Abstract. The purpose of this study was to evaluate the wheat from the next two years, the harvest of wheat and other cereal products. The favorable comparison was the 2007 wheat harvest, as characterized by a higher content of crude protein and lower content of crude fiber, lignin and cellulose. The amino acid is limiting the nutritional value of wheat and wheat product was lysine and threonine. Nevertheless, the second limiting amino acid, according to the standard for man was threonine (2007) and isoleucine (2008). Furthermore, the protein of wheat in 2008 was characterized by a higher nutritional value compared to the 2007 wheat protein expressed by the rate of Oser (EAAI), respectively, in 2008, according to the MH (95.6) and EC (65.9) and in wheat in 2007MH (83.5) andWE (57.5), comparable to the petals (MH – 85.3 andWE – 64.9). The lowest nutritive value was characterized by a flour, while the highest germ.
