Linseed (Linum usitatissimum) oil is used as anti eczema; it is
moisturizing and anti - intlammatory. The oil contains F vitamin, and is used as laxitive. The main aim of this investigation was to find out the effects of some
variables factors such as N - fertilizer and water supply on growth, seed yield and active substances (fatty oil and fatty acids) of linseed. In this study Linum
usitatissimum, Olajozon cultivar seed provided from Hungary was used. The
statistical design was a splIt-plot arrangement of a randomized complete block
design with four replicates in each treatment. The irrigaUon factor was
considered as the main plot (0, 20 and 60 mm) and N-fertilizer applications (0. 50, 150 and 250 kg/ha) were allocated to subplots. The results indicate that
increasing N - fertilizer to ISO kg/ha significantly increases plant hight, number of branches, number of fruits as well as seed yield. but had no significant effect
on 1 non seed weight. According to the results. a suitable amount of fatty acids
was produced from plants in control plots (without N - fertilier and irrigation).
Supply of water (60mm) increased plant hight, number of branches, number of fruit and seed yield, but had no effect on seed oil content.
