ABSTRACT
A study on stevia (Stevia rebaudiana Bertoni) was carried out at the Department of Horticulture, University of Agricultural Sciences, GKVK, Bangalore during 2006-07 to assess the rooting performance of cuttings of different lengths in different seasons in Completely Randomized Design. The main treatments consisted of three seasons (kharif, autumn and summer) and two length of cuttings (6cm and 9cm) with three replications. The cuttings planted in kharif showed significantly early sprouting (12.52days), high rooting percentage (54.25%), better sprouting (3.10 sprouts per cutting and 20.96 leaves per cutting at 45 DAP) and rooting (18.62 roots per cutting) and also highest survival percentage (78.41%). The cuttings of 9cm length sprouted early (13.66days) with better sprouting (2.57 sprouts per cutting and 20.23 leaves per cutting) and rooting (51.32 per cent rooting) which also resulted in higher survival percentage (74.41) compared to 6cm long cuttings. The cuttings of 9cm length planted during kharif performed better with 56.48 per cent rooting and 81.05 per cent field survival.
