Abstract:
Plant propagation is important factors in plant production. Many problems have been arisen in
dragon fruit propagation, such as the rooting inability and the yellowing of cuttings. To solve this
problem, the understanding how to choose suitable growing media and chemical control is
needed. This study was conducted to investigate the effects of different growing media
compositions on using shrimp paste, vermicompost and vitamin-B1+amino acid for promoting
root growth of dragon fruit cutting was studied at Faculty of Agricultural Technology Songkhla
Rajabhat University, Muang Songkhla, Songkhla province, southern Thailand from February to
June, 2019. The experimental design was CRD growing media compositions with eight
treatments and sampling for five replications namely T1 (shrimp paste soaking + coco peat), T2
(shrimp paste soaking + soil-based mix), T3 (vitamin-B1+amino acid + coco peat), T4 (vitaminB1+amino acid + soil-based mix), T5 (vermicompost + coco peat), T6 (vermicompost + soilbased mix), T7 (coco peat) and T8 (soil-based mix). The study revealed that vermicompost,
vitamin-B1+amino acid and shrimp paste treated stem cuttings gave better growth root system.
Cuttings treated with vermicompost + coco peat produced the best results in number of root,
number of shoots and the lengths of the roots. Thus, it was concluded that vermicompost was
better growing media than other medias for propagating dragon fruit by cuttings. |
