The experiment was conducted experimentally by using Factorial Random Design (RAL) consisting of 2 factors, the first factor consisted of 2 interval levels (cc / L) ie 3 days and 6 days and second factor: Nitrogen fertilizer with 4 dosage (g / plant) ie 3 g / plant, 6 g / plant, 9 g /. The data obtained were analyzed using Duncan's multiple-range test at 5% level. Interval of young coconut water and dose of urea fertilizer give significant effect to shoot diameter, shoot length, leaf number and leaf rubber seed stum, but not significant effect on shoot growth time. Provision of young coconut water at intervals of 3 days and dose of urea 9 g / plant fertilizer, can produce bud diameter, leaf number and leaf area.Keywords: Coconut Water Interval, Urea Fertilizer, Growth and Development of rubber seedlings.
