The availability of Inceptisols nutrients is not sufficient for organic farming activities in rice cultivation, therefore it can be optimized by adding organic fertilizers, one of which is manure. The study aims to determine the effect of various manure types on the availability and uptake of P and K nutrients of rice in Inceptisols. The study used a single-factor Randomized Complete Group Design with 10 treatments: T1 = control; T2 = NPK 200 kg/ha; T3 = cow manure 10 tons/ha; T4 = chicken manure 10 tons/ha; T5 = goat manure 10 tons/ha; T6 = quail manure 10 tons/ha; T7 = NPK 100 kg/ha + cow manure 5 tons/ha; T8 = NPK 100 kg/ha + chicken manure 5 tons/ha; T9 = NPK 100 kg/ha + goat manure 5 tons/ha; T10 = NPK 100 kg/ha + quail manure 5 tons/ha repeated 3 times with experimental plots measuring 2.5 m×4 m. The results showed that quail manure applied singly or in combination with NPK fertilizer had a substantial effect on available P, exchangeable K, and plant P and K uptake. This is determined by high P and K nutrient contents in manure and has a lower C/N ratio than other manures. The results showed that quail manure was able to increase the availability and uptake of P and K nutrients of rice plants in Inceptisols. Thus, quail manure can be a recommended organic fertilizer for rice cultivation
