Abstract

Vegetative propagation through grafting is an important method for producing high-quality Siger avocado (*Persea americana*) seedlings. This study aimed to determine the effects of rootstock covering and rootstock age on the success of Siger avocado grafting. The study was conducted in Denggungan Village, Banyudono, Boyolali, using a factorial Completely Randomized Design with two factors and five replications. The first factor was rootstock covering (A₁: covered; A₂: uncovered), while the second was rootstock age (B₁: 4 weeks, B₂: 5 weeks, and B₃: 6 weeks). Data were analyzed using ANOVA followed by Duncan’s Multiple Range Test at 5%. Rootstock covering significantly increased seedling height, post-grafting plant height, leaf number, and leaf width. Four-week-old rootstocks produced the highest post-grafting plant height (26.70 cm) and leaf number (15.24 leaves). No significant interaction was found between covering and rootstock age for all observed parameters. The combination of covering and 4-week-old rootstocks (A₁B₁) showed the best vegetative performance and is recommended for efficient Siger avocado seedling production.
