Onion skin waste can be used as a mixed fertilizer that can accelerate plant growth because it contains compounds and substances that provide fertility. In addition to liquid fertilizer, there is manure that can be used in the process of plant growth to replace inorganic fertilizers. This study aims to determine the comparison of the effectiveness between shallot skin fertilizer and manure on leek plants. Onion (Allium fistulosum L.) is a vegetable commodity that has high economic value. The research method used is experimentation which is a method in quantitative research by examining cause and effect and comparing the results of each component.
