【 摘 要 】

Kemiri sunan [Reutealis trisperma (Blanco) Airy Shaw] is a vegetable-oil producing plant with great potential to be developed as biodiesel feedstock. However, to develop Kemiri Sunan on marginal land, there is a necessity to innovate the cultivation including by applying fertilization or providing nutrients with plant supplements such as chitosan. This study used a Randomized Complete Block Design consisting of 2 factors. The first factor was the concentration of chitosan per plant: 10, 20, 30 and 40 ml/l. The second factor was the frequency of chitosan application: 3-, 4- and 5-time provision. The controlling variable was without chitosan application. The data were analyzed for the diversity and continued with Duncan Multiple Range Test at the level of 5%. The concentration of 20 and 30 ml/l chitosan and the frequency of 4-time chitosan resulted a better effect than other treatments. The vegetative growth of plants with chitosan administration was shown to have a better growth response than those without chitosan (control).
