\textbf{Abstract}
\begin{abstract}
\normalsize{
In order to study the effect of organic, chemical, biological and integrated nutrition systems on flax seed  (Linum usitatissimum L.) grain yield and quality, a field experiment was conducted at research field of Tarbiat Modares University on spring and summer 2013. Experiment was carried out as randomised complete blocks design with three replications. The treatments were consisted of control (no fertiliser), providing all nitrogen requirement from chemical source (urea), from biological source (nitroxin), from organic source (vermicompost), Integrative nutrition 1 (\mbox{50\,\%} urea+\mbox{50\,\%} nitroxin), integrative nutrition 2 (\mbox{50\,\%} vermicompost + \mbox{50\,\%} urea), supplementary chemical nutrition (\mbox{100\,\%} urea +fetrilon combi 2 micronutrient) and integrative supplementary nutrition (\mbox{50\,\%} nitroxin+\mbox{50\,\%} urea +fetrilon combi 2 micronutrient). Results indicated to significant effect of nutritional systems on almost all traits such as grain yield, biomass, number of capsule per plant, number of branches, capsule weight per plant, thousands seed weight, leaf dry weight, oil yield, oleic acid and linolenic acid (omega3) content. The highest grain yield (\mbox{703.08\,kg}.ha$^{-1}$) obtained under chemical nutrition system followed by integrated (\mbox{50\,\%} vermicompost +\mbox{50\,\%} urea) and supplementary integrative nutrition systems (nitroxin+ urea +fetrilon combi2). Overall, these results suggest that application of supplementary integrative nutrition increased flax grain yield and improved quality ( \mbox{13.05\,\%} linoleic acid and \mbox{47.28\,\%} linilenic acid ) of flaxseed oil (\mbox{65.7\,\%} compare to control). This treatment produced the highest oil yield (\unitfrac[271.9]{kg}{ha}). Therefore it could be introduce as a good alternative for conventional methods of soil fertilisation and will be considered as forward step into the goals of sustainable agriculture.}
