annual crops) agricultural system. The subhumid Lake Victoria crescent is characterized by the banana-coffee (robusta) system.

1 e i basin is a mixed farming system with a good integration of cultivation of annual crops (e.g., finger millet, Eleucine indica; sorghum; cassava, Manihot esculentum; cotton, Gossypium hirsutum), and cattle raising.
