PERFORMANCE OF IBA CONCENTRATIONS FOR ROOTING OF DRAGON FRUIT (Hylocereus undatus) STEM CUTTINGS

A pot experiment was conducted on the rooftop garden of Department of Horticulture, Sher-e-Bangla Agricultural University during August 2015 to October 2015 to evaluate the performance of different Indol Butyric Acid concentrations on rooting of Dragon fruit stem cuttings. IBA concentration viz. T_C= Control, T₅₀= 50ppm, T₇₅= 75ppm, T₁₀₀= 100ppm were used as treatments in this experiment under Completely Randomized Design with 3 replication. Increasing IBA concentration gave better results in all the studied parameters with the highest root number (13.2), root length (12.7cm), root diameter (1.5mm), fresh weight (2.7g) and dry weight (0.8g) found in T₁₀₀ and the lowest of all these were found in TC (6.3, 5.7cm, 0.9mm, 0.3g, 0.2g respectively). So, the result suggests that treating Dragon fruit stem cuttings with 100ppm of IBA solution is best for successful establishment.
