Effects of watering potato plants before harvest and of curing conditions on development of tuber diseases during storage
- 61 Downloads
Plots of potato plants were watered to field capacity one day before harvest on three dates, and tubers from watered and non-watered plots were stored at 7°C and 95% RH immediately or after curing at 15°C either at 80% or 95% RH. Watering increased the severity of silver scurf after storage when tubers were not cured. Curing at 80% RH decreased the disease and amounts were similar from watered and non-watered plants. Black dot was increased by watering whereas black scurf and golding blotch were decreased.
