The treatment consis of a1 (450 g/polybag), a2 (569 g/polybag), a3 (678 g/polybag), u1 (20%), u2 (40%) and u3 (60%). The variables observed in the research number of leaves (sheet), plant fresh weight(g), root volume (cm3), plant dry weight (g), and root dry weight (g). The results showed that there was an interaction between rice husk ash and cow urine give a significant effect to the variables of root volume, plant dry weight and root dry weight. The best combination of giving rice husk ash and cow urine is a2u2 treatment, namely 569 g of rice husk ash and 40% cow urine.
