|
Maturity
|
|
|
|
Red Scarlett is an early maturing variety with an early tuberisation.
|
Seed treatment
|
|
|
|
Sprouting proceeds normally. Pre-sprouting is not useful; Red Scarlett can be planted with small white buds.
|
Fertilisation

|
|
|
Nitrogen requirement is equal to other early varieties (about 10% higher than Desiree). Also a good Potassium fertilisation is recommended.
|
Cultivation
|
|
|
|
Red Scarlett performs best on clay soils. Because of the high number of tubers per plant, Red Scarlett can be planted a little wider than average.
The following can be advised:
seed size (mm.) plants per hectare
35 - 50 38.000 / 42.000
35 - 55 38.000 / 40.000
This variety is slightly susceptible to Sencor. Red Scarlett has a quick emergence and a rapid ground cover. This variety is high yielding with a regular grading.
Early and regular treatment against late blight (Phytophthora infestans) is advised.
|
Harvest
|
|
|
|
After haulm killing the skin must be set before harvest. The resistance to bruising and mechanical damage is good. If the crop is mature and lifted with care, harvest does not cause problems.
|
Storage
|
|
|
|
Moderate dormancy period. Red Scarlett can be stored well at a constant, rather low temperature.
|
Resistance to diseases
|
|
|
|
Red Scarlett is resistant to potato cyst nematode (Ro1) and to wart disease race 1. Moderately susceptible to late blight (Phytophthora infestans) in the foliage and slightly susceptible in the tubers. Good resistance to PVY, PVYntn and PLRV.
The common scab resistance is reasonable.
