ABSTRACT
One of the critical success cocoa cultivation was used of quality plant materials. Cocoa plant
material obtained through propagation techniques Somatic Embryogenesis (SE) was the latest
method that can produce planlet that are the same with parents, have a taproot and a branched
structure similar with plant from seeds. Another advantage of this SE technique can be massproduced
seedlings, pest-disease free, growth is more uniform, more vigor, high yield and
drought resistant. The objective of the experiment was to know the growth media composition
which gave the best effect on growth cacao seedling (Theobroma cacao L.) from Somatic
Embryogenesis (SE). The experiment was conducted at The Agricultural Experiment Station of
Agriculture Faculty, Padjadjaran University, Jatinangor, altitude ±700 m above sea level with
soil type is Inceptisols. The experiment was conducted from June until October 2013, used
Randomized Block Design (RBD), consisted of nine treatments combinations and replicated
three times. The treatments were topsoil : casting (2 : 1) + urea 0,5 g application-1, topsoil :
cattle dung (2 : 1) + urea 0,5 g application-1, topsoil : cacao pods compost (2 : 1) + urea 0,5 g
application-1, topsoil : casting (2 : 1) + urea 0,75 g application-1, topsoil : cattle dung (2 : 1) +
urea 0,75 g application-1, topsoil : cacao pods compost (2 : 1) + urea 0,75 g application-1,
topsoil : casting (2 : 1) + urea 1 g application-1, topsoil : cattle dung (2 : 1) + urea 1 g
application-1, topsoil : cacao pods compost (2 : 1) + urea 1 g application-1. The result of the
experiment showed that the growth media composition consist of topsoil : casting (2 : 1) + urea
0,75 g application-1 gave better effect on vegetative growth of cacao seedling from SE compared
to other treatment combinations, increased stem diameter, leaves number, shoot dry weight and
total plant dry weight at 16 WAP is 17,54 g.
