Abstract
The present study entitled “Propagation Studies in carnation (Dianthus caryophyllus)” was carried out with carnation cv. Gaudina during 2017-18 at Centre for Quality Planting Material, CCS Haryana Agricultural University, Hisar. Seven rooting media i.e. river sand (control), coco peat, vermicompost + cocopeat + river sand (1:1:1), vermicompost + cocopeat (1:1), vermicompost + river sand (1:1), cocopeat + river sand (1:1) and cocopeat + vermiculite + perlite (3:1:1) with three IBA concentrations (0, 100, 200 ppm) were evaluated. The experiment comprised of twenty one total treatments, each having three replications and was laid out in CRD (in nursery) and RBD (in field study).
The study revealed that among the different rooting media studied, cocopeat + river sand (1:1) rooting media was found best for maximum survival percentage of carnation cuttings, rooting percentage, number of primary roots per cutting, root length, survival percentage of rooted cuttings in field, plant height, number of leaves per cutting at transplanting, height of rooted cuttings at the time of transplanting, number of floral buds per plant, number of flowers per plant, diameter of flower, stalk length of flowers, minimum days to initiation of first flower bud and minimum number of days to 50 percent flowering. Among the different IBA concentrations, carnation cuttings treated with 200 ppm IBA rooting hormone was found the most effective and significant for all the observations recorded. The interaction effect of different rooting media and IBA concentrations was also found significant and best results were obtained with cocopeat + river sand (1:1) rooting media with 200 ppm IBA concentration.
