The effect of AB mix and organic fertilizer concentration on growth and yield of two mustard varieties in a floating hydroponic system

Abstract The Efforts to increase mustard production can be carried out by developing cultivation technics using a Floating Hydroponic System (FHS) with additional nutrients support plant growth. This study aims determine the best combination of AB Mix and organic fertilizer nutrient concentrations for growth yield two types varieties FHS hydroponics. used was POC NASA, which contains sufficient macro micronutrients production. conducted at Greenhouse in Faculty Agriculture, Universitas Syiah Kuala from December 2021 February 2022. design 4x2 Split Plot Design 3 replications. Main plots (Tosaka Nauli F1 varieties) sub-plots (5 ml/L Mix+2 7 9 11 Mix+ 2 NASA). results showed that found + NASA Tosaka variety. There is an interaction between treatment significantly affect fresh weight per plant. yields were concentration on
