NSIC Rc 582 (Tubigan 47) Rice Variety: Yield, Maturity and Characteristics
NSIC Rc 582 is an inbred rice variety for irrigated lowland, known locally as Tubigan 47. The NSIC approved it in 2019. It matures in about 109 days and averages 5.6 tonnes per hectare, with a top yield of 8.5 tonnes in 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 much does NSIC Rc 582 yield?
On average it gives 5.6 tonnes per hectare. That is about 112 cavans of 50 kilograms of palay. It sits above the average of the 118 irrigated lowland inbreds on the list, which is 5.2 tonnes. But the top yield, 8.5 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 109 days from sowing to harvest, and about 104 days if you seed it directly. 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?
| Pest or disease | Rating | What it means |
|---|---|---|
| Rice blast | Intermediate | Took a middling share of damage |
| Bacterial leaf blight | Intermediate | Took a middling share of damage |
| Tungro | Intermediate | Took a middling share of damage |
| Brown planthopper | Intermediate | Took a middling share of damage |
| Green leafhopper | Intermediate | Took a middling share of damage |
| Sheath blight | Intermediate | Took a middling share of damage |
| Stem borer | Intermediate | Took a middling share of damage |
It showed no weak spot in its ratings. Still, a resistant variety can break down when a new strain of a disease or a new pest population comes. So keep scouting, and use our pest and disease finders when something looks wrong.
Grain and eating quality
| Measure | Value | Class |
|---|---|---|
| Amylose | 17.2 percent | Low |
| Milling recovery | 68.7 percent | Grade 1 |
| Head rice | 39.8 percent | Grade 2 |
| Chalky grains | 18.6 percent | Not graded |
| Grain length | 6.7 mm | Long |
| Grain shape, length to width | 3.1 | Slender |
Amylose decides how rice cooks. With low amylose, expect rice that is soft. 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 irrigated lowland, where you control the water. Level the field well so the water stands evenly, and plant together with the farms around you, so pests cannot move from field to field. Our guide to rice land preparation shows each step. It is recommended for the dry season and the wet season. You can plant it transplanted or wet direct seeded.
