The experiment took place at the University Farm Green House, Cikabayan. The study lasted from February to August 2011. This study used a randomized design Completly Group with two factors with the first factor is the concentration of chitosan consisted of three levels of 0, 10 and 20 ppm/ plant. The second factor is the concentration of guano fertilizer with 3 levels of 0, 10 and 20 ml / l water. Observations performed every single week for 5 months. The result showed that treatment with 10 ppm chitosan gave is significantly increased the number of pseudobulb (1.4). Guano 10 ml/l increased plant height at 10-19 Weeks After Treatment (WAT) (23.64 cm average an 19 WAT). At 9 Weeks After Treatment (WAT), leaf length at 9 Weeks After Treatment.
