KRONE

Krone is a robust variety with very good storability.
By planting this variety you can get high marketable
yields even under dry conditions.

VARIETY DESCRIPTION

QUALITY

Cooking type B, excellent taste, no discoloration after cooking, easily washable, very suitable for prepacking, very low sensitivity to mechanical damage, starch content 12 – 13 %.

YIELD

High number of tubers, very uniform grading, very high marketable yield.

RESISTANCES

  • PCN: Ro 1, 4
  • Y-Virus (PVY): high
  • potato leaf roll virus (PLRV): medium
  • late blight: medium
  • black leg: high
  • common scab: high

TUBER

Oval to long-oval, light yellow skin, smooth shallow eyes, yellow flesh colour.

PLANT

Medium tall, white flowers, foliage development medium.

PLANTING

Krone can be produced on all types of soil. Seed tubers should be warmed up before planting. Krone should be planted in rows allowing 30 – 32 cm between tubers and 75 cm between rows in a well-prepared seedbed 2 cm deeper than normal. Krone is fit for growing within short periods of time under dry conditions. Preventive chemical control of Rhizoctonia solani is recommended

FERTILIZATION

Krone has a high nitrogen efficiency, so N-fertilisation should be reduced (130 – 140 kg max. including N min.) Phosphorus: 100 kg / ha Potassium: 250 – 300 kg / ha (preferably sulphate) Magnesium: 80 kg / ha by low pH-value addition of micronutrients.

PLANT PROTECTION

Krone is not sensitive to Metribuzin. Routine protective control of late blight is recommended, addition of a fungicide to chemical haulm killing.

HARVEST

Krone must be senescing before haulm killing. Take care that skin set is finished before harvest.

STORAGE

Good dormancy, good suitable for a long term storage.
