Seed treatment:  Pre-sprouting is advisable.  This seedling should not be planted too early in the season and the soil should not be too cold.

Cultivation: This variety is moderately sensitive to the herbicide Sencor. This variety is slightly susceptible to common scab. The tuber resistance is quite good. Rudolph has a rather good resistance to mechanical damage and internal bruising (mechanical harvest is fine). Because of the rather long dormancy period, it can be stored for a long period.

Fertilisation: It will require less nitrogen than standard.  Since this variety is rather susceptible to black spot, the application of potassium should be a little higher than common.
