Balanced fertilization is one solution to support sustainable agriculture.This experiment was conducted to determine the study of potassium caused by balanced fertilization. The experimental method used a Randomized Block Design (RBD) single factor with ten treatments and three replications, so the total is 30 experimental plots. The ten treatments consisted of : without fertilizer (0), ½, 1, 1,5 and 2 doses of organic fertilizer + without fertilizer (0), ¼, ½, ¾ and 1 doses of anorganic fertilizer. The results of this experiments showed that there were significant effects on potencial K, exchangeable K, K uptake and yield of pakchoy from combination of organic fertilizer with anorganic fertilizer. The treatment 1½ dose of organic fertilizer + 1 dose of anorganic fertilizer produce the highest yield of pakchoy with 5.13 kg plot-1 (increase 100 % than control).Keywords: Azolla pinnata compost, litter, peat, solid biofertilizer
