BS 9890 Corn: Yield, Maturity and Characteristics
BS 9890 corn is a yellow hybrid corn variety. It was registered with the National Seed Industry Council in 1997 as NSIC 1997 Cn 85. Bioseed Research bred it. It takes 95 to 103 days from planting to the harvest of dry grain, with 6.68 tonnes per hectare on average in the trials.
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 BS 9890 corn
It is recommended for Luzon and Mindanao in the dry season. 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.
