Abstract

The influence of different foliar applications of urea on growth, essential oil accumulation in lemon grass (Cymbopogan flexuosus L.) was studied at the research area of medicinal and aromatic plants under department of Crop and Herbal Physiology during 2008 to 2009 to estimate the yield components, namely, plant height, tillers per plant, biomass yield, accumulation of essential oil, with treatment of different doses of urea, namely, 1, 1.25, 1.5, 1.75 and 2 g/plant compared to the untreated control. Foliar application of urea at 2 g/plant produced maximum plant height (92.7 cm), number of tillers per plant (106.05) and herb yield (357.1 g/plants) whereas maximum increase in essential oil content and leaf area was observed in treatment with 1.5 gm urea/plant as foliar application. Key words: Urea, foliar application, essential oils, lemon grass.
