Abstract:
An experiment was conducted at Fruit Science Nursery, College of Horticulture and Forestry, Pasighat, during 2022 to know the influence of IBA (Indole 3-butyric acid) concentrations, types of stem cutting and months on rooting responses of Dragon fruit (Hylocereus costaricensis) under the foothills of Arunachal Pradesh. The result of one year long experiment revealed that after 90 days of planting, percentage of rooting (98.9 %) was observed highest in 7000 ppm IBA with cutting exposing interior wood portion during June, longest root length (29.60 cm) with 7000 ppm IBA applied to slanting cut during May, maximum number of primary roots per cuttings (11.30), maximum fresh weight (1.78 g) and maximum dry weight of roots (0.47 g) were observed with 5000 ppm IBA with cutting exposing interior wood portion during June. Therefore, considering the performance of all the factors in all the parameters recorded, 5000 ppm IBA with cutting exposing interior wood portion during June showed the best performance and is recommended for the propagation of dragon fruit.
