ABSTRACTThe objective of this experiment was to determine the effect of concentration of nutrient solution on growth and yield of vetiver (Vetiveria zizanioides (L.) Nash) Verina 2 variety using Hydroponic Floating System Technology (HFST). This experiment was conducted in the greenhouse of Cikabayan Bawah, Experimental Farm IPB, with elevation of 240 m above sea level (asl) from December 2013 until February 2014. The experiment was based on a randomized complete block design which consisted of two experiments: (1) a plant without root cutting (3 replicates), (2) plants with root cutting (6 replicates), with one factor and three-levels: 200, 400, and 800 nutrient solution concentrations. The results sh...
