The grain of 5 triticale cultivars grown at Jelcz Laskowice was analysed in experiments over 3 years (1986-89). Seed was sown after complete postharvest and pre-sowing cultivation treatments following typical cereal growing technology. In autumn, phosphorus-potassium fertilization at 70 kg P2O5 and 100 kg K2O/ha was applied. In spring, when vegetative growth started and at shooting, nitrogen was applied in the form of ammonium nitrate at doses of 40 kg N/ha. Nitrogen was also applied on a half of each plot at 40 kg N/ha at heading. Increased nitrogenous fertilization of triticale cultivars was found to positively influence 1000-grain weight, vitreousness and sedimentation value. Moreover, it decreased flour yield, falling number, maximum viscosity of flour paste and deterioration of crumb porosity. Some traits, such as falling number and flour paste viscosity, were also affected by cultivar, while others, such as rheological properties of the dough and baking quality, were unaffected by either c
ultivar or nitrogen fertilization.
