The objective of the experiment was to determine the effect of two levels of mineral fertilization (90 and 180 kg NPK/ha) and three sowing rates (300, 600 and 900 germinating seeds per 1 m2) on chemical composition of two linseed cultivars (Opal and Hungarian Gold) differing in seed colour. Basic chemical composition, fatty acid profile, amino acid composition and yields of the seeds were determined. The yields of protein and fat were also estimated. Seeds of these two studied cultivars did not s how any significant differences in chemical composition after the application of different agro-technologies. Regardless of the cultivation factors, cv. Opal had higher NDF and ADF contents and over twice higher content of ADL (40.3 vs. 19.9 g/kg DM; P<0.05). Increased mineral fertilization caused an increase in the content of amino acids, especially glutamine, arginine and asparagine, in seeds. Fatty acid profile in seed oil did not show significant changes as a result of the cultivation factors applied.
