Abstract:
Hydroponic Nutrient Film Technique (NFT) is one of the innovations in crop cultivation that can
increase the production both quantitively and qualitatively. The use of inorganic element in
nutrient solutions could not be eliminated, because it is the only source of nutrients for plants.
The addition of biofertilizer, especially endophytic bacteria is expected to reduce the use of
inorganic element to sustainable agriculture. The objective of study was to determine the best
combination of inorganic and biofertilizers that could increase the yield of pak choi plant in NFT
hydroponics. This study has been conducted at the Soil Biology Laboratory of the Agriculture
Faculty, Universitas Padjadjaran. Design of study used a Randomized Block Design (RBD) and
four replications with six treatments combination of ammonium nitrate Inorganic Fertilizer (IF)
and Biofertilizer (BF), that are 57,1% IF + 42,9% BF; 28,6% IF + 71,4% BF; and 14,3% IF +
85,7% BF along with one control treatment that is 100% IF. The result of this study indicates
that treatment of 14,3% IF + 85,7% BF could be used as the best recommendation in the
formulation NFT hydroponic nutrient solutions because it could increase the yield of pak choi
plants |
