Abstract

The optimum dosage of N, P, and K fertilizer has not been knownyet and it USAge was still varied. The research aim is to obtain an optimalcomposition of N, P, and K fertilizer that could increase productivity ofvetiver crop. The researsch has been conducted in Sukakarya Village,Garut, from January 2009 to December 2010. The research was arrangedin randomized block design, with 3 replications and N, P, and K fertilizercombination treatments i.e.: (1) Control; (2) 100 kg SP-36 + 75 kg KCl;(3) 100 kg ZA + 75 kg KCl; (4) 100 kg ZA + 50 kg SP-36 + 75 kg KCl;(5) 100 kg ZA + 100 kg SP-36 + 75 kg KCl; (6) 100 kg ZA + 100 kg SP-36 + 150 kg KCl; (7) 100 kg ZA + 100 kg SP-36; (8) 200 kg ZA + 100 kgSP-36 + 75 kg KCl; (9) 200 kg ZA + 100 kg SP-36 + 150 kg KCl.Harvesting was done at 12, 14 and 16 months after planting (MAP). Theresult showed that the dose of 100 kg ZA + 75 kg KCl produced vetiver oil52,59 and 67,78 kg/ha (12 and 14 MAP). Meanwhile the dose of 200 kgZA + 100 kg SP-36 + 75 kg KCl produced 67,76 kg/ha (16 MAP),respectively. vetiverol content were more than 50%.
