Abstract:
The present investigation entitled “Studies on effect of different concentrations of IBA and length of cuttings on rooting and shoot growth performance in dragon fruit Hylocereus spp. - red flesh with pink skin under Telangana conditions” was carried out under open field conditions at College Farm, College of Horticulture, Rajendranagar, Hyderabad, from December 2020 to March 2021.The experiment was laid out in Factorial Completely Randomized Design with fifteen treatments replicated thrice. Treatment consisted of five levels of IBA, Control, 4000 ppm, 5000 ppm, 6000 ppm and 7000 ppm and three levels of length of cuttings 10 cm, 15 cm, 20 cm. The significant effect of the IBA and length of cuttings were observed for rooting and shooting behaviour. Indole butyric acid had significant effect on rooting and shooting performance over control. Among various concentrations of IBA @ 7000 ppm showed better results and among various cutting lengths 20 cm showed superior results and viz., earliest shoot initiation, maximum shoot growth, individual shoot length, number of new shoots per cutting, average number of roots per cuttings, individual root length, fresh weight of roots, dry weight of roots, survival percentage of rooted cuttings. Comparatively, minimum values of rooting and shooting parameters was found in control and cutting length of 10 cm.
