Abstract: The present investigation entitled “Response of sampling time and auxins concentration on rooting of Chrysanthemum local Cv. Chandamama Yellow”was carried at Floriculture Research Station, (Agricultural Research Institute) Rajendranagar, Hyderabad during August 2018 to January 2019. The experiment was laidout in factorial concept with completely randomized block design in three replications. The experiment was executed with an objectives to study the effect of sampling time and auxins concentration on rooting ability of Chrysanthemum. The cuttings were taken in three different months of August, September and October and treated with different auxins concentration of IBA (50 ppm, 100 ppm, 250 ppm and 500 ppm), NAA (50 ppm, 100 ppm, 250 ppm and 500 ppm) and Rootex-1 powder to study rooting ability. The study revealed that significant differences were recorded in Chrysanthemum Cv. Chandamama Yellow. Among different sampling times, the cuttings taken in August recorded minimum days taken to emergence of sprouting, (20.17 days), maximum number of nodes sprouted per cutting (1.22), maximum number of leaves per cutting at 15, 30 and 45 DAP (5.16, 8.21 and 12.59 respectively) minimum days taken to rooting (11.84 days), maximum root length (9.66 cm), number of roots per cutting (16.91), rooting percentage (90.63 %), survival percentage (87.42 %), fresh weight of roots (0.63 g), dry weight of roots (0.09 mg) is observed in nursery condition similarly in field condition also maximum survival percentage (84.64 %), plant height (20.56 cm) , number of branches per plant (5.65), length of branch (21.34 cm) is observed in the month of August compared to other two monthly sampling period. Among different auxins concentration minimum days to emergence of sprouting (18.68 days), maximum number of nodes sprouted per cutting (1.84), maximum number of leaves per cutting at 15, 30 and 45 DAP (6.44, 8.72 and 14.44 respectively), survival percentage (89.95 %) was recorded with rootex-1 powder and minimum days taken to rooting (10.56 days), maximum root length (11.03 cm), maximum number of roots per cutting (20.56), rooting percentage (92.00 %), fresh weight of roots (0.95 g) , dry weight of roots (0.13 mg) was recorded with IBA 500 ppm in nursery condition. In field condition maximum survival percentage (84.34 %), plant height (26.41 cm), maximum number of branches per plant (5.78), length of branches (21.75 cm) was recored with Rootex-1 powder. Among different treatment combinations i.e., sampling time and auxins concentration, minimum days taken to sprouting (14.37 days), maximum number of nodes sprouted per cutting (2.08), maximum number of leaves per cutting at 15, 30 and 45 DAP (6.81, 9.85 and 15.37 respectively), survival percentage (98.26 %) is observed with August + Rootex-1 powder and minimum days taken to rooting (8.20 days), maximum root length (11.07 cm), maximum number of roots per cutting (22.47), rooting percentage (96.33 %), fresh weight of roots (1.26 g) , dry weight of roots (0.20 mg) was recorded with cuttings taken in August + IBA 500 ppm at nursery condition and maximum survival percentage (94.54 %), plant height (33.33 cm), maximum number of branches per plant (7.20), length of branches (28.20 cm) was recorded with August+Rootex-1 powder at field condition. The data on the economics of sampling time with different auxins concentrations showed that Rootex- powder (1.91) and IBA 500 ppm (1.54) in the month of August recorded the highest benefit cost ratio over other treatments. From these results, it is found that cuttings treated with Rootex-1 powder increased vegetative growth with good survival ability from the cuttings taken in the month of August and cuttings treated with IBA 500 ppm in August increase root growth, root number, rooting percentage, root fresh weight and dry weight when compared to all other treatments. It can be concluded from the present investigation, the cuttings taken from August month treated with Rootex-1 powder and IBA 500 ppm can be recommended for better survival ability, vegetative characters and rooting parameters.
