Boosting Rambutan Productivity through Improvements in Fruit Set

Download PDF

The rambutan (Nephelium lappaceum) is a tropical, evergreen tree native to the humid, tropical regions of Malaysia and Indonesia where the climate is reasonably predictable and production fairly consistent. In Australian growing conditions production has been poor and inconsistent from season to season.
Two factors known to contribute towards this problem are poor fruit set due to poor pollination and excessive fruit drop during fruit development prior to maturity. The combination of these factors has severely impacted the productivity of trees and limited the expansion of the industry. Variable production from year to year has also created problems in market development.
The rambutan industry has highlighted these issues as key production constraints in their strategic plan.
