Is a factorial experiment (3X4) with randomized completely block design, the first factors were nursery medium composition consisted of cattle manure, soil, and hull of rice, with volume ratio 3:1:1, 1:1:1, and 1:1:3. The second factors are NPK fertilizer dosage consisted of 0, 1, 3, and 5 g/seedling. The treatments were consisted 3 replication and each experiment unit consisted 10 seedlings. The results show that (1) blend of cattle manure, soil, and hull of rice with ratio 1:1:3 have sucsesful grafting persentage and dry weight of shoot higher than ratio 3:1:1 and 1:1:1, (2) NPK fertilizer dosage until 3 g/seedling unsignificant than control on root stock and entres diameter and dry wight of root and shoot; (3) There is no interaction beetwen seedling medium ratio and NPK fertilizer dosage to growth of physic nut seedling by grafting.Key words: grafting, nursery medium, NPK fertilizer, physic nut
