Harvested potato
Potato farming in Kenya exhibits strong profit potential, with annual profits of KES 133,100 per acre under optimal management.
However, investors face significant risks, including potential losses of KES 59,000 to KES 197,000 per acre during market crashes, disease outbreaks, or marketing failures.
The investment requires KES 160,000-200,000 per acre but can generate attractive returns of 66-83% annually or devastating losses of up to 89% of the investment.
