Rainfed rice fields from the air, the kind of farm NSIC Rc 346 is meant for

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 much does NSIC Rc 346 yield?

On average it gives 3.3 tonnes per hectare. That is about 66 cavans of 50 kilograms of palay. It sits close to the average of the 31 rainfed lowland inbreds on the list, which is 3.2 tonnes. But the top yield, 6.2 tonnes, came from a trial with good water, seed and care. So plan your costs on the average, then work toward the top with the habits in our guide to raising rice yield per hectare.

How many days does it take to mature?

It takes about 105 days from sowing to harvest. Varieties of 100 to 120 days count as short duration and 120 to 140 days as medium, so this one counts as short duration. Then harvest when 85 to 90 percent of the grains turn golden yellow. Because the day count drives every task, anee.io counts it for you from each lot's own planting day, with the growth stages and weather beside it.

Is it resistant to pests and diseases?

Reactions in trials: R resistant, MR moderately resistant, I intermediate, MS moderately susceptible, S susceptible. Some carry a second rating in brackets.

So scout early for rice blast, bacterial leaf blight, tungro, sheath blight. When you see the first signs, check the guide before you spray, because the right timing saves more than an extra dose. If you are not sure what you see, our pest and disease finders help you name it from the damage.

Amylose decides how rice cooks. With intermediate amylose, expect rice that is soft but not sticky. In fact, Filipino taste has moved from high to intermediate and low amylose rice, because people want it softer. Head rice is the share of whole grains after milling. So a higher number means fewer broken grains and a better price at the mill.

Where should you plant it?

It suits rainfed fields that are seeded directly. So prepare the field when the first rains come, and seed it once the soil holds moisture. Our guide to land preparation for direct seeded rice shows how. It is recommended for the wet season. You can plant it dry direct seeded, transplanted or wet direct seeded.
