ARTICLE INFO                                            ABSTRACT

Plant onion (Allium cepa var. ascalonicum) is one of the vegetables that are very well known by the public as a flavoring condiment cuisine. To increase the production of onion then the very need for fertilization fertilizer organic, among others. Organic fertilizer has a role in providing the nutrients needed by plants. The use of organic fertilizer is an of the efforts to improve soil fertility, because organic fertilizers is porous, raising the ability of the soil in the hold (tie) water. The application of organic fertilizer in the system cultivation can increase the content of organic matter or C-organic and N content of total land. The purpose of this research is to know the type and dosage of organic fertilizer and their interaction towards growth and crop yield of onion. Experimental design was a randomized Complete Design Group (RAK) consists of two factors and arranged in Factorial, i.e. the first factor is the type of fertilizer treatment consisting of organic: PKS: Cow Manure, PKK2: Goat Manure, PKA: Chicken Manure and the second Factor is the dosage of organic fertilizer, which consists of: DPO0:0 t ha-1 (0 kg swath-1), 10: DPO1 t ha-1 (1.20 kg swath-1): 20 DPO2, t ha-1 (2.40 kg swath-1), DPO3:30 t ha-1 (3.60 kg ha-1). Observation of the growth component, measurement results, results as well as supporting multiple variables. The collected data were analyzed with the analysis Variant (ANOVA) according to the experimental design was used. If there is a real interaction influence against the observed variable is then continued with a different test studies on average use the test double distance Duncan (DMRT) on levels 5% and if only a single factor in a real influence, then proceed with the average difference test with test BNT on levels 5%. Based on research results that different types of manure, not influence against growth and crop yield of onion while given doses of manure increases would boost growth and crop yield of onion Red on the treatment dose of chicken manure with a dose of 30 t ha-1 (3.60 kg/compartments). Not found the interactions between types and doses of manure towards growth and crop yield of onion. It is because this type of fertilizer have not given the decomposition of perfect so that interaction has not occurred.
