Effect of AB Mix and Bokashi Fertilizer on the Growth of Mustard Green Plant (Brassica Juncea L. Var. Tosakan) with Deep Flow Technique (DFT) Hydroponic System

Abstract

Hydroponic planting provides opportunities for anyone and anywhere for people to grow plants. This study uses the Deep Flow Technique (DFT) hydroponic where water and nutrients are circulated. This research determines the effect of various types of fertilizer and their concentration level on the growth of the Mustard Green plant, particularly on the number and weight of leaves. Fertilizers fermented are Cauliflower leaves bokashi fertilizer, cow dung bokashi fertilizer, and a mixture of both with Effective Microorganisms 4 (EM4), and Hydroponic cultivation of leafy vegetables commonly used hydroponic nutrient solution in the form of a standard solution (AB mix). The concentrations of fertilizer are 400, 600, 800, 1000, and 1200 ppm. Two analytical data were used, the Friedman test for the variety of concentrations and One-way ANOVA for the effect of the fertilizer. The results show that the concentration variations of AB Mix and mixed bokashi fertilizer give significant differences in the growth, and in the number of leaves, and all concentration variations show significant differences. The results also show that the types of fertilizer influences significantly the growth of the Mustard Green plant based on the number and weight of leaves.
