DEKALB®9919S VTDoublePro RIB Complete Corn (DK 9919S): Yield, Maturity and Characteristics
DEKALB®9919S VTDoublePro RIB Complete corn is a yellow GM hybrid corn variety, also sold or known as DK 9919S or Dekalb 9919S. It was registered with the National Seed Industry Council in 2020 as NSIC 2020 GMCn 72. Bayer Crop Science bred it. It takes 105 to 107 days from planting to the harvest of dry grain, with 8.5 tonnes per hectare in the trials (9.21 in Luzon, 7.79 in Mindanao).
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.

How long does it take, and how much does it yield?

Where and when to plant DEKALB®9919S VTDoublePro RIB Complete corn
It is recommended for Luzon and Mindanao. 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.
