In the years 2003-05 the quantity and structure of grain yield of nine spring wheat cultivars were assessed. The wheat was cultivated on two agrotechnical levels under soil conditions of a very good wheat complex. The agrotechnical levels comprised medium intensive and intensive technology which differed in nitrogen dose and application or no application of a retardant and fungicides. The quantity of spring wheat grain yield was significantly dependent on the year of cultivation, intensity of the technology and the cultivar. Average grain yield of the analyzed spring wheat cultivars cultivated on the higher agrotechnical level was 9.34 t/ha and was almost 11 percent larger that the yield obtained from medium intensive cultivation. In the group of the investigated cultivars, Zura produced the largest grain yield, on average 9.64 t/ha, whereas the other cultivars were yielding between 7 and 14 percent lower. The cultivar factor and the weather conditions significantly diversified the value of all elements of the grain yield structure, while the effect of technology intensity was apparent only for the number of ears per area unit
