Oilseed flax is not commonly grown in Belgium, despite its various advantages and its increasing demand. From an agronomic perspective, it is an interesting plant to insert in the crop rotation and it is relatively easy to grow. From a nutritional point of view, it is rich in omega-3 fatty acids, essential amino acids, dietary fibers and antioxidants such as lignans. This makes flaxseed a functional food, that is a foodstuff that prevents many chronic diseases and provides numerous health benefits. More documentation regarding agronomical practices of flax cultivation and their effects on yield as well as on the nutritional profile of the seeds is needed. The nitrogen input is believed to be an important driver determining yield and quality parameters such as oil yield, fatty acid profile, vitamin E and protein contents of flaxseed. As more and more farmers move to reduced-tillage practices, it would be interesting to determine the effect of such practices on flax yield and quality. The aim of this master’s thesis was therefore to determine the effect of nitrogen fertilization level and tillage practice on the yield of flaxseed, but also on its nutritional profile. To this end, flax was grown in a field in Vieux-Sart (Belgium) with six different levels of nitrogen and either under tillage or no-tillage conditions. After harvest, seeds were analyzed to determine oil yield, fatty acid profile, vitamin E profile and protein content. Many results were not significant, which can be partly attributed to the exceptionally dry and hot climatic conditions of spring and summer 20
