| Storability: |
Russet Nugget stores well late into the shipping season with few problems and negligible sprouting. |
| Production Mgmt: |
Plants emerge quickly. Rangy root system aids in providing adequate water and nutrient uptake for the large vines. Hail damage is generally minimal. Tubers have medium dormancy. Fertility needs are very minimal compared to other major russet cultivars. Excess nitrogen early in the growing season may delay tuber inititation and bulking in favor of excess vine development. Excellent drought tolerance. No major herbicide sensitivities are known. Profuse flowering may result in large numbers of insects being present and psylled injury is common. Tubers are set near the middle of the hill and spread throughout by harvest. |
