Abstract

he purpose of this research is to get the dose for the growth and production of Jatropha curcas L. at the various dose of Nitrogen (N), Phospat (P), Kali um (K) fertilizer. The research was conducted at Agro Techno Park. Indralaya, in December 2006 until February 2007. Jatropha in Agro Techno Park, its around five months given the treatment as Urea fertilizer, SP-36, and KCI as N, P, K source. Its amount is matched to the fixed treatment. The method of this research was Randomized Block Design with six treatments and four replications. The treatment consisted control (without fertilizer) and five combination N, P and K fertilizer. The treatment are PO= contol , Pl = (50 Urea + 25 SP 36 + 16KCI) kg.ha·1, P2 = (100 Urea+ 50 SP 36 + 32 KCI) kg.ha·', P3 = (150 Urea+ 75 SP 36 + 48 KCl) kg.ha·1, P4 = (200 Urea + 100 SP 36 + 64 KCl) kg.ha·1, PS= (250 Urea+ 125 SP 36 + 80 KCI) kg.ha-1• In this research the variables were tested : plant height (cm), the number of leaves, shoot diameter, shoot volume (m3), the number of shoot, and the pod dry weight (g). The result of this research indicated that 125 g Urea, 63 g SP36, 40 g KCl per plant or 115 Kg, 5 Kg, 17 Kg K per hectar fertilizer produced high plant height, the number of leaves, shoot diameter, and shoot volume. 50 g Urea, 25 g SP36, 16 g KCI per plant or 46 Kg N, 2 Kg P, 8 Kg K per hectar fertilizer produced number of shoot and hjgh pod dry wejght per plant. The plant height, the number of leaves, shoot diameter, shoot volume variables positive correlation with pod dry weight.
