Rooting ability in Moabi was examined using 972 single-node leafy stem cuttings set in each of three blocks of a split-split plot experimental design in nonmist propagators. Each main plot contained three rooting media (sand, sawdust, and a 50:50 mixture of sand and sawdust), whereas three auxin types (indole-3-acetic acid [IAA], indole-3-butyric acid [IBA], and 1-naphthalene acetic acid [NAA]) and a control (alcohol) were testedat the subplot level. At the sub-subplot level, three leaf areas (25, 50, and 75 cm2) were investigated. Significant(P0.05) and nonsignificant substrate hormone leaf area interactions on rooting percentage were foundat week 8 and during the rest of experiment, respectively. Significant sand versus sawdust IBA versus IAAand NAA quadratic components of leaf area interaction on rooting percentage was identified from week 10to week 14 (P0.0462–0.038), and the highest rooting percentage (85.27.24%) was found in 75 cm2IBA sand-treated cuttings at week 14. Significant substrateleaf area interaction on rooting percentage was observed throughout the experiment. Interacting substrate leaf area significantly influenced the number of roots per rooted cutting at week 22. This study indicated that Moabi is amenable to vegetative propagation within14 weeks.
