Effect of the different rooting media and IBA concentrations on survival percentage and root parameters of carnation (Dianthus caryophyllus) cuttings CV. Gaudina

The present experiment was conducted to study the effect of different rooting media and IBA concentrations on rooting of carnation cuttings cv. Gaudina under semi-climate controlled greenhouse conditions, during 2017-2018 and the experiment was conducted in Completely Randomized Design (CRD). All the rooting media and IBA concentrations studied recorded superior rooting parameters over control. Among the rooting media studied, cocopeat + river sand (1:1) and among the IBA concentration, 200 ppm IBA was found the best. Within the interaction treatments, the best combination was found with the cocopeat + river sand (1:1) rooting media with 200 ppm IBA concentration which recorded highest survival percentage of cuttings (93.33%), rooting percentage (93.33%), number of primary roots per cutting (6.93) and longest root length (69.47 mm).
