Due to the oil quality which conteins omega 3 and omega 9 fatty acids and the pleasant taste, flax oil, in addition to traditional uses, increasingly finds new uses in areas where until recently there were no data on the use of this culture. Among the new areas of use, areas where there is a growing demand for raw materials, we can specify: medicine, food industry (pastry and bakery), cosmetics. This paper presents the values ​​of seed production and physical indices (mass of 1000 grains and hectoliter weight) obtained in five varieties of flax oil approved in Romania, under the influence of some foliar fertilization products and different densities, in order to determine whether these values ​​depend on applied products and the influence on production quality. The biological material used consists of linseed varieties Lirina, Alexin, Floriana, Florinda and Iunia 96 sown at different densities of 600 germinable seeds/m², 800 germinable seeds/m² and 1000 germinable seeds/m². Fertilization was performed on following agrofunds: N 0 P 0 , N 64 P 48 , N 96 P 64 , N 64 P 48 + foliar fertilizer combination Fertileader Viti + Corona K, N 96 P 64 + foliar fertilizer combination Fertileader Magical + Corona K. The best yields were obtained from Florinda variety fertilized with N 96 P 64 + foliar fertilizer combination Fertileader Magical + Corona K , 800 germinable seeds/m² seeding density, density that ensures adequate nutritional space for flax oil plants. Good results were also obtained at the other varieties, where official production values ​​were exceeded. Regarding the analyzed physical indices, mass of 1000 grains and hectoliter weight, no major deviations were observed from the official descriptions of studied linseed varieties. The only differences occurred regarding the mass of 1000 grains at two varieties (Iunia 96 and Alexin) where the index registered a slight increase. The results obtained by Mr. I. Neştian during the experiments conducted to develop the PhD thesis with the title “Research on the influence of some ecological, biological and technological factors on production and seed quality of linseed (Linum usitatissimum L.), in order to diversify areas of use”, once again reinforce the results from the literature according to which, fertilization, as input to the culture of flax oil, is fully justified economic. The author concluded that, regardless of environmental conditions during the three years of experiment, mineral fertilization always produced very significant increases in production (Neştian I., 2007).
