Application of Lamtoro Leaf Liquid Organic Fertilizer on the Growth and Production of Red Lettuce

Abstract

Lettuce is a type of vegetable that is very popular in Indonesia. Efforts to increase lettuce production can be made by providing liquid organic fertilizer. The study aimed to determine the application several of liquid organic fertilizer concentrations of lamtoro leaves on the growth and production of red lettuce. The research was carried out from February to May 2021, in the Japos Housing area, Pondok Aren, South Tangerang City. The research used a Randomized Completely Block Design (RCBD), with five liquid organic fertilizer (LOF) concentrations, namely P0: Inorganic fertilizer (Control), P1: 5% LOF concentration, P2: 10% LOF concentration, P3: 15% LOF concentration, and P4: 20% LOF concentration. The effect of inorganic fertilizers is more visible on several parameters, such as plant height, number of leaves, and root weight. Lamtoro leaf liquid organic fertilizer treatment, especially at a concentration of 10%, can provide results equivalent to inorganic fertilizer on several growth parameters of red lettuce plants, wet weight parameters, and plant consumption weight. In general, crop yields are still low, thought to be influenced by factors such as soil type, climate, and plant genetic variations which influence the. plant's response to the fertilizer provided.
