Abstract
This aim of this research is to determine the effect of Indole Butyric Acid (IBA) concentration to the origin of the planting material and their interaction on the growth and development of Millie Dillard-2 (MD2) variety pineapple seedlings so that quality pineapple seedlings with good performance and rooting are obtained. The research was conducted from May to December 2023, experimentally using a factorial Randomized Block Design (RBD). The first factor is IBA concentration of 0 ppm, 200 ppm, 400 ppm, and 600 ppm. The second factor is the origin of the crown shoots and sapling shoots. Thus, there were eight treatment combinations; each treatment was repeated three times, so there were 24 experimental units. Each experimental unit used 3 plant samples. The Analysis of Variance (ANOVA) results were tested further using the Duncan’s Multiple Range Test (DNMRT) test at the 5% level. Observation were carried out on seedlings aged 30 Day After Planting (DAP) and 100 DAP with observation variables consisting of the root fresh weight aged 30 DAP and 100 DAP, total primary roots and increase in number of leaves. The research results show that giving a concentration of IBA of 400 ppm and seedling shoot planting material is the best treatment combination to be applied to MD2 pineapple seedlings.
