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?

USM Glut 1 corn takes 98 to 102 days from planting to the harvest of dry grain. That is about the average of the 19 glutinous open pollinated corn varieties with a day count, 97.1 days. A shorter crop frees the field sooner and dodges more of the weather, while a longer one often fills more.

Its average yield of 4.17 t/ha trails the average of its group, 5.09. It sits in the lower quarter of its group. One tonne of shelled corn fills about 20 sacks of 50 kilograms. Trial yields come from well managed plots, so your own will depend on water, fertilizer, pests and timing.

What the grain is like

Its ears grew about 14.06 cm long in the trials. The shelling recovery was 77.13 percent, the share of the ear weight that comes off as grain. A higher share means more grain from every sack of ears.

Where and when to plant USM Glut 1 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.

Before you buy seed

  • Buy sealed packs or tagged sacks from an accredited dealer, and check the packing date and germination rate.
  • Ask your municipal agriculturist or nearby farmers how it did in your area last season.
  • Try it on a small area first, beside the variety you usually plant, before you switch the whole farm.
  • Write down the planting day, inputs and harvest, so you can compare varieties on your own ground. anee.io keeps these records for you.
