Response of five galanga promising lines to fertilizationIndia galanga (Kaempferia galanga) is commonly used forhousehold consumption, medicines, food and drink supplement industriesas well as cigarette sauce. Increase in demand of this commodity fordomestic industries will raise the consumption of symplicia. Therefore,effort in increasing yield of the plant through cultivation techniqueimprovement, i.e. application of superior variety and fertilization, is worthto be accomplished. In this experiment five Galanga promising lines ofIndia galanga were subjected to organic and inorganic fertilizations atlow land latosol soil, Cileungsi, Bogor, West Java. Experiment was carriedout from October 2003 – August 2004 and arranged in randomized blockin factorial design, with two replications. First factor is the promising lines(V1, V2, V3, V4 and V5); factor II is fertilization packages (6 packages).Plot size of 4 x 1.2 m and plant spacing of 20 x 20 cm, were applied. Theresults showed that four of five tested promising lines yielded the sameresults of fresh and dry weight of rhizomes ranged from 62.27-70.22g/plant, and the dry weight was 16.95-19.33 g/plant respectively.Fertilization packages of dung manure 20 t/ha + urea 250 kg/ha + SP36200 kg/ha + KCl 200 kg/ha, or organic fertilizer by using dung manure 40ton/ha, are recommended. Application of fertilization package resulted indifferent response to the plant for their qualities. The essential oil contentof promising lines V3 belongs to the first grade of quality (2.03%), whilethe others are the second one (1.08-1.97%), with the yield of essential oilranged from 0.325 – 0.466 ml/plant. The nutrients uptake of the promisinglines to the applied technology package were 149.60 – 415.60 mg/plant ofN, 41.50 – 112.50 mg/plant of P, and 236.10 – 571.70 mg/plant of Knutrients
