Potato crop nutrition

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.

Potato advice

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

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.

Foliar nutrition increases potato tuber bulking

Potato tuber bulking can be maximised by optimising crop nutrition to maintain tuber growth rates throughout the important bulking stage.

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.

Agronomy Advice - Increase potato yield with better phosphate management

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 increase potato yield

The two key yield components of potato are tuber numbers per unit area, and tuber size or weight. Increased yields come from achieving the optimum tuber numbers, maintaining a green leaf canopy, and increasing tuber size and weight.

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.
