Efficacy of various growing substrates on root development in cuttings of dragon fruit (Hylocereus undatus L.)

Abstract

In this study conducted at Horticultural Research Farm No. 1, Babasaheb Bhimrao Ambedkar University, the impact of various growing media on the root and shoot growth of Hylocereus undatus L. (dragon fruit) cuttings was investigated. Different compositions, including pure and ratios of 1:1 and 2:1:1 (v/v), were employed in the media. The experiment encompassed nine treatments and followed a Randomised Block Design replicated three times. The most favorable root parameters such as the average number of roots (10.20), root thickness (0.32 mm), root volume (2.98 cc), and root fresh and dry weight (3.21 and 0.98 g, respectively)—were observed when utilizing a mixture of Soil + Sand + Vermicompost (in a 2:1:1 ratio). Notably, the initiation of roots occurred in the shortest duration (25 days) within the soil + sand + vermicompost (2:1:1) group. Additionally, this particular media combination demonstrated the longest average root length, measuring 25.05 cm.
