Suggested fertiliser treatment
Nitrogen: standard advice +10% to avoid very high dry matter levels.
Potassium: standard advice + 15% to reduce bruising and harvest damage.
Phosphate: standard advice.

Cultivation
Chitting is recommended but, de-sprouting can have a negative impact.
Carolus is susceptible to Common Scab, avoid the lighter soils and ensure that irrigation is timed for tuber initiation.

Plant spacing
35/55mm: 25cm (45,000 plants/Ha).
Spacing figures for 90cm row width.

Herbicide sensitivity
Do not use Metribuzin (Sencorex) as it gives a sever foliage reaction and yield reduction.

Storage
Good dormancy, suitable for medium term storage.
