Results of research indicates that : (1) Fertilization dosage with fertilizer SP36 influentially very significant to weight total fresh plant, weight total dry plant, number of seeds per cob, weight dry minner per plant, weight dry minner per plot and weight dry minner per 100 seeds. (2) Fertilization dosage with buffalo manure influentially significant to hight of plant and hight of 100 seeds (3) Interaction between fertilization dosage with fertilizer SP36 and buffalo manure influentially significant to hight of 100 seeds. (4) Highest dry minner seeds weight 5,467 Kg/plot (9,719 ton/Ha) obtained at treatment of P2K2 combination of fertilizer dosage SP36 150 Kg/Ha with buffalo manure 15 ton/Ha, and lowered by 3,833 Kg/plot (6.6614 ton/Ha) obtained at treatment of P0K2 combination of fertilizer dosage SP36 0 Kg/Ha with buffalo manure 15 ton/Ha
