The experiment was conducted at an Experimental Station in Sanok, owned by PWSZ, during a period from 2008 to 2009. The research material were four corn hybrids; they differed in early sowing terms and in type of grain variety. Compared were the following agricultural engineering factors: mineral fertilization method, early sowing class of hybrids: medium early and medium-late sowing and also, the type of _flint and dent-grain variety. In the samples of large grains gathered, the weight of grain and of germ were assessed. It was found that, regardless of the grain type, the increase in the grain weight of the varieties analysed was highly significant and correlated with the weight of germ. The increase in the grain weight and in the germ weight decided on the increase in the oil yield per one unit area. It was found that the oil from corn germs was characterized by a high content of linoleic acid in the fatty acid profile
