Superex Onion (Superex F1): Characteristics
Superex onion is an F1 hybrid onion variety, also sold or known as Superex F1 or submarine sibuyas. It is not a registered variety, so the facts here come from its seller and farm sources. It comes from Ramgo.
The average and top yields in tonnes per hectare come from the trials each variety went through to be registered with the NSIC, and from what the seed companies say about their own seed.
What farmers harvest today can be different. Newer harvest records, the season, the place, the soil, the water and the care all move these numbers over time.
So use them to compare varieties, not as a promise for your field. Ask your seller or your agriculturist how the variety did on farms near you in the last few seasons.
