Studies on rooting of hardwood stem cuttings using rooting media on Japanese persimmon (Diospyros kaki L.) Cv. Fuyu, treated with different concentration of indol-3-butyric acid

The present propagation study has been attempted to enumerate the rooting response of Hardwood stem cuttings of Persimmon (Diospyros kaki L.) cv. Fuyu. The different concentrations of IBA as, 1500 ppm, 3000 ppm, 4500 ppm and 6000 ppm respectively along with control by soaking method for 10 seconds. Later the cuttings were placed in rooting media, sandy soil and farm yard manure (FYM) in ratio of 1:1, 1:2 and 2:1 with filled in polythene bags. The maximum rooted cutting (64.40%) were recorded on 1:2 soil and FYM + 6000 ppm IBA treatment. The length of longest root obtained maximum in the same treatment i.e. 1:2 soil and FYM + 6000 ppm IBA, reached up to 8.00 cm. Significantly maximum number of primary roots per cutting (8.17) was found in cuttings planted in 3000 ppm IBA + 1:2 soil. Significantly maximum number of secondary roots per cutting (18.80) was found in the cuttings planted in 6000 ppm + 1:2 soil and FYM. Significant effect on length of shoot of rooted cutting, the maximum length of shoot (11.27 cm) was recorded in treatment (1:2 soil and FYM + 6000ppm IBA). Maximum fresh weight of roots per plant (1.36 g) and maximum dry weight of roots per plant (0.16 g) was found in the cuttings planted in 1:2 soil and FYM + 6000 ppm IBA. As conclusion is observed that the persimmon Interaction of IBA treatments and rooting media were also found significant for many of the parameters. The treatment combination (1:2 soil and FYM + 6000ppm IBA) was found to be significantly superior for many of the root parameters.
