In this study, the processing Guava, Five or six years old of Chung Sun Yueh Pa, and two chemicals, 46% Urea and 39.5% Ethrel, were used. The results from two-year experiments revealed that different applicationtimings and chemical concentrat onis were closely related to defoliation and production of processing guava under different climate conditions. New shoots were caused severe defoliation and injury, and productivity was also low when 25% urea was applied. 6.25% urea was the best concentration with 36.1% defoliation and only 20.3cm dieback on new shoot. Buds initiated again 12-14 days after spraying of 6.25% urea. Yield of year was 39.8kg per tree with a average of 94.8g per fruit in 6.25% urea treatment, resulting a 45-51% yield increase compared to other treatments. Difference of fruit quality between treatments was not significant.
