Market demand for leaf onion has increased from year to year but the growth and production of leaf onion has not increased because the farmers always fertilize using chemical fertilizers. This study aims to determine the effect of seaweed liquid organic fertilizer on the growth and production of leaf onions.

The treatment carried out were without giving of seaweed liquid organic fertilizer on the leaves onion plant (P0), giving seaweed liquid organic fertilizer to the leaves onion plant with a concentration of 5 ml / liter (P1), 10 ml / liter (P2), 15 ml / liter (P3), and 20 ml / liter (P4). The parameters observed were plant height growth, growth in number of leaves and weight of harvesting leaf onion. Observation data were analyzed using analysis of variance level 5% and Duncan's advanced test at 5% level. The results showed that the application of seaweed liquid organic fertilizer had a significant effect on the growth of leaf onion plants and the production of onion leaf.
