Low fertility is one of the issues in Inceptisols. One solution to solve this issue by provide a combination of soil conditioners containing organic matter and N, P, and K fertilizers as available nutrient elements to optimize soil fertility, thus improving the quality and quantity of rice. This experiment aims to determine the best dosage of the combination of soil improvement and N, P, and K fertilizers for K-potential, K-uptake, and rice crop results on Inceptisols from Jatinangor. The experiment was conducted from July to December 2023 at the Soil Chemistry and Plant Nutrition Laboratory Experiment Garden, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor, Sumedang. The research design used was  Completely Randomized Block Design (CRBD) consisting of eight treatments and four replications, namely: control; N, P, K dose recommendation; soil improver; ½ soil improver+ ¾ dose of N, P, K; ¾ soil improver+ ¾ dose of N, P, K; 1 soil improver+ ¾ dose of N, P, K; 1½ soil improver+ ¾ dose of N, P, K; and 1 soil improver+ 1 dose of N, P, K. The results of the experiment indicate that the treatment of 1½ soil improver+ ¾ dose of N, P, K can provide the best influence in increasing K-potential content, K-dd, K-uptake, and rice crop result (number of grains per panicle, 100-grain weight, and milled rice weight) in Inceptisols from Jatinangor.
