How crop nutrition affects potatoes

How to influence potato tuber numbers
How to influence potato tuber numbers
The numbers of potato tubers produced by each potato plant is influenced by agronomy and varietal potential. The nutrients phosphate, potassium, and calcium all influence tuber number.

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 influence potato starch content and quality
How to influence potato starch content and quality
Potatoes are one of the most important sources of starch worldwide. Variety choice is very important and potatoes with greater than 13% starch content are required in countries such as Germany. The higher the starch content, the lower the waste.
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.
