Technical Abstract: Eight rambutan (Nephelium lappaceum) cultivars grown on an Oxisol and Ultisol were evaluated for three years under intensive management at Isabela and Corozal, Puerto Rico, respectively. There were significant differences in number and weight of fruits per hectare between locations and years. Significantly more fruits were produced at Corozal (357,004 fruits/ha) than at Isabela (168,083 fruits/ha). Fruit yield at Corozal and Isabela was 11,357 and 5,111 kg/ha, respectively. At Corozal, varieties were not significantly different for number of fruit and yield per hectare. At Isabela, cultivar Gula Batus and R-162 produced significantly more fruits and higher fruit weight than other cultivars averaging 234,153 fruits/ha and 6,979 kg/ha, respectively. Cultivar R-156Y had the lowest yield at both locations. Cultivars R-156Y and Rongrien had fruit with significantly more pulp (58%) than other cultivars (47%). At both locations, significantly lower fruit soluble solids (Brix) values (19.1) were obtained from fruits of cultivars R-156Y and Gula Batus; there were no significant differences in Brix among the rest of the cultivars (20.2).
