【 摘 要 】

The study aimed to determine the appropriate dose of K-type fertilizer on the production and quality of IR-64 rice varieties in Entisols. The study was conducted on Entisols, Nglarang, Basin, Kebonarum, Klaten, Central Java, Indonesia. Randomized Complete Block Design (RCBD) was used with 2 factors and three replicates. Factor I: types of K fertilizer: KCl, ZK, and KNO3. Factor II: K fertilizer dose consists of four levels: 0, 50, 100 and 150 kg K2O ha-1. The results showed that the type of K fertilizer KCl, ZK, and KNO3gave similar effect on growth and yield of rice variety IR 64 on Entisols. Dose of K fertilizer increased the growth and yield of rice but an increased dose provides improved meaningful results. K fertilizer with a dose of 50 kg ha-1 K2O is the most efficient, with the agronomic efficiency for dry grain highest yield of 13.6 kg/kg K2O achieved by ZK fertilizer.
