Agrobiological study of lettuce hybrids (Lactuca Sativa L.) in hydroponic culture

Abstract

The aim of this research was to evaluate the agrobiological performance of several lettuce hybrids grown in a hydroponic system Nutrient Film Technique (NFT). The study included six lettuce hybrids known for their high potential in hydroponic cultivation, all from the Rijk Zwaan breeding portfolio. Barlach is a red-leaf Butterhead type, Sungari is a red-leaf Crystal type, Dunand is a dark green Crystal type, Rictus is a dark green Romaine type, and Exact is a Frisée type with deeply incised and curled light green leaves. The research was conducted in the hydroponic greenhouse of the GreenBioHub complex, within the experimental sector of the Faculty of Agricultural, Forestry and Environmental Sciences. The NFT system used was a recirculating Nutrient Film Technique setup, which includes slightly inclined gullies through which a thin film of nutrient solution continuously flows.
