Provision of mangosteen seedlings (Garcinia mangostana L.) of high quality and rapid growth is a desire of the farmers, especially seedlings from seeds. But until now has not availabled, especially in Lampung, because the growth is slow due to minimal root system and low regeneration. The aim of this research was to get the technology of growth of mangosteen seedling through the use of benzyl-adenine (BA) and fertilizer application. The study was conducted at the Faculty of Agriculture greenhouse, from October 2016 to January 2017 that the treatment was arranged in a factorial (4x2) in a complete randomized block design. The first factor was concentration of BA: (0, 10, 20, 30) mg L-1 and second was the type of fertilizer: organic liquid fertilizer (POC) and NPK compound fertilizer. BA was applied at 4 weeks after transplanting by spraying at the tip of 3x (@ 10 ml plant-1) at 10-day intervals. The fertilizer was applied 2x @ 50 ml plant-1, the day before application of BA, by spraying it onto the planting media of each POC concentration of 12.5 mL L-1 and NPK of 5 g L-1. The results showed that the use of BA with increasing concentration can increase the number of leaves but lower the height of the plant when used NPK compound fertilizer, but if the use of POC (Biomax Grow) fertilizer, BA does not show any effect. In the observation of the number of secondary roots, the use of BA concentration of 20 mg L-1 treated with POC fertilizer, it was higher than that of NPK compound fertilizer, but at lower or higher doses, the two types of fertilizers showed no difference, while at root length primary, the higher the concentration of BA, the length was increasing. Keywords: Mangosteen, benzyl-adenine (BA), concentration, fertilization
