AH Ultra 357 Corn (Ultra 357): Characteristics
AH Ultra 357 corn is a yellow yellow GM hybrid corn variety, also sold or known as Ultra 357 or Asian Hybrid Ultra 357. It is not a registered variety, so the facts here come from its seller and farm sources. It comes from Asian Hybrid Seed Technologies.
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.

Where and when to plant AH Ultra 357 corn
Start with the color your buyer pays for: yellow corn goes to feed mills, while white and glutinous corn go to the table. Next, pick between a hybrid, which yields more but needs new seed every season, and an open pollinated variety, whose seed you can save. Then match the island group in its recommendation, because trials in Luzon and Mindanao give different winners. Before planting, get the field ready with our guide: Land preparation for corn.
Before you buy seed
- Buy sealed packs or tagged sacks from an accredited dealer, and check the packing date and germination rate.
