Davana (Artemisia pallens wall.ex.D.C.) is an important high valued annual aromatic herb of India belonging to the family Asteraceae. A field experiment was conducted at TamilNadu agricultural university, Coimbatore during rabi 2011 to study the influence of ratoon crop on growth, yield attributes and resultant seed quality of davana. The experiment was laid out with four different treatments viz., Stubbles cut at 5 cm height, Stubbles cut at 10 cm height, Stubbles cut at 15 cm height, Control (Normal crop) defoliation with the spacing of 15x7.5 cm and 125:125:75 NPK kg/ha were adopted in a randomized block design with five replications. Studies on ratoon crop revealed that defoliated seedlings improved the seed yield plot-1 (30.39 g), herbage yield plot-1 (980 g), germination (62%) and vigour index (148.8).
