Cultivation practice
The onion belongs to the lily family.
The onion needs a minimum day length (photoperiod) for the formation of its bulb.
This threshold is different according to the varieties (from 12 to 16 H).
Temperatures above 18°C trigger bulb swelling, conversely, low temperatures initiate vegetative growth and the emission of floral stems (going to seed).
Weed and hoe regularly.
