| Description |
|
| Key Management Points |
|
| vine maturity |
120 days after planting |
| vine growth |
rapid during early season |
| diseases |
early blight, common scab |
| defects |
blackspot injury |
| herbicide |
tolerant to all |
| tubers |
short dormancy, oversizes |
| seed |
many, evenly distributed |
| planting (processing) |
8-12 inch spacing 4 inch deep |
| nitrogen |
all preplant or distributed to mid-bulking, optimal total usually 150 to 180 lb/acre |
| petiole-N |
16-21, 000 ppm, 70 days post-plant 10-13,000 ppm, 100 post-plant |
| irrigation |
more early watering for tuber shape
more later watering for blackspot |
| Yield potential |
Medium |
| desiccation |
difficult when green
need to lessen oversizing |
| storage |
excellent sugars, little sugar ends
apply sprout inhibitor for processing |
