Pre-sprouting of potato seed tubers (Liveseed Practice Abstract)
2020
Skrabule, Ilze
Practical Recommendations - 2 to 8 weeks before planting, place seed tubers in the light, avoiding direct sunlight. Longer exposure to light causes bigger tuber size of new yield, while shorter exposure promotes higher tuber number. - Split seed tubers in shallow boxes with higher corners, stack filled boxes, leave space between stacks OR pour seed potatoes in net-bags and hang them up. - Favourable temperatures are 12-15 °C during the day and 4-5 °C during the night. Make sure the tubers are protected against night frost. - Strong and short light sprouts will appear on tubers, they will be durable to mechanical damages. Potato planters can be safely used. - Lower night temperature tempers the sprouts.
