The Influence of Consortia of Beneficial Microorganisms on the Growth and Yield of Aquaponically Grown Romaine Lettuce

This study evaluated the effects of fish farm wastewater from production hybrid sturgeon (Acipenser gueldenstaedtii Brandt × Acipenser baeri Brandt) on growth and quality parameters romaine lettuce (Lactuca sativa var. longifolium cv. “Elizium”). The tested combinations were wastewater, enriched with one three microbiological consortia, supplemented minerals. best plants obtained in combination farming mineral nutrients. application beneficial consortia positively influenced fresh weight leaves number per plant. However, fed minerals characterized by strongest symptoms leaf tip-burn lowest commercial value. By comparison, only or microorganisms a high, similar After increased doses minerals, there was evidence greater activity involved nutrient cycling aquaponic cultivation. significantly numbers bacteria culture liquids 7, 14, 21 days after inoculation.
