Abstract
This research is motivated by the importance of the coffee plant specifically Robusta coffee (Coffea canephora) as an economically valuable plantation crop. One approach to obtaining high-quality planting material is through vegetative propagation using the cutting method. The success of these cuttings depends on the condition of the cutting material and the application of plant growth regulators. In this study, the number of buds and the concentration of IBA (indole-3-butyric acid) were manipulated to assess the growth response of coffee plant cuttings. The number of buds tested included 2, 3, and 4, while the IBA concentrations used were 0, 75, 100, 125, and 150 ppm. The objective of this research was to determine the effects of the number of buds, IBA concentration, and their interaction on the growth of Coffea canephora cuttings. The study employed a Completely Randomized Design (CRD) with a factorial arrangement of two factors: the number of buds (2, 3, and 4) and the IBA concentration (0, 75, 100, 125, and 150 ppm). This resulted in 15 treatment combinations, each replicated three times, for a total of 45 experimental units. Each experimental unit consisted of 3 plants. The parameters observed included the time to bud emergence, shoot length, number of shoots, number of leaves, root length, number of primary roots, root fresh weight, root volume, and shoot fresh weight. The data were analyzed using Analysis of Variance (ANOVA), and in cases where significant effects were found, the results were further evaluated using the Honestly Significant Difference (HSD) test at the 5% significance level. Based on the research results, the number of buds and the concentration of IBA elicited varying responses across several growth parameters in coffee plant cuttings. A combination of 4 buds and 100 ppm IBA yielded the highest mean values for several parameters, specifically shoot length, number of shoots, and fresh shoot weight. Conversely, the combination of these two factors did not show a significant effect on the observed rooting parameters. Thus, the data indicate that the most pronounced growth response occurred in the shoots, while root development did not show a significant response to the treatments. It is suggested that these findings serve as a reference for the propagation of coffee cuttings and that further research be conducted, incorporating a broader range of treatments or experimental conditions. .
