Roja Rambutan (NSIC Rm 06): Fruit and Tree Characteristics
Roja is a registered rambutan variety, also sold or known as NSIC Rm 06. It was registered with the National Seed Industry Council in 2003 as NSIC 2003 Rm 06. Mario Tenorio bred it. Its record notes a yield of 70 to 80 kg.
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.

When does it bear, and how much?
A registered tree variety is described from its mother tree, not from trial plots. The mother tree of Roja was about 15 years old and about 25 meters tall when it was registered. Its record notes a yield of 70 to 80 kg. It bears every year, with fruit in July September. A grafted or marcotted tree bears years sooner than one grown from seed, and its yield climbs as the tree grows.

Where and when to plant Roja rambutan
Pick a registered selection whose flesh comes off the seed cleanly, which buyers pay more for. Plant budded trees. A registered tree variety is a selection from one proven mother tree, and only grafted, budded or marcotted plants carry its traits. A seedling grown from its seed can turn out quite different. So buy from a nursery accredited by the Bureau of Plant Industry, and ask which mother tree the scions came from. Before planting, get the field ready with our guide: Pagtatanim ng puno.
