Abstract

A field experiment was conducted for 2 years during the crop seasons of 1991-93 at Bangalore to study the effect
of 6 irrigation regimes (1.60, 0.80, 0.50, 0.40 and 0.30 Irrigation Water: Cumulative Pan Evaporation ratio) along with the
Control (no irrigation) on 3 lemongrass [Cymbopogon flexuosus (Steud.) Wats.] cultivars ('OD 19', 'Pragati' and
'Cauvery'). The moisture regime of 0.50 IW : CPE ratio gave significantly higher oil yield compared to 0.40, 0.30 and
control and was at par with 0.80 and 1 .60. Plant height, no. of tillers/plant and leaf area index increased up to 0.80 IW :
CPE ratio. Among the lemongrass cultivars 'Cauvery' gave significantly higher oil content (0.78%) and oil yield
(350 kg/ha).
