In satsuma mandarin (C. unshiu Marc. cv. Miyagawa), alternate bearing is frequently occurred. It is very difficult to control and maintain the optimum production because satsuma mandarin is a very sensitive citrus cultivar. We carried out the experiment to find out the effects of foliar application of gibberellic acid (GA₃) and machine oil emulsion mixture on flowering and fruit quality of satsuma mandarin grown on open field. The treatments were composed of control (no application), GA₃ (25, 50 and 100 mg?L<SUP>-1</SUP>), machine oil emulsion 100 times and mixture of GA₃ (25 and 50 mg?L<SUP>-1</SUP>) with machine oil emulsion 100 times on 16 year-old ‘Miyagawa’ satsuma mandarin on December 30, 2012. Foliar application of GA₃ during winter season led to a reduction of the flowering in the following year. GA₃ decreased flowering in dose dependant manner. However, application of GA₃ and machine oil emulsion (100 times-diluted mixture) inhibited effectively the flowering compared to GA₃ only. Also, flower-leaf ratio was significantly decreased by the application of GA₃3 25 (0.54) and 50 (0.41) mg?L<SUP>-1</SUP> with machine oil emulsion mixture in comparison to GA₃ 25 (0.86) and 50 (0.60) mg?L<SUP>-1</SUP> only. The number of leaves per fruit increased in application of GA₃ and machine oil emulsion mixture as concentration of GA₃ increased. Fruit weight and sugar-acid ratio also increased in comparison to the control whereas fruit size, soluble solid content and acidity remained unchanged. From the results, it was suggested that GA₃ application can reduce the number of flowers on the alternate bearing of satsuma mandarin. Moreover, application of GA₃ (25 and 50 mg?L<SUP>-1</SUP>) with machine oil emulsion 100 times mixture can reduce the flowering effectively without altering fruit maturity and soluble solid contents. Therefore, it can be concluded that the application of GA₃ 25 and 50 mg?L<SUP>-1</SUP> with machine oil emulsion 100 times might be useful in controlling alternate bearing in satsuma mandarin.
