Aquaponics is one of the recirculating aquaculture systems in which plant grows without soil. Considering the lack of information about aquaponic culture for main crops like pepper and the absence of comparison of plant conditions in soilless culture, in this experiment eco-physiological characteristics of pepper in hydroponics and aquaponics were investigated. After starting the plants to flow...
