Study of ABMix nutrition concentration and water concentration in hydroponics with Deep Film Technique (DFT) system in Central Sulawesi

Abstract

Hydroponic cultivation is an alternative to utilize narrow land or land that is not suitable for agriculture. An important role in hydroponic cultivation is nutrition, where nutrients are dissolved in water before being flowed into the hydroponic device. The provision of different types of nutrient solutions and different water concentrations greatly affects hydroponic plants' productivity. This research was conducted from September to November 2019 at the Sidondo Agricultural Technology Research and Study Installation (IP2TP). This study aimed to determine the concentration of raw water and AB Mix solution concentration, which is good for plant growth in hydroponics. The study used a factorial randomized block design (FRBD) consisting of two factors and three replications. The treatments were combination factor of AB mix concentration as total dissolved solids in ppm and kind of AB Mix product. The AB Mix concentration consists of 20 ppm and 200 ppm. Then AB Mix product consist of Agromax and HidroJ. The result showed that concentration 20 ppm of Agromax nutrient solution give the best result for all parameter (plant height, number of leaves, stem diameter, leaf area, root length, and weight of root, leaf and stem)
