Grain and eating quality
| Measure | Value | Class |
|---|---|---|
| Amylose | 19.2 percent | Intermediate |
| Milling recovery | 70.3 percent | Premium |
| Head rice | 62.4 percent | Premium |
| Chalky grains | 9.7 percent | Grade 2 |
| Grain length | 6.8 mm | Long |
| Grain shape, length to width | 3 | Slender |
| Protein | 7.2 percent |
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. It is recommended for the dry season and the wet season. You can plant it wet direct seeded. It was tested and found suitable in Central Luzon and Cagayan Valley. For the right month in your province, see the best time to plant rice.
