This research objective was to find the optimum rate of potassium fertilizer for specific location of tomato cultivation in inceptisol Dramaga with high soil potassium content (231 ppm). The experiment was conducted at Cikabayan Teaching Farm IPB from July to October 2014. The experiment was arranged in Randomized Completely Block Design with four replications and single treatment factor which was potassium rate in five levels ie 0X (0), ¼X (152.2 kg ha-1), ½X (304.3 kg ha-1), ¾X (456.3 kg ha-1), and X (608.6 kg ha-1). The results showed that on high soil potassium content potassium fertilizer were not affect all of the measured variables, therefore K fertilization is unnecessary.
