Water spinach is a heavy metal accumulator plant if grown in polluted soils. This raises the concern of water spinach safety as one of the most consumed vegetables in Asian household. Land pollution in water spinach cultivation area can be caused by industrial activities that involve heavy metals such as tannery. Industrial waste such as chrome leaches to the water system that eventually will be used as irrigation source for agriculture. Organic fertilizer is a potential solution to increase water spinach growth, yield, and absorb heavy metal contaminants. This research evaluated the effect of type and dosage of organic fertilizer on water spinach that grown in chromium-polluted soils. This research design used Randomized Block Design (RBD) with nine treatments and three replication. The treatment of combination of types and dosages of organic fertilizer. There were dried leaves, goat manure, and vermicompost with dosage of 5 t ha-1, 10 t ha-1 and 15 t ha-1. The results of this research showed that the effect of combination of organic fertilizer type and dosages at chrome polluted media gave better effect on growth, and yield of water spinach. Giving vermicompost of 15 t ha-1 gaves better effect on plant height, fresh weight of plant, and dry weight of plant, meanwhile the doses of 5 t ha-1dried leaves showed the lowest chrome content compared to other treatments, but these plants are still unsafe for consumption due to high chrome content.Keywords: water spinach, organic fertilizer, chromium, yield
