Pruning influences growth of new shoots, flowering, and fruiting in rambutan. This study aimed to determine the appropriate canopy size of rambutan (local cultivar of BPI accession - DES 001) after pruning relative to yield. After 4 years of observation, rambutan trees cutback at 3-m space between canopies significantly produced more fruits (121.15 kg/tree) compared with those cutback 2-m space between canopies, cutback 2.0-m space between canopies at 3 m height from the ground, and no pruning, the yield of which ranges from 85.58 to 110.43 kg per tree. However, there was no significant difference among pruned and unpruned trees in weight of fruits per cluster, number of fruits per cluster, and weight per fruit. Cutting back rambutan branches at 3-m space between canopies was recommended for a rambutan orchard with a planting distance of 7 m x 7 m or more between trees. Since canopies overlap by 0.39 m on the 4th year, pruning could be done at 4-year interval right after harvesting
