Abstract:
A field experiment on “Study of different IBA levels on nursery behaviour of dragon fruit cuttings” was conducted at Experimental farm and Analytical laboratory, Department of Fruit Science, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during the year 2018-19 with objectives to study the effect of different IBA levels on rooting of cutting of dragon fruit cutting under Akola condition. To find out the effect of different levels on rooting of cutting of dragon fruit. The experiment was laid out in Completely Randomized Design (CRD) with six treatments which were replicated four times. The stem cutting of dragon fruit treated with Indole Butyric Acid (IBA), to study the introduction of dragon fruit were successfully grow in Akola condition. The results obtained during course of investigation are summarized in following paragraphs. The result reveals that, in respect of root growth parameter, maximum number of root (55.15), maximum root length (20.62 cm), root diameter (2.06 mm), average length of root (17.47 cm), fresh weight of root (2.09 g) length of longest root (24.23 cm), root volume (1.88 cc), average number of root (43.91 cm), dry weight of root (0.61g).This observations were found maximum at 2000 ppm IBA concentration .In respect of shoot growth parameter, Early sprouting (36.99 days), shoot length (24.39 cm), length of longest shoot (31.75 cm), shoot diameter (5.90mm), fresh weight of shoot (47.77 mm), dry weight (8.39 mm), number of sprouts per cutting (4.51mm) was observed maximum at 2000 ppm IBA concentration. From the above experiment application of IBA 2000 ppm was found to improve rooting, shooting and survivability (95.87%) of stem cutting in Dragon fruit and could be commercially used for propagation under Akola condition.
