How to influence potato tuber quality

How to influence potato tuber quality

There are three main criteria which define the quality of potato: tuber quality, skin finish and storage and cooking quality. A balanced crop nutrition program is important to help manage all of these criteria.

Whether you are looking to increase the quality and yield of a your potatoes or just need more general advice agronomy and crop nutrition information. See the latest advice from the Yara agronomists.

Potato nutritional summary
Potato nutritional summary
A correct balance between macronutrients and micronutrients is essential to obtain the best results possible from potato crops. A deficiency of any single nutrient is enough to limit crop yield.

How to increase potato tuber size
Tuber size and uniformity is critical for every market, whether it is fresh potatoes, seed or processing crops. Anything that the grower can do to prolong a healthy leaf canopy will increase the average tuber size.

Are your potatoes getting enough calcium?
Calcium is a vital nutrient for potatoes and most aspects of tuber quality can be improved by having a sufficient supply of calcium during growth.

Increase potato yields with better phosphate management
Ensuring sufficient phosphate is available for early development is critical in potatoes so perhaps it is time for a re-think about phosphate management.

How crop nutrition affects potatoes

How to improve potato skin finish
How to improve potato skin finish
Skin finish is important as consumers increasingly demand potatoes with clean, attractive skins. Tubers with surface infections of skin diseases are less attractive and also likely to have a reduced storage life.
How to reduce potato bruising
How to reduce potato bruising
Potato tuber bruising is a serious problem in the potato industry. Correct nutrition of the crop prior to harvest can minimise the risk of bruising occurring with potassium, calcium and boron all having effects that reduce bruising.
How to reduce incidence of potato foliar diseases
How to reduce incidence of potato foliar diseases
Nitrogen applications can have the effect of encouraging foliar diseases, particularly applications later in the season which delay maturity and increase the risk of blight infection.
