Abstract

Jasminum subtriplinerve Blume is a high-value medicinal plant widely distributed in central Vietnam, known for its important bioactive compounds and traditional uses in herbal medicine and health-enhancing products, particularly beneficial for postpartum women. Despite its increasing economic importance, current cultivation practices remain largely traditional, resulting in low yields and unstable quality. The objectives of this study are to determine optimal planting density and trellis construction methods for J. subtriplinerve under field conditions. Two experiments were conducted in Jan to June 2025 using a randomised complete block design with three replications. The first experiment evaluated three different planting densities (20 × 20 cm, 30 × 30 cm, and 50 × 50 cm) without trellises, while the second experiment combined these densities with an A-frame trellis system (1.2 m high, 1.0 m wide at the base). Growth parameters and yield were recorded periodically. Results showed that planting density had no significant effect on plant height and leaf number but influenced the number of first-level branches and yield. The application of trellis significantly enhanced plant growth, particularly plant height and the number of primary branches. After six months, fresh yield ranged from 30.8 to 34.1 t/ha in trellised and from 28.5 to 33.1 t/ha without trellis systems. The highest yield was obtained at a planting density of 30 × 50 cm (approximately 111,000 plants ha⁻¹) combined with trellis. These findings provide a scientific basis for applying improved cultivation practices and supporting the sustainable production of J. subtriplinerve in Central Vietnam.
