This study was conducted in 1994 at the Experiment Station of Araponga, Minas Gerais, located in a region of Cwa - climate. The objective was to determine the effect of application of 7,8 g. i.a.L-1 hydrogen cyanamide plus 8,0 mL.L-1 mineral oil on persimmon trees cv. Rubi, and the effect of application dates (6/9, 6/30, 7/21, 8/11/1994). All the treatments using hydrogen cyanamide plus mineral oil promoted earlier bud burst, flowering and harvesting compared to the control, permiting fruit harvesting begining in december. The content of soluble solids and titratable acidity and fruit set increased with the application of hydrogen cyanamide plus mineral oil in 6/9. There was no significant difference for flesh firmness and average fruit weight.
