Var 6 Corn (IPB Var 6): Yield, Maturity and Characteristics
Var 6 corn is a white open pollinated corn variety, also sold or known as IPB Var 6 or IPB Variety 6. It was registered with the National Seed Industry Council in 2008 as NSIC 2008 Cn 224. IPB,College, Laguna bred it. It takes 101 to 105 days from planting to the harvest of dry grain, with 5.84 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.

How long does it take, and how much does it yield?
Var 6 corn takes 101 to 105 days from planting to the harvest of dry grain. That is about the average of the 28 white open pollinated corn varieties with a day count, 103 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 5.84 t/ha beats the average of its group, 5.36. It sits in the top 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. Its seller gives about 101 (wet season) to 105 (dry season) in national trials.
Once you know the day count, anee.io dates every task from each lot's own planting day, with the growth stages and weather beside it.
Is it resistant to pests and diseases?
| Pest or disease | Rating | What it means |
|---|---|---|
| Corn borer | Resistant | Held up well |
| Rust | Resistant | Held up well |
| Stalk rot | Resistant | Held up well |
| Corn earworm | Resistant | Held up well |
It showed no weak spot in the ratings on record. Still, a resistant variety can break down when a new strain or pest population comes, so keep scouting. Read up on Asian corn borer, Corn rust, Corn stalk rot, Corn earworm.
The pests and diseases that hit corn fields most often: Asian corn borer, banded leaf and sheath blight, Corn downy mildew, Corn ear rot, Corn planthopper. Our pest finder and disease finder help you name what you see.
What the grain is like
Its ears grew about 13.86 cm long in the trials. The shelling recovery was 76 percent, the share of the ear weight that comes off as grain. A higher share means more grain from every sack of ears. Against lodging it rated resistant, so it stood up well when wind and rain pushed the plants.
What its seller and farm sources say
- Yield: National tests averaged 5.84 t/ha in Luzon, 5.45 in the Visayas and 4.47 in Mindanao, 4.1 t/ha on farmers' fields over four seasons.
- Season: Wet and dry.
- Where: Registered for Luzon and the Visayas.
- White flint grain eaten as corn grits.
- Quality protein maize: about two thirds more lysine than ordinary corn.
- Yield close to commercial white hybrids.
- Yields poorly under drought, IPB is selecting for stress tolerance.
- Registry rates it resistant to lodging, corn borer, rust, stalk rot and earworm.
Why farmers know it: over 45,000 bags of seed went out through DA field offices, LGUs and NGOs by 2018, DA paid IPB to multiply it as a rice extender (Inquirer). 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 Var 6 corn
It is recommended for Luzon and the Visayas 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.
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.
