An agrotechnical field trial with two new varieties of spring triticale, SGU-164 and SGU-181, was established. Three variants of N-fertilization were applied (30, 60, 90 kg N.ha**-1) and two methods of soil cultivation, i.e. conventional (ploughing to 0.15 m) and no-till (stubble ploughing). The spring wheat variety Saxana was used as the control. The yields were evaluated, technological analysis of the grain was performed for volume weight, proportion of 2.5 mm grain, crude protein content, gluten, falling number, SDS-test, flour yield, rheological properties of dough and amylographic evaluations. Grain yields were statistically significantly affected by weather in the individual years. Based on total average values the highest yield was 4.25 t.ha**-1in 1995, 3.45 t.ha**-1 in 1996 and the lowest in 1997, i.e. 3.02 t.ha**-1. The no-till method improved yields only moderately (on average, by 0.13 t.ha**-1). The effect of 60 and 90 kg N.ha**-1 of N-fertilizers was statistically significant (3.66 and 3.87 t.ha**-1, resp.); the dose of 90 kg/N evidently increased yields only in 1997. Compared with the control wheat, the average yields of triticale were higher by 18.2%.
