The development of suitable plant growing media is essential to address sustainability concerns in horticultural plant production. Currently, unconventional growing media components with unique physico-chemical properties are being used, but their effects on microbial activity vital for plant growth and development are not well understood. This study was conducted at the horticultural experimental area of Khalsa College, Amritsar, during the 2022-2023. A randomized block design with three replications was employed, with each replication consisting of nine treatments, including soil, sand, vermicompost, cocopeat, sawdust, and their combinations. The study aimed to investigate the impact of different growing media on the rooting, success, and survival of dragon fruit cuttings. Morphological parameters, such as sprouting, plant height, shoot and root length, as well as the fresh and dry weight of shoots and roots, were measured. The results revealed that the combination of soil and vermicompost (1:1) was the most effective in promoting sprouting, plantheight, shoot and root length, diameter, and the fresh and dry weight of both shoots and roots, while also enhancing primary and secondary root formation. The study concludes that the combination of soil and vermicompost (1:1) provides the optimal growing media for dragon fruit cuttings, fostering improved growth and root development. This media mix not only supports better morphological growth but also enhances overall plant health, suggesting its potential for sustainable horticultural practices.
