Swiss chard (Beta vulgaris L., ssp. cicla) are grown for whole leaves or only for petiole. In Romania, chard is a less cultivated species, being present in some areas of Transylvania. Research aim was to establish how some Swiss chard cultivars behave, after fertilization with three different organic fertilizers. Plant growth, total production as well as dry matter, phenols, flavonoids, dietary fiber, carbohydrates and vitamin C content was measured. Experiment took place between 2021-2022, in an organic vegetable farm, in Săcueni, Bihor county, Romania. Three organic fertilizers were used: Lignohumate, Alcygol Z2M and Alg Green, applied 30 days after emergence, at the dose recommended by the manufacturer. Plant development, 60 days after emergence, was higher at Lucullus cultivar, fertilized with Alg Green, 54.35 cm. Production ranged from 44.67 t/ha (Carde Blanche d'Ampuis fertilized with Lignohumate) to 51.04 t/ha (Lucullus fertilized with Alg Green). Plant content in dry matter, fibers and vitamin C, was higher when plants were fertilized with Lignohumate. Phenols and flavonoids were higher at variants fertlized with Alg Green.
