The present investigation carried out to assess the field performance of crossandra flower var. Arka Shravya propagated through various cutting types (terminal and semi hardwood) and undole-3-butyric acid (IBA) treatments (100, 200, 300 ppm as a prolonged dip for 24h; 1000, 2000, 3000 ppm as a quick dip for 10 sec and 0 ppm as control) showed that the terminal cuttings pretreated with IBA quick dip @ 3000 ppm for 10 sec superior performance in terms of various growth parameters like plant height (76.40 cm), number of primary branches per plant (11.95), plant spread (1202.20 cm2), leaf area (1433.78 cm2) and total leaf chlorophyll content (68.62 SPAD units). The treatment also exhibited earlier spike initiation (11.00), first flower opening (17.00), days to 50 percent (19.50) and complete flowering (22.50) in crossandra var. Arka Shravya.
