Effect of irrigation and nitrogen on herbage, oil yield and water use of lemongrass (Cymbopogon flexuosus) on alfisols
Published online by Cambridge University Press: 01 March 1999
Abstract
A field experiment was conducted with lemongrass (Cymbopogon flexuosus) at Bangalore, India during 1993–95 under three oil moisture regimes (0·75, 0·50 and 0·25) irrigation water:cumulative pan evaporation (IW:CPE) ratios and four rates of nitrogen application (0, 50, 100 and 150 kg ha−1). The soil moisture regime maintained at 0·75 IW:CPE ratio significantly increased crop growth characters such as plant height, leaf area index, herbage and essential oil yields, compared with those having 0·25 and 0·50 IW:CPE ratios. An application of 100 kg N ha−1 was found to be optimal for crop yield. Oil content and quality of oil were not affected by irrigation and nitrogen rates.
