Growth and development of pigeon pea (Cajanus cajan) on the differences of Fitosan concentration

Pigeon pea is Leguminoceae plant that survives in drought conditions and able to grow in various soil types. Pigeon pea is potentially used for soy substitution, but has not been intensively cultivated in Indonesia. Fitosan is result of chitosan irradiation. This research was conducted to determine the effect of soaking pigeon pea seeds in various Fitosan concentrations. The research was designed as Randomized Complete Block Design factorial with two factors. The first factor was Fitosan concentration, namely control (without Fitosan), 2 ml l(-1), 4 ml l(-1), and 6 ml l(-1). The second factor was color of pigeon pea namely black, white, and brown. The results showed that best Fitosan concentration was 2 ml l(-1) which accelerate shoots appear and increase plant height up to 4 weeks after planting. The fastest flowered was in black pigeon pea that soaked with Fitosan 2 ml l(-1) and yields the most pods, white pigeon pea flowers appear fastest in soaking with 6 ml l(-1), while the brown pigeon pea has not flowered and produces pods until the end of the observation. There is no interaction between Fitosan concentration and the differences of color pigeon pea seeds on the growth and development plants.
