Weende analysis and analysis of minerals and amino acid composition were done on the defined cereal and maize samples harvested in Slovenia in 1997. Analyses were done on 5 varieties of wheat: Pinka, Ana, Marija, Reska and zitarka; 2 varieties of winter barley Alpha in Robur and 2 varietis of spring one: Rex and Gotic; 3 varieties of oats: Valiant, Pram and Leanda and 5 hybrids of maize: Fanion, Dea; Helga, Alberta and Lotus. The results of chemical analyses showed a relatively small degree of variability among wheat varieties. The same was found for barley varieties. Valiant is the variety that has less crude protein and ether extract and more crude fibre than the other varieties of oats. The maize hybrid Fanion is the one that has more crude protein and ether extract than the others. Cereals harvested in Slovenia have different average values for individual nutritive substance as they are cited in literature. The highert difference isfound in lower crude protein content in our samples. Mineral (P, Ca, Mg, K, Na, Zn and Mn) composition is similar among the varieties of the cereals or maize and the average values are in the accordance with the literature, except lower Na concentrations. Amino acid composition shows a lowdegree of variability among the varieties of the same cereal or maize. The concentration of some essential amino acids in protein is superior to the data cited in literature.
