Growth and Quality of Leaf and Romaine Lettuce Grown on a Vertical Farm in an Aquaponics System: Results of Farm Research

The integration of indoor vertical cultivation with a recirculating aquaculture system into an aquaponic has the potential to become one most effective sustainable production systems for fish and leafy vegetables. In this study, lettuce was produced on rafts in coupled recirculation plant factory under controlled environmental conditions. aims study were evaluate yield, mineral status, health-promoting bioactive compounds leaf romaine cultivars grown system. yield biometric parameters quality leaves (nitrate, mineral, L-ascorbic acid, carotenoid, phenolic compound, total polyphenolic contents) examined. Monitoring water showed low concentration nitrates, phosphorus (P), potassium (K), magnesium (Mg), but proportion nutrients as well pH stable throughout period. heads ‘Yakina’, ‘Pivotal’, ‘Waygo’ reached fresh weight 86 g, average, 23% higher than ‘Nordice’ over three-week Despite nutrient solution, status lettuces ‘Yakina’ ‘Pivotal’ within optimal range. concentrations chlorophyll carotenoids those ‘Waygo’. nitrate, phosphorus, contents below range; however, their polyphenol highest. Our results indicate that effectiveness terms biomass nutritional value depends genotype.
