What its seller and farm sources say

  • Where: Marginal uplands, used in Mindanao, the Visayas and Isabela.
  • Bred from CIMMYT Pop 20.
  • The most stable and highest yielding OPV in marginal upland trials, though below commercial hybrids.

Why farmers know it: Bohol's provincial government bought 750 sacks for its corn farmers in 2018, earlier seed went to about 2,000 upland farmers. Check these against what farmers near you have seen, because the same variety can do differently from one town to the next.

Where and when to plant USM Var 10 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.
  • 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.
