It takes 104 to 108 days from planting to the harvest of dry grain, with 5.16 tonnes per hectare on average in the trials.

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.

Where and when to plant South Cotabato Improved Tiniguib corn
It is recommended for 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.
