Promoting the growth of soybean can be achieved by organic fertilization. The aim of the research is to determine the effect of the types and doses of organic fertilizers on soybean growth. The four month study was conducted at Manokwari Regency, West Papua, Indonesia. The treatments were laid out in a factorial randomized block design (RBD) in which the first factor is the types of organic fertilizer consisting of husk ash (F1), compost (F2), chicken manure (F3) and goat manure (F4), while the second factor is the organic fertilizer doses comprising of zero fertilizer rate (D0) and 5 tons/ha fertilizer rate (D1). The results showed that goat manure (F4) achieved the highest, while the type of fertilizer scored the lowest is compost (F2). Fertilizer doses were significantly different in all growth parameters, namely D1 (5 tons/ha) compared to D0 (without fertilizer). The interactions were insignificant statistically different in all growth parameters, when goat manure (F4D1) tended to record the highest and no application of compost fertilizer scored the lowest.
