Not all potato seeds are suitable for your farm’s agroecological zone. To plant the best for the highest yields and income, consider the following factors.
- Intended usage whether for making crisps, chips or mashing
- Altitude range in meters above sea level
- Maturity period in number of days it takes to mature from planting
- Potential yield per acre
- Tuber skin and flesh color
- Tuber dormancy
- potato seed’s tolerance, susceptibility and resistance to diseases like late blight.

You can grow potato varieties that are either best for making crisps, chips, or mashing.
Best potatoes for crisps have low starch, have a fresh look, and are firm. Select ones with a longer tuber dormancy since the best crisps are made of potatoes with shallow eyes and no sprouts.

potato farming challenges in in Kenya
Low yields While the potato yield per acre for most potato yields is 16-4o tons per acre, the national average of potato farming is 3.3 tons per acre. As a farmer observe good crop management, control pests, and diseases, and apply the right fertilizer amounts to double your yields to at least 8 tons per acre.
Post-harvest food waste: Most of the harvested potatoes goes to waste before consumption. It rots in the farms or sprouts before it can be sold. Though there are interventions to erect potato cold rooms in high potato-producing areas like Molo, Nyandarua, and Meru counties, as a farmer you can plant varieties with low sprouting, susceptible to fast rot, and use simple storage methods to increase its shelf life.
