The field experiment conducted to study the effect of plant growth regulators (NAA, GA3 and BA at 50, 100 and 200 ppm and Ethrel at 300, 750 and 1000 ppm) and water as control on growth and herbage yield of palmarosa Cv Trishna during 2001 - 2002 revealed that foliar spray of GA3 200 ppm thrice at monthly intervals starting from 30 days after transplanting can be considered for obtaining higher herbage yield, essential oil content and oil yield of palmarosa. The plant height (284.86 cm), number of tillers per plant (43.46) and number of leaves per tiller (9.87) were significantly influenced by GA3 200 ppm solution.
