Black rice produces black which contains a lot of nutrients for the body, but there is still not much research done in increasing growth and productivity rice. The purpose this study was to determine level increase after addition phosphorus silica fertilizers varieties. experimental location Palir Village, Tengah Tani District, Cirebon Regency with height four 9 m above sea level. type soil alluvial pH 6. experiment carried out March-August 2019. This used factorial RAK consisting SP36 (P) fertilizer dosage SipadiHS (S) Silica dosage. consists P1 (50 kg ha-1) P2 (100 P3 (150 while S0 (without silica), S1 ha-1), S2 (200 S3 ha-1). results showed that an interaction variable plants aged 56 DAS P2S3 P3S3 treatments number tillers P2S1 treatment. Meanwhile, phosphate independently affected observations plant at age 28 42 DAS, Shoot Root Ratio DAS. Keywords: rice, SP36,
