Rainfed rice fields from the air, the kind of farm PSB Rc 98 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 PSB Rc 98 yield?

On average it gives 2.6 tonnes per hectare. That is about 52 cavans of 50 kilograms of palay. It sits below the average of the 25 rainfed lowland inbreds on the list, which is 3.4 tonnes. But the top yield, 4.5 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 116 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.

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.

Amylose decides how rice cooks. With high amylose, expect rice that is firm and dry, and it hardens as it cools. 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 lowland that depends on the rains. So wait until the rains settle before you sow the seedbed, then transplant into the puddled 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 dry direct seeded, transplanted or wet direct seeded.
