Abstract
Nutrient Film Technique (NFT) hydroponic systems is one of hydroponics types which utilizes water to supply the plant's nutrition needs and is circulated to plant's root through thin water. Hydroponic systems depends on inorganic fertilizer as nutrient solution. Utilization of biofertilizer is expected to reduce the inorganic fertilizer use applied in hydroponic systems. The aims of this experiment were to find the best dose combination of inorganic fertilizer and biofertilizer application toward chlorophyll content, pH, and number of pak choi's leaves in NFT hydroponic systems. This experiment was conducted in Soil Biology Laboratory Faculty of Agriculture Universitas Padjadjaran, from November 2018 until April 2019. Experiment was arranged in Randomized Block Design (RBD) consisting of four treatments combination of Nitrogen Fertilizer (NF) in ammonium nitrate solution (70 mg/2L) with 150 mL, 100 mL, 50 mL, and 25 mL doses combined with Bio-fertilizer (BF) with 0 mL, 75 mL, 125 mL, and 150 mL doses. The result showed that combination of inorganic fertilizer and bio-fertilizer could increase the number of pak choi's leaves, however it shows the same effect on the chlorophyll content and pH compared to other treatments. The combination of 25 mL ammonium nitrate fertilizer dose and 150 mL bio-fertilizer was able to reduce the recommended dosage of ammonium nitrate by 83.33%.
