Artichokes (Cynara cardunculus L.) contain many minerals, vitamins, fibres, polyphenols, flavones, inulin, flavonoids. Traditionally artichoke is used as food and medicine. Experiments were carried out to clarify the effect of a type of soil on the yield and quality of artichoke head. Experiments were arranged in two different soils: brown soil with residual carbonates (BRk) and the soil strongly altered by cultivation (ANt) of the Pure Horticultural Research Centre during vegetation season of 2014. Artichoke ‘Green Globe’ seeds were subjected to vernalization before sowing. Artichokes were grown in 4 replicas with planting scheme 70 × 90 cm. First artichoke heads were harvested on 28 July in BRk soil. The yield and its quality were analyzed during all vegetation period. Biochemical analyses were performed at the Latvia University of Agriculture, Institute of Soil and Plant Science. The results showed the tendency that the higher yield of artichoke heads was obtained in ANt soil, but the content of ascorbic acid, chlorophylls and phenols was higher in heads grown in BRk soil.
