For potatoes to be deemed to be of good quality, the tubers must have certain characteristics and attributes. Factors that lead to a good quality tuber include: seed quality, good agricultural practices, environmental and climatic factors, handling, and storage. The use of certified seeds alongside following through with Gap’s guarantees quality potatoes since  certified seed potato have been tested for diseases that damage potatoes, reducing their quality.

The other determinant is where and how the potato is grown. Soil type and quality, altitude, rainfall, and temperature affect the growing environment. Inputs such as fertilizer, manure, and agrochemicals affect the plant’s health and the output from the crop. Harvesting method is also critical in determining the quality of potatoes. Bruised potatoes have a low shelf life and are not preferred by consumers neither are they good for processing.

After harvesting, potatoes are sorted for packaging. Storage condition is critical in maintaining good-quality potatoes. Dark cold storage prevents the potatoes from sprouting and changing color and helps maintain freshness.

Finally, transport method can also affect quality. Transporting using recommended bags or packages reduce the chances of bruising and damage from sunlight.
