Effects of Fertilization on the Fatty Acid Content of Oil Flax

The paper presents the results of a two-year experimental research of two varieties of flax oil and population in two locations (Ćojluk and Ostrožnica, Bosnia and Herzegovina), with the aim of determining the variability of seed yield, oil content and fatty acids composition in oil. The experiment was set in field conditions by using random block schedule with four repetitions. The common technology of flax cultivation is applied, without chemicals, but with different treatments of fertilization: T1 control, T2 fertilizer, T3 organic fertilizer, T4 bacterial fertilizer and T5 organic + bacterial fertilizer. Two varieties of flax were used for the research: Mikael, Biltstar and population Vrtoče. We determined statistically significant differences in seed yield, oil content, and fatty acid composition, in relation to year of research, location and fertilization treatments. The presence of five most significant fatty acids was processed, C16:0, C18:0, C18:1, C18:2 and C18:3, and whose content and interaction in the seed significantly depend on fertilization treatments.
