Four varieties of winter triticale (Meloman, Trapero, Rotondo and hybrid BOH 2415) were cultivated on wheat soils by using different doses of N fertilizers (0-120 kg/ha) in traditional (plow) and simplified (without plowing) cultivation systems. The indicators of N consumption from fertilizers were examd. by detn. of N content in grain and straw. High N utilization from fertilizers and significantly higher yields were recorded in the case of N fertilization at a dose of 90 kg/ha in plow cultivation and for hybrid BOH 2415 cultivar. A physiol. efficiency decreased with the increase of N fertilization from 90 to 120 kg/ha, while the agricultural efficiency did not differ significantly.
