Abstract: Nine citronella genotypes were evaluated for growth parameters, herbage yield and essential oil content during 2012-2013 at KRC college of Horticulture, Arabhavi, Karnataka, India. There were two harvests in a year first harvest at 9month after harvesting and second at 3 month after first harvest. There was no significant report with respect to tiller number per plant at both the harvest whereas, maximum tiller per plant (87.13 & 106.40 first and second harvest respectively) was recorded in genotype Mandakini. The significant differences were obtained fresh herbage yield. The result revealed that at both the harvest total maximum yield (73.26 t/ha) was recorded in genotype Assam and total minimum yield (40.95 t/ha) was recorded in Java-2. Essential oil content (FWB) shows significant difference only at first harvest, mean of two years showed highest essential oil content (1.115%) in genotype Java-2, followed by in Bio-13 and Manjari (1.060 & 1.036%) and lowest essential oil content (0.593%) was in genotype Ceylon local.
