The eleven field experiments with spring barley, spring wheat and the mixture: barley + wheat + oats were carried out in the period 1995-97. The grain yields and nitrogen rates efficiency of these cereal were determined. The spring wheat characterized the higher efficiency of nitrogen rates: 50 and 75 kg/ha, higher protein content in grain and lower yielding than spring barley and cereal mixture. The higher efficiency of cereal nitrogen rates was observed on poorer soils, or delayed sowing
