Abstract

Corn is the main food crop after rice. It is also an ingredient for livestock feed. The availability of corn needs to be supported by the availability of sufficient fertilizer during plant growth, including liquid organic fertilizer. The high price of liquid organic fertilizer is one of the obstacles in the use of this fertilizer. Therefore a cheaper source of liquid fertilizer is needed. This study investigates the best effect and dose of the use of POC from landfill leachate on the growth and yield of corn. The research method is an experimental method using a Completely Randomized Design (CRD) consisting of six treatments and four replications using polybags. The treatments: A = 60 ml leachate + biochar (without microorganism); B = 20 ml POC/L water; C = 30 ml POC/L water; D = 40 ml POC/L water; E = 50 ml POC/L water; and F = 60 ml POC/L water. The results showed that POC awarding significantly affected leaf area (cm2), and cob weight (g) but not significantly different from plant height (cm) and stem diameter (cm). The dose of 40 ml of POC/L water is the best treatment of the use of POC from landfill leachate on the growth and yield of corn plants.
