Effects of paclobutrazol on the flowering, fruit setting and fruit quality of neck orange was observed at the Faculty of Natural Resources field during January to October 1987. The design was RCB with 6 treatments, 3 replication, i.e, leaf spray with 1,000, 2,000 ppm paclobutrazol; soil drench with 1, 2.5 and 5 g/plant and control. All treatments of paclobutrazol increased percent of fruit set and the number of harvested fruits significantly. The 2.5 g/tree soil drenched gave the highest percent of fruit set (28 %). One g/tree soil drench gave the highest number of harvested fruit, 68 fruit/tree average. The rate of 1,000 ppm spraying showed significantly fresh and dry weight of fruit different from the other treatments. However, paclobutrazol did not affect percent soluble solid, fruit size, fruit rind, sugar and acid content of the neck orange.
