Abstract
The experiment entitled “Effect of growing media and plant growth regulators on root and shoot growth of dragon fruit cuttings” was carried out during the year 2019-20 at Centre of Excellence on Protected Cultivation and Precision Farming, “Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh. The experiment was laid out in” Factorial Completely “Randomized Design and replicated three times with 12 treatment” combinations of two factors, first factor was media i.e. M1 – Soil : Sand : Cocopeat : FYM (2:1:1:1) and M2 – Soil : Sand : Cocopeat : Vermicompost (2:1:1:1) and the second factor was plant growth regulator i.e. IBA @ 5000 ppm, IBA @ 7000 ppm, “NAA @ 100 ppm, IBA” @ 5000 ppm + NAA @ 100 ppm, IBA @ 7000 “ppm + NAA” @ 100 and control.
The study revealed significant difference among both media for different rooting and shooting parameters. Media, M2 – Soil : Sand : Cocopeat : Vermicompost (2:1:1:1) performed superior in all parameters viz. number of days taken to sprout initiation, average number of roots per cuttings, average length of root per cutting, root fresh weight, root dry weight, number of sprouts per cutting, length of shoot, shoot fresh weight, shoot dry weight, survival percentage and root to shoot ratio.
Among all plant growth regulator concentrations, IBA @ 7000 ppm was found to be the best with number of days taken to sprout initiation (35 days), average number of roots per cutting (18), average length of root per cutting (25.67 cm), root fresh weight (2.98 g), root dry weight (0.83 g), number of sprouts per cutting (1.72, 2.78, 3.64 and 4.22 at 30, 60, 90 and 120 DAP, respectively), length of shoot (9.42 cm, 12.78 cm and 18.28 cm at 60, 90 and 120 DAP respectively), shoot fresh weight (123.74 g), shoot dry weight (12.63 g), survival percentage (98.34%) and root to shoot ratio (0.93).
The interaction effect of media and plant growth regulators was significant in almost all growth parameters except average number of root per cutting and number of sprouts per cutting. In the present investigation it can be concluded that the dragon fruit cuttings treated with IBA @ 7000 ppm, grown in media M2 containing Soil : Sand : Cocopeat : Vermicompost (2:1:1:1) gave maximum response on the root and shoot growth parameters.
