General remarks

Spunta is a very conventional and well-known table potato, suitable for production in many climates. Long, slightly kidney-shaped tubers with a pale skin and light yellow flesh. Spunta will produce big tubers with a high yield. The dry matter content is about 19.7%.

Maturity

Medium early.

Seed treatment

Pre-sprouting is recommended. Spunta has strong sprouts, however it is rather susceptible to “little potato disorder” and therefore should not be planted too early into cold seedbed conditions.

Cultivation

Good foliage development with good ground cover and thick stems. A few white flowers. Berries are very rare. To prevent misshapen tubers, Spunta requires a good soil structure. Spunta has a good tolerance to both drought and heat stress.

Fertilisation

Requires an average N-fertilisation (about 250 kg N per ha, including soil reserves), which seems to be sufficient for all soil types. Spunta is rather susceptible to magnesium shortage; an Mg-application might be necessary. The use of organic manure gives positive results.

Harvest

Spunta is susceptible to mechanical damage and rather susceptible to Fusarium (dry rot). Good resistance to internal bruising. Tubers should be lifted with care.

Storage

Spunta stores reasonably well if tuber damage has been avoided.

Resistance to diseases

Susceptible to Potato Cyst Nematodes. Immune to wart disease, race 1. Rather susceptible to foliage blight and tuber blight. Rather susceptible to Fusarium.
