Abstract: The objective of this study is to find out the optimum rate of potassium fertilization in Inceptisols Dramaga. The experiment was conducted at Cikabayan University Farm from March to July 2014. This study was arranged in Randomized Complete Block Design one factor with five K fertilization rates, ie 0X (0 kg K2O ha-1), ¼ X (193.09 kg K2O ha-1), ½ X (386.19 kg K2O ha-1), ¾ X (579.29 kg K2O ha-1), and 1X (772.39 kg K2O ha-1). Potassium fertilizer was applied in three applications at 3, 6, and 9 weeks after transplanting. The results showed that K fertilization increase plant height, leaf number, weight per plant, fruit weight, fruit diameter, fruit length, marketable yield per plot, unmarketable yield per plot, marketable yield per hectare, and unmarketable yield per hectare with linear response pattern. While the addition of potassium did not affect the time of anthesis and fruit ripening. The addition of potassium fertilizer also increase total yield per plot and total yield per hectare with quadratic response pattern. In the medium K soil content with the value of 146.2 ppm (Morgan) K recommendation for red chili in inceptisols Dramaga is 487.5 kg K2O ha-1.
