Location:

all types of soil; avoid soil which is susceptible to scab

Planting material preparation:

it is recommended to condition and prepare the seed

Chemical seed treatment:

recommended against rhizoctonia

Plant canape development:

uniform emergence with rapid foliage development

Nitrogen (N):

100-120 kg/ha incl. Nmin

split the N application, especially on light and irrigated locations

Phosphorus (P₂O₅):

80-100 kg/ha

Potassium (K₂O):

250-300 kg/ha

2/3 before planting (chloride), 1/3 after row closure as chloride-free potassium fertilizer

Magnesium (MgO):

80-100 kg/ha

Herbicides:

usage of herbicides containing metribuzin is possible before emergence

Fungicides:

apply fungicides according to local or regional risk models

Insecticides:

according to local warning service (if available)

At harvest considerations:

careful harvesting; avoid tuber temperatures <10°C; check skin set before harvesting, green harvesting possible

Storage:

long dormancy with good to very good storability
