The present studies were on the effect of plant growth regulators on vegetative growth and flowering was carried out during 2010-2011 with 9 treatments and each 3 replications in a Randomized block design at Horticulture College and Research Institute, Dr.Y.S.R. Horticulture University, Venkataramannagudem, WestGodavri district. Among the vegetative parameters, the treatment GA3 at 100 ppm recorded maximum values for plant height and leaf length over other treatments. NAA at 250 ppm recorded the maximum number of leaves, leaf width and leaf area over other treatments. TIBA at 150 ppm recorded minimum plant height, number of leaves and leaf area. Among the floral parameters, TIBA at 150 ppm recorded minimum number of days to first floret appearance (82.56) and 50 percent flowering (90.93). Similarly BA at 100 ppm recorded maximum number of spikes per corm (1.40). However higher mean spike length (137.98 cm) and number of florets per spike (14.06) were recorded with GA3 at 100 ppm. The minimum spike length & number of florets were observed with TIBA at 150 ppm.
