This study evaluated combinations of liquid organic fertiliser (LOF) and NPK 16:16:16 fertiliser for improving the growth and yield of bawang dayak (Eleutherine palmifolia (L.) Merr.) under lowland conditions in Bengkulu, Indonesia. The experiment was conducted from October 2025 to January 2026 using a completely randomised design with seven fertiliser treatments and four replicates, resulting in 28 experimental units. The treatments comprised 2.50 g NPK per plant; 2.50 g NPK per plant combined with either 1% or 2% LOF; 1.25 g NPK per plant combined with either 1% or 2% LOF; and 1% or 2% LOF applied alone. Plant height, number of leaves, and number of tillers were recorded during growth, while bulb and root characteristics were measured at harvest. Analysis of variance showed that the fertiliser treatments significantly affected only the number of tillers. Treatment P4, consisting of 1.25 g NPK per plant and 2% LOF, produced the lowest number of tillers and differed significantly from the other treatments. No significant treatment effects were detected for plant height, number of leaves, fresh bulb weight, fresh bulb weight per clump, number of bulbs per clump, bulb diameter, fresh root weight per clump, or root length. Treatment P3, comprising 1.25 g NPK per plant and 1% LOF, appeared relatively efficient in supporting growth and yield, although it did not significantly improve the measured yield variables.

This study aimed to determine the effects of different concentrations of Catharanthus roseus leaf extract on the morphological characteristics of Dendrobium orchids. The research was conducted in the greenhouse of the Agronomy Laboratory, Faculty of Agriculture, University of Bengkulu. The experiment was arranged in a completely randomised block design (CRBD) consisting of seven concentrations of C. roseus leaf extract: 0%, 0.05%, 0.1%, 0.15%, 0.2%, 0.25%, and 0.3%. Dendrobium orchid seedlings ready for acclimatisation were soaked in the extract solution for 15 minutes before planting. The observed parameters included plant height, plant diameter, number of leaves, leaf length, leaf width, number of roots, and stomatal density. Data were analysed using analysis of variance (ANOVA), followed by the least significant difference (LSD) test at the 5% significance level. The results showed that C. roseus leaf extract significantly affected stomatal density but had no significant effect on plant height, plant diameter, number of leaves, leaf length, leaf width, or number of roots. Compared with the control (46.12 stomata mm⁻²), the extract reduced stomatal density, with the lowest value recorded for the 0.05% treatment (33.02 stomata mm⁻²). Overall, the application of C. roseus leaf extract reduced stomatal density in Dendrobium orchids during the acclimatisation phase.
