A field study was conducted in 2005 and 2006 at the agriculture experiment station of the college of agriculture, Tarbiat Modares University. The type of design was randomised complete block with factorial arrangement and three replications. The treatments were four levels of nitrogen fertiliser (0, 92, 184 and \mbox{276\,kg} N ha$^{-1}$), three levels of integrated nitrogen fertiliser and manure application (\mbox{46\,kg} N ha$^{-1}$ + 2.5 ton ha$^{-1}$ farm yard manure (FYM), \mbox{92\,kg} N ha$^{-1}$ + 5 ton FYM ha$^{-1}$ and \mbox{138\,kg} N ha$^{-1}$ +7.5 ton FYM ha$^{-1}$) and thrree levels of organic fertilisation (5, 10 and 15 ton FYM ha$^{-1}$) along with three levels of irrigation (optimum irrigation (control), \mbox{75\,\%} crop water requirement and \mbox{50\,\%}). The results showed a maximum grain yield with the application of \mbox{138\,kg} N ha$^{-1}$ + 7.5 ton FYM ha$^{-1}$ under optimum irrigation. Maximum oil content of grain was found under optimum irrigation and the minimum oil content under 50\,\% of crop water requirement with \mbox{138\,kg} urea ha$^{-1}$ + 7.5 ton FYM ha$^{-1}$. The greatest oil yield at first and second year was produced with \mbox{138\,kg} N ha$^{-1}$ + 7.5 ton FYM ha$^{-1}$ and least was produced with control. The results showed the greatest and least amount palmitic, stearic and oleic acids were produced when \mbox{50\,\%} crop water requirement and optimum irrigation, also maximum and minimum amount linoleic and linolenic acid were produced when optimum irrigation and \mbox{50\,\%} crop water requirement respectively. The best percentage oleic acid obtained in integrated and organic farming. From three fatty acid composition may offer several health benefits (oleic, linoleic and linolenic acid) with increased nitrogen levels increased. Also in between fatty acid composition oleic and linolenic acid were produced maximum amount in organic farming. Corn oil with higher levels of monounsaturated reduces blood cholesterol levels, thereby reducing the incidence of cardiovascular diseases. Such corn oil is also more chemically stable than conventional corn oil because it is less susceptible to oxidation. The use of corn with a greater content of monounsaturated may improve }
