Inceptisols are an order of soil that has great potential to be used as productive land for rice cultivation because of its wide distribution in Indonesia. However, this land order has low soil fertility so it is necessary to fertilize to increase soil fertility. Balanced fertilization with soil improvers and N, P, and K fertilizers can be applied to increase fertilization efficiency. This experiment aims to obtain the dose of soil improver and N, P, K fertilizer that has the best effect on P-potential, P-available, P-uptake, and rice yield. The experiment was carried out from July to December 2023 at the Soil Chemistry and Plant Nutrition Laboratory Experimental Garden, Faculty of Agriculture, University of Padjadjaran, Jatinangor, Sumedang. The experimental design used was a Completely Randomized Block Design (CRBD) with seven treatments and four replications consisting of control; N, P, K recommendations; soil improver; ½ soil + ¾ dose of N, P, K; ¾ soil improver + ¾ dose of N, P, K; 1 soil improver + ¾ dose of N, P, K; 1 ½ soil improver + ¾ dose of N, P, K; 1 soil improver + 1 dose of N, P, K. One dose of soil improver is 8000 kg ha-1, while one dose of N, P, K fertilizer is 350 kg ha-1 Urea, 50 kg ha-1 SP-36, and 50 kg ha-1 KCl. The experimental results showed that the treatment of 1 ½ soil improver + ¾ dose of N, P, K was the best treatment for increasing the weight of 100 grains.
