Ripe palay heads, the harvest a hybrid like NSIC Rc 588H is bred to fill

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 588H yield?

On average it gives 6.6 tonnes per hectare. That is about 132 cavans of 50 kilograms of palay. It sits below the average of the 180 irrigated lowland hybrids on the list, which is 6.9 tonnes. But the top yield, 12.7 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 115 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 sheath blight, tungro. 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 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. For the right month in your province, see the best time to plant rice.
