This study aims to determine the granular compost and phosphate to inceptisol on availability soil phosphate, phosphate uptake and maize (Zea mays L.). The materials used in the research were compost granular, phosphate, and maize. This study used a completely randomized design with 9 treatments and 3 replications consisting of treatment KGES0= Control, KGES1= 40 t ha −1 KGES2=80 t ha −1 . The second factor was the SP-36 (P) fertilizer also with three variations, e.g. P0 without fertilizer P (control); P1 = 120 kg P ha −1 , P2 = 240 kg P ha −1 . Sago pith waste granular compost 80 t ha −1 combined with phosphate fertilizers 240 kg P ha −1 can increase soil pH to 6.7 and available phosphate that resulted in plant roots are capable of absorbing phosphate properly, so that the results of the dry corn grain weight to 7.85 t ha −1 also increased. Besides, granular compost 80 t ha −1 and phosphate 240 kg P ha −1 was also able to independently increase the P-uptake of plants by 0.168% and 0.169%, respectively. 80 t ha −1 of compost and phosphate 240 kg P ha −1 was the best dose combination to improve the results of the dry corn grain weight yield at 7.85 t ha −1 .
